How to use

  1. Enter Won proposals.
  2. Enter Proposals sent.
  3. Calculate, then review the period, scope and assumptions before using the result for pricing or planning.

How it is calculated

Win rate = won proposals ÷ proposals sent × 100

Example

Winning 8 out of 20 proposals gives a 40% win rate and leaves 12 proposals not won or still open.

Important notes

Define how open proposals are treated before comparing periods; counting them as losses too early can make the rate look worse without a real performance change.

Frequently asked questions

Should withdrawn or cancelled proposals count?

Use a consistent policy; excluding proposals that never reached a real decision may be more accurate, but apply the rule consistently.

Is the result a mandatory client price?

No. It is a planning result from your inputs; final pricing depends on scope, market, contract, taxes and risk.

Should I use monthly or annual figures?

Keep all inputs on the same period so annual income is not mixed with monthly hours or expenses.
