Vendor Concentration Risk = Spend on Top N Vendors / Total Spend x 100
Vendor Concentration Risk measures how much of your total spend in Ramp flows through a small number of vendors. Using Ramp transaction and bill payment records, it expresses the share of spend captured by your largest suppliers, so you can see whether your outflows depend on a narrow set of relationships. A high reading means a single vendor going down, raising prices, or changing terms would have an outsized effect on the business.

How to calculate vendor concentration risk
Why vendor concentration risk matters for Ramp users
Ramp captures every card transaction and bill payment in one place, which makes it the natural source for understanding where money actually goes. When a large share of spend sits with one or two vendors, the business carries hidden operational and pricing risk. If that supplier raises prices, fails an audit, or has an outage, there is no easy fallback and the finance team is exposed.
Tracking concentration turns that exposure into something you can manage. It tells you when to negotiate harder, when to diversify suppliers, and when a single relationship has grown large enough to warrant a formal contract and review. It also gives finance leaders a defensible answer when investors or auditors ask how resilient the cost base is.
Understand and act on vendor concentration risk with KPI Tree
Sync your Ramp transaction and bill payment data into your warehouse and compute Vendor Concentration Risk in KPI Tree by ranking spend per vendor over a rolling period. Place it in a metric tree alongside total spend and category spend so you can see which suppliers and categories drive the concentration, and link it to related cost and budget metrics to understand the wider picture.
Assign RACI ownership to your finance or procurement lead so there is a clear accountable owner, and set a monthly or quarterly review cadence in KPI Tree. When the metric crosses a threshold, the owner can trigger a vendor review, open negotiations, or onboard an alternative supplier before the dependency becomes a problem.

Average Transaction Value
Expense ManagementMetric Definition
Average Transaction Value = Total Spend / Number of Transactions
Average transaction value measures the mean monetary amount per expense transaction processed through Ramp. It provides a baseline for identifying unusual spending patterns and understanding typical purchase behaviour.
Card Spend Distribution
Expense ManagementMetric Definition
Card spend distribution breaks down total card expenditure by card type - physical, virtual, and department-level cards - and by spending band. It reveals how concentration or fragmentation of spend across card instruments affects control and visibility.
Budget Utilisation Rate
Expense ManagementMetric Definition
Budget Utilisation Rate = (Actual Spend / Budget Allocation) × 100
Budget utilisation rate measures the percentage of allocated budget that has been spent within the current period. It shows spending velocity and helps predict whether budgets will be over or under-utilised.
Bill Payment Cycle Time
Expense ManagementMetric Definition
Bill Payment Cycle Time = Average (Payment Execution Date − Bill Receipt Date)
Bill payment cycle time measures the average number of days from bill receipt to payment execution within Ramp Bill Pay. It captures the end-to-end efficiency of the accounts payable workflow, including approval routing and scheduling.
