SBA 7(a) loan calculators

Four calculators for SBA 7(a) borrowers. Nothing is saved and nothing is sent anywhere; the math runs in your browser.

Payment and amortization schedule

Enter an amount, a rate, and a term to see the monthly payment and the full schedule. SBA does not allow balloon payments on 7(a) loans, so a fixed-rate loan has to fully amortize by its maturity date. That is why the schedule always ends at a zero balance.

Debt service coverage ratio

Lenders size a 7(a) loan on cash flow first and collateral second, and SBA sets the floor rather than leaving it to the lender. Coverage has to be at least 1.15 measured as operating cash flow over debt service, on a historical or projected basis, and separately at least 1:1 on a global basis once the owner's personal obligations are counted. Start-ups and changes of ownership underwritten on projections have to reach 1.15 within two years of funding. Plenty of lenders want more than the floor, but none of them can go below it.

Refinance comparison

Compare an existing balance against a new rate and term. Watch both outputs: stretching the term almost always lowers the monthly payment while raising what you pay in total. A 7(a) loan with a maturity of 15 years or more can also carry SBA's subsidy recoupment fee if you prepay more than a quarter of the balance in the first three years, and that cost is not modeled here.

Guaranty fee

The upfront guaranty fee is charged on the guaranteed portion of the loan, not on the whole loan, which is why it is smaller than borrowers expect. SBA resets the schedule each federal fiscal year on October 1 and publishes waivers by notice, so enter the figures your lender quotes rather than trusting a number written into a web page.

What SBA actually caps

SBA does not set your rate. It sets a ceiling above a base rate, usually the Wall Street Journal Prime rate, and the tiers run by loan size: 6.5 points over base at $50,000 and under, 6.0 points from $50,001 to $250,000, 4.5 points from $250,001 to $350,000, and 3.0 points above $350,000. Those are maximums, not quotes. An earlier split that priced loans differently under and over seven years was repealed in 2022 and still shows up on a lot of sites.

Ceilings from 13 CFR 120.214(d). Fixed-rate maximums use a different set of breakpoints. Confirm anything here with your lender before you sign.

Calculators that go deeper

The four tools above are quick answers. Three questions need more room, because the arithmetic is the easy part and the rule underneath it is not.

• SBA 7(a) down payment calculator. What SBA actually requires you to inject, which is a percentage of total project cost rather than of the loan, and how much of it a seller note on full standby is allowed to cover.
• SBA 7(a) rate and fee calculator. The ceiling above plus the FY2026 upfront fee schedule, the short-maturity rate, the veteran and manufacturing waivers, and the annual service fee your lender may not pass on to you.
• SBA 7(a) business acquisition calculator. Cash to close, loan size, payment, and coverage on one screen, with the seller's discretionary earnings converted to the basis a lender underwrites.
