Sales Close Rate Calculator
Free sales close rate calculator — see your proposal-to-close rate, lead-to-close rate, and how many proposals you need per deal.
Sales Close Rate Calculator
- Lead-to-close rate
- 3.0%
- Proposals needed per close
- 4.6
A healthy proposal-to-close rate sits between 20% and 35%. If lead-to-close is under 2%, the bottleneck is usually qualification, not closing skill.

About this tool
Close rate means two different things depending on where you measure it. This calculator reports both the proposal-to-close rate and the lead-to-close rate, which together tell you whether your bottleneck is qualification or closing.
The formula
Close rate = deals closed ÷ proposals delivered. Lead-to-close rate = deals closed ÷ leads worked. Proposals per close = proposals ÷ closes.
Worked example
Twelve closes from 55 proposals is a 22% close rate, or 4.6 proposals per deal. Against 400 leads worked, the lead-to-close rate is 3% — healthy, and it means the funnel is losing volume before the proposal stage rather than at the close.
Benchmarks
| Metric | Typical range | Notes |
|---|---|---|
| Proposal to close | 20–35% | Under 15% usually means proposals go out too early |
| Lead to close | 1–5% | Varies hugely by lead source |
| Proposals per close | 3–5 | Above 7 indicates weak qualification |
| Inbound demo to close | 10–25% | Product-led motions sit lower |
How it works
- Enter deals closed. Closed-won deals in the period.
- Enter proposals or demos delivered. How many opportunities reached the proposal stage.
- Enter leads worked. Total leads you touched in the same period.
