Grant Budget FAQ: 12 Questions About Building Proposal Budgets That Get Approved

Three specific budget failures that cost organizations awards and create post-award compliance problems: submitting a budget with 22% indirect costs to a funder whose program guidelines cap indirect at 10%; writing a multi-year budget where year two and year three are identical to year one, signaling the applicant did not model actual implementation; and treating cost share as optional documentation after the award arrives, rather than a binding commitment with its own tracking requirements. These 12 questions address each of those failure points.

What should a grant proposal budget include?

A grant proposal budget should include every cost required to carry out the proposed project — nothing more, nothing less. Standard line item categories: personnel (wages and salaries for each position charged to the grant, expressed as FTE or percentage of time), fringe benefits, direct program costs (materials, supplies, participant costs, travel, printing, equipment), contracted services (consultants, subcontractors, evaluators), and indirect costs.

Avoid padding: reviewers scrutinize budgets for costs that appear inflated or unrelated to project activities. Avoid under-budgeting: a budget that cannot realistically fund the described activities signals the applicant has not thought through implementation.

What is a budget narrative and how detailed should it be?

A budget narrative explains every line in the budget — what each item is, why it is necessary, and how the dollar amount was calculated. The calculation should be shown explicitly: “Program Coordinator (1.0 FTE x $52,000 annual salary = $52,000)” not “Program Coordinator: $52,000.”

Every line item needs this treatment, including indirect costs, fringe, and travel. When in doubt, provide more detail rather than less. A reviewer who cannot tell how you calculated a line item will either score the budget section low or send a budget revision request.

How do I calculate indirect costs in a proposal budget?

Indirect costs represent overhead expenses that cannot be directly attributed to a single project — rent, utilities, general administrative staff time, accounting, IT. Three approaches: if your organization has a federally negotiated indirect cost rate agreement (NICRA), use that rate. If you do not have a NICRA, the de minimis rate under 2 CFR 200.414(f) allows nonprofits to use 10% of modified total direct costs on federal awards. For foundation grants, check the funder’s guidelines — many cap indirect at 10–15%.

Apply indirect costs to the MTDC base, which excludes equipment over $5,000 and subaward amounts above $25,000.

Can I include staff time in a grant budget?

Yes — personnel costs are the largest category in most nonprofit grant budgets. Every staff position that will contribute effort to the project should be in the budget at the correct percentage of time. If your program director will spend 50% of their time on the project, budget 50% of their salary and 50% of their fringe benefits.

What you cannot do: include 100% of a position’s time in a grant budget while that person also works on other organizational activities. Federal auditors specifically examine whether personnel charged to grants actually worked the hours charged, verified through time-and-effort documentation.

What is fringe benefits and how do I budget it?

Fringe benefits are the employer-side costs of employment beyond base wages: FICA (7.65% of wages), federal and state unemployment insurance, workers’ compensation insurance, health and dental insurance premiums, and retirement contributions. In a grant budget, fringe is calculated as a percentage of the wages for each position charged to the grant.

A common nonprofit fringe rate runs 20–30% of wages. Show the rate explicitly: “Fringe Benefits: $52,000 x 25% = $13,000.” A budget that includes wages but no fringe tells reviewers either that the organization does not offer benefits or that the budget is incomplete.

How do I budget for a multi-year grant?

Multi-year grant budgets should reflect actual projected costs for each year, not copies of year one repeated. Year one typically includes startup costs — staff recruitment time, equipment purchase, partner onboarding — that do not recur. Years two and three should reflect salary escalation (apply your standard annual merit increase rate, typically 3–5%), any phase-in of additional staff positions, and changes in program scale.

A year two budget identical to year one signals the applicant did not model actual implementation. Also account for fringe benefit rate changes (health insurance premiums increase annually) and evaluation costs that vary by project phase.

What is cost share and when is it required?

Cost share (also called matching funds) is the portion of a project’s total cost that the applicant commits to covering from non-federal sources. Some federal grant programs require mandatory cost share — a specific percentage of the project budget that must come from organizational resources, state funds, or private donors.

Once committed in the application, cost share creates a binding obligation: if you commit to $50,000 in cost share, you must produce documentation showing $50,000 was actually spent on the project from non-grant sources. The most common cost share mistake: treating it as a negotiating chip in the proposal with no system to track and document the actual contributions after award.

Can the grant budget change after the award?

Yes, within defined limits. Most grant agreements allow reallocation between budget categories up to a threshold — commonly 10–15% of the total award — without prior funder approval. Reallocations above that threshold require a written budget modification request approved by the funder before the expenditure occurs, not after.

For federal grants, significant changes to scope, key personnel, or budget typically require prior approval from the awarding agency. Read the prior approval requirements in your award agreement when you receive the award, not when you need to make a change.

What makes a budget raise red flags for reviewers?

Six items that trigger scrutiny: indirect costs above the funder’s stated cap without a negotiated rate justification; no fringe benefits on personnel lines; equipment purchases above $5,000 not listed as allowable capital expenditures in the program guidelines; consultant rates above $150/hour without explicit qualification justification; a cost-per-participant figure inconsistent with similar programs; and a budget total that does not match the stated award ceiling in the RFP.

How do I show in-kind contributions in the budget?

In-kind contributions are non-cash resources contributed to the project — volunteer time, donated space, donated equipment. Show them as a separate column labeled “In-Kind” with dollar values at fair market rate: volunteer time at the comparable wage for that work type, donated space at the comparable rental rate, donated equipment at fair market value.

In-kind committed as cost share must be documented the same way as cash cost share — signed time sheets, letters confirming fair market value, or equipment valuations. In-kind listed in the proposal but not documented after award creates the same audit exposure as undocumented cash cost share.

What is program income and how does it affect the budget?

Program income is revenue generated by the project using grant-funded resources — participant fees, service fees, ticket sales. Federal grants under 2 CFR 200.307 require grantees to either add program income to the project budget, use it to offset project costs, or remit it to the federal agency — which treatment applies depends on the award terms.

Program income must be separately tracked and reported; it cannot be deposited into the general operating fund and treated as unrestricted revenue. If your project will generate any participant fees, note the anticipated program income in the budget and address how it will be treated.

How do I build a budget for a subaward?

A subaward is an award from the primary grantee to a subrecipient organization that will carry out a portion of the project. The budget for a subaward should be built by the subrecipient and submitted as a separate budget with its own personnel, direct costs, fringe, and indirect line items. The primary grantee is responsible for monitoring the subrecipient’s performance and financial compliance.

When the primary grantee applies to the funder, the subaward amount appears as a single line in the direct costs section. The first $25,000 of each subaward is included in the MTDC base for indirect cost purposes; amounts above $25,000 per subaward are excluded.
