Guaranty Fee
How the SBA Guaranty Fee Works
SBA guarantees part of every 7(a) loan: 85% of loans of $150,000 or less and 75% of larger loans, with the guaranteed amount capped at $3.75 million. In exchange, SBA charges an upfront guaranty fee on the guaranteed portion, not on the full loan. The tier is set by the total loan amount, and the fee schedule in effect on the date your loan is approved is the one that applies. For FY2027, that covers loans approved from October 1, 2026 through September 30, 2027.
Three examples, each with a term longer than 12 months:
- $100,000 loan: 85% guaranteed is $85,000. At 2%, the fee is $1,700.
- $500,000 loan: 75% guaranteed is $375,000. At 3%, the fee is $11,250.
- $1,500,000 loan: 75% guaranteed is $1,125,000. The fee is 3.5% of the first $1,000,000 ($35,000) plus 3.75% of the remaining $125,000 ($4,687.50), for $39,687.50.
Loans with a maturity of 12 months or less pay 0.25% of the guaranteed portion. Manufacturers, listed food supply chain businesses, and businesses in rural areas pay no upfront fee on loans of $700,000 or less. The fee can usually be paid from loan proceeds, which adds it to the balance you repay; the calculator shows your payment both ways.

Underwriting
What Lenders Look At
- Debt service coverage: lenders want business cash flow to cover the new payment and existing debt with room to spare, commonly a DSCR of 1.25 or higher.
- Credit: personal credit for every owner of 20% or more, plus business credit and any delinquent federal debt.
- Equity: a cash injection that fits the deal, typically 10% or more for acquisitions and the set 10%, 15% or 20% contribution on a 504 project.
- Ownership: under current SBA rules, all direct and indirect owners must be U.S. citizens or U.S. nationals.
- Use of funds: a clear, documented plan for every dollar, matched to the right program and term.

Frequently Asked Questions
SBA Loan Calculator: Common Questions
What is the SBA 7(a) guaranty fee in FY2027?
For 7(a) loans approved from October 1, 2026 through September 30, 2027, the upfront guaranty fee is charged on the SBA-guaranteed portion: 2% for loans of $150,000 or less, 3% for loans of $150,001 to $700,000, and 3.5% on the guaranteed portion up to $1,000,000 plus 3.75% above that for larger loans. Loans with a maturity of 12 months or less pay 0.25%. Manufacturers, listed food supply chain businesses, and rural businesses pay 0% on loans of $700,000 or less.
Can the guaranty fee be added to the loan?
Many borrowers pay the upfront fee from loan proceeds, which adds it to the balance they repay. The calculator shows your payment both ways so you can see the difference. Your lender confirms how the fee is handled on your loan.
What is the maximum interest rate on an SBA 7(a) loan?
SBA caps variable rates at a spread over the base rate that depends on loan size: 6.5 percentage points for loans of $50,000 or less, 6 points up to $250,000, 4.5 points up to $350,000, and 3 points above $350,000. Within those caps, the lender sets the rate based on your file.
How is an SBA 504 loan structured?
A typical 504 project is financed with a bank first-lien loan for about 50% of the cost, a Certified Development Company debenture for about 40%, and a borrower contribution of 10%. The contribution rises to 15% for a new business or a special-purpose property, and 20% when both apply. The debenture is capped at $5 million, or $5.5 million for manufacturing or energy projects.
Can I combine a 7(a) loan and a 504 loan?
Yes. Since July 4, 2026, eligible borrowers can combine up to $5 million of 7(a) financing with up to $5 million of 504 financing, for up to $10 million in total SBA-backed financing. Your financing team can tell you whether a combined structure fits your project.
Can I use an SBA loan to buy a gas station or convenience store?
Yes. Gas station and convenience store purchases often use SBA 7(a) financing, and SBA 504 can fit when the project centers on owner-occupied real estate. When real estate is part of the deal, terms can run up to 25 years. See gas station and convenience store financing.
