## Formula

Win rate = won ÷ (won + lost) × 100.

- Methodology: closed-opportunity win rate — open deals are excluded.
- Some teams divide by all opportunities created; that gives a lower figure and is a different metric.
- Count deals, not value; use average deal size for value.
- Win rate = won ÷ (won + lost) × 100.
- Inputs used: Opportunities won, Opportunities lost.

## Inputs

- Opportunities won
- Opportunities lost

## Worked example: A quarter

24 won, 56 lost.
1. 24 ÷ 80 = 30%.

## Common questions

### Should open deals count?

Not in this definition — they have no outcome yet. Check the formula, example, and limitations on this page before using the result for a real sales decision.

### Count or value?

This is by count. A value-weighted win rate divides won value by closed value.

### Is there a good benchmark?

Benchmarks vary widely by market, deal size and sales motion. This page shows only your own figure and does not judge it.

### How do I use the Win Rate Calculator?

Enter the required values for Opportunities won, Opportunities lost. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Win Rate Calculator use?

Win rate = won ÷ (won + lost) × 100. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.

### Can the Win Rate Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Closed deals only.
- Count-based.
- Results are educational estimates built only from the figures you enter. They are not personalised investment, tax, legal or accounting advice. Rates, growth and discount assumptions are always yours to choose.
- The result depends on the values you enter for this win rate calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
