What is an EMI?
An Equated Monthly Instalment (EMI) is the fixed amount you pay to a lender every month until a loan is fully repaid. Each EMI has two parts: a portion that pays interest on the outstanding loan, and a portion that reduces the principal. In the early months of the loan, most of your EMI goes towards interest; in the later months it goes mostly towards the principal. This is known as amortisation.
EMI Formula
EMI = P × R × (1+R)^N / ((1+R)^N – 1)
Where P is the loan amount, R is the monthly interest rate (annual rate ÷ 12 ÷ 100), and N is the total number of monthly instalments.
How to Reduce Your EMI
You can lower EMIs by choosing a longer tenure (though this increases total interest), negotiating a lower rate by transferring the loan, making prepayments during the early years when interest is highest, or making a larger down payment up-front. Always aim to keep total EMIs below 40% of your take-home income.
Frequently Asked Questions
Does the EMI change if interest rates change?
On floating-rate loans, the EMI can change when benchmark rates (repo rate) change. On fixed-rate loans it stays the same for the agreed period.
Can I prepay my loan?
Yes. Floating-rate home loans in India have zero prepayment penalty for individuals. Prepaying in the early years saves the most interest.
Is it better to increase EMI or extend tenure?
A higher EMI saves interest. A longer tenure reduces monthly burden but increases total interest paid.
