What is sales win rate?
Sales win rate is the share of decided deals you win: deals won divided by all deals that closed, won or lost. A 25% win rate means you close one in four of the deals that reach a decision.
It is the cleanest read on sales effectiveness. Some teams measure it against all opportunities created instead of decided deals, which lowers the number, so be clear which denominator you use.
The win rate formula.
Win rate = deals won divided by (deals won plus deals lost), as a percentage. The alternative is deals won divided by total opportunities created, which counts open and stalled deals against you.
Pick one definition and hold it. Comparing a closed-deal win rate to an all-opportunity one is comparing two different numbers.
A worked example.
In a quarter you win 25 deals and lose 75. Win rate is 25 divided by 100, which is 25%.
What is a good win rate?
For B2B SaaS new business, 20 to 30% is typical. Inbound and warm deals win at a higher rate than cold outbound, so judge by source. A blended win rate hides the difference between a 40% inbound rate and a 10% outbound one.
A low win rate is often a qualification problem, not a closing one. If deals die late, look at fit at the top of the funnel, not just the final stage.
How to improve your win rate.
Win rate rises when the deals you work are a better fit. Tighter qualification and better-matched prospects close at a higher rate than volume alone.
