The short answer
Grant writers typically charge $75–$125 per hour, with a typical rate around $100. Simple letters of inquiry sit lower; complex federal proposals sit higher. Many also offer flat project fees. The market spread:
| Tier | Range | What you get |
|---|---|---|
| Newer writer | $40–$70 | Small foundation grants, letters of inquiry, straightforward asks. |
| Experienced writer | $70–$120 | Full proposals, budget narratives, competitive foundation grants. |
| Specialist | $120–$160 | Federal grants, research or program-heavy proposals. |
| Retainer / grants strategy | Flat monthly | Ongoing prospect research plus a pipeline of submissions. |
What actually moves the price
Grant complexity. A one-page foundation letter is quick. A federal proposal with a logic model, detailed budget, evaluation plan, and strict formatting can run dozens of hours. The type of grant, not just the dollar amount you’re seeking, sets the effort.
Never pay a percentage of the award. This matters: professional and ethical standards discourage grant writers from charging a percentage of grants won, and many funders prohibit it. Pay hourly or a flat project fee. If someone quotes “a cut of what we get,” treat it as a red flag.
Research included or not. Some writers only draft what you hand them; others research prospects, match you to funders, and manage deadlines. That prospecting work is valuable but expands scope — clarify whether it’s in the quote.
