Formula Explanation
How this calculator works

The monthly payment for a loan is calculated using the following formula:

M = P [ r(1+r)^n ] / [ (1+r)^n - 1 ]

Where:

  • M = Monthly payment
  • P = Principal (loan amount)
  • r = Monthly interest rate (annual rate divided by 12 and converted to decimal)
  • n = Total number of payments (loan term in years × 12)

The total interest paid over the life of the loan is calculated by:

Total Interest = (Monthly Payment × Number of Payments) - Principal
