Understanding SBA Loan Rates & Terms
How SBA Interest Rates Work
SBA loan interest rates are typically tied to the Wall Street Journal Prime Rate and expressed as “Prime + X%.” The SBA sets maximum allowable spreads, but individual lenders may offer lower rates based on your credit profile, collateral, and business financials.
For SBA 7(a) loans, the maximum variable rate is Prime + 3.0% for loans of $50,000 or less, and Prime + 2.75% for loans between $50,001 and $250,000. Loans above $250,000 cap at Prime + 2.25%.
SBA 7(a) vs. 504 Loans
SBA 7(a) Loans
- Up to $5 million
- Variable or fixed rates
- Terms up to 25 years (real estate) or 10 years (working capital)
- General-purpose — equipment, working capital, refinancing, acquisition
SBA 504 Loans
- Up to $5.5 million (CDC portion)
- Below-market fixed rates on the CDC portion
- 10- or 20-year terms
- Real estate and major equipment only — requires 10% down
Factors That Affect Your Rate
The calculator above estimates your rate range based on the same factors real lenders evaluate:
- Credit score: Higher personal credit typically earns lower spreads above Prime. Most SBA lenders require a minimum FICO of 620, but stronger scores unlock better terms.
- Time in business: Startups (under 2 years) are considered higher risk and typically face higher equity requirements and rates.
- Cash flow: Lenders want to see that your business can comfortably cover the loan payment — typically 1.25× the monthly payment or more.
- Equity injection: The standard minimum is 10%, but startups, weaker credit profiles, or businesses with thin cash flow may need 15–30%.
- Loan size: Larger loans often qualify for tighter spreads. SBA caps the maximum spread at Prime + 2.25% for loans over $250,000.
About the SBA Guarantee Fee
Every SBA 7(a) loan carries an upfront guarantee fee — this is an SBA fee, not a lender fee, and every SBA-approved lender is required to collect it. The fee is based on the loan amount and the guaranteed portion:
- Loans up to $150,000: 2% of the guaranteed portion (85% guarantee)
- $150,001 – $700,000: 3% of the guaranteed portion (75% guarantee)
- $700,001 – $5,000,000: 3.5% on the first $1M guaranteed, 3.75% on amounts above $1M
This fee can typically be financed into the loan, so you don't always need to pay it out of pocket at closing.
