Introduction

Federal grant rejections rarely cite the program plan as the problem. They cite the budget. A 2023 analysis of NIH reviewer comments found that budget-related issues, including unjustified costs, incorrect indirect cost calculations, and non-compliant cost allocations, were cited in 34% of unfunded applications. The non-profit sector loses millions in recoverable overhead annually because finance teams apply the wrong indirect cost base, exclude expenses from Modified Total Direct Costs that should be included, or simply default to the 10% de minimis rate when a negotiated rate of 22% would be fully justified and allowable. The OMB Uniform Guidance (2 CFR 200), which governs all federal grant budgets, is 150 pages of specific cost allowability rules that most grant writers learn piecemeal. One calculation error in a federal grant budget is not just a lost award. It is a compliance violation that can trigger an audit.

What This Calculator Does

This grant budget calculator helps non-profit organizations allocate direct and indirect costs for federal, state, and foundation grant proposals in compliance with the 2026 OMB Uniform Guidance (2 CFR 200). It calculates Modified Total Direct Costs (MTDC), applies your indirect cost rate (the 10% de minimis or your negotiated NICRA rate), handles all MTDC exclusions (equipment over $5,000, subaward amounts over $25,000, participant support costs), and calculates cost share and match requirements. The output is a compliant budget summary ready for proposal submission.

The Formula

MTDC = Total Direct Costs - Excluded Items (equipment >$5K, subawards >$25K, participant support) | Indirect Costs = MTDC x Indirect Cost Rate | Total Budget = Total Direct Costs + Indirect Costs

Direct costs are expenses specifically identifiable to the grant project: personnel salaries, fringe benefits, travel, equipment, supplies, contractual services, and other direct costs. The MTDC base excludes certain cost categories per 2 CFR 200.1 before applying the indirect rate: equipment costing $5,000 or more per unit, the portion of each subaward exceeding $25,000 (the first $25,000 is included), participant support costs, and capital expenditures. Indirect costs recover shared organizational overhead: rent, utilities, accounting, IT, and executive management proportional to the project's use of those resources. The total budget equals all direct costs plus indirect costs calculated on the MTDC base.

Step-by-Step Example

1

Enter personnel and fringe benefit costs

Program Director: $72,000 salary x 50% FTE = $36,000. Program Coordinator: $48,000 x 75% = $36,000. Total personnel: $72,000. Fringe benefits at 32% (health insurance $8,500, retirement 5%, FICA 7.65%, workers comp 1.5%): $23,040. Total personnel and fringe: $95,040.

2

Enter all other direct cost categories

Travel: $6,500 (conferences, site visits). Equipment: $12,000 (laptop $1,200 + projector $800 + $10,000 document scanner). Supplies: $8,400. Consultants: $22,000 (evaluation firm). Subaward to partner: $40,000. Other: $4,000. Total direct costs: $187,940.

3

Calculate MTDC base and indirect costs

MTDC exclusions: Equipment over $5,000 = $10,000 (scanner only; laptop $1,200 and projector $800 are under $5K, so included). Subaward over $25,000 = $15,000 (only the amount above $25K is excluded). Total excluded: $25,000. MTDC base: $187,940 - $25,000 = $162,940. Indirect at 10% de minimis: $16,294. Total budget: $187,940 + $16,294 = $204,234.

4

Calculate cost share if required

Funder requires 25% match. Total project cost: $204,234. Match requirement: $204,234 x 25% / 125% = $40,847. Grant request: $163,387. Verify match sources: in-kind volunteer time ($18,000), unrestricted organizational contribution ($22,847). Total match: $40,847. Cost share documented and ready for budget narrative.

Real-World Use Cases

Grant Writer Building a First Federal Application

A development director writing the organization's first federal grant application must navigate indirect cost rates for the first time. The calculator clarifies that the 10% de minimis rate applies to MTDC, not total direct costs, and that certain items must be excluded before applying the rate. On a $200,000 budget with $30,000 in exclusions, the difference between applying 10% to $200,000 versus $170,000 is $3,000 in incorrectly claimed overhead that an auditor would require the organization to return.

CFO Evaluating Whether to Negotiate a NICRA

A mid-sized nonprofit receives $1.2 million annually in federal grants. The true indirect cost rate, calculated by the finance team, is 23% of MTDC. Using the 10% de minimis instead of a negotiated NICRA leaves $156,000 in recoverable overhead unclaimed each year. The NICRA negotiation process takes 3 to 6 months but produces $156,000 in additional annual revenue. The CFO uses the grant budget calculator to model the difference and make the business case to leadership for pursuing a NICRA.

Development Director Comparing Multiple Grant Opportunities

Three foundation grants are available: one capping indirect at 10% of total project costs, one allowing 15% of MTDC, and one using the organization's full NICRA of 22%. The grant budget calculator models all three side by side, showing that the full NICRA grant recovers $7,000 more in overhead for the same program budget. This analysis helps prioritize limited staff proposal-writing time toward funders with the most favorable indirect cost policies.

Common Mistakes to Avoid

  • Applying the indirect cost rate to total direct costs instead of MTDC. The 10% de minimis and most NICRA rates apply to Modified Total Direct Costs, not total direct costs. On a $200,000 budget with $30,000 in MTDC exclusions, applying 10% to $200,000 overclaims $3,000 in indirect costs compared to the correct $17,000 on $170,000 MTDC.

  • Including the full subaward amount in MTDC. Only the first $25,000 of each subaward is included in the MTDC base. A $60,000 subaward contributes only $25,000 to the MTDC calculation. Including the full $60,000 overstates indirect costs and creates an audit finding.

  • Not budgeting fringe benefits as a separate direct cost line. Fringe benefits (FICA, health insurance, retirement, unemployment insurance) are direct costs on federal grants, not indirect costs. They must be calculated at the organization's actual fringe rate, documented in a written fringe benefit policy, and listed separately in the budget.

  • Not documenting cost share sources before submitting. If a grant requires 25% match, every dollar of cost share must be traceable to a specific source at the time of application. Volunteer time (valued at $36.15/hour per Independent Sector 2026 rate), in-kind goods, and unrestricted organizational contributions all require supporting documentation.

  • Submitting a budget without a detailed justification narrative. Every line item in a federal grant budget requires a brief explanation of how it was calculated and why it is necessary. Reviewers who cannot follow the logic of a budget deduct points. A well-written budget narrative adds credibility to the entire application.

Frequently Asked Questions

Accuracy and Disclaimer

This calculator provides grant budget estimates based on 2026 OMB Uniform Guidance (2 CFR 200) rules and general nonprofit accounting practices. Grant budget requirements vary by funder, federal agency, and specific funding opportunity announcement. Always review the solicitation requirements before finalizing your budget. MTDC exclusions, allowable costs, and indirect cost rate requirements may differ from the defaults in this calculator. Consult with your grants management office or a certified public accountant with nonprofit grant expertise before submitting federal grant budgets.

Conclusion

A correctly built grant budget does more than satisfy compliance requirements. It recovers the full overhead your organization is entitled to receive and prevents the audit findings that come from miscalculated indirect costs. Once your grant budget is finalized, use the Program Cost Per Beneficiary Calculator to confirm the per-person cost is competitive with funder benchmarks, and the Earned Income vs. Contributed Income Calculator to verify the grant fits into a diversified funding strategy that reduces single-source dependency.
