Loan Payment and Amortization Calculator

How to use the loan calculator

Enter the requested values, review the units, and select Calculate. The result updates only after every input passes validation.

The calculator uses the standard fixed-payment amortization formula and applies interest to the remaining principal each month. Extra payments reduce principal after the scheduled payment.

Worked example

A $10,000 loan at 6% for 36 months has a scheduled payment of about $304.22 before any extra payment.

Limitations

Actual lender schedules can differ because of payment dates, daily interest, fees, and rounding rules.
