SBA 7(a) Loan Payment Calculator
Estimate your monthly payment, including the option to finance the SBA guaranty fee into your loan balance.
This is an estimate only, not a loan offer, pre-qualification, or rate quote. SBALoanPro is not affiliated with, endorsed by, or operated by the U.S. Small Business Administration. Actual rate, term, and fee treatment are set by your lender.
Methodology & Assumptions
This calculator applies a standard fixed-rate amortization formula: monthly payment = principal × monthly rate ÷ (1 − (1 + monthly rate)−months). If you choose to finance the guaranty fee, that fee is added to the loan amount before this formula runs, which raises both the principal and the resulting payment. The guaranty fee tiers shown reflect the SBA's general tiered structure for the 7(a) program's up-front fee on the guaranteed portion — but exact fee percentages and thresholds are set by the SBA for each fiscal year and can change. Always confirm the current fee schedule using the SBA's official guaranty fee calculator before relying on a number for a real application.
Worked Example
Inputs: $350,000 loan · 10.5% rate · 10-year term · fee financed into balance.
A $350,000 loan falls in the fee tier applied to loans between $150,000 and $1,000,000. With the fee added to principal, the financed balance is amortized over 120 months at 10.5%, producing a monthly payment in roughly the mid-$4,000s and total interest that typically runs 60–70% of the original loan amount over a full 10-year term — a rough rule of thumb that holds across most 7(a) rate/term combinations, though your exact figures will vary. Run your own numbers above to see the precise breakdown.
What This Calculator Doesn't Do
It doesn't check your eligibility, credit, collateral, or cash flow, and it doesn't reflect any specific lender's underwriting criteria. It also doesn't account for optional add-ons like origination or packaging fees a lender may separately charge on top of the SBA guaranty fee. Use the Debt Service Coverage Ratio Calculator as a next step to see whether your cash flow is in the range SBA lenders typically require.
Frequently Asked Questions
How does this calculator estimate my SBA 7(a) payment?
It uses a standard fixed-rate amortization formula against the loan amount, rate, and term you enter. Financing the guaranty fee adds it to principal first. This is an estimate, not a lender quote.
Should I finance the guaranty fee or pay it upfront?
Most borrowers finance it to avoid a large cash outlay at closing, accepting a slightly higher balance and payment. Paying upfront lowers the ongoing payment but requires more cash at closing.
Are SBA 7(a) rates fixed or variable in this calculator?
You can test any rate, but most real 7(a) loans are variable, tied to Prime plus a lender spread — treat this as a snapshot at today's rate.
Does this calculator check whether I qualify?
No — it only estimates a payment from the numbers you provide. Check your DSCR as a directional signal, then confirm eligibility with a lender.
