Short answer: professional grant writers charge in one of three ways: hourly, a flat fee per application, or a monthly retainer. They should not charge a percentage of the grant. The price depends far more on the funder than on page count. A short foundation proposal and a federal infrastructure application with a benefit-cost analysis are different jobs. This guide explains the pricing models, what drives cost, and the red flags to avoid.
Grant writing pricing models
| Model | How it works | Best for |
|---|---|---|
| Hourly | You pay for time spent. Many freelance grant writers bill somewhere around $50 to $150 an hour, depending on experience and specialty. | Edits, reviews, small proposals and unclear scopes. |
| Flat fee per application | One price for a defined deliverable. | Most applications. You know the cost up front. |
| Retainer | A monthly fee for ongoing research, writing and reporting. | Organizations applying for several grants a year. |
| Percentage or commission | A share of the award, paid only if funded. | Avoid. The Grant Professionals Association’s Code of Ethics prohibits it, and most funders will not pay for it. |
What drives the cost
- Funder type. Federal applications require more forms, budgets, compliance narratives and attachments than most foundation or corporate grants.
- Technical analysis. Infrastructure grants often need a benefit-cost analysis, economic impact data or engineering inputs. These are priced separately or bundled in.
- Readiness. If you already have budgets, data, letters of support and a clear project plan, the job is faster.
- Partners. Applications with several partners or co-applicants take more coordination.
- Timeline. Rush work costs more. Federal deadlines are fixed, so start early.
- Post-award work. Reporting, compliance and budget management are separate services. See grant management.

Need a grant writer who can also run the numbers for your project or grant?
GERC prepares benefit-cost, economic and fiscal impact, feasibility and grant work for agencies, developers and the primes that support them, and gives you a fixed quote.
Can grant funds pay the grant writer?
Usually not for the application you are writing. Under the federal Uniform Guidance, 2 CFR 200.460, proposal costs are generally treated as indirect costs of current operations, and costs from past periods can’t be charged later. The GPA Code of Ethics also says grant writer compensation should not be written into a grant unless the funder allows it. Plan to pay for grant writing from operating funds.
Red flags when hiring a grant writer
- A fee based on a percentage of the award, or “no win, no fee” offers.
- Guaranteed funding. No honest writer can promise an award.
- No samples, references or knowledge of your funder.
- A writer who won’t tell you who owns the finished application. You should.
- No clear scope, deliverables or revision limits in the agreement.
What a good quote includes
- The specific opportunity and deadline.
- What the writer delivers: narrative, budget justification, forms, attachments, submission support.
- What you must provide, and by when.
- Any technical analysis (BCA, economic impact, data) and its price.
- Fee, payment schedule and revision rounds.
What we would do in your position
- Pick the right grants first. A strong application to a good-fit funder beats ten rushed ones.
- Ask for a flat fee per application with the scope in writing.
- Bundle the technical work. If the grant needs a BCA or economic data, have the same team do both so the numbers and narrative match.
- Talk to us. GERC writes federal, state and foundation grants, including infrastructure grants that need benefit-cost analysis. Learn more about our grant writing services or book a consultation. Compare grants with contracts in grants vs government contracts.
Grant writing services pricing: frequently asked questions
How much do grant writing services cost?
It depends on the funder and scope. Grant writers typically charge hourly, a flat fee per application, or a monthly retainer. Federal applications and those needing technical analysis such as benefit-cost analysis cost more than short foundation proposals.
Should a grant writer charge a percentage of the grant?
No. The Grant Professionals Association’s Code of Ethics prohibits finder’s fees, commissions and percentage-based compensation, and most funders will not pay them.
Can I pay a grant writer with grant funds?
Generally not for the application being written. Under 2 CFR 200.460, proposal costs are usually treated as indirect costs of current operations, and the funder must allow any such charge.
Is a flat fee or hourly rate better for grant writing?
A flat fee works best for a defined application because you know the cost up front. Hourly billing suits reviews, edits and work whose scope is not yet clear.
Can a grant writer guarantee funding?
No. Funding decisions belong to the funder. Be cautious of anyone who guarantees an award.
