How the EMI formula works

The equated monthly installment (EMI) is calculated using the standard reducing-balance method used by every RBI-regulated Indian lender.

EMI = [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

Common EMI questions

What is EMI?+

Equated Monthly Installment — a fixed amount you pay every month until the loan is fully repaid. Each EMI includes part principal and part interest.

Can I prepay my loan to reduce EMI?+

Yes. Most Indian lenders allow part-prepayment on floating-rate loans with zero charges. Fixed-rate personal loans may carry a prepayment fee of 2–5%.

How does interest rate affect EMI?+

A 1% change in interest rate on a ₹50 lakh, 20-year home loan changes the EMI by roughly ₹3,200 per month.

Is this EMI calculator accurate for Indian lenders?+

Yes. It uses the standard reducing-balance formula followed by all RBI-regulated banks and NBFCs in India.
