Stage Conversion Rates

A stage conversion rate is the percentage of deals that successfully move from one stage to the next. If 200 deals enter Discovery and 120 advance to Proposal, the Discovery-to-Proposal conversion rate is 60%. This single number tells you more about your pipeline health than any CRM dashboard. It tells you where deals die. It tells you whether the problem is lead quality, sales execution, or product-market fit. And when it changes over time, it tells you whether your interventions are working.

Stage Conversion Rate = (Deals exiting to next stage) / (Total deals entering stage)

Example 5-Stage Pipeline:
  Lead → Qualified:     500 → 200  = 40% conversion
  Qualified → Discovery: 200 → 140  = 70% conversion
  Discovery → Proposal:  140 → 84   = 60% conversion
  Proposal → Negotiation: 84 → 50   = 60% conversion
  Negotiation → Won:      50 → 30   = 60% conversion

Overall Win Rate: 30 / 500 = 6%
Cumulative Conversion: 0.40 × 0.70 × 0.60 × 0.60 × 0.60 = 0.06 (6%)

The power of conversion math is that it makes pipeline problems visible and quantifiable. If your Discovery-to-Proposal rate drops from 60% to 45%, you know exactly where to investigate. Is the discovery process failing to uncover real pain? Are reps proposing to unqualified buyers? Is the product no longer competitive? The conversion rate does not answer the question, but it tells you precisely where to ask it.
