This calculator returns an industry range, not a Grant Writing Service quote. It combines two well-documented pricing patterns: the type of grant you are pursuing and the complexity of the work involved. Foundation grants sit at the lower end because they are shorter, while federal grants sit at the higher end because they demand more sections, more compliance, and more hours. SBIR and STTR research proposals are the most involved, since they require Specific Aims and a commercialization plan.
Add-ons move the estimate too. Prospect research to identify aligned funders, a standalone budget narrative, and help with program or logic-model design each add hours. The output reflects what credentialed grant writers across the market typically charge, based on industry data reported by sources like the Grant Professionals Association and Instrumentl (2026).
The number behind every estimate is hours. A short foundation grant typically takes a writer roughly 20 to 40 hours, while a competitive federal grant can exceed 60 hours once the compliance forms, multiple narrative sections, and a detailed budget narrative are accounted for. An SBIR or STTR proposal usually runs higher still, because the Specific Aims and commercialization plan demand specialized work. Multiply those hours by a typical hourly rate of about $50 to $150 and you arrive at the flat-fee ranges this tool reports.
Read the output as a planning figure, not a binding price. The estimate does not include a paid funder database subscription, agency registration time in systems such as SAM.gov or eRA Commons, or printing and courier costs on the rare application that still requires them. A long-term retainer for an ongoing pipeline is priced differently again. Treat the number as a starting point for budgeting, then confirm the exact scope when you request a real quote.
A few principles to keep in mind as you read your estimate. Ethical writers price on a flat fee or hourly basis and never take a percentage of your award. The more grant-ready your materials already are, the lower your cost, because the writer spends less time building from scratch.

Frequently asked questions
How is grant writing priced?+
Grant writing is usually priced as a flat fee per proposal or an hourly rate. Flat fees commonly range from about $1,500 for a short foundation request to $6,000 or more for a complex federal application. Ethical writers never charge a percentage of the award.
Why do federal grants cost more?+
Federal grants cost more because they take far more hours. They require detailed compliance forms, multiple narrative sections, a thorough budget narrative, and submission through Grants.gov, which together can push the work past 60 hours.
