How To Calculate Indirect Cost

Calculate your organization’s indirect costs accurately with our comprehensive tool. Understand how overhead, administrative, and facility costs impact your total project expenses.

Comprehensive Guide: How to Calculate Indirect Costs

Indirect costs represent the expenses of doing business that are not readily identified with a particular grant, contract, project function, or activity, but are necessary for the general operation of the organization and the conduct of activities it performs. Proper calculation of indirect costs is essential for accurate budgeting, compliance with funding requirements, and financial sustainability.

Understanding Indirect Costs

Indirect costs, also known as overhead or facilities and administrative (F&A) costs, typically include:

• Administrative salaries and expenses
• Rent and utilities for facilities
• General office expenses
• Depreciation on buildings and equipment
• Library expenses
• Departmental administration expenses
• Sponsored projects administration expenses

These costs are real expenses that support the overall operations of an organization but cannot be directly attributed to specific projects or activities.

Why Indirect Cost Recovery Matters

Recovering indirect costs is crucial for several reasons:

1. Financial Sustainability: Helps cover the true cost of operating the organization
2. Compliance: Many funding agencies require proper allocation of indirect costs
3. Fairness: Ensures all projects contribute to shared organizational resources
4. Accuracy: Provides more realistic budgeting and financial planning

Typical Indirect Cost Rates by Organization Type

Organization Type	Typical Rate Range	Average Rate
Universities	40%-60%	52%
Nonprofit Organizations	10%-25%	18%
Small Businesses	20%-50%	35%
Government Contractors	30%-70%	48%

Methods for Calculating Indirect Costs

There are several approved methods for calculating indirect costs, each with its own application rules:

1. Modified Total Direct Cost (MTDC)

The most common method used by federal agencies. MTDC excludes:

• Equipment (>$5,000 and useful life >1 year)
• Capital expenditures
• Patient care costs
• Tuition remission
• Rental costs
• Subawards over $25,000

2. Total Direct Cost (TDC)

Applies the indirect cost rate to all direct costs without exclusions. Less common for federal awards but sometimes used by private foundations.

3. Salaries and Wages Only

Applies the indirect cost rate only to the salaries and wages portion of direct costs. Often used when other methods would result in insufficient recovery.

Step-by-Step Calculation Process

Follow these steps to calculate indirect costs accurately:

1. Identify Direct Costs: Sum all direct costs associated with the project
2. Determine Applicable Exclusions: Remove any costs excluded by your rate agreement
3. Calculate Adjusted Direct Cost Base: Subtract exclusions from total direct costs
4. Apply Indirect Cost Rate: Multiply the adjusted base by your negotiated rate
5. Calculate Total Project Cost: Add indirect costs to direct costs
6. Verify Compliance: Ensure your calculation follows funder requirements

Common Mistakes to Avoid

Many organizations make errors in indirect cost calculations that can lead to compliance issues or lost revenue:

• Using the wrong base: Applying the rate to the wrong direct cost components
• Incorrect exclusions: Failing to properly exclude required items from the base
• Outdated rates: Using expired negotiated rates
• Double-counting: Including costs in both direct and indirect categories
• Ignoring rate caps: Some funders limit indirect cost recovery percentages
• Poor documentation: Inadequate records to support calculations

Comparison of Federal Agency Indirect Cost Policies

Agency	Standard Rate	Rate Cap	Special Provisions
National Institutes of Health (NIH)	Negotiated	None for most	10% de minimis for new awardees
National Science Foundation (NSF)	Negotiated	None	Requires prior approval for changes
Department of Education	Negotiated	8% for training grants	MTDC base required
Department of Defense	Negotiated	Varies by contract	Separate rates for R&D and other work

Negotiating Indirect Cost Rates

Organizations must negotiate their indirect cost rates with the federal government through their cognizant agency. The process typically involves:

1. Submitting a formal indirect cost proposal
2. Providing detailed financial documentation
3. Justifying all cost allocations
4. Undergoing audit and review
5. Receiving a negotiated rate agreement

The Uniform Guidance (2 CFR 200) provides the federal regulations governing indirect cost recovery. Most federal agencies have adopted these standards.

Best Practices for Indirect Cost Management

To optimize indirect cost recovery and maintain compliance:

• Maintain accurate time and effort reporting systems
• Document all cost allocations thoroughly
• Train staff on proper cost accounting procedures
• Review rate agreements annually
• Monitor subrecipient indirect cost recovery
• Use consistent allocation methods across all projects
• Prepare for audits with complete documentation

For organizations new to indirect cost recovery, the National Cancer Institute’s Indirect Cost Guide provides an excellent introduction to the concepts and requirements.

Special Considerations for Different Organization Types

Universities and Colleges

Higher education institutions typically have:

• Higher indirect cost rates (often 40-60%)
• Complex rate structures with multiple components
• Separate rates for research, instruction, and other activities
• Special provisions for federal flow-through funds

Nonprofit Organizations

Nonprofits often face challenges with:

• Lower negotiated rates (typically 10-25%)
• Funders that limit or prohibit indirect cost recovery
• Need to educate donors about the importance of indirect costs
• Balancing mission delivery with administrative needs

Small Businesses

Small businesses should pay attention to:

• Provisional rates for new contractors
• Different rates for commercial vs. government work
• Requirements for cost accounting standards compliance
• Potential for higher scrutiny of cost allocations

Technology and Tools for Indirect Cost Management

Several software solutions can help organizations manage indirect costs more effectively:

• Enterprise Resource Planning (ERP) Systems: Comprehensive solutions like Oracle, SAP, or Workday that include grant management modules
• Grant Management Software: Specialized tools like Cayuse, Kuali Research, or InfoEd
• Time and Effort Reporting: Systems like Kronos or ADP for accurate labor distribution
• Spreadsheet Templates: Custom Excel or Google Sheets templates for smaller organizations
• Indirect Cost Calculators: Like the tool provided on this page for quick estimates

For organizations receiving federal funds, the Grants.gov website provides comprehensive resources on federal grant management, including indirect cost policies.

Future Trends in Indirect Cost Recovery

The landscape of indirect cost recovery is evolving with several important trends:

• Increased Transparency: Funders are demanding more detailed breakdowns of indirect cost allocations
• Performance-Based Rates: Some agencies are exploring rates tied to organizational performance metrics
• Simplified Methods: Efforts to reduce administrative burden for smaller awards
• Technology Integration: Greater use of AI and machine learning for cost allocation
• Global Harmonization: Movements toward more consistent international standards

Organizations that stay informed about these trends and adapt their practices accordingly will be best positioned to maximize legitimate indirect cost recovery while maintaining compliance with evolving requirements.
