About the Proposal Cost Calculator
Every proposal costs real money whether you win or lose.
This calculator shows your true cost per bid, cost per win — and the annual budget burned on losing efforts.
This calculator computes cost per proposal, annual bid spend, cost per win, and spend on losses.
Formula
Cost per Win = Annual Spend ÷ (Proposals × Win Rate) - P
- — Proposals per Year
- H
- — Hours per Proposal
- R
- — Blended Hourly Rate
- WR
- — Win Rate
Per-proposal cost combines internal hours at your blended loaded rate with external per-bid costs. Annualizing across your volume and dividing by wins yields cost per win.
How to use this calculator
- 1
Profile your bid factory
Proposals per year, team hours per proposal, blended hourly cost and external costs per bid.
- 2
Enter your win rate
Cost per proposal, annual spend, cost per win and loss-spend compute instantly.
- 3
Model better qualification
Add the win-rate lift from bidding earlier and more selectively.
Example calculations
Proposal cost analysis
Example 135 proposals, 60 hours, $85 blended rate, $500 external, 22% win rate, 4% lift.
- Cost per Win:
- $25.5K
- Spend on Losses:
- $152.9K
- Improved Cost per Win:
- $21.3K
Interpreting your results
At 35 proposals, $5,100 each and a 22% win rate, you spend roughly $178,000 a year to win about eight contracts.

Common mistakes to avoid
-
Using base salary only
Use fully-loaded blended rate (salary × 1.25).
-
Forgetting external costs
Bonds, translations, printing, and travel add up.
