Win rate is a fundamental sales metric that measures the percentage of opportunities that result in a closed-won deal. It is calculated by dividing the number of deals won by the total number of opportunities that reached a decision stage (won plus lost), then multiplying by 100. A typical B2B win rate ranges from 15% to 30%, though this varies significantly by industry, deal size, and sales motion.

Win rate is one of the most important indicators of sales team effectiveness. A high win rate suggests strong qualification, compelling messaging, and effective deal execution. A low win rate may indicate problems at various stages poor prospect targeting, weak discovery, inability to differentiate from competitors, or pricing misalignment. Tracking win rate over time and segmenting it by rep, product, deal size, or lead source reveals where improvements will have the greatest impact.

Improving win rate starts at the top of the funnel. When sales teams target the right prospects with accurate contact data, they create better-qualified opportunities that close at higher rates. Better targeting means fewer wasted opportunities and a more efficient sales process.
