Master federal grant budgeting with the Allowable-Allocable-Reasonable framework. Learn direct vs. indirect costs, personnel calculations, fringe rates, and the compliance fundamentals that prevent audit findings.

Grant Budgeting Fundamentals: Federal Cost Principles and Compliant Budgets

Budget sections reveal organizational sophistication—or expose lack of it. Reviewers can immediately spot budgets built by professionals versus those assembled without understanding of federal cost principles and compliance requirements.

For nonprofit organizations seeking federal funding, mastering grant budgeting isn't optional. Budget errors cause immediate rejections, audit findings during implementation, and fund recovery requirements that can destabilize organizations.

The Allowable-Allocable-Reasonable Framework

All federal grant spending must pass three tests. This framework governs every cost you include in your budget.

Allowable

Costs must be allowable under:

The specific grant program's regulations
Your organization's policies
Federal cost principles (2 CFR 200 for most nonprofits)

Commonly unallowable costs:

Alcohol
Entertainment
Lobbying
General fundraising
Bad debts
Fines and penalties
Contingency reserves

Example: Even if your organization routinely serves wine at board meetings, alcohol costs cannot be charged to federal grants—ever.

Allocable

Costs must benefit the specific grant program:

The cost provides direct benefit to the funded project
The allocation method is reasonable and documented
Costs aren't charged to multiple sources for the same thing

Example: If a staff member works on three different grants, their salary must be allocated to each grant based on actual effort—not convenience.

Reasonable

Costs must reflect prudent decision-making:

Necessary for program operation
Not excessive compared to market rates
What a reasonable person would pay in similar circumstances

Example: Business class airfare when coach is available is typically unreasonable. First class is almost never reasonable.

Direct Costs vs. Indirect Costs

Understanding this distinction is fundamental to federal budgeting.

Direct Costs

Direct costs are specifically identifiable to the grant project:

Personnel: Staff working on the project
Fringe benefits: For project staff
Travel: For project purposes
Equipment: Items used for the project
Supplies: Materials consumed by the project
Contractual: Services procured for the project
Other: Costs specific to the project

Direct costs are itemized in the budget and charged to the grant based on actual expenditure or allocation.

Indirect Costs (Facilities & Administrative)

Indirect costs support operations generally and can't be traced to specific projects:

Building occupancy (rent, utilities, maintenance)
General administration
Accounting and finance
Human resources
Information technology
Depreciation

Indirect costs are charged as a rate (percentage) applied to a base (typically direct costs or modified total direct costs).

Negotiated Indirect Cost Rates

Organizations with federal funding history may negotiate an indirect cost rate with a cognizant agency:

Calculated rate: Based on actual indirect costs divided by direct cost base
Negotiated rate: Agreed upon with federal cognizant agency
De minimis rate: 10% of modified total direct costs (available to organizations without negotiated rates)

Example budget line:

Indirect Costs (10% de minimis rate on MTDC): $150,000 x 10% = $15,000

Personnel Cost Calculations

Personnel is typically the largest budget category. Getting it right matters.

Salary Calculations

Calculate annual salary charged to the grant:

Annual Salary × % of Time on Project = Grant Salary
$65,000 × 50% = $32,500

FTE (Full-Time Equivalent)

Express effort consistently using FTE:

| Expression | Meaning | |------------|---------| | 1.0 FTE | Full-time (100% on project) | | 0.5 FTE | Half-time (50% on project) | | 0.25 FTE | Quarter-time (25% on project) |

Multi-Year Salary Projections

Include appropriate salary increases for multi-year projects:

Research typical annual increases (2-4% is common)
Apply increases starting Year 2
Document assumptions in budget narrative

Example: | Year | Base Salary | % Effort | Amount | |------|-------------|----------|--------| | Year 1 | $65,000 | 50% | $32,500 | | Year 2 | $66,950 | 50% | $33,475 | | Year 3 | $68,959 | 50% | $34,480 |

Fringe Benefits

Fringe benefits are the employer's cost beyond salary:

Common fringe components:

FICA (Social Security and Medicare): 7.65%
Health insurance
Retirement contributions
Workers' compensation
Unemployment insurance
Life/disability insurance

Calculating fringe rate:

Total Annual Fringe Costs / Total Annual Salaries = Fringe Rate
$850,000 / $2,500,000 = 34%

Organizations typically have one composite fringe rate, though some separate rates for different employee classes.

Equipment vs. Supplies

Federal grants distinguish equipment from supplies based on value threshold.

Equipment (Typically $5,000+)

Unit acquisition cost of $5,000 or more
Useful life exceeding one year
Tangible personal property
Subject to inventory and tracking requirements

Examples: Computers, vehicles, specialized machinery, scientific instruments

Supplies (Under $5,000)

Unit cost under the equipment threshold
Consumed in program operation
May include smaller technology items

Examples: Office supplies, educational materials, laptops under threshold

Budget tip: Check the specific program's equipment threshold—some grants use different amounts.

Travel Budgeting

Travel costs must follow federal guidelines (or your organization's policies if more restrictive).

Allowable Travel Costs

Transportation (airfare, mileage, rental car)
Lodging
Per diem (meals and incidental expenses)
Registration fees for conferences

Federal Per Diem Rates

Federal grants typically require use of GSA per diem rates:

Lodging: Actual cost up to GSA maximum
Meals & Incidental Expenses (M&IE): Fixed daily rate by location
Check GSA.gov for current rates

Budget calculation example:

3 staff × 2 nights × $186/night lodging = $1,116 3 staff × 3 days × $59 M&IE = $531 3 staff × roundtrip airfare @ $400 = $1,200 Total conference travel: $2,847

Budget Narrative Requirements

The budget narrative explains and justifies each line item.

What to Include

Personnel:

Name (if known) or TBD with qualifications
Role on the project
Percentage of time/FTE
Salary basis (annual rate)
Calculation showing how you arrived at the amount

Other categories:

What the item is
Why it's necessary
How you determined the amount
How it benefits the project

Budget Narrative Example

Program Coordinator (1.0 FTE) - $52,000 The Program Coordinator (TBD) will manage day-to-day program operations, coordinate with partner agencies, supervise peer educators, and maintain participant records. The salary is based on our organization's pay scale for this position level and is consistent with regional rates for similar positions. The position is 100% dedicated to this project.

Fringe Benefits - $17,680 (34%) Fringe benefits include FICA (7.65%), health insurance ($650/month), retirement contribution (6% of salary), workers' compensation (1.2%), and unemployment insurance (2.5%). The composite rate of 34% is consistent with our audited financial statements.

Common Budgeting Mistakes

Mistake 1: Math Errors

Triple-check all calculations. Reviewers notice when numbers don't add up.

Mistake 2: Unrealistic Estimates

Budgets that are obviously too low suggest inexperience. Get real quotes.

Mistake 3: Missing Items

Forgetting necessary costs (fringe benefits, indirect costs, evaluation) creates implementation problems.

Mistake 4: Exceeding Limits

Many grants cap certain costs (e.g., equipment at 10% of budget). Know and follow limits.

Mistake 5: Inadequate Justification

Every line item needs explanation. "Supplies - $5,000" without narrative fails.

Mistake 6: Inconsistency with Narrative

Budget and program narrative must align. If you describe three staff, budget three staff.
