Home loan EMI explained: formula, example, and how to lower it
Learn how banks compute EMI, why early EMIs are interest-heavy, and what actually reduces total interest.
Open the Home loan EMI calculatorWhat is EMI?
Equated Monthly Instalment is the fixed amount you pay the lender each month. It has two parts: interest on the outstanding principal and repayment of principal. On a reducing-balance loan, the mix shifts toward principal as the balance falls.
The formula banks use
EMI = P × r × (1 + r)^n / ((1 + r)^n − 1). P is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is tenure in months. A ₹50 lakh loan at 8.5% for 20 years (240 months) has r = 0.007083 and EMI ≈ ₹43,391.
How to lower EMI or interest
A larger down payment cuts P. A better credit score can cut r. Extra EMI or prepayment cuts tenure. Use the extra-EMI calculator to see the year-by-year payoff and the interest you still pay if you send more than the contracted instalment.
