Payment, interest & total cost
A business loan's monthly payment is calculated with the standard amortization formula on the loan amount, interest rate, and term. But the rate alone doesn't tell the whole story — many business loans charge an origination fee (often 1%–6%) deducted from your proceeds or added to your cost, which raises the effective cost of borrowing. This calculator shows your monthly payment, the total interest over the life of the loan, the dollar amount of the origination fee, and the all-in total cost.
For example, a $100,000 loan at 9% over 5 years has a monthly payment of about $2,076, totaling roughly $124,560 — about $24,560 in interest. Add a 3% origination fee ($3,000) and the true cost rises to about $127,560. When comparing lenders, always look past the headline rate to the fees, term, and total cost, because a lower rate with high fees can cost more than a slightly higher rate with none.
The interest rate sets your payment; fees push the effective APR higher. A 9% loan with a 3% fee behaves like a higher-rate loan once fees are counted.
Longer terms lower the monthly payment but increase total interest. Shorter terms cost less overall but strain monthly cash flow.
Commonly 1%–6% of the loan, charged upfront. Factor them in — they meaningfully change the true cost of the loan.
Make sure the monthly payment fits your business's cash flow with margin to spare before borrowing — revenue can be seasonal.
