If you're building your first SBIR budget, you've probably Googled "how much does SBIR pay" and landed on the SBA's statutory cap: $275,000 for Phase I. That number is misleading. Actual SBIR award amounts by agency range from $50,000 to $314,000 for Phase I, and median awards differ from advertised ceilings by 40-80%. Budgeting around the wrong number can waste months of planning.
This guide compares what the major SBIR-participating federal agencies advertise versus what they actually pay, using real award data from USAspending.gov (FY2023-FY2025). The SBA lists 11 participating agencies, but several (like DOD) run multiple independent programs through their components. We cover Phase I, Phase II, and total funding paths -- so you can build a realistic budget before you invest 40-80 hours in an application.
Why Advertised SBIR Award Amounts Are Misleading
Three structural problems cause the disconnect between what agencies advertise and what they actually pay.
Problem 1: Statutory caps are not award amounts. The SBA sets a statutory guideline of $275,000 for SBIR Phase I awards. But individual agencies set their own ceilings within (or sometimes above) that guideline:
- NIH awards up to $314,000 for Phase I
- NSF offers $305,000
- DOD branches range from $50,000 to $250,000
The statutory cap is a ceiling for the ceiling -- not a budget number.
Problem 2: Sub-agency variation is invisible. NIH has 21 Institutes and Centers (ICs), each with different award norms. A Phase I from NIMH (National Institute of Mental Health) may come in at $275,000, while NCI (National Cancer Institute) routinely awards $314,000. Searching "NIH SBIR Phase I amount" gives you one number for a 21-number problem.
Problem 3: Web sources are stale. NSF increased its Phase I award from $175,000 to $305,000 in 2023 when it consolidated under the TIP directorate -- a 74% increase. Many online sources still cite the old number. Agency pages cite statutory maximums rather than typical awards. AI search engines compound the problem by synthesizing outdated sources into confident-sounding wrong answers.
SBIR Award Amounts by Agency: The Comparison Table
Here's what agencies advertise versus what USAspending data shows they actually pay (FY2023-FY2025 Phase I awards).
| Agency | Advertised Phase I | Actual Median Phase I | Actual Range | Key Quirk |
|---|---|---|---|---|
| NIH | "Up to $275K" (SBA guideline) | $275K | $225K-$314K | Varies by IC -- 21 different norms |
| NSF | $305K | $290K | $275K-$305K | Increased from $175K in 2023 |
| DOD -- Army | ~$200K | $175K | $150K-$250K | Contract-based, not grant-based |
| DOD -- Navy | ~$200K | $180K | $140K-$250K | Component-specific topics |
| DOD -- Air Force | ~$200K | $175K | $50K-$250K | AFWERX Open Topics can be lower |
| DOD -- DARPA | $225K-$250K | $225K | $200K-$250K | Fewer awards, higher selectivity |
| DOE | $250K | $240K | $200K-$275K | Energy-specific, smaller program |
| NASA | $175K | $150K | $125K-$175K | Historically lower Phase I |
| USDA | $125K-$175K | $130K | $100K-$175K | Smallest Phase I among major agencies |
| HHS (non-NIH) | Varies | Varies | $100K-$250K | AHRQ, HRSA, CDC each differ |
| EPA | $125K | $120K | $100K-$125K | Small program, few awards annually |
| DHS | $200K | $175K | $150K-$200K | Sporadic solicitation cycles |
The gap matters. If you budget for $275K based on the SBA guideline but target DOD Army, you're overestimating by $100K. If you use an outdated NSF figure of $175K, you're underestimating by $130K. Either mistake wastes your time.
Agency-by-Agency Breakdown: Phase I
NIH -- The Largest and Most Complex
NIH runs the biggest SBIR program in the federal government, awarding over $1 billion annually across SBIR and STTR. But "NIH SBIR" is not one program -- it's 21 programs, one per Institute and Center.
What NIH advertises: The NIH SBIR page cites the SBA guideline of $275,000 for Phase I (R43 mechanism) and notes that higher amounts may be requested with justification.
What NIH actually pays: Phase I awards range from $225,000 to $314,000 depending on the IC. NCI and NHLBI frequently award at or near $314,000. NIMH and NIBIB typically award $275,000-$298,000. Smaller ICs like NCCIH may award $225,000.
Why the variation: Each IC has its own budget, review panels, and award norms. A Phase I application to NIMH and an identical application to NCI could receive different award amounts based purely on which IC reviews it.
What founders get wrong: Budgeting $275K for all NIH applications. If you're targeting NCI, you can request $314K. If you're targeting a smaller IC, $275K may be the actual ceiling. Check the specific IC's recent awards before setting your budget.
NSF -- The Most Improved
NSF made the largest recent change to its SBIR program when it consolidated under the TIP (Technology, Innovation, and Partnerships) directorate in 2023, significantly increasing Phase I awards.
What NSF advertises: $305,000 for Phase I through the TIP directorate.
What NSF actually pays: Median awards are $290,000, with most falling in the $275,000-$305,000 range.
The critical update founders miss: NSF increased the Phase I ceiling from $175,000 to $305,000 -- a 74% jump. Many online resources, AI search engines, and even some grant consultants still cite the old $175,000 figure. If you're budgeting for an NSF SBIR based on pre-TIP numbers, you're leaving $130,000 on the table.
Budget tip: Request $305,000. NSF is transparent about its ceiling and awards at or near it consistently.
DOD -- The Branch-by-Branch Puzzle
DOD SBIR is not one program -- it's a collection of programs run by individual military branches, defense agencies, and special commands. Each sets its own award amounts within broad DOD guidelines.
What DOD advertises: "Approximately $200,000" for Phase I appears on most DOD SBIR overview pages.
What DOD actually pays: It depends on the branch.
| DOD Component | Typical Phase I | Notes |
|---|---|---|
| Army | $150K-$250K | Median ~$175K |
| Navy | $140K-$250K | Median ~$180K |
| Air Force | $50K-$250K | AFWERX Open Topics can start at $50K |
| DARPA | $200K-$250K | Fewer awards, higher per-award |
| SOCOM | $150K-$200K | Niche topics |
| MDA | $150K-$200K | Missile defense focus |
The DOD difference: DOD SBIR awards are contracts, not grants. This changes the funding mechanism, reporting requirements, and intellectual property rules. It also means DOD awards show up differently in federal databases -- you need to search contracts, not grants, in USAspending.
What founders get wrong: Treating all DOD components as interchangeable. An Air Force AFWERX Open Topic at $50K-$75K is a fundamentally different opportunity than a DARPA SBIR at $225K. Target the component, not just "DOD."
DOE -- Energy-Focused and Underrated
DOE runs a mid-sized SBIR program focused on energy technology, clean energy, nuclear, and advanced computing.
What DOE advertises: Up to $250,000 for Phase I.
What DOE actually pays: Median around $240,000, with most awards in the $200,000-$275,000 range.
DOE's SBIR program is often overlooked by founders who default to NIH or NSF. If your technology touches energy storage, grid infrastructure, advanced materials, nuclear, or high-performance computing, DOE may offer less competition than the bigger programs.
NASA -- Lower Phase I, Stronger Phase II Path
NASA SBIR has historically offered lower Phase I awards but provides a strong pathway to Phase II and procurement contracts.
What NASA advertises: Up to $175,000 for Phase I.
What NASA actually pays: Median around $150,000, with most awards in the $125,000-$175,000 range.
NASA's lower Phase I means you need to scope tightly -- $150K funds 6-9 months of a focused feasibility study, not a full prototype build. But NASA's Phase II ($750K-$850K) and the procurement pathway (Phase III) can be substantial for aerospace, remote sensing, and advanced materials companies.
Smaller Agencies: USDA, EPA, DHS, ED, NOAA
Several agencies run SBIR programs that are smaller but potentially less competitive.
| Agency | Phase I Range | Annual Awards | Best For |
|---|---|---|---|
| USDA | $100K-$175K | ~100 | Ag-tech, food safety, rural broadband |
| EPA | $100K-$125K | ~25-40 | Environmental tech, water treatment |
| DHS | $150K-$200K | ~50 | Cybersecurity, border tech, disaster response |
| ED | $125K-$175K | ~15-25 | Ed-tech, learning assessment |
| NOAA | $125K-$175K | ~20-30 | Ocean tech, weather, climate data |
These programs don't get the attention of NIH, NSF, or DOD, which means lower competition. If your technology maps to their mission areas, the lower award amounts may be offset by significantly higher win rates.
Phase II: Where the Real Money Is
Phase I is a feasibility study. Phase II is where you build the product -- and where award amounts get serious.
| Agency | Phase I Median | Phase II Median | Total Funding Path |
|---|---|---|---|
| NIH | $275K | $1.5M-$2.8M (varies by IC) | $275K Phase I + $1.5M-$2.8M Phase II + competitive renewals |
| NSF | $290K | $1.5M-$2M | $305K Phase I + $2M Phase II |
| DOD | $175K | $500K-$1.5M | $175K Phase I + $1M Phase II + sole-source Phase III |
| DOE | $240K | $1M-$1.6M | $250K Phase I + $1.6M Phase II |
| NASA | $150K | $750K-$850K | $175K Phase I + $850K Phase II + procurement contracts |
The Phase II multiplier matters. Per USAspending data (FY2023-FY2025), NIH Phase II awards in fast-growing areas like digital health can reach $2.8M -- more than 10x the Phase I amount. DOD Phase II plus the sole-source Phase III pathway can lead to multi-million dollar production contracts. When evaluating agencies, look at the total funding path, not just Phase I.
DOD's unique advantage: Phase III. DOD SBIR Phase III awards are sole-source contracts -- no competition required. If your Phase I and II succeed, the DOD component can issue a Phase III production contract without a new solicitation. This is the single most valuable aspect of DOD SBIR that founders routinely overlook.

How to Verify SBIR Award Amounts Before You Budget
Don't take anyone's word for SBIR award amounts by agency -- including ours. Here's how to verify the numbers yourself using the same methodology behind every Cada grant roadmap.
Tier 1: USAspending.gov (Authoritative)
USAspending.gov is the US Treasury's official record of all federal spending. Every SBIR award ends up here. It's the most reliable source for actual award amounts -- not what agencies plan to pay, but what they did pay.
How to use it: Search by CFDA number (each agency has assigned codes), filter by fiscal year, and look at actual award amounts for SBIR Phase I or Phase II in your technology area. You'll get median, range, and the full distribution.
Why it's better than Google: USAspending shows you what companies actually received, including stealth-mode awardees who don't do press releases. USAspending regularly surfaces 5-10 funded competitors per technology area that are invisible to standard web searches.
The catch: You need to know the right CFDA numbers and filtering strategies. NIH awards require filtering by award ID prefix (R43/R44 for SBIR, R41/R42 for STTR). DOD awards are contracts, not grants, and need amount caps to exclude large Phase III production contracts. NSF's consolidated CFDA (47.084) covers the entire TIP directorate, so you need keyword filters to isolate SBIR.
Tier 2: Agency Solicitation Pages
Read the actual NOFO (Notice of Funding Opportunity) on Grants.gov or SAM.gov. The solicitation text contains the definitive award ceiling for that specific competition.
Why you need this alongside USAspending: USAspending tells you what past awards looked like. The current solicitation tells you what this cycle's ceiling is. Agencies can change ceilings between cycles.
Tier 3: SBIR.gov and Agency Databases
SBIR.gov maintains a searchable database of SBIR awards. NIH Reporter provides NIH-specific award data with weekly updates. These are useful for spot-checking and for finding technology-specific award patterns.
The Pitfalls to Avoid
| Pitfall | Why It Happens | How to Avoid |
|---|---|---|
| Using a generic "SBIR pays $275K" | SBA statutory cap gets cited as universal truth | Check the specific agency's actual awards |
| Citing NSF at $175K | Old figure still circulates widely | NSF increased to $305K under TIP directorate in 2023 |
| Treating DOD as one program | "DOD SBIR" overview pages give one number | Check the specific component (Army, Navy, AF, DARPA) |
| Missing IC variation at NIH | NIH awards span $225K-$314K by IC | Check the specific IC's recent awards |
| Trusting AI search engine answers | AI engines synthesize outdated sources | Verify against USAspending or current solicitation text |
Which SBIR Agencies Are Growing?
SBIR funding levels shift with agency budgets, congressional appropriations, and policy priorities.
Growing:
- NSF: The TIP directorate has expanded SBIR funding substantially since 2023. The Phase I ceiling increased 74% (from $175K to $305K), and the program now accepts a broader range of technology areas. Total NSF SBIR/STTR obligations have trended upward since the TIP directorate consolidation.
- DOE: The Inflation Reduction Act and clean energy policy priorities have driven increased SBIR funding at DOE, particularly in energy storage, grid modernization, and advanced manufacturing. DOE SBIR solicitation topics have expanded year-over-year from FY2023 to FY2025.
- ARPA-H: Launched in 2022 within HHS, ARPA-H uses Other Transaction Authority (OTA) -- not SBIR -- to fund early-stage health research. It is not an SBIR-participating agency, but it is an emerging non-dilutive funding option worth tracking alongside your SBIR strategy. Limited historical data so far.
Stable:
- NIH: The largest SBIR program remains well-funded. Award amounts are stable, though competition remains intense.
- DOD: Consistent SBIR funding across branches. Individual component budgets fluctuate with defense priorities.
Uncertainty:
- SBIR reauthorization: The SBIR/STTR program requires periodic congressional reauthorization. During reauthorization gaps, some agencies pause new solicitations. Factor reauthorization timing into your application calendar.
What this means for targeting: If you have flexibility in which agency to target, lean toward agencies with growing budgets. Less competition for more money is the ideal combination.
Frequently Asked Questions
How much does SBIR Phase I actually pay?
SBIR Phase I awards range from $50,000 (DOD Air Force AFWERX Open Topics) to $314,000 (NIH NCI), with most agencies paying between $150,000 and $305,000. The commonly cited SBA statutory cap of $275,000 is a guideline, not a universal award amount. Always check your specific target agency's actual awards on USAspending.gov.
Which SBIR agency pays the most?
For Phase I, NIH (up to $314K) and NSF ($305K) offer the highest awards. For total funding path including Phase II and beyond, NIH and DOD offer the highest potential -- NIH through large Phase II awards ($1.5M-$2.8M), and DOD through the sole-source Phase III production contract pathway that can reach multi-million dollar values.
Can I budget for the statutory maximum?
No. Budget for the agency's typical award, not the statutory ceiling. At NIH, the typical award depends on which IC you're targeting. At DOD, it depends on the military branch. Request the amount that matches your actual scope of work -- over-requesting relative to your proposed work triggers reviewer skepticism.
How do I find actual award amounts for my specific technology area?
Use USAspending.gov to search by CFDA number and technology keywords for your target agency. Filter to the last 2-3 fiscal years. This gives you the actual distribution of awards in your space -- median, range, and funded competitors. For NIH, supplement with NIH Reporter. For DOD, search contract awards specifically.
What is the average SBIR Phase I award amount?
There is no single "average SBIR Phase I award amount" because it varies dramatically by agency. The SBA statutory guideline is $275,000, but actual medians range from $120K (EPA) to $290K (NSF). NIH averages around $275K but varies by IC ($225K-$314K). DOD averages $175K across branches. The most useful number is the median for your specific target agency and sub-agency -- not a cross-agency average.
What is the SBIR success rate by agency?
SBIR acceptance rates vary by agency, program area, and solicitation cycle. Approximate Phase I success rates: NIH runs around 20-25% across study sections, NSF sits at 15-20%, and DOD varies widely by solicitation topic (some have 5-10% rates, others 30-40% for niche topics with few applicants). Your individual odds depend on how well your technology matches the program's mission and how competitive your application is relative to funded recipients in your area.
What's the difference between SBIR Phase I and Phase II awards?
Phase I is a feasibility study (typically $150K-$314K over 6-12 months). Phase II is full R&D (typically $750K-$2.8M over 18-24 months). Phase II awards are 4-10x larger than Phase I. You need a successful Phase I to apply for Phase II, though some agencies offer "Direct to Phase II" pathways for companies with existing feasibility data.
Building Your SBIR Budget: The Bottom Line
The SBIR award amount you should budget for depends on three variables: which agency, which sub-agency or component, and which fiscal year. The SBA's $275K statutory cap is a starting point, not an answer.
Here's the practical framework:
- Identify your target agency and sub-agency. NIH NIMH is different from NIH NCI. DOD Army is different from DOD DARPA.
- Check actual recent awards. USAspending.gov gives you real data. The current solicitation gives you the ceiling.
- Budget for the median, not the max. Unless you have a strong justification for exceeding the typical award, budget in line with what the agency actually pays.
- Factor in Phase II. Phase I is the entry ticket. Phase II is where real product development happens. Evaluate agencies on total funding path, not just Phase I.
