Proposal win rate calculator

Every proposal you write is unpaid work bought with your hourly rate. This prices the chase: what a proposal costs, what a win really costs once the losses are amortized, and what is left of the project after.

Estimate

The formula

Cost per win = proposal cost × sent ÷ won. Expected value per proposal = win rate × average project. When cost per win approaches project value, you are buying work at retail.

What this ignores

Proposal quality differences, relationship value of near-misses, and selection effects: a low win rate sometimes means brave targeting, not bad proposals. Read the trend, not one quarter.

FAQ

What is a healthy proposal win rate?
For inbound leads, 40-60%; for cold or competitive RFPs, 10-25%. Below 20% on warm inquiries usually signals a qualification problem: you are proposing to people who were never going to buy.
How do I cut the cost per win?
Qualify harder before writing (a 15-minute call kills bad fits cheaply), template the 80% that repeats, and charge for detailed scoping on large projects. Winning more of fewer proposals beats sending more.
Should I ever charge for a proposal?
For serious scoping work, yes: call it a paid discovery or roadmap engagement. Clients who refuse to pay for a plan tend to be the ones who dispute invoices later. Small quotes stay free.
