Understand your loan
How a Home Loan EMI is calculated
A home loan is usually the largest and longest loan you'll take — often 15 to 30 years. Even a small change in interest rate or tenure can swing the total interest by lakhs of rupees, so it pays to model it carefully before you sign.
What is an EMI?
On a home loan, the EMI (Equated Monthly Instalment) is the fixed amount you pay your bank or housing-finance company every month — usually for 15 to 30 years — until the loan is cleared. Each instalment splits into principal (the money you borrowed) and interest (the lender's charge), and because a home loan is so large and long, even a 0.25% rate difference can swing the total interest by lakhs of rupees.
The EMI formula
Banks and NBFCs in India use the reducing-balance method. The standard formula is:
Over a 20- or 30-year home loan the early-years split is striking: at first almost all of each EMI is interest, and only later does the principal fall quickly. That is exactly why prepaying in the early years — when the outstanding principal is highest — removes the most future interest.

Tips to keep your EMI affordable
- Make a larger down payment to reduce the principal and your EMI.
- Compare floating rates across banks — even 0.25% lower saves a lot over 20 years.
- Use annual bonuses for part-prepayments; floating-rate home loans have no prepayment penalty.
- A higher CIBIL score (750+) helps you negotiate a lower rate.
Home loan specifics in India
A few things are unique to home loans and change what your EMI really costs:
- Loan-to-value: banks fund about 75–90% of the property value; you pay the rest as a down payment, plus stamp duty and registration from your own pocket.
- Floating, repo-linked rates: most home loans track the RBI repo rate (EBLR), so your EMI moves with the benchmark — see how the repo rate changes your EMI and fixed vs floating.
- No prepayment penalty: the RBI bars foreclosure charges on floating-rate loans for individuals, so part-prepayments are free — and most effective early. See reduce EMI or tenure?
- Tax breaks: up to ₹1.5 lakh on principal (Section 80C) and ₹2 lakh on interest (Section 24b) under the old regime — full tax-benefit guide.
