Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Win rate | Loss rate |
|---|---|---|
| 24 of 80 deals | 30.00% | 70.00% |
| 8 of 25 deals | 32.00% | 68.00% |
| 60 of 150 deals | 40.00% | 60.00% |
| 3 of 40 deals | 7.50% | 92.50% |
How This Calculator Works
Enter the number of deals won and the total opportunities closed during the period — wins plus losses. The calculator divides one by the other and multiplies by 100 to give the win rate, then shows the complement — the loss rate.
The Formula
Part as a Percentage of a Whole
Part is the portion, Whole is the total it belongs to
Worked Example
Closing 24 wins out of 80 opportunities is a 30% win rate, with a 70% loss rate. Pair the win rate with average deal size and pipeline volume to project revenue: 30% win rate × 100 opportunities × $20,000 average = $600,000.
Key Insight
Win rate by itself can mislead. A 40% win rate on tiny deals can be worth less than a 20% win rate on enterprise ones — always read it alongside average deal size and the volume of opportunities feeding the funnel.
Frequently Asked Questions
How is win rate calculated?
Divide deals won by total opportunities closed during the period, then multiply by 100. Twenty-four wins from 80 closed opportunities is a 30% win rate.
Should open deals be included?
No. A win rate uses closed opportunities only — wins plus losses. Including deals still in pipeline understates the rate, because not-yet-won and lost get bundled together.
What is a good win rate?
It varies hugely by segment and deal size. Transactional inbound teams can post 40% to 60%; complex enterprise sales are often in the teens. Compare against your own past rate first.
How does win rate relate to forecasting?
It is the conversion factor that turns pipeline into revenue. Forecast = opportunities × win rate × average deal size, so an accurate win rate is the difference between a useful forecast and a wish.
Should I track win rate by source?
Yes. Win rates differ by lead source, segment, and rep. A blended rate hides which channels and which sellers are actually carrying the result.

Methodology & Review
The win rate is deals won divided by total opportunities closed in the period, multiplied by 100. The complement is the loss rate. Open opportunities still in the pipeline are excluded — only closed deals count.
