How the formula works

Payment = P × r × (1 + r)n / [(1 + r)n − 1]
  • P = Principal (loan amount)
  • r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
  • n = Tenure in months (total number of payments)
  • Each payment splits into principal and interest
  • Interest portion decreases over time; principal portion increases
