How loan payments are calculated
A fixed-rate installment loan spreads principal and interest across equal scheduled payments. Early payments usually contain more interest because the outstanding balance is larger.
As the balance falls, less interest accrues each month and more of the regular payment goes toward principal. The amortization schedule shows that change payment by payment.
Extra principal payments reduce the balance sooner. When the lender applies them without a prepayment penalty, they can lower total interest and shorten the payoff period.
What the results can help compare
Different loan terms
Compare shorter terms with higher monthly payments against longer terms with more total interest.
Interest-rate offers
Test lender quotes with the same amount and term to see how APR affects the payment and total cost.
Extra payments
Estimate how recurring additional principal may reduce interest and accelerate payoff.
Borrowing budgets
Adjust the loan amount until the estimated payment fits your planned monthly budget.
Frequently Asked Questions
Is the Loan Calculator free?+
Yes. You can calculate loan payments and download the amortization schedule without creating an account.
Are my loan details uploaded?+
No. The calculations happen locally in your browser, so the values remain on your device.
How is the monthly payment calculated?+
The calculator uses the standard fixed-rate amortization formula based on the principal, monthly interest rate, and number of payments.

No. The result covers principal and interest only. Add lender fees, taxes, insurance, and other costs separately when evaluating an actual offer.
What happens when I add an extra monthly payment?+
The extra amount is applied to principal in the estimate, reducing the outstanding balance, total interest, and potentially the payoff time.
Can I use months instead of years?+
Yes. Switch the loan-term control between years and months.
Can I export the amortization schedule?+
Yes. Use Download CSV to save every estimated payment, including principal, interest, extra payment, and remaining balance.
