How to estimate a loan payment

How to use it

  • Enter the loan amount.
  • Enter the annual interest rate as a percent.
  • Enter the term in years.
  • Review the estimated monthly payment and total interest.

What the formula assumes

The calculator assumes fixed monthly payments and a fixed annual interest rate. It does not include taxes, fees, insurance, or variable-rate changes.

Comparing scenarios

Try different terms and rates to see how monthly payment and total interest move. Longer terms usually lower the payment but increase total interest.

Payment formula

Monthly payment
P * r / (1 - (1 + r)^-n)
Zero-rate case
principal / payments

100,000 over 30 years at 6%

The monthly rate is 0.5% and there are 360 payments; total interest is total paid minus principal.

Loan notes

The estimate assumes a fixed annual rate and standard monthly amortization. Taxes, insurance, fees, and early payments are outside this calculation.
