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.
Estimated payments on a fully amortizing loan. Actual payments vary with the lender's rate, fees, and any variable-rate resets.
| Payment # | Principal | Interest | Balance |
|---|
Debt service coverage ratio
Lenders size a 7(a) loan on cash flow first and collateral second. SBA sets no minimum DSCR of its own, so the number your lender wants is a credit policy decision, not a program rule. Most look for 1.15 or better on the business as it will operate after closing.
DSCR is net operating income divided by annual debt service. Minimum acceptable DSCR is set by the lender, not by the SBA.
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.
A longer new term can lower the monthly payment and still raise total interest. Both figures are shown for that reason. Refinancing costs and prepayment penalties are not included.
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.
SBA sets the guarantee percentage and the guaranty fee schedule by notice, and revises the fee schedule each federal fiscal year (October 1). Enter the current figures from your lender or from sba.gov. This calculator does not carry a hard-coded fee schedule, so it cannot go stale.
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.
