Payment = P × r ÷ (1 − (1 + r)−n)
P = loan amount · r = annual rate ÷ 12 · n = years × 12. At 0%: payment = P ÷ n.
What each input means
- Term preset: a shortcut that fills the term with 10 years or 25 years. SBA 7(a) maturity generally runs longer for real estate than for working capital or equipment, and the lender sets your actual term. Review SBA rates, terms and fees.
- Loan amount: the principal you expect to borrow. Per the SBA 7(a) page, the program maximum is $5 million.
- Illustrative interest rate: enter a rate a lender quoted, or test a low, middle and high rate to see a range.
- Term: years of monthly payments. Longer terms lower the payment but raise total interest.
- Upfront fees (optional): a percentage of the loan for fees you expect at closing, shown separately so you can see them.
What the results tell you
- Estimated monthly payment: principal plus interest each month at a fixed rate.
- Total interest: interest paid over the full term if the loan runs to maturity.
- Total repaid: loan amount plus total interest.
- Upfront fees: appears when you enter a fee percentage.
- Yearly amortization schedule: how the balance falls each year.
How to use the estimate
- Compare the monthly payment with the cash flow your business has left after operating costs. The SBA notes most 7(a) term loans are repaid monthly from business cash flow.
- Test the debt service coverage the payment implies before talking with a lender.
- Run two or three rates and terms, then bring the range, not a single number, to lender conversations.
- Compare actual lender quotes with the loan fees and points calculator.
What the estimate leaves out
This fixed-rate estimate excludes future variable-rate changes, SBA guarantee fees, closing costs and prepayment terms unless entered. A preset is not an eligibility decision or loan offer.

Is this an official SBA calculator?
No. Profit Theory built this estimate tool for planning. The SBA does not set your payment; you apply through a participating lender, and that lender sets the final terms.
How is an SBA 7(a) monthly payment calculated?
For a fixed-rate, fully amortizing loan, payment = P × r ÷ (1 − (1 + r)^−n), where P is the loan amount, r is the annual rate divided by 12 and n is the number of monthly payments. The calculator applies this formula to the amount, rate and term you enter.
Will my SBA loan payment change over time?
According to the SBA, payments stay the same on fixed-rate loans, while on variable-rate loans the lender may require a different payment when the rate changes. This calculator shows a fixed-rate estimate only.
Does the estimate mean I qualify for an SBA loan?
No. The calculator does not check eligibility. The SBA lists factors such as being an operating, for-profit, U.S. small business that is creditworthy and can show a reasonable ability to repay; the lender decides.
