Grant Writing Cost Calculator

The grant writing cost calculator above estimates what a grant writer would typically charge for one application, as a market range rather than a quote. Choose the type of grant, the complexity, and any add-ons, and it returns a low and high figure. These are general market ranges, not our prices.

How the estimate is calculated

The calculator starts from a base range for each type of grant:

Grant type	Base range
Foundation grant	$1,500 to $4,000
Federal grant	$3,500 to $8,000
SBIR or STTR research proposal	$5,000 to $12,000

It then multiplies both ends by the complexity you choose: 0.8 for simple, 1.0 for standard, and 1.4 for complex. Add-ons are added on top of the result: prospect research ($500 to $2,000), program design ($1,000 to $3,000), and a budget with narrative ($400 to $1,200). A complex federal application with prospect research, for example, comes to $5,400 to $13,200.

Why the ranges sit where they do

The ranges are consistent with published market figures. Instrumentl reports grant writing fees of about $1,000 to $8,000 or more per proposal and hourly rates of about $50 to $150, and Funding for Good reports hourly rates from $25 to $250 depending on experience. The spread between grant types reflects hours. A foundation request is often a few pages or an online form. A federal application adds a longer narrative scored against published criteria, the SF-424 forms, a detailed budget justification, and registration requirements. An SBIR or STTR proposal adds a research plan, specific aims, and a commercialization plan, which is why it sits at the top.

The estimate does not include costs outside the writing: paid grant database subscriptions, staff time to gather documents, or time spent completing agency registrations. It also assumes one application; ongoing work across many deadlines is usually priced as a retainer.

What moves a real quote up or down

• What already exists. A writer who can start from a current program description, budget, and outcome data needs fewer hours than one who must build them.
• How fast the deadline is. Compressed timelines cost more or limit who can take the work.
• How much research the application needs. Needs data, funder research, and a literature review all add hours.
• Commission is a red flag. The Grant Professionals Association's code of ethics bars members from accepting compensation based on a percentage of grant funds. Our article on whether grant writers work on commission explains why.
