What is Loan Payment Calculator?

The Loan Payment Calculator estimates monthly payments for a fixed‑rate loan, plus the total paid and total interest over the loan term.

It’s useful for mortgages, car loans, personal loans, and quickly comparing different APRs or terms.

What it can calculate

  • Monthly payment - the standard amortized monthly payment.
  • Total paid - monthly payment multiplied by the number of months.
  • Total interest - total paid minus the original principal.

Notes & tips

  • APR is treated as a yearly percent rate and converted to a monthly rate.
  • If APR is 0%, the monthly payment is simply principal ÷ months.
  • This calculator assumes a fixed rate and regular monthly payments (no extra payments or fees).

FAQ

What does APR mean in this calculator?

APR is the yearly interest rate expressed as a percent. This calculator converts it to a monthly rate (APR ÷ 12) and uses standard fixed‑payment amortization.

Why is the monthly payment higher than principal ÷ months?

Because each payment includes interest plus principal. Early payments are mostly interest, and later payments are mostly principal.

How do I enter the loan term?

Enter the total number of months you will pay. For example: 3 years = 36 months, 5 years = 60 months, 30 years = 360 months.

Does this include fees, insurance, escrow, or taxes?

No. It only models principal + interest for a fixed rate. If your payment includes fees or insurance, add those on top of the monthly payment.

What if the APR is 0%?

If APR is 0%, the payment is simply principal ÷ months, and total interest is 0.

How do extra payments affect the loan?

Extra payments reduce the principal faster, which usually reduces total interest and can shorten the loan term. This calculator does not simulate extra payments, so treat results as a baseline.

Why does total interest grow a lot with longer terms?

With more months, you pay interest over a longer time, even though the monthly payment is lower. Comparing different terms is a good way to see the trade‑off between payment size and total cost.

How accurate is this compared to a bank quote?

Banks may use slightly different compounding conventions and include fees in the APR. Your exact payment can differ, but this tool is accurate for standard fixed‑rate amortized loans.
