Win rate calculator
This win rate calculator returns your win rate from the deals you won and lost, and a second, stricter win rate that also counts deals that ended with no decision. Enter the counts for one period and one segment.
Win rate calculator
Formula: won / (won + lost). With no-decision deals counted: won / (won + lost + no decision).
The formula
Win rate = deals won / (deals won + deals lost)
With no-decision deals counted as losses:
Win rate, strict = deals won / (deals won + deals lost + no decision)
Use the same period and the same segment for every term: a quarter, a region, a deal size band. Mixing a quarter of wins with a year of losses gives a number that means nothing.
Worked examples
| Team | Won | Lost | No decision | Win rate | Strict win rate |
|---|---|---|---|---|---|
| A | 18 | 42 | 10 | 30% | 25.7% |
| B | 18 | 22 | 30 | 45% | 25.7% |
| C | 40 | 60 | 0 | 40% | 40% |
Teams A and B have the same strict win rate. Team B looks much better on the usual definition only because 30 deals ended with no decision: the buyers did not pick a competitor, they picked nothing. That is a pipeline quality problem, not a sales skill.
Pull the numbers from your CRM
- Create an opportunities report filtered on close date in the period.
- Group by stage, or by a "closed reason" field if you record no-decision outcomes.
- Count Closed Won, Closed Lost, and the closed-lost reasons that mean no decision.
- Enter the three counts above.
If no-decision outcomes are not recorded, add a closed-lost reason for them. Without it, the strict win rate cannot be measured.
What to do with the result
- Size the pipeline. The coverage you need is 1 / win rate: 4x at 25%, about 3.3x at 30%, 2.5x at 40%. The pipeline coverage calculator does the rest.
- Compute velocity. Win rate is one of the four inputs of the sales velocity calculator.
- Check the forecast. A win rate that drops while the forecast holds is a warning sign; measure it with the forecast accuracy formula.
Why win rate falls when the pipeline is not clean
Deals that sit open for months without activity usually end as losses or no decisions. When they finally close, they lower the win rate of the quarter they land in, long after they stopped being real. Removing them from the pipeline early does not change the outcome; it makes the forecast honest sooner.
Frequently asked questions
How do you calculate win rate?
Win rate is deals won divided by deals won plus deals lost, over the same period. With 18 won and 42 lost, the win rate is 18 / 60 = 30%.
Should no-decision deals count in the win rate?
Both conventions exist, so say which one you use. Counting no-decision deals as losses gives a lower, more conservative win rate; excluding them measures only the competitive outcome.
What is the difference between win rate and close rate?
Many teams use the terms interchangeably. When they differ, close rate usually divides wins by all opportunities created in a period, including deals still open, which makes it lower.
Why does win rate matter for pipeline coverage?
The pipeline you need is the target divided by the win rate. At a 25% win rate you need 4 times the target in pipeline, not the usual 3 times.
Is a win rate calculator useful for trading or games too?
The arithmetic is the same: wins divided by wins plus losses. This page's examples and CRM steps are written for B2B sales deals.
