How to Allocate Expenses Across Multiple Grants

When multiple awards benefit from one cost, allocation is a documented accounting judgment—not a way to use available budgets. Federal rules apply only to federal awards (including applicable pass-through awards); other grants follow their agreements and the organization's consistently applied GAAP policies.

This guide covers the methods, math, and best practices.

Why Allocation Matters

Compliance Reasons

• Federal awards require costs to be allowable, reasonable, allocable, and consistently treated under 2 CFR 200.403–200.405
• Costs must be allocated consistently
• Auditors will test your methodology
• Incorrect allocation = audit findings

Practical Reasons

• Accurate grant budgets
• Fair reporting to funders
• Avoid overcharging one grant
• Show the true cost of each activity without chasing available budget

Types of Costs

Direct Costs

Costs that can be identified specifically with a particular grant.

Examples:

• Salary of a person working 100% on one grant
• Supplies purchased specifically for one program
• Travel for a specific grant activity

Allocation: Charge directly to the single grant (no allocation needed)

Shared Direct Costs

Costs that directly benefit multiple grants and must be allocated.

Examples:

• Salary of a person working on multiple grants
• Supplies used by multiple programs
• Shared equipment used by different projects

Allocation: Must be split among benefiting grants

Indirect Costs (F&A)

Overhead costs that benefit all activities.

Examples:

• Rent
• Utilities
• Executive salaries
• IT infrastructure

Allocation: Treat consistently as direct or indirect under the organization's policy. For a federal award, use the applicable negotiated or permitted indirect-cost rate and its specified base; do not assume MTDC applies to every award.

Allocation Methods

Method 1: Time-Based (Best for Personnel)

Allocate based on actual time spent on each grant.

How it works:

1. Staff track time spent on each grant
2. Calculate percentage of time per grant
3. Allocate salary proportionally

Illustrative example: Employee salary: $60,000/year

• Grant A: 50% time = $30,000
• Grant B: 30% time = $18,000
• Grant C: 20% time = $12,000

Documentation: Federal payroll charges must be based on records that accurately reflect work performed, are supported by the internal-control system, and cover all compensated activity under 2 CFR 200.430. The rule does not universally prescribe timesheets, signatures, or semiannual certifications. Use records appropriate to the entity and award; budget estimates alone generally require timely adjustment when actual work differs significantly.

Method 2: Percentage-Based (Common for Shared Costs)

Allocate using a predetermined percentage based on a reasonable basis.

Common bases:

• Direct labor hours or costs
• Direct costs
• Square footage (for space costs)
• Headcount
• Units of service

Illustrative example: Allocating Shared Supplies by Direct Labor Cost Total supplies: $10,000

• Grant A direct labor: $100,000 (50%)
• Grant B direct labor: $60,000 (30%)
• Grant C direct labor: $40,000 (20%)

Allocation:

• Grant A: $10,000 × 50% = $5,000
• Grant B: $10,000 × 30% = $3,000
• Grant C: $10,000 × 20% = $2,000

Method 3: Usage-Based (When Measurable)

Allocate based on actual usage metrics.

Illustrative example: Printing Costs by Pages Printed Total printing: $1,000

• Grant A: 600 pages (60%)
• Grant B: 400 pages (40%)

Allocation:

• Grant A: $600
• Grant B: $400

Works well for:

• Mileage (by trip destination)
• Printing (by project)
• Phone (by call logs)
• Postage (by project mailings)

Method 4: Headcount or FTE-Based

Allocate based on number of staff per grant.

Illustrative example: Office Supplies Total supplies: $5,000 Staff:

• Grant A: 3 FTEs
• Grant B: 2 FTEs

Allocation:

• Grant A: $5,000 × (3/5) = $3,000
• Grant B: $5,000 × (2/5) = $2,000

Method 5: Square Footage (For Space)

Allocate space costs by area used.

Illustrative example: Rent Allocation Total rent: $10,000/month Space usage:

• Grant A program area: 1,000 sq ft (40%)
• Grant B program area: 750 sq ft (30%)
• Shared/admin: 750 sq ft (30%)

Allocation (program portion):

• Grant A: $4,000
• Grant B: $3,000
• Admin/indirect: $3,000

Building an Allocation Plan

Step 1: Identify Shared Costs

List all costs that benefit multiple grants:

• Personnel (partial effort)
• Shared supplies
• Shared equipment
• Shared space
• Travel benefiting multiple grants

Step 2: Choose Allocation Bases

For each shared cost type, select a reasonable basis:

Cost Type	Recommended Basis
Personnel	Time worked
Supplies	Direct costs or headcount
Equipment	Usage hours or direct costs
Space	Square footage
Travel	Direct identification when possible

Step 3: Document Your Methodology

Write down:

• What costs are allocated
• What basis is used for each
• How calculations are performed
• When allocations are recorded under the organization's close and reporting cadence

Step 4: Apply Consistently

Apply like methods in like circumstances. A different basis can be appropriate when the benefit relationship differs, but document why. Never allocate based on a grant's remaining budget or shift a cost to overcome a funding deficiency or avoid award restrictions.

Compliance Requirements

Federal Grants (Uniform Guidance)

2 CFR 200.405 requires that costs be allocable if they:

1. Are incurred specifically for the award
2. Benefit both the award and other work and can be distributed reasonably
3. Are necessary to the overall operation and assignable to the award per allocation principles

Key principles:

• Allocation must be based on benefits received
• Must be consistently applied
• Must be supported by documentation
• Cannot shift costs to avoid deficits

Common Compliance Issues

Issue 1: Inconsistent Methods Using different allocation methods for similar costs.

Fix: Document and follow a consistent methodology.

Issue 2: Missing Time Documentation Allocating personnel costs without time records.

Fix: Implement records and controls that accurately support work performed and payroll distribution. Timesheets may be appropriate, but no single format is universally required.

Issue 3: Budget-Based Allocation Allocating based on available budget rather than actual benefit.

Fix: Allocate based on benefit, not budget availability.

Issue 4: Retroactive Changes Changing allocation percentages to meet budget targets.

Fix: Never change allocations merely to use a budget. Correct genuine prior-period errors with contemporaneous support, approval, and an audit trail; apply revised estimates prospectively when facts—not prior errors—have changed.

Time Tracking for Personnel

Personnel is usually the largest allocation challenge.

Requirements

Use records that accurately reflect the work performed and reconcile interim estimates to actual activity when required. Timesheets, activity logs, payroll distributions, or integrated systems may be suitable depending on the facts; no one format is universally mandated. Follow stricter award terms or organizational policy when they apply.

What Auditors Look For

• Records incorporated into the organization's official system
• Evidence that required review controls operated
• Coverage of all compensated activity and applicable cost objectives
• Timely, supported adjustments when interim estimates differ materially from actual activity

Common Scenarios

Scenario 1: Staff on Multiple Grants

An employee works on three grants and administration.

Solution:

• Track time weekly
• Allocate salary/benefits based on actual time
• Reconcile and adjust on the organization's documented cadence
• Document changes in effort

Scenario 2: Shared Program Supplies

Supplies used by participants in multiple programs.

Solution:

• Track by program when practical
• Otherwise, allocate by participant count or direct costs
• Document the basis chosen

Scenario 3: Conference Attendance

Staff attends conference relevant to multiple grants.

Solution:

• Allocate registration based on time spent on each topic
• Or split evenly if broadly applicable
• Document rationale

Scenario 4: Shared Equipment Purchase

Equipment used by staff across multiple grants.

Solution:

• Determine whether the item meets the applicable equipment definition and whether award approval, property, or disposition rules apply
• For smaller items, allocate by user time or direct costs
• Track usage if practical

Avoiding Audit Findings

1. Document everything — Methodology, calculations, approvals
2. Be consistent — Same method for same cost types
3. Be reasonable — Allocations should make intuitive sense
4. Review when facts change and on a documented cadence — No universal federal quarterly review rule applies
5. Correct errors properly — Supported cost transfers may correct prior periods; never rewrite history merely to fix budgets
6. Get it in writing — Document any funder-approved exceptions

Tools for Allocation

Manual Tracking

• Spreadsheets for allocation calculations
• Timesheets for personnel
• Monthly reconciliation

Automated Tools

• Grant management software with allocation features
• Time tracking systems
• Accounting system allocation modules

Internal system-selection considerations

Use software that:

• Tracks time by grant
• Calculates allocations automatically
• Maintains audit trail
• Integrates with accounting system

How GrantLink supports this today

Add a grant manually or upload its grant documents, then link Expenses and Money received for that grant to the relevant QuickBooks activity. Expense links backfill and auto-allocate eligible linked activity. Use the Ledger, Todos, or manual allocation for exceptions and shared-cost review.

QuickBooks Online remains the accounting source of truth. GrantLink allocations do not inherently rewrite QuickBooks Online; any accounting write requires explicit permission and the applicable workflow.
