What is a Research Budget?

A research budget is a detailed financial plan estimating all costs associated with conducting a research project. Grant applications require comprehensive budgets justifying every expense. Reviewers evaluate whether requested funding is appropriate, necessary, and reasonably priced. Well-constructed budgets demonstrate planning competence and increase funding probability.

Budget Components

• Personnel costs - Salaries, wages, fringe benefits
• Equipment - Major apparatus, computers, specialized tools
• Supplies - Consumables, minor equipment, materials
• Travel - Conferences, data collection, collaboration trips
• Participant costs - Incentives, compensation, recruitment
• Other direct costs - Subawards, consultants, services
• Indirect costs - Facilities and administrative overhead

Personnel Costs

Salary Calculations

Personnel typically represents the largest budget category:

Principal Investigator (PI)

• Annual salary: $120,000
• Percentage effort: 15% (academic year) + 2 months summer
• Calculation: ($120,000 × 0.15) + ($120,000 × 2/12) = $38,000/year

Graduate Research Assistant

• Stipend: $30,000/year × 2 years = $60,000
• Tuition remission: $25,000/year × 2 years = $50,000
• Total: $110,000

Project Coordinator (50% time)

• Annual salary: $50,000 × 50% × 3 years = $75,000

Fringe Benefits

Add fringe benefit rates (vary by institution):

• Faculty: Typically 25-35% of salary
• Staff: Typically 25-30% of salary
• Students: May include health insurance (~$3,000/year)

Example: $38,000 PI salary × 28% fringe = $10,640 in benefits

Salary Escalation

Include annual increases for multi-year projects:

• Year 1: $50,000
• Year 2: $50,000 × 1.03 = $51,500 (3% increase)
• Year 3: $51,500 × 1.03 = $53,045

Equipment Costs

Equipment Definition

Agencies define equipment as items costing above a threshold (typically $5,000) with useful life exceeding one year:

• Specialized laboratory equipment
• High-performance computers
• Audio/video recording systems
• Testing apparatus

Equipment Justification

Justify why equipment is necessary:

• Required for proposed methodology
• Not available through institutional resources
• Cost-effective compared to rental or service alternatives
• Will benefit multiple projects beyond funded work

Maintenance Costs

Some funders allow maintenance costs for specialized equipment:

• Service contracts
• Calibration services
• Software licensing fees

Supplies and Materials

Supply Categories

Detail consumable materials:

Laboratory supplies

• Reagents, chemicals, test kits
• Glassware, culture media
• Safety equipment

Office supplies

• Printing, copying
• Software subscriptions
• Cloud storage

Data collection materials

• Survey printing
• Gift card incentives
• Recording media

Per-Unit Costing

Provide unit costs for major supplies:

• DNA extraction kits: $15/kit × 200 samples = $3,000
• Survey printing: $0.50/survey × 1,000 surveys = $500

Travel Expenses

Conference Travel

Include professional development:

• Conference registration: $500
• Airfare: $800
• Hotel: $200/night × 4 nights = $800
• Per diem: $75/day × 4 days = $300
• Total per conference: $2,400

Data Collection Travel

Budget field site visits:

• Mileage: 500 miles × $0.67/mile = $335
• Lodging: $150/night × 3 nights = $450
• Meals: $60/day × 3 days = $180

Collaboration Travel

Include investigator meetings:

• Two annual meetings between collaborators at different institutions
• Travel costs for cross-site project coordination

Participant Costs

Incentive Payments

Compensate research participants:

• Survey completion: $25/participant × 150 participants = $3,750
• Interviews: $50/hour × 2 hours × 40 participants = $4,000
• Focus groups: $75/participant × 60 participants = $4,500

Recruitment Costs

Budget participant recruitment:

• Advertising (online, print, radio)
• Flyers and posters
• Recruitment staff time

Childcare and Transportation

Reduce participation barriers:

• Childcare during research visits: $15/hour
• Public transportation vouchers: $10/visit
• Parking validation

Other Direct Costs

Subawards

If partnering institutions conduct portions of research:

• Subaward amount
• Indirect costs on subaward (often capped at 8%)
• Scope of work justification

Consultant Fees

Expert consultation costs:

• Statistical consultant: $150/hour × 20 hours = $3,000
• Cultural advisor: $100/hour × 10 hours = $1,000
• Translation services: $0.25/word × 10,000 words = $2,500

Specialized Services

Outsourced technical services:

• Transcription: $1.50/minute × 60 interviews × 90 minutes = $8,100
• Data entry: $20/hour × 100 hours = $2,000
• Laboratory analyses: $500/sample × 50 samples = $25,000

Indirect Costs

Facilities and Administrative Costs (F&A)

Also called "overhead" or "indirect costs," F&A covers institutional expenses not directly attributable to specific projects:

• Building maintenance and utilities
• Library resources
• Administrative support (HR, accounting, grants management)
• General laboratory infrastructure

F&A Rates

Rates vary by institution and expense type:

• Modified Total Direct Costs (MTDC): Most common base, excludes equipment, participant incentives over $25k, and portions of subawards
• Typical rates: 45-60% for research universities, 8-10% for nonprofits

Example: $500,000 direct costs × 52% F&A rate = $260,000 indirect costs

F&A Rate Negotiations

Some funders:

• Cap indirect rates (e.g., 15%)
• Exclude indirect costs entirely
• Require institutional cost sharing for unrecovered F&A

Budget Justification

Detailed Explanations

Each budget line requires justification explaining:

• Why necessary: How item supports research objectives
• How calculated: Show computation (quantity × unit cost)
• Why reasonable: Justify pricing through quotes or established rates

Sample Justifications

Graduate Research Assistant: "We request two years of support for a doctoral student who will conduct literature review, assist with instrument development, collect and analyze data, and co-author publications. Two years allows adequate time for comprehensive training in mixed methods research while completing dissertation research aligned with project goals."

Transcription Services: "We will audio-record 60 semi-structured interviews averaging 90 minutes each. Professional transcription at $1.50/minute ensures accuracy while freeing research team time for analysis. Total: 60 interviews × 90 minutes × $1.50 = $8,100."

Multi-Year Budgets

Annual Budgets

Present separate budgets for each project year:

Year 1 Focus: Infrastructure development

• Equipment purchases
• Staff hiring and training
• Instrument development and piloting

Year 2 Focus: Data collection

• Peak participant recruitment
• Travel to field sites
• High consumable supply usage

Year 3 Focus: Analysis and dissemination

• Data analysis intensifies
• Conference travel increases
• Manuscript preparation

Cumulative Budgets

Also provide total costs across all years for each category and overall project cost.

Cost Sharing

Institutional Contributions

Some grants require cost sharing - institutional contributions beyond requested funding:

• Mandatory: Funder requires cost sharing
• Voluntary committed: Institution commits resources in proposal
• Voluntary uncommitted: Resources provided but not committed in proposal

Document cost-sharing:

• PI salary covered by institution
• Equipment provided by department
• Space allocation

Budget Alignment

Consistency with Methods

Budget must match proposed methods:

• If proposing 100 interviews, budget for 100 interviews
• If methodology requires specialized equipment, budget includes it
• If timeline shows three-year project, budget covers three years

Appropriate Sizing

Budget should be:

• Large enough to accomplish proposed work
• Not inflated beyond necessity
• Competitive with similar projects

Reviewers reject both underfunded projects unlikely to succeed and overfunded projects wasteful of resources.
