How EMI is calculated
EMI stands for Equated Monthly Instalment, the fixed amount you pay your lender each month until the loan is cleared. Each payment covers some interest and some principal. Early on most of it is interest; later most of it is principal.
The formula is EMI = P × r × (1+r)n / ((1+r)n − 1), where P is the loan amount, r is the monthly rate (annual rate ÷ 12 ÷ 100) and n is the number of months.
Worked example
On a ₹50,00,000 home loan at 8.5% for 20 years, the monthly rate is 0.7083% and n is 240. The EMI works out to about ₹43,391, and you repay roughly ₹54.1 lakh in total, of which ₹4.1 lakh is interest.
Ways to reduce your EMI
- Make a bigger down payment so you borrow less.
- Choose a longer tenure. EMI drops, but total interest rises.
- Compare rates across banks and negotiate, especially with a good credit score.
- Prepay part of the principal whenever you have spare cash.
Frequently asked questions
Is a lower EMI always better?
No. A lower EMI usually means a longer tenure, which increases the total interest you pay. Pick the shortest tenure you can comfortably afford.
Does this include processing fees or insurance?
No. The calculator covers principal and interest only. Ask your lender about processing fees, insurance and other charges.
Are the results exact?
They are close estimates based on a fixed rate. Your lender's figure may differ slightly because of rounding, floating rates or the disbursal date.
