Short answer
Opportunity win rate, or close rate, is the percentage of sales opportunities that end as closed-won out of all opportunities closed in a period. It is calculated as won deals divided by won plus lost deals. It reveals sales effectiveness and pipeline quality, and is essential for forecasting how much pipeline is needed to hit targets.
