52 metrics
Agent touches per ticket
Customer Support MetricsMetric Definition
Agent Touches per Ticket = Total Agent Touches / Total Tickets Resolved
Agent touches per ticket measures the average number of agent interactions required to resolve a single support ticket. It captures the efficiency of the resolution process and directly reflects the effort placed on both agents and customers throughout the support journey.
View metricAverage handle time (AHT)
Customer Support MetricsMetric Definition
AHT = (Total Talk Time + Total Hold Time + Total After-Call Work) / Total Interactions Handled
Average handle time measures the average total duration of a single customer support interaction, including talk time, hold time, and after-call work. It is one of the most widely tracked efficiency metrics in contact centres and support operations, directly influencing staffing models, cost forecasts, and service level planning.
View metricAverage reply time (ART)
Customer Support MetricsMetric Definition
ART = Total Time Between Customer Messages and Agent Replies / Total Number of Agent Replies
Average reply time measures the mean elapsed time between a customer sending a message and an agent responding within an ongoing support conversation. Unlike first response time, which covers only the initial reply, ART tracks responsiveness throughout the entire interaction, capturing the experience customers have after the conversation has started.
View metricAverage resolution time
Customer Support MetricsMetric Definition
Average Resolution Time = Total Resolution Time Across All Tickets / Total Tickets Resolved
Average resolution time measures the mean elapsed time from when a support ticket is created to when it is fully resolved and closed. It captures the end-to-end customer experience of getting an issue fixed, encompassing wait times, agent work time, escalations, and any back-and-forth exchanges required to reach a solution.
View metricCall abandonment rate
Customer Support MetricsMetric Definition
Call Abandonment Rate = (Abandoned Calls / Total Inbound Calls) x 100
Call abandonment rate measures the percentage of inbound calls where the caller disconnects before reaching a live agent. It is a direct indicator of whether a contact centre can meet demand, and every abandoned call represents a customer whose issue remains unresolved and whose patience has been exhausted.
View metricConversations per teammate
Customer Support MetricsMetric Definition
Conversations per Teammate = Total Active Conversations / Number of Active Agents
Conversations per teammate measures the average number of active support conversations each agent handles during a given period. It is a core workload and capacity metric that influences response times, resolution quality, agent wellbeing, and the overall cost efficiency of a support operation.
View metricEscalation rate
Customer Support MetricsMetric Definition
Escalation Rate = (Escalated Tickets / Total Tickets Handled) x 100
Escalation rate measures the percentage of support tickets that are transferred from one tier or team to a higher tier or specialist group for resolution. It reflects the gap between the issues customers raise and the ability of frontline agents to resolve them, making it a key indicator of agent readiness, process maturity, and product complexity.
View metricFirst response time (FRT)
Customer Support MetricsMetric Definition
FRT = Total First Response Times / Total Tickets With a First Response
First response time measures the elapsed time between a customer creating a support ticket and receiving the first substantive response from a human agent. It is the metric that shapes the customer's initial impression of the support experience and sets the tone for the entire interaction.
View metricKnowledge base views
Customer Support MetricsMetric Definition
Knowledge Base Views = Sum of All Article Page Views in Period
Knowledge base views is the total number of times self-service help articles are viewed within a given period. It is the foundational volume metric for understanding how customers engage with your help content and a leading indicator of self-service adoption and support deflection effectiveness.
View metricMost common issues
Customer Support MetricsMetric Definition
Issue Frequency % = (Tickets for Issue Type / Total Tickets in Period) x 100
Most common issues is a ranked distribution of support ticket types by frequency, revealing which problems generate the highest volume of customer contacts. It is the diagnostic metric that tells support and product teams where to invest to reduce ticket volume and improve customer experience.
View metricPercentage of positive votes
Customer Support MetricsMetric Definition
Positive Vote % = (Positive Votes / Total Votes) x 100
Percentage of positive votes measures the proportion of knowledge base article ratings that are positive, typically captured through "Was this article helpful?" yes/no prompts. It is the most direct signal of whether self-service content is actually solving customer problems.
View metricPredicted CSAT (P-CSAT)
Customer Support MetricsMetric Definition
P-CSAT = f(interaction signals, customer context, resolution data)
Predicted CSAT is a machine-learning-generated satisfaction score that estimates how a customer would rate a support interaction before they respond to a survey. It transforms CSAT from a retrospective sample into a real-time, comprehensive quality signal across 100% of interactions.
View metricRatio of views vs tickets submitted
Customer Support MetricsMetric Definition
Views-to-Tickets Ratio = Knowledge Base Views / New Tickets Submitted
The ratio of knowledge base views to tickets submitted measures how many self-service article views occur for every new support ticket created. It is the core metric for evaluating whether your self-service content is effectively deflecting tickets and reducing the load on human agents.
View metricTicket backlog
Customer Support MetricsMetric Definition
Ticket Backlog = Open Tickets at Start of Period + New Tickets Created - Tickets Resolved
Ticket backlog is the total number of unresolved support tickets at a given point in time. It is the stock metric that reveals whether a support operation has the capacity to keep up with incoming demand, and it is the earliest warning signal of a growing gap between ticket inflow and resolution throughput.
View metricTicket volume
Customer Support MetricsMetric Definition
Ticket Volume = Total New Tickets Created in Period
Ticket volume is the total number of new support tickets created within a defined period. It is the fundamental demand metric for support operations, determining staffing requirements, budget allocation, and the urgency of self-service and product quality investments.
View metricRepeat contact rate
Customer support metric
Customer Support MetricsMetric Definition
Repeat Contact Rate = (Customers with Multiple Contacts / Total Customers Who Contacted Support) x 100
Repeat contact rate measures the percentage of customers who contact support more than once about the same issue or within a defined time window. It is a direct measure of resolution quality: when a customer contacts support again, it typically means their problem was not fully resolved on the previous interaction. High repeat contact rates increase support costs, frustrate customers, and signal systemic issues in either the product or the support process.
View metricSelf-service success rate
Customer support metric
Customer Support MetricsMetric Definition
Self-Service Success Rate = (Queries Resolved via Self-Service / Total Support Queries) x 100
Self-service success rate measures the percentage of customer support queries that are resolved through self-service channels without requiring interaction with a human agent. These channels include knowledge bases, help centres, chatbots, FAQ pages, in-app guidance, and community forums. A high self-service success rate means customers can find answers independently, which reduces support costs, improves response times, and often provides a better customer experience than waiting for an agent.
View metricConversation resolution rate
Support effectiveness
Customer Support MetricsMetric Definition
Conversation Resolution Rate = (Resolved Conversations / Total Conversations) x 100
Conversation resolution rate measures the percentage of customer support conversations that are resolved, meaning the customer's issue is fully addressed and the conversation is closed. It captures the effectiveness of the support team at actually solving problems rather than simply responding to them. A high resolution rate indicates that the team is closing the loop on customer issues, while a low rate suggests that conversations are going unanswered, being abandoned, or left in limbo.
View metricAgent utilisation rate
Support capacity
Customer Support MetricsMetric Definition
Agent Utilisation Rate = (Time on Active Conversations / Total Available Time) x 100
Agent utilisation rate measures the percentage of an agent's available working time spent on active customer conversations. It captures how effectively support capacity is being used, balancing the need for productivity against the risk of burnout and declining service quality. The metric helps support leaders right-size their teams, plan shifts, and understand whether staffing levels match conversation demand.
View metricSupport cost per conversation
Support economics
Customer Support MetricsMetric Definition
Support Cost per Conversation = Total Support Costs / Total Conversations Handled
Support cost per conversation measures the total cost of running the support operation divided by the number of conversations handled. It captures the unit economics of customer support, providing a clear picture of how much each customer interaction costs the business. The metric is essential for budgeting, staffing decisions, channel strategy, and evaluating investments in automation and self-service.
View metricAgent performance analysis
Support quality and efficiency
Customer Support MetricsMetric Definition
Agent performance score = (Quality weight x Quality) + (Efficiency weight x Efficiency) + (Volume weight x Volume)
Agent performance analysis is the practice of measuring how effectively an individual support agent resolves customer issues across speed, quality and volume. It combines efficiency measures like handle time with quality measures like resolution and satisfaction. Done well, it separates agents who close tickets fast from agents who close them right.
View metricAgent productivity score
Output per available hour
Customer Support MetricsMetric Definition
Agent productivity score = Productive output / Available time
Agent productivity score is a measure of how much useful support work an agent completes relative to the time they are available to work. It rewards resolved contacts and active handling while penalising idle and unproductive time. The aim is to capture genuine output, not raw activity or hours logged.
View metricAgent specialisation analysis
Routing and skill concentration
Customer Support MetricsMetric Definition
Specialisation Index = Tickets in Primary Category / Total Tickets Handled
Agent specialization analysis is the study of how concentrated each support or sales agent is on a narrow set of issue types, products, or customer segments rather than handling everything. It shows whether your routing sends the right work to the right people. Done well, it lifts resolution speed and quality at the same time.
View metricArticle effectiveness score
Self-service content quality
Customer Support MetricsMetric Definition
Article Effectiveness Score = (Deflection Weight x Deflection Rate) + (Helpfulness Weight x Helpful Rate) + (Findability Weight x Search Click Rate)
Article effectiveness score is a composite measure of how well a single help centre or knowledge base article resolves the question it is meant to answer. It blends whether readers found it, whether it deflected a ticket, and whether they rated it useful. A high score means the article does its job without a person ever getting involved.
View metricCase resolution time
Time to resolution
Customer Support MetricsMetric Definition
Average case resolution time = Total resolution time across cases / Number of resolved cases
Case resolution time is the total elapsed time from when a support case is opened to when it is fully resolved and closed. It measures how long customers wait for an actual fix, not just a first reply. Shorter resolution time usually means happier customers and lower support cost, but only when cases are genuinely resolved rather than closed prematurely.
View metricContact engagement score
Weighted activity index
Customer Support MetricsMetric Definition
Engagement Score = Sum of (Signal Count x Signal Weight x Recency Factor)
A contact engagement score is a single weighted number that summarises how actively an individual contact is interacting with your product, emails, content, and people. It rolls many signals, such as email opens, logins, meeting attendance, and feature use, into one comparable figure so sales and customer success can rank contacts and act on the ones cooling off. The score is a proxy for intent and relationship health, not a guarantee of either.
View metricContact lifecycle analysis
Stage-by-stage movement
Customer Support MetricsMetric Definition
Stage Conversion Rate = (Contacts Advancing to Next Stage / Contacts Entering Stage) x 100
Contact lifecycle analysis measures how contacts progress through the defined stages of a relationship, from new lead through qualified, opportunity, customer, and advocate, including where they stall and where they fall out. Rather than a single conversion number, it shows the shape of movement across every stage so a team can see which transition is leaking. It is the view that turns a flat list of contacts into a flow you can manage.
View metricContact response time
Speed to first reply
Customer Support MetricsMetric Definition
Contact Response Time = Sum of (First Reply Time minus Inbound Time) / Number of Contacts Replied To
Contact response time is the elapsed time between a contact reaching out and the first meaningful human reply they receive. It is the clearest early signal of how responsive a sales or service team really is. Slow first replies cost deals and goodwill long before any other metric notices.
View metricContact segmentation analysis
Grouping contacts that behave alike
Customer Support MetricsMetric Definition
Segment Share = (Contacts in Segment / Total Contacts) x 100
Contact segmentation analysis is the practice of dividing a contact base into groups that share meaningful traits, then comparing how those groups behave. It turns one undifferentiated list into a map of who actually converts, spends, and stays. The point is not to label contacts but to act differently towards segments that behave differently.
View metricConversation abandonment rate
CAR
Customer Support MetricsMetric Definition
Conversation Abandonment Rate = (Abandoned Conversations / Total Conversations Started) x 100
Conversation abandonment rate is the percentage of started conversations that end before the customer reaches a resolution or a human agent. It measures how often people give up on a support chat, chatbot, or messaging channel without getting what they came for. A high rate points to friction, long waits, or a bot that cannot answer the question.
View metricConversation channel analysis
Channel mix and performance
Customer Support MetricsMetric Definition
Channel Share = (Conversations on Channel / Total Conversations Across All Channels) x 100
Conversation channel analysis is the practice of comparing how support conversations perform across each channel a customer can reach you on, such as email, live chat, phone, social and self-service. It reveals where volume concentrates, which channels resolve fastest, and which cost the most to operate. Done well, it turns channel strategy from a guess into a measured decision.
View metricConversation funnel analysis
Stage-by-stage resolution
Customer Support MetricsMetric Definition
Stage Conversion = (Conversations Reaching Next Stage / Conversations Entering Stage) x 100
Conversation funnel analysis is the practice of tracking how support conversations progress through the stages between open and resolved, measuring how many advance and how many stall at each step. It exposes where conversations get stuck, abandoned or bounced back. Instead of a single resolution number, it shows the shape of the path that leads there.
View metricConversation handoff analysis
Transfers between agents and teams
Customer Support MetricsMetric Definition
Handoff Rate = (Conversations With at Least One Transfer / Total Conversations) x 100
Conversation handoff analysis is the practice of measuring how often a support conversation is transferred from one agent, team or channel to another before it resolves. Each handoff adds delay, repetition for the customer and risk of context loss. The analysis exposes where handoffs cluster and which ones are avoidable, turning a hidden source of friction into something you can manage.
View metricConversation sentiment analysis
Sentiment score
Customer Support MetricsMetric Definition
Sentiment Score = (Positive Conversations - Negative Conversations) / Total Scored Conversations
Conversation sentiment analysis is the practice of scoring the emotional tone of customer conversations, usually on a scale from negative to positive, to measure how people feel while they interact with your team. It turns the qualitative texture of support chats, calls, and emails into a number you can track over time. When sentiment is decomposed into its drivers, it becomes a diagnostic for where the experience is breaking down.
View metricConversation topic analysis
Topic distribution
Customer Support MetricsMetric Definition
Topic Share = Conversations Tagged with Topic / Total Classified Conversations
Conversation topic analysis is the practice of classifying customer conversations into themes, then measuring how much of your contact volume each theme accounts for. It answers the question of what customers are actually contacting you about, in proportions you can act on. When topics are decomposed into their drivers, the analysis points to the upstream causes that generate the contacts.
View metricConversation volume
Contact volume
Customer Support MetricsMetric Definition
Conversation Volume = Sum of Conversations Opened Across All Channels in the Period
Conversation volume is the total number of customer conversations your team handles in a given period across every channel. It is the workload metric that sizes staffing, exposes demand spikes, and signals when something upstream is generating extra contacts. When decomposed into its drivers, conversation volume shows whether a rise comes from growth, seasonality, or a problem you can fix.
View metricConversation volume trends
Inbound contacts over time
Customer Support MetricsMetric Definition
Conversation Volume Trend = (Conversations This Period - Conversations Prior Period) / Conversations Prior Period x 100
Conversation volume trends measure how the number of inbound support conversations changes across consecutive periods. The trend matters more than any single period because it reveals whether demand on the support team is rising, holding, or falling before staffing and response times feel the strain.
View metricCustomer contact frequency
Touches per customer per period
Customer Support MetricsMetric Definition
Customer Contact Frequency = Total Customer Contacts in Period / Number of Active Customers
Customer contact frequency is the average number of times a business reaches out to or interacts with each customer over a defined period. It captures how often a customer hears from sales, success, support, and marketing combined. Tracked well, it tells you whether relationships are being nurtured, neglected, or smothered.
View metricCustomer journey support analysis
Support load by lifecycle stage
Customer Support MetricsMetric Definition
Stage Support Rate = Support Contacts in Stage / Active Customers in Stage
Customer journey support analysis is the practice of measuring how much support effort customers consume at each stage of their lifecycle, from onboarding through to renewal. It maps contact rates, ticket reasons, and resolution effort against journey stages so you can see where the experience breaks down. Instead of treating support as one undifferentiated queue, it shows you which moments create the most friction.
View metricCustomer segment support analysis
Support by segment
Customer Support MetricsMetric Definition
Segment Support Load = Segment Ticket Volume / Segment Active Customers
Customer segment support analysis is the practice of breaking support demand, cost, and outcomes down by customer segment so the team can see which segments cost the most to serve and which receive the worst experience. It replaces a single blended support average with a view that exposes where effort and satisfaction diverge. The output is usually a per-segment scorecard of volume, resolution time, cost, and satisfaction.
View metricCustomer support ticket analysis
Ticket analytics
Customer Support MetricsMetric Definition
Tickets per 100 Customers = (Total Tickets in Period / Active Customers) x 100
Customer support ticket analysis is the systematic study of support ticket data to understand demand, efficiency, cost, and the root causes behind why customers contact support. It moves a team beyond counting tickets towards explaining them, so the same data that measures workload also points to the product and process fixes that reduce it. The output is a set of linked metrics covering volume, resolution, cost, and category.
View metricEscalation pattern analysis
Finding the structure behind escalations
Customer Support MetricsMetric Definition
Escalation Rate = (Escalated Tickets / Total Tickets) x 100
Escalation pattern analysis is the study of which support tickets get escalated, why they escalate, and what those escalations reveal about gaps in your product, process, and team. Instead of treating each escalation as a one-off, it looks for recurring patterns across reason, product area, customer segment, and the path a ticket took before it moved up a tier. The output is a prioritised list of root causes you can fix at source rather than handling case by case.
View metricHelp center article views
Self-service demand signal
Customer Support MetricsMetric Definition
Help Center Article Views = Total Article Page Views in Period
Help center article views are the total number of times help centre articles are opened and read within a defined period. The metric measures how much of your support demand is being met by self-service content before a customer ever opens a ticket. It is the clearest signal of whether your documentation is actually being used.
View metricKnowledge gap identification
Finding what your content cannot answer
Customer Support MetricsMetric Definition
Knowledge Gap Rate = (Questions With No Adequate Documented Answer / Total Questions Asked) x 100
Knowledge gap identification is the practice of measuring how often questions reach a team or customer without a documented answer, then locating the topics where that documentation is missing. It turns scattered unanswered questions into a ranked list of content to create. The goal is to close the gaps that cost the most time and cause the most repeat contact.
View metricKnowledge transfer effectiveness
Does the knowledge actually stick
Customer Support MetricsMetric Definition
Knowledge Transfer Effectiveness = (Recipients Able to Apply the Knowledge Independently / Total Recipients) x 100
Knowledge transfer effectiveness measures how well knowledge moves from one person or team to another and is retained well enough to be applied independently. It is the difference between someone being told how something works and being able to do it without help. The metric tracks whether handovers, onboarding, and training produce capable people rather than just delivered material.
View metricMeeting sentiment analysis
Conversation tone scoring
Customer Support MetricsMetric Definition
Sentiment score = (Positive segments - Negative segments) / Total scored segments
Meeting sentiment analysis is the practice of scoring the emotional tone of a conversation, usually on a scale from negative through neutral to positive. It turns the qualitative feel of a meeting into a number you can track across calls, teams and accounts. The score is derived from transcripts, language cues and sometimes voice or facial signals, so a soft notion like mood becomes a measurable trend.
View metricOnboarding conversation rate
Activation through guided onboarding
Customer Support MetricsMetric Definition
Onboarding Conversation Rate = (New Users Who Engaged in Onboarding / Total New Users Who Started Onboarding) x 100
Onboarding conversation rate is the percentage of new users who actively engage in a guided onboarding exchange, such as a setup chat, walkthrough, or assisted first session, rather than dropping off in silence. It measures how well the first moments of the product turn a fresh signup into a participating user. A low rate signals that people sign up but never reach the moment where the product starts to make sense.
View metricPeak support hours analysis
When contacts concentrate
Customer Support MetricsMetric Definition
Peak Hour Contact Share = Contacts in Busiest Hour / Total Daily Contacts x 100
Peak support hours analysis is the practice of measuring how inbound support contacts distribute across the hours of the day so you can find the windows where volume concentrates and queues build. It converts a flat daily contact total into an hourly arrival profile. That profile drives shift planning, service level forecasts, and agent coverage in a way a daily total never can.
View metricProactive support effectiveness
Prevented-contact rate
Customer Support MetricsMetric Definition
Proactive Support Effectiveness = (Prevented Contacts / Proactive Outreaches) x 100
Proactive support effectiveness is the share of potential support contacts that are prevented or resolved by reaching out to customers before they raise a ticket. It measures whether proactive outreach actually reduces inbound demand rather than just adding noise. A high score means the team is solving problems upstream instead of waiting for them to land in the queue.
View metricSupport cost per contact
Cost per contact
Customer Support MetricsMetric Definition
Support cost per contact = Total support cost / Number of contacts handled
Support cost per contact is the total cost of running a support operation divided by the number of customer contacts it handles. It tells you what each ticket, call or chat actually costs to resolve. Because it is fully loaded, it captures the real economics of support rather than just headline salaries.
View metricSupport ticket escalation rate
Escalation rate
Customer Support MetricsMetric Definition
Support Ticket Escalation Rate = (Escalated Tickets / Total Tickets Handled) x 100
Support ticket escalation rate is the percentage of support tickets that frontline agents cannot resolve and must transfer to a higher tier, specialist team, or another department. It exposes the gap between the issues customers raise and what your first line of support can actually close. A rising rate usually points to training gaps, thin documentation, or a recent product change that frontline agents are not yet equipped to handle.
View metricSurvey response analysis
Response rate and signal quality
Customer Support MetricsMetric Definition
Survey Response Rate = (Completed Responses / Invitations Delivered) x 100
Survey response analysis is the practice of measuring how many people complete a survey and turning their answers into a reliable, representative read on what your audience thinks. It combines a quantitative response rate with the quality and balance of the responses you receive. A survey with a low or skewed response rate produces conclusions that look precise but do not represent the population you care about.
