You want a number. I understand why, and I am going to give you the useful version of one, which is the structure of the cost and what moves it, rather than a figure that would be wrong for most of the people reading this.
Here is the problem with a flat answer. A two-page letter of inquiry to a family foundation and a three-year federal application with a match requirement, a compliance plan, and a budget workbook are both called grant writing. They are not remotely the same job, and no honest single price covers both.
So let us take it apart.
The three ways grant writers charge
Hourly
Best when the scope is genuinely unclear or the work is advisory. Reviewing a draft your staff wrote, building a funder pipeline, sitting in on a strategy session, cleaning up a narrative library.
The risk is that you are buying an unbounded commitment. If you go hourly, ask for an estimate with a not-to-exceed number attached, and ask what happens when the estimate is wrong. A professional will have an answer ready.
Flat fee per proposal
The most common structure for a defined application, and usually the right one for an organization hiring outside help for the first time. You know the number before you start, and the risk of the work running long sits with the writer rather than with you.
What matters is what the flat fee includes. Ask specifically whether it covers the budget, the attachments, the portal submission, and any revisions the funder requests after review. Those four items are where flat-fee scopes quietly differ, and they are the difference between a price that looks low and a price that is low.
Monthly retainer
Right when you have a pipeline rather than a deadline. Several applications a year, renewals to maintain, reporting obligations running in the background, and a need for someone who knows your organization well enough that you are not re-explaining your programs every cycle.
A retainer is the more economical structure once your volume passes roughly three or four applications a year, and it is a waste of money below that. It also buys something a per-proposal arrangement does not, which is somebody paid to tell you not to apply for things.
What actually moves your number
Seven factors, roughly in order of how much they matter. These are why quotes for the same-sounding project can differ by a multiple.
- Funder type. Federal and government contract applications are the most expensive by a wide margin. State programs sit below them. County and regional funders below that. Private foundations are usually the least expensive, though a large national foundation with a competitive process can rival a state program.
- Whether your program data exists. This is the single biggest swing factor and almost nobody asks about it up front. If your outcomes are tracked and current, the writing is fast. If somebody has to reconstruct three years of numbers from spreadsheets and memory before a sentence can be written, that is a different engagement with a different price.
- Whether your financials are current. Most funders want a recent audit or 990 and a board-approved budget. If those are late or missing, that becomes part of the project timeline whether or not it is part of the scope.
- First application versus renewal. The first application to any funder is the expensive one. You are building the narrative, the budget structure, and the logic model from scratch. The renewal reuses most of it. If someone quotes you the same price for both, ask why.
- Match and compliance requirements. A match requirement means somebody has to document where the match comes from and prove it later. A compliance plan means additional narrative sections most people underestimate. Both add real hours.
- Portal complexity. Unglamorous and genuinely costly. Some federal and state portals require registrations that take weeks to clear, have their own formatting rules, and reject submissions for reasons the instructions never mention. Someone has to absorb that, and it is not fast the first time.
- Whether reporting is included. The largest line item people forget. Ask about it during pricing, not after the award.
The cost nobody quotes you
Your staff's time is usually the biggest expense in the whole arrangement, and it never appears on an invoice.
A serious application needs your program director for a couple of hours, your finance person for the budget and the attachments, and your executive director for review and signature. If your team is already at capacity, that time comes out of program delivery. It is a real cost and it belongs in your decision.
This is also why the "almost none of your time" pitch should worry you rather than reassure you. An application written without your data is an application written from a template, and reviewers read a lot of those.
The cheapest grant writer is the one who tells you which opportunities not to pursue.
Most organizations lose more money to chasing the wrong funding than to paying too much for the right help. A $75,000 award that requires a match you cannot raise, reporting your systems cannot produce, and staff you do not have is a net loss even when you win it. Somebody has to be willing to say that out loud before the work starts.
What you should not pay
A percentage of the award. Not because it sounds expensive, but because it is prohibited under the ethical codes of the profession, federal cost principles generally will not let you charge it to the award anyway, and the incentive runs backwards. A commission rewards volume of submissions rather than fit, and volume of submissions is exactly what drains your staff. I covered the rest of the warning signs in how to find and vet a grant writer.
Why I do not publish a rate
Since this page would be the natural place for it, the honest reason.
I price to the work required, and the work required varies enormously between organizations that look identical from the outside. Two nonprofits with the same budget, the same size, and the same program can be three times apart in effort depending on whether their outcomes are tracked, whether their financials are current, and whether they have ever administered a government award before. Publishing a single figure would mean overcharging one of them and underquoting the other, and I would rather have a fifteen-minute conversation and give you a number that is actually right.
What I will tell you plainly is the shape of it. My grant engagements run as part-time or full-time monthly retainers, priced against the scope and the fiscal size of the organization, and I will give you the number on the first call rather than after a discovery process.
The cheapest thing you can do before hiring anyone
Get your own house in order first, because it lowers every quote you will receive.
Pull your last three years of program outcomes into one document, with real numbers and the population served. Make sure your most recent 990 or audit and your board-approved budget are current and findable. Write down, in one paragraph each, what your three main programs actually do.
That material is the raw input for every application you will ever submit. Organizations that have it get faster, cheaper, and better applications from whoever they hire, including from their own staff. Organizations that do not have it pay someone else to build it, at consulting rates, on a deadline.
Where that leaves you
Buy the smallest thing that answers your question. One named opportunity, or one paid consultation that tells you which funders are worth your time. If the work is good, expand it. If it is not, you spent one application finding out instead of a year.
Common questions
How much does it cost to hire a grant writer?
There is no single answer because the work is not a single thing. You will generally see hourly rates quoted in a range that starts near what a skilled contractor charges and rises steeply for federal and government contract experience. Flat fees run from a few hundred dollars for a short letter of inquiry to several thousand for a complex multi-year federal application. Monthly retainers are common for organizations maintaining an ongoing pipeline. What matters more than the rate is the scope attached to it, because two quotes with the same number can describe very different amounts of work.
Can a small nonprofit on a tight budget afford a grant writer?
Often yes, if you buy the right thing. The mistake small organizations make is buying a retainer when they need one application, or buying an application when what they actually need is two hours of strategy telling them which three funders to pursue and which twelve to ignore. Start with a single named opportunity or a paid consultation. Both are small, bounded purchases, and both tell you whether the relationship is worth expanding before you commit to a year of it.
Is it cheaper to train our own staff than to hire a grant writer?
Cheaper in cash, more expensive in time, and it depends entirely on volume. Training makes sense if you have a steady pipeline, someone on staff with the time and the temperament for it, and mostly foundation-level applications. It makes much less sense for a first federal application, where the compliance and budget requirements are unforgiving and the learning curve is expensive to climb on a live deadline. Many organizations end up doing both: staff handle recurring renewals and smaller asks, an outside professional handles the large or unfamiliar ones.
Can I pay a grant writer out of the grant itself?
Sometimes for the administration of an awarded grant, rarely for the writing of the application. Federal cost principles generally treat organized fundraising costs as unallowable, and the work of preparing an application is usually classified that way. Grant management and reporting after the award is a different category and can often be budgeted, either directly or through your indirect rate. Read the specific funder's rules rather than assuming, and ask the question before you build the budget rather than after.
Do I still pay if the grant is not funded?
Yes, and you should be suspicious of anyone who says otherwise. You are paying for the work of preparing and submitting a competitive application, which happens regardless of the outcome. Nobody controls the funder's decision. A grant writer who only gets paid on wins has a strong incentive to submit a high volume of applications and a weak incentive to tell you when an opportunity is a bad fit, which is the opposite of what you want.
