Business Loan Calculator

This calculator uses the standard amortization formula: each payment covers the interest accrued that month and puts the rest against the balance. The payment stays level, while the share going to principal grows over time. Three inputs move it — the amount, the rate, and the term — and the third is the one borrowers underestimate.

Term changes the payment more than the rate does. Stretching the same loan over twice as long can nearly halve the monthly payment, which is why longer terms feel affordable. It also keeps the balance outstanding longer, so total interest rises. The calculator shows both numbers for a reason: judge an offer on the total repayment and the payment together, not on either alone.

Not every business funding product amortizes. A merchant cash advance and much revenue-based funding are priced with a factor rate and repaid through daily or weekly remittances, so there is no interest rate to enter here and no amortization schedule to follow. For those, the honest comparison is total payback in dollars and how quickly it is collected. This calculator is built for term loans and other amortizing products.

Fees sit outside the payment. Origination and closing costs, prepayment rules and any minimum finance charge change what financing costs without changing the monthly number, which is how two offers of the same size end up costing very different amounts.

Financing an SBA 7(a) or 504 project instead? The SBA loan calculator prefills the current published rate ceilings and 504 debenture pricing. To check whether the payment above is one a lender will believe your business can carry, the debt service coverage calculator adds it to what you already owe and shows the ratio underwriting will see. If you are still sizing the request, how much funding you can qualify for and what lenders require are the practical next reads.
