Most fixed-rate business term loans use amortization. Each payment includes interest on the remaining balance plus principal. Early payments often include more interest; later payments shift toward principal as the balance decreases.
APR is the annual rate used to compute a periodic interest rate. Fees can increase the true cost of borrowing. That’s why we show both standard totals and an estimated effective APR when fees are included.
Extra payments typically reduce total interest and shorten payoff time. Some loans charge prepayment penalties, so confirm your lender’s rules before assuming savings.
This calculator estimates your payment amount, total interest, total repayment, payoff timeline, and a detailed amortization schedule based on your loan amount, interest rate (APR), term, fees, and extra payments.
For the best estimate, enter the loan amount, APR, term length, payment frequency, and any origination fee. Add an optional extra payment to see how faster payoff reduces total interest.
By default, the payment is principal and interest and the origination fee is shown separately. You can choose to roll the fee into the loan to see a higher payment and a different effective APR.
An amortization schedule is a payment-by-payment breakdown showing how much of each payment goes to interest and how much goes to principal, plus your remaining balance after each payment.
Interest is calculated each period using your periodic rate (APR divided by the number of payments per year) multiplied by the remaining balance. The rest of the payment reduces principal.
Extra payments reduce your principal faster, which usually lowers total interest and shortens the payoff timeline. The schedule updates to reflect earlier payoff when extra payment is included.
Effective APR is an estimate of the true borrowing cost when fees are considered. It is calculated by finding the interest rate that makes your payment stream match the net funds you actually receive.
Yes, this works best for fixed-rate term loans with regular payments (monthly or weekly). For variable-rate loans or products with flexible payments, use this as a strong estimate and confirm details with the lender.
