Loan paymentcalculator
Calculate monthly payments, total interest, and full amortization schedule for any loan.
Start with the base payment, then add an extra monthly payment to see how much faster the schedule closes.
It is a quick way to check whether a small overpayment meaningfully lowers total interest.

Understanding loan payment estimates
What your payment includes
A standard loan payment is made up of principal and interest. Early payments often contain more interest because the balance is larger; as the balance falls, more of each payment can reduce principal.
How term and APR affect the cost
A longer term can lower the required monthly payment but usually increases the total interest paid. A higher APR has a similar effect. Compare the monthly cost with the total cost before choosing a term.
- Loan amount: The starting principal used in the estimate.
- APR: The annual rate used to estimate monthly interest.
- Term: The planned number of monthly payments.
Check the terms before overpaying
Extra payments can shorten the projected schedule and reduce interest. Confirm how your lender applies overpayments, and check for fees or restrictions before changing your payment plan.
