What is win rate?
Win rate is the percentage of sales opportunities that a team or individual closes successfully. It is calculated by dividing the number of closed-won deals by the total number of deals that reached a final outcome (won plus lost), excluding deals still in progress.
Win rate is arguably the most important metric in sales because it measures the core competency of the sales function: converting pipeline into revenue. A high win rate means the team is effectively qualifying opportunities, positioning the product, managing objections, and navigating the buying process. A low win rate means one or more of these areas is failing.
The metric also has enormous financial implications. If a sales team generates one hundred opportunities per quarter at an average deal size of fifty thousand pounds, the difference between a 20% win rate and a 30% win rate is five hundred thousand pounds in additional revenue, with no increase in pipeline generation cost.
Win rate can be calculated at multiple levels: team-wide, by individual rep, by deal size, by customer segment, by lead source, or by competitor. Each view reveals different insights. Team-wide win rate shows overall effectiveness. Rep-level win rate identifies top performers and those who need coaching. Win rate by deal size often reveals that larger deals close at lower rates. Win rate by competitor shows where you have positioning advantages and disadvantages.
The denominator matters: win rate should be calculated against total closed deals (won plus lost), not against all open pipeline. Including open deals in the denominator depresses win rate and makes it dependent on pipeline age rather than actual sales performance.
How to calculate win rate
Win rate is calculated by dividing closed-won deals by total closed deals (won plus lost) and multiplying by 100. If a rep closed fifteen deals and lost ten in a quarter, their win rate is 15 / (15 + 10) x 100 = 60%.
The key decision in calculating win rate is defining the denominator. There are two common approaches. The first, and more accurate, uses only deals that reached a final outcome: won or lost. This measures sales execution quality because it only includes deals where the sales team fully engaged. The second approach includes all opportunities created in a period, including those that went stale or were disqualified. This produces a lower win rate but captures pipeline quality issues.
Both approaches have value, and many organisations track both. The won-vs-closed rate measures sales execution. The won-vs-created rate measures the combined quality of pipeline generation and sales execution. If the first is strong but the second is weak, the issue is pipeline quality, not sales capability.
| Calculation method | Formula | What it measures |
|---|---|---|
| Win rate (closed basis) | Won / (Won + Lost) | Sales execution quality on deals that fully progressed |
| Win rate (created basis) | Won / All opportunities created | Combined pipeline quality and sales execution |
| Win rate by value | Won revenue / (Won + Lost revenue) | Revenue-weighted effectiveness |
Win rate in a metric tree
Win rate is a central node in the revenue metric tree, sitting between pipeline generation and closed revenue. It amplifies or diminishes the value of every pound invested in pipeline creation.
The tree reveals that win rate is driven by three categories of factors. Deal qualification quality determines whether the opportunities entering the pipeline are winnable. Sales execution quality determines whether the team effectively progresses and closes those opportunities. Competitive positioning determines whether the product holds up against alternatives.
If win rate drops, the tree guides diagnosis. Are we losing more deals to competitors (a positioning problem)? Are we losing deals that stall and go dark (a qualification or champion development problem)? Are we losing at the proposal stage (a pricing or value communication problem)? Each diagnosis leads to a different intervention.
Win rate benchmarks
| Context | Typical win rate | Notes |
|---|---|---|
| B2B SaaS (overall) | 20% to 30% | On a created-basis. Closed-basis win rates are typically 35% to 50%. |
| SMB deals (<£25k ACV) | 25% to 40% | Shorter cycles and simpler buying processes support higher win rates. |
| Mid-market (£25k to £100k) | 20% to 30% | More stakeholders and procurement involvement. |
| Enterprise (>£100k) | 10% to 25% | Complex, multi-stakeholder deals with long cycles. |
| Top-performing reps | 35% to 50%+ | Best reps consistently win at 1.5x to 2x the team average. |
A win rate that is "too high" might indicate the team is not pursuing enough stretch opportunities, or is only working deals that are virtually guaranteed. If win rate exceeds 50% on a closed basis, consider whether the team could be more ambitious in the deals they pursue.
How to improve win rate
- 1
Improve deal qualification early
The most impactful way to improve win rate is to stop working unwinnable deals. Implement rigorous qualification criteria (BANT, MEDDIC) and give reps permission to disqualify early. A smaller pipeline of winnable deals beats a large pipeline of wasted effort.
- 2
Invest in discovery and champion development
Reps who deeply understand the buyer's pain, decision process, and stakeholder dynamics win more often. Train the team on discovery techniques and the importance of building an internal champion who advocates for your solution.
- 3
Build competitive battle cards
Reps who know how to position against specific competitors win more head-to-head evaluations. Create and regularly update battle cards that address competitive strengths, weaknesses, and common objections.
- 4
Coach based on deal review, not just outcomes
Regular deal reviews where managers examine strategy, stakeholder mapping, and next steps help reps course-correct before deals are lost. Focus coaching on the process, not just celebrating wins and post-morteming losses.
- 5
Analyse lost deals for patterns
Categorise loss reasons (pricing, competition, no decision, timing) and track trends. If most losses are to "no decision," the issue is likely qualification or urgency creation. If most losses are to a specific competitor, the issue is positioning.
Common mistakes with win rate
Inflating win rate by not logging losses
If reps delete lost opportunities instead of marking them as lost, win rate appears artificially high. Enforce CRM hygiene and make it safe to log losses without negative consequences.
Not segmenting by deal size or segment
A blended win rate across SMB and enterprise deals hides important differences. Segment win rate by deal size, customer segment, lead source, and competitor to get actionable insights.
Comparing win rates across teams with different pipeline quality
A team that receives hand-raised demo requests will have a higher win rate than a team that relies on outbound prospecting. Compare win rates only when pipeline quality is comparable.
Ignoring the "no decision" category
Deals lost to "no decision" are often the largest category and the most fixable. These are prospects who had a need but did not act. Understanding why they stalled is often more valuable than understanding why you lost to a competitor.

Sales Pipeline Velocity
Sales MetricsMetric Definition
Pipeline Velocity = (Opportunities × Deal Value × Win Rate) / Sales Cycle Length
Sales pipeline velocity measures how quickly deals move through your pipeline and generate revenue. It combines the four core levers of sales performance into a single metric that reveals the rate at which your pipeline converts to closed revenue.
Sales Cycle Length
Sales MetricsMetric Definition
Sales Cycle Length = Sum of Days to Close for All Deals / Number of Deals Closed
Sales cycle length measures the average number of days from the creation of a sales opportunity to its close. It is a key efficiency metric that directly affects pipeline velocity, revenue forecasting accuracy, and the cost of sales.
Average Deal Size
Sales MetricsMetric Definition
Average Deal Size = Total Revenue from Closed Deals / Number of Closed Deals
Average deal size measures the mean revenue value of closed-won deals. It is a fundamental sales metric that directly influences pipeline velocity, quota planning, and the economics of your go-to-market model.
Quota Attainment
Sales MetricsMetric Definition
Quota Attainment = (Actual Revenue Closed / Quota Target) × 100
Quota attainment measures the percentage of a sales target that a rep or team achieves in a given period. It is the primary performance metric for sales organisations, connecting individual and team output to revenue goals.
