Grant writers send a quote or proposal before any work begins, usually after a discovery call where you review the funder's guidelines, the nonprofit's readiness, and the deadline. Clients often compare your fee against other freelancers, agencies, or the cost of using staff time, so the quote needs to show what is included and what is not.
When to use estimates: Use estimates to provide project quotes and get client approval before starting work. Once approved, convert your estimate to an invoice with one click to collect payment.

The scope depends on the funder's requirements, and a fixed deadline determines whether rush charges apply.
List narrative, budget narrative, logic model, letters of support drafts, and attachment prep so the client knows what they are paying for.
Financial statements, board lists, outcomes data, and letters of support are the most common causes of delay. Set due dates for each.
Limits unlimited edits and gives the client a clear review process, such as one draft and two consolidated rounds.
Some clients expect you to submit through Grants.gov or a foundation portal, which adds time and requires registration access.
Sets ethical and legal expectations before work starts and avoids clients assuming you work on success.
Keeps follow-on work from being assumed to be part of the original fee.
| Service | Priced | Typical range |
|---|---|---|
| Hourly grant writing, research, and editing | per hour | $50-150 |
| Grant prospect research report | flat fee | $300-1,500 |
| Letter of inquiry or short foundation application | flat fee | $300-1,000 |
| Full foundation proposal (5-15 pages with budget) | flat fee | $1,000-3,500 |
| Federal or state grant application (e.g., SAMHSA, HUD, NEA) | flat fee | $3,000-10,000 |
| Monthly development retainer | per month | $750-3,000 |
| Grant report or final evaluation narrative | flat fee | $300-1,200 |
| Grant strategy session or calendar planning | per session | $150-400 |
Typical US ranges. Rates vary by region, experience, and job size.
A 10-page foundation proposal for a returning grantee can take 8 hours, while a federal application with a data plan and evaluation section can take 60. Estimate hours per section and add time for research, calls, and revisions.
Present a research-and-outline package, a full draft, and a full draft plus submission. Clients with in-house staff may only want a draft to edit, and tiers let them choose without negotiating your rate.
Build in time for slow responses and new information. If the project depends on data you have not seen, state your assumptions and say the quote may change if they are wrong.
Accept the quote with a signed agreement and a 30-50% deposit. Deadlines are fixed, so your calendar is committed once you accept the work.
Use a flat fee when the scope is clear, such as a specific foundation proposal. Use an hourly estimate with a cap when the scope is uncertain, such as a program still being developed or a funder's guidelines not yet released.
Usually 14 to 30 days, or until a date tied to the deadline. If the application is due in three weeks, a quote that stays open for a month does not make sense because you may no longer have time.
Do not guarantee outcomes. Funding decisions are made by the funder. You can describe your experience and past success, but your quote should be for the work and make clear that results are not promised.
A short discovery call and a simple quote are normally free. For a complex federal application, a paid grant readiness assessment or prospect research phase can be quoted first and credited toward the full project if the client continues.
