Sales Win Rate Calculator

Calculate the proportion of contested deals your team wins, the cleanest measure of sales effectiveness.

About Sales Win Rate Calculator

The win rate is the share of deals contested that deals won represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.
