How It Works
Pricing an SBA 7(a) loan means looking past the headline interest rate to the monthly payment you will actually carry, guarantee fee included. The estimate here lets you weigh that real cost against a conventional loan so a 2026 financing decision rests on numbers rather than guesswork.
Payments come from a standard amortization formula, layered with the SBA guarantee fee that runs from 0% to 3.75% of the guaranteed portion for 2026, depending on how large the loan is. Side by side, the tool lays out total interest and monthly payments for both the SBA and conventional paths so the trade-offs are visible at a glance.
That guarantee fee is an upfront charge, and because borrowers frequently roll it into the loan, it quietly raises the principal you end up financing. Closing costs are a separate matter the calculator leaves out, so budget for those on top of whatever figure you see here.
Example: $250,000 SBA 7(a) Loan
- 1 Input a $250,000 loan amount, a 10-year term, and an interest rate of 8.5%. For an SBA 7(a) loan of this size, the guarantee fee is 3.0% of the guaranteed portion.
- 2 The calculator will add the guarantee fee to the principal (assuming 75% guaranteed, so $250,000 + (0.75 * $250,000 * 0.03) = $255,625 total financed). It then calculates the monthly payment based on this new principal.
- 3 The result will show an estimated monthly SBA loan payment of approximately $3,140. It will also display the total interest paid over the loan term and allow you to compare this to a conventional loan at a different rate.
- 4 This payment includes the financing of the SBA guarantee fee. Comparing this to a conventional loan at, say, 9.0% without a guarantee fee, you can see if the SBA loan's lower interest rate truly offers a better overall deal.
