Budget Justification Template

Overview

A budget justification provides detailed explanation for each budget line item, demonstrating that costs are necessary, reasonable, and directly related to the proposed research. The justification should be detailed enough for reviewers to understand and assess cost reasonableness.

Key Principles:

• Justify EVERY line item in terms of the research plan

• Explain calculations clearly

• Show that costs are necessary for the proposed work

• Demonstrate cost-effectiveness where possible

• Follow agency-specific formats and requirements

Personnel (Salaries and Wages)

Senior Personnel

Principal Investigator: [Name, Title]

Effort: [X] calendar months ([Y]% FTE) per year

Justification: The PI will provide overall scientific leadership, supervise all research activities, mentor graduate students and postdocs, analyze data, prepare manuscripts, and report to the funding agency. The PI will be responsible for [specific activities related to aims]. [X] months of effort is necessary given the scope of the project and the PI's other commitments ([describe other activities briefly]).

Calculation:

• Year 1: [Annual salary] × [% effort] × [inflation factor if applicable] = $[amount]

Dr. Smith's remaining effort supports teaching (3 months), other research projects (4 months), and administrative duties (2.5 months).

Calculation:

• Year 1: $120,000 × 0.2083 = $25,000

• Years 2-5: 3% annual increase

Consortium/Contractual Costs

(For collaborating institutions)

[Institution Name] Subaward

Total costs: $[amount] per year

Justification: [Collaborating institution] will perform [specific work related to which aims]. Dr. [PI name at institution] will lead these efforts. This collaboration is essential because [why this expertise/resource is needed and not available at your institution].

Work to be performed:

• [Task 1]

• [Task 2]

• [Task 3]

Detailed budget and justification from [institution] are included as a subaward/consortium application.

Example: University of California San Diego Subaward

Total costs: $100,000/year

Justification: UCSD will perform all mass spectrometry-based metabolomics and proteomics analyses for Aims 1-2. Dr. Michael Williams, Director of the UCSD Metabolomics Core, will lead these efforts. This collaboration is essential because our institution lacks the specialized mass spectrometry platforms (Orbitrap Fusion, QTOF) and expertise required for these analyses. UCSD has extensive experience with T2D metabolomics and proteomics, having processed >5,000 clinical samples.

Work to be performed:

• Sample processing and metabolite/protein extraction (Years 1-3)

• LC-MS/MS analysis on Orbitrap Fusion and QTOF platforms

• Data processing, quality control, and statistical analysis

• Quarterly meetings to discuss results and plan analyses

Budget includes: Personnel (50% technician, 10% Dr. Williams), supplies, and instrument time. Detailed subaward budget attached.

Note: Consortium F&A limited to 8% of total costs per NIH policy.

Indirect Costs (Facilities & Administrative)

Rate: [X]% of Modified Total Direct Costs (MTDC)

MTDC Excludes: Equipment, capital expenditures, charges for patient care, participant support costs, rental costs of off-site facilities, scholarships and fellowships, and the portion of each subaward in excess of $25,000.

Justification: Indirect cost rate is based on our institution's federally negotiated rate agreement with [DHHS/agency], effective [dates]. This rate covers institutional costs for facilities (building depreciation, operations, maintenance) and administration (sponsored projects office, accounting, library, etc.) that support research.

Example: Facilities & Administrative Costs: 57% of MTDC (on-campus rate)

Justification: Our institution's federally negotiated F&A rate with DHHS is 57% for on-campus research, effective July 1, 2023 - June 30, 2027. This rate covers facilities costs (building depreciation, utilities, operations and maintenance) and administrative costs (sponsored projects administration, accounting, library, general administration).

Calculation example (Year 1):

• Total direct costs: $550,000

• Less: Equipment ($425,000), participant support ($65,000), consortium F&A ($8,000)

• MTDC base: $52,000

• Indirect costs: $52,000 × 0.57 = $29,640

• Provide detailed calculations showing your work

• Explain why the amount is necessary and reasonable

• Use institutional or national standards for rates

• Show cost-effectiveness where possible

• Include escalation (inflation) for out-years

• Be specific about equipment models, conference names, etc.

❌ Don't:

• Use vague language ("miscellaneous supplies")

• Forget to justify every line item

• Over-budget for contingency

• Include costs unrelated to the proposed work

• Underestimate costs (creates problems if funded)

• Forget agency-specific cost limitations (salary caps, F&A exclusions)

Agency-Specific Notes
