SBA Loan Costs: What You'll Actually Pay to Borrow
SBA loans are often described as "affordable small business financing" — which is accurate relative to merchant cash advances and hard money lenders, but not accurate relative to what a well-qualified borrower pays for a conventional bank loan. The SBA guarantee fee, which funds the SBA program, adds a real upfront cost that most borrowers don't see in the headline rate. On a $500,000 loan, it can exceed $13,000 before you pay a dollar of interest.
This guide breaks down every cost in every major SBA loan program: guarantee fees, interest rates, packaging fees, and what the total borrowing cost looks like over a full loan term.
The SBA 7(a) Loan: Cost Structure
The 7(a) is the SBA's flagship program — used for working capital, equipment, real estate, and business acquisition. It's the most flexible and most commonly used SBA product. The cost has three components: the guarantee fee, the interest rate, and ancillary fees.
SBA 7(a) Guarantee Fees (2026)
The SBA charges lenders a guarantee fee based on the guaranteed portion of the loan and the loan term. Lenders pass this fee to borrowers at closing. Fees change annually — the figures below reflect FY2026:
| Loan Amount | Guaranteed Portion | Fee Rate | Fee on a 10-yr Loan |
|---|---|---|---|
| Up to $150,000 | 85% guaranteed | 0% (waived) | $0 |
| $150,001–$500,000 | 75% guaranteed | 2.0% of guaranteed portion | $500K loan: $7,500 |
| $500,001–$700,000 | 75% guaranteed | 3.0% of guaranteed portion | $700K loan: $15,750 |
| $700,001–$5,000,000 | 75% guaranteed | 3.5% of guaranteed portion | $1M loan: $26,250 |
On a $500,000 loan over 10 years: 75% guaranteed = $375,000 guaranteed portion. Fee = $375,000 × 2.0% = $7,500. That fee is paid at closing or rolled into the loan — if rolled in, you pay interest on it for the full term. The SBA also charges an annual service fee of 0.55% of the outstanding guaranteed balance, which flows through the lender and is reflected in the effective rate.
SBA 7(a) Interest Rates
SBA 7(a) rates are variable, capped by the SBA at prime rate plus a spread that varies by loan size and term. With prime at 7.5% in early 2026:
| Loan Size | Term | Max Rate (Prime + Spread) | Effective Rate at Prime 7.5% |
|---|---|---|---|
| Up to $25,000 | Under 7 yrs | Prime + 4.25% | 11.75% |
| $25,001–$50,000 | Under 7 yrs | Prime + 3.25% | 10.75% |
| $50,001–$250,000 | 7 yrs or more | Prime + 2.75% | 10.25% |
| Over $250,000 | 7 yrs or more | Prime + 2.25% | 9.75% |
Most 7(a) lenders charge the maximum allowed rate. Some preferred lenders — high-volume SBA banks — price slightly below the cap to win deals. The SBA Express program (faster approval, up to $500K) typically prices at prime + 4.5–6.5%, reflecting the higher risk the lender retains (only 50% guaranteed vs 75–85% for standard 7(a)).
The SBA 504 Loan: Real Estate and Heavy Equipment
The 504 loan is structured differently from the 7(a). It's a two-part financing package designed for fixed assets: commercial real estate and equipment with a useful life over 10 years. It is not available for working capital.
The structure: a conventional bank lends 50% of the project cost (at market rates), a Certified Development Company (CDC) lends 40% (the SBA-guaranteed portion), and the borrower contributes 10%. For startups or single-purpose properties, the borrower's contribution rises to 15–20%.
| Component | Share | Lender | Rate |
|---|---|---|---|
| Bank portion | 50% | Conventional bank | Market rate (typically prime + 1–2%) |
| CDC portion | 40% | SBA-backed CDC | Fixed ~6.0–6.5% (tied to 10-yr Treasury + spread) |
| Borrower contribution | 10–20% | Equity / down payment | N/A |
The 504 CDC portion carries a fixed rate set at debenture sale — typically 1.3–1.4% above the 10-year Treasury at time of close. In early 2026, that produces rates in the 6.0–6.5% range. That rate is fixed for the full 20- or 25-year term, which is the core appeal of the 504: long-term fixed-rate commercial real estate financing at rates significantly below conventional commercial mortgages.
504 Fees
The 504 is more expensive at closing than the 7(a) because two loan closings occur (bank + CDC). Typical closing costs on the CDC portion run 2.5–3.0% of the CDC loan amount, including the SBA guarantee fee, CDC processing fee, and third-party costs (appraisal, environmental, title). On a $400,000 CDC loan (40% of a $1M project), that's $10,000–$12,000 in 504 closing costs, on top of conventional bank closing costs on the $500,000 bank portion.
SBA Microloan: Small Amounts, Higher Rates
SBA Microloans are issued through nonprofit intermediaries, not banks. Maximum loan: $50,000. Average loan: approximately $14,000. Terms up to 6 years.
The rate range is 8–13% — higher than larger 7(a) loans because of the smaller loan size (fixed costs spread over a smaller principal) and the profile of borrowers who typically qualify only for Microloans. There is no SBA guarantee fee on Microloans. Some intermediaries charge origination fees of 1–3%.
Microloans are particularly useful for businesses that can't qualify for bank-level 7(a) loans: newer businesses, owners with credit scores below 680, or businesses in sectors that bank lenders avoid (food carts, small childcare, home crafts). The intermediary often provides required technical assistance — mentoring, bookkeeping help — as a condition of the loan.
Total Borrowing Cost: Real Examples
A $250,000 SBA 7(a) loan for a restaurant startup, 10-year term at 10.25% (prime + 2.75%):
| Cost Item | Amount | Notes |
|---|---|---|
| Loan principal | $250,000 | |
| SBA guarantee fee | $3,750 | 75% guaranteed = $187,500 × 2.0% |
| Lender origination fee | $1,250–$2,500 | Typical: 0.5–1.0% of loan amount |
| Total interest (10 yrs at 10.25%) | ~$145,000 | Amortized monthly payment ~$3,290/mo |
| Total cost of borrowing | ~$150,000 | 60% of principal in interest + fees |
That 60% figure — $150,000 in total cost to borrow $250,000 — is the number most borrowers don't compute before applying. The monthly payment is manageable ($3,290/mo), but the 10-year total cost is what matters for the business model. A restaurant generating $800K/year in revenue absorbs this comfortably. A $250K restaurant generating $400K/year is debt-stressed from day one.
Who Qualifies (and What "Qualified" Actually Means)
SBA lenders make the credit decision — the SBA sets the floor. Standard 7(a) requirements:
- Credit score: Most preferred lenders want 680+. Some will go to 650 with strong cash flow. Below 640 typically requires the Microloan route or a non-preferred lender willing to do more manual underwriting.
- Time in business: 2+ years preferred for most programs. Startups can qualify, but the underwriting is harder and the collateral requirements are higher. SBA Express is more startup-friendly.
- Collateral: The SBA does not require collateral to fully secure the loan, but lenders will take whatever is available — business assets, equipment, real estate, and sometimes a lien on the owner's primary residence if business assets are insufficient. The SBA requires lenders to collateralize with available assets; they cannot decline a loan solely for lack of collateral if the borrower otherwise qualifies.
- Down payment: 10–30% equity injection required for acquisition or startup deals. Existing businesses refinancing working capital debt often have no down payment requirement.
- Personal guarantee: Required from anyone owning 20%+ of the business. Non-negotiable.
Fee Waivers: When You Pay Less
The SBA periodically waives guarantee fees as a policy stimulus. In FY2021 and FY2022, fees were waived for loans under $5M as part of COVID relief. As of FY2026, waivers apply to loans up to $150,000 only.
The SBA Veterans Advantage program waives guarantee fees for veteran-owned businesses on loans up to $500,000. This saves the 2.0% fee — on a $500,000 loan, that's $7,500 waived. Active duty, reservists, National Guard members, and qualifying spouses also qualify.
Community Advantage loans (through CDCs, up to $350,000) are designed for underserved markets and small lenders. Guarantee fees are reduced compared to standard 7(a).
SBA Loan vs. Alternatives: When the Cost Is Worth It
SBA loans make financial sense when:
- You need a long term (10 years for working capital, 25 years for real estate). Conventional business loans typically max at 5–7 years, creating a higher monthly payment for the same principal.
- You don't have the assets for a fully collateralized conventional loan. The SBA guarantee covers up to 85% of the risk, enabling loans banks wouldn't otherwise approve.
- You're buying a franchise on the SBA Franchise Registry. Registry brands have pre-approved FDD eligibility, significantly faster underwriting (days vs weeks).
- You're a veteran. The fee waiver is real money — $7,500 on a $500K loan is worth taking seriously.
SBA loans make less sense when:
- You qualify for a conventional commercial loan at prime + 1%. The guarantee fee adds cost that exceeds the rate advantage for well-qualified borrowers.
- You need funds in 2–4 weeks. Standard 7(a) underwriting takes 30–90 days. SBA Express (up to $500K) is 36 hours for approval but 2–4 weeks to close. Banks offering conventional business loans can close faster.
- The loan amount is under $50K. At this size, the Microloan program or a credit union business loan is less paperwork with comparable rates.
Frequently Asked Questions
What is the current SBA loan interest rate?
SBA 7(a) rates in early 2026 range from 9.75% to 11.75% depending on loan size and term. Rates are variable (prime-based) and reset when the prime rate changes. The cap is set by the SBA; most lenders charge the maximum allowed. The 504 CDC rate is fixed and currently runs 6.0–6.5% for the CDC portion.
What is the SBA guarantee fee and how much is it?
The SBA guarantee fee compensates the SBA for guaranteeing a portion of the loan against default. It's charged on the guaranteed portion of the loan: 0% for loans under $150K, 2.0% for $150K–$500K (75% guaranteed), rising to 3.5% for loans over $700K. Veterans are exempt from fees up to $500K.
How long does SBA loan approval take?
Standard 7(a): 30–90 days from application to funding. SBA Express: 36-hour approval decision, 2–4 weeks to close. SBA Preferred Lenders (major banks with delegated authority) can often close standard 7(a) loans in 45–60 days. The bottleneck is usually document collection, not SBA processing.
Can a startup get an SBA loan?
Yes, but underwriting is stricter. Most 7(a) lenders require a business plan with financial projections, owner industry experience, and a 10–30% equity injection. Startups without operating history are evaluated on personal creditworthiness and the strength of the business concept. SBA Microloans are the most accessible for pre-revenue startups.
