About this tool

The Loan Calculator shows your monthly payment, total interest, and amortization schedule based on loan amount, interest rate, and term. Compare fixed-rate mortgages, auto loans, and personal loans side by side before you sign anything.

How to use

  1. Enter the loan amount you plan to borrow.
  2. Enter the annual interest rate (APR) and the loan term in years or months.
  3. Pick the payment frequency — monthly is the default.
  4. Review the monthly payment, total interest, and total repayment.
  5. Scroll through the amortization schedule to see how each payment splits into principal and interest.

Common use cases

  • Comparing offers from two lenders with different interest rates.
  • Deciding between a 15-year and a 30-year mortgage.
  • Budgeting for a car loan before visiting the dealership.
  • Estimating how much extra to pay every month to finish a loan early.
  • Understanding how much of a monthly payment goes to interest early in the loan.

Frequently asked questions

Does the calculator include taxes and insurance?

No. It computes principal and interest only. Add escrow, taxes, and insurance separately for a mortgage estimate.

Is APR the same as the interest rate?

They are close but not identical. APR includes some fees. Use the rate your lender publishes as APR for the most realistic result.

Can I model extra payments?

Yes. Add an extra monthly payment to see how much interest you save and how many months the loan shortens.

Is my loan data stored?

No. The calculator runs locally and does not send your numbers anywhere.
