About this helper

This calculator creates an educational fixed-rate amortization schedule. It estimates the scheduled monthly payment, each payment's principal and interest split, total interest, and remaining balance. It does not include taxes, fees, insurance, variable rates, prepayment penalties, or lender-specific rules.

Is this financial advice?

No. It is an educational estimator and does not replace a lender quote or professional financial guidance.

Are my loan numbers uploaded?

No. The schedule is calculated in your browser and the site does not receive the amounts you type.

Does the schedule include extra payments?

Yes. Add an optional extra monthly payment to estimate a faster payoff, but real lenders may apply extra payments differently.
