SBA 7(a) loans are fully amortizing. Each monthly payment covers that month's interest plus a piece of the principal, so the balance falls a little faster every month and reaches zero at the end of the term. The calculator uses the standard amortization formula:
Monthly payment = loan amount × (monthly rate) ÷ (1 − (1 + monthly rate)−number of payments), where the monthly rate is the annual rate divided by 12.
Total interest is simply the sum of all payments minus the amount borrowed. The figures cover principal and interest only; SBA guaranty fees and closing costs are separate and vary by loan size and program.
One number worth knowing while you experiment: lenders generally look for your business cash flow to cover the new payment with room to spare, commonly a debt-service coverage ratio of at least 1.1 to 1. The SBA also changed how 7(a) small loans are underwritten in March 2026, leaning decisions further toward cash flow and away from a single credit score, so the monthly payment this tool estimates is exactly the figure that underwriting will weigh against your revenue.
SBA 7(a) loans are fully amortizing, meaning each monthly payment covers that month's interest plus a piece of the principal, and the balance reaches zero at the end of the term. The payment comes from the standard amortization formula: the loan amount, times the monthly interest rate, divided by one minus (1 + monthly rate) raised to the negative number of payments. This calculator applies that formula to the amount and rate you enter, over a 10-year term.
A fixed 10-year term, which is the standard for SBA 7(a) working capital and equipment loans. That works out to 120 equal monthly payments, with the balance fully paid off at the end.
Most SBA 7(a) loans carry a variable rate tied to the Prime rate, and the SBA caps how much a lender can add on top. The rate on any specific loan is set by the lender based on the loan size, term, and the borrower's qualifications. If you have been quoted a rate, enter that. If not, the default is a neutral illustration figure, not a quote; try a range of rates to see how sensitive the payment is.
No. The figures cover principal and interest only. SBA guaranty fees, packaging or closing costs, and any lender fees are separate and vary by loan size and program. Some of these costs can be financed into the loan, which would raise the amount you should enter.
No. It is a planning tool. The results are estimates based entirely on the numbers you enter. Approval, amounts, rates, and terms on any actual loan are set by the lender based on your qualifications.
A calculator can tell you what a payment looks like. It cannot tell you how a lender will read your file. Our team came up on the underwriting side, so we can look at your actual numbers and tell you where you stand before you spend months finding out the hard way.
All results are estimates for planning purposes only, based on the amount, term, and rate you enter. They are not an offer or commitment to lend, a rate quote, or a guarantee of approval. Approval, amounts, rates, and terms are set by the lender based on your qualifications. SBA guaranty fees and closing costs are not included.
