The percentage of qualified opportunities that close as won — the single clearest signal of sales system health in a B2B company.
Also known as:
Close Rate, Opportunity Win Rate
Win rate is the ratio of closed-won deals to total qualified opportunities that reach a defined pipeline stage — typically from SQL or Stage 1 onwards. It is the cleanest lag indicator of how well the sales system is working: ICP fit, value messaging, qualification rigour, champion development, and competitive positioning all show up in win rate before they show up anywhere else.
Win Rate = Closed-Won Opportunities ÷ (Closed-Won + Closed-Lost Opportunities). Calculate it by rep, by segment, by deal source, and by ICP fit — not just in aggregate. Aggregate win rate hides the patterns that tell you what to fix.
Win rate improves when three things align: the right opportunities enter the pipeline (ICP and qualification), value is communicated in terms the economic buyer acts on (discovery and commercial case), and deals are progressed with buyer evidence rather than seller activity. Stage-gated playbooks, structured discovery, and champion development are the levers — not more activity or more calls.
A win rate below 20% in a competitive B2B market typically signals ICP or messaging problems. A win rate above 35% often signals the pipeline is too narrow. The goal is a defensible win rate that improves as the system matures, not a number that fluctuates with rep tenure.
