Freelance grant writers often quote a flat fee per proposal and absorb the research, funder calls, and revision cycles as unpaid time. This calculator turns the take-home you want into an hourly floor you can convert into per-proposal pricing.

This tool does math on the numbers you enter. It is not tax or financial advice and contains no built-in tax tables — enter your own effective rate (a tax professional can help you estimate it). Figures are estimates for planning only.

Benchmarks are gathered from public salary and marketplace data and refreshed periodically. Treat them as orientation — your required rate from the calculator above is the number that matters for your situation.
The most common pricing mistake is dividing a target salary by 2,080 hours. That ignores three things every freelancer carries: self-employment tax, business expenses (grant databases and prospect-research subscriptions, proposal and CRM tools, professional association dues, continuing education), and the large share of the week that is never billable. This calculator builds all three in, then solves for the rate that leaves you with the take-home you entered.
US freelance grant writers commonly bill $40–$200/hour, with a mid-market average near $75 and federal-grant specialists at the top. Per-project fees are common, but compute your hourly floor here first so flat proposal fees don't drop below cost.
Charging a contingency fee tied to award amounts is widely considered unethical by professional associations and barred on many federal grants. Price your work on time and expertise instead — use the hourly rate above as the basis for flat or retainer fees.
Estimate the hours a proposal truly takes — research, narrative, budget, revisions — multiply by your required hourly rate, and add a buffer. Lowering the billable percentage above also reflects the unbilled funder communication around each grant.
