How are loan payments calculated?

Monthly loan payments are calculated using an amortization formula that takes into account the loan principal, the annual interest rate converted to a monthly rate, and the total number of monthly payments. Each payment covers both principal repayment and interest charges.

The amortization formula

The standard formula for calculating a fixed monthly loan payment is:

M = P × [r(1+r)n] / [(1+r)n - 1]
  • M = Monthly payment
  • P = Loan principal (amount borrowed)
  • r = Monthly interest rate (annual rate / 12 / 100)
  • n = Total number of monthly payments

Good to know

This calculator assumes a fixed interest rate and constant monthly payments (amortization schedule). Actual loan offers may include additional fees, insurance, or variable rates that affect the total cost. Always compare the APR (Annual Percentage Rate) provided by lenders.
