Stage conversion rates measure how efficiently deals move from one stage to the next in a pipeline (sales, marketing, recruitment, etc.). They tell you what percentage of opportunities successfully advance at each step.
The Formula
Conversion Rate = (Number entering next stage ÷ Number entering current stage) × 100
For example, if 200 leads become Marketing Qualified Leads and 50 of those become Sales Qualified Leads: 50 ÷ 200 × 100 = 25% conversion rate for that stage.
Example: A Typical Sales Pipeline
Stage | Count | Conversion to Next |
Raw Leads | 1,000 | 20% |
MQLs | 200 | 25% |
SQLs | 50 | 60% |
Proposals Sent | 30 | 50% |
Closed Won | 15 | — |
Why They Matter
Identify bottlenecks: a dramatically low rate at one stage signals a problem worth fixing
Forecast revenue: if you know your rates, you can work backwards from a revenue target to figure out how many leads you need
Benchmark performance: track changes over time or compare reps/channels against each other
Prioritize investment: improving a low-converting stage often has more leverage than adding volume at the top
Things to Watch Out For
Time periods matter: make sure the leads entering and exiting a stage fall within the same window, or you'll get distorted numbers
Volume vs. rate trade-offs: a high conversion rate on tiny volume isn't necessarily better than a moderate rate on large volume
Stage definitions: if your team defines stages inconsistently, the numbers won't be comparable
