Win Rate = Closed-won deals / (Closed-won + Closed-lost) deals. Open deals don't count (they're not yet a Win or Loss).
Indian B2B SaaS win rates: SMB 15-25%, Mid-market 25-35%, Enterprise 30-50%. Higher win rates for incumbents and recommended-by-customer paths. Lower for outbound-cold prospects.
Win rate is more diagnostic than indicative — track it by source (paid ads vs referrals vs outbound), by lead score, by AE, by deal stage. Patterns reveal which channels and people are underperforming.
