Home Loan EMI Calculator

What is a home loan EMI calculator?

A home loan EMI calculator works out the fixed monthly instalment (EMI) you pay a bank or housing finance company to repay a housing loan over its tenure. Enter the loan amount, the annual interest rate and the tenure, and this home loan EMI calculator instantly shows the EMI, the total interest you will pay, a year-by-year amortization schedule that expands into months, and how much interest a part-prepayment can save. It also estimates the income-tax deductions on home loan interest (Section 24(b)) and principal (Section 80C) for FY 2025-26 under the old tax regime.

How to use the home loan EMI calculator

1. Enter the loan amount — the amount sanctioned by the lender, not the property price. Banks usually fund 75–90% of the property value depending on the loan size.
2. Enter the interest rate — the annual rate on your sanction letter. Most Indian home loans are floating-rate loans linked to the repo rate.
3. Enter the tenure in years — from 1 to 30 years.
4. Add a prepayment (optional) — choose a one-time lump sum or an annual prepayment, the amount, and the EMI number with which it is paid. The calculator keeps the EMI unchanged and shortens the tenure, which is what most lenders do by default.
5. Pick your tax slab to see the approximate tax saved in the first year.
6. Read the schedule — click any year to expand its 12 months, or download the full month-by-month schedule as a CSV file for Excel or Google Sheets.

Home loan EMI formula with a worked example

Lenders in India calculate EMIs on a monthly reducing balance:

EMI = P × r × (1 + r)ⁿ / [(1 + r)ⁿ − 1]

• P = loan amount
• r = monthly interest rate = annual rate ÷ 12 ÷ 100
• n = number of monthly instalments

Example: ₹50 lakh at 8.5% for 20 years. Here r = 8.5 / 1200 = 0.0070833 and n = 240. (1 + r)²⁴⁰ ≈ 5.4567, so EMI = 50,00,000 × 0.0070833 × 5.4567 / 4.4567 ≈ ₹43,391. Over 240 months you pay ₹1,04,13,879 in total, of which ₹54,13,879 is interest — more than the loan itself. The split bar shows principal at 48.0% and interest at 52.0% of everything you pay.

Each month, interest is charged on the outstanding balance and the rest of the EMI reduces the principal. In the first year of this example you pay ₹4,21,182 as interest and only ₹99,511 as principal, leaving ₹49,00,489 outstanding after 12 EMIs.

How prepayment cuts your interest

A prepayment goes straight to principal, so every later month is charged interest on a smaller balance. Using the same ₹50 lakh, 8.5%, 20-year loan:

• One-time ₹5 lakh with EMI no. 12: total interest falls to ₹38,10,188 — a saving of ₹16,03,691 — and the loan closes in 192 months instead of 240, i.e. 48 months (4 years) earlier.
• ₹1 lakh every year from EMI no. 12: interest falls to ₹35,58,489, saving ₹18,55,389, and the loan closes in 168 months, 72 months (6 years) earlier.

The earlier you prepay, the larger the saving, because more of the remaining tenure benefits from the lower balance. Under RBI directions, banks and housing finance companies cannot charge foreclosure or part-prepayment penalties on floating-rate home loans taken by individuals for non-business purposes; fixed-rate loans may carry a charge, so check your loan agreement.

Home loan tax benefits in FY 2025-26

If you file under the old tax regime and live in the house (self-occupied property):

• Section 24(b) — interest paid during the year is deductible up to ₹2,00,000. The house must be acquired or constructed within five years from the end of the financial year in which the loan was taken; otherwise the cap drops to ₹30,000. Interest paid before construction is complete is deducted in five equal instalments starting the year construction finishes, within the same overall cap.
• Section 80C — principal repaid during the year is deductible within the overall ₹1,50,000 limit that also covers EPF, PPF, ELSS, life insurance premiums and children’s tuition fees. Stamp duty and registration charges also count in the year paid. If you sell the house within five years of the end of the year you got possession, the 80C deductions claimed are added back to your income.

Under the new tax regime (Section 115BAC, the default since FY 2023-24) neither deduction is available for a self-occupied house. For a let-out property, interest is deductible from rental income without the ₹2 lakh cap, but the loss you can set off against other income is limited to ₹2 lakh in the old regime.

In the default example, the first 12 EMIs contain ₹4,21,182 of interest, so the 24(b) deduction is the full ₹2,00,000, and the ₹99,511 of principal fits inside 80C. At the 30% slab plus 4% cess, that is roughly ₹93,448 of tax saved — provided you have no other 80C investments. The tool uses the first 12 EMIs as a proxy for one financial year; your bank’s interest certificate for April–March is what you actually claim.

Tips before you take a home loan

• Compare lenders on the rate and the spread over the repo rate — the spread decides how your EMI or tenure moves when rates change.
• When floating rates rise, most lenders extend the tenure rather than raise the EMI. Ask for an EMI increase instead; a longer tenure means much more interest.
• Keep the EMI within roughly 40–50% of take-home pay including other loans; this is the range most lenders use when assessing eligibility.
• Use bonuses for prepayment early in the loan, when interest makes up most of each EMI.
• If you are a joint owner and co-borrower, each co-owner can claim the 24(b) and 80C limits separately on their share.

Limitations and notes

The calculator assumes a fixed rate for the whole tenure and EMIs that start one month after full disbursement. Floating rates change over time, under-construction properties are disbursed in stages with pre-EMI interest, and processing fees, insurance and other charges are not included. Monthly figures are rounded to the nearest rupee for display only; all internal calculations use full precision. Tax figures are estimates, not tax advice.

Frequently Asked Questions

What is the EMI for a ₹50 lakh home loan at 8.5% for 20 years?

The EMI is about ₹43,391 per month. Over 240 months you pay ₹1,04,13,879 in total, of which ₹54,13,879 is interest.

Is it better to reduce EMI or tenure after a prepayment?

Reducing the tenure saves more interest because the EMI stays the same and the loan closes earlier. Reducing the EMI eases monthly cash flow but saves less. This calculator shows the reduce-tenure option, which is the usual default.

How much tax can I save on a home loan in FY 2025-26?

Under the old tax regime, for a self-occupied house you can deduct up to ₹2,00,000 of interest under Section 24(b) and up to ₹1,50,000 of principal under Section 80C (shared with other 80C investments). These deductions are not available for a self-occupied house under the new tax regime.

Do banks charge a penalty for prepaying a home loan?

RBI rules do not allow banks and housing finance companies to charge foreclosure or part-prepayment penalties on floating-rate home loans taken by individuals for non-business purposes. Fixed-rate loans may carry a charge, so check your loan agreement.

Why is most of my early EMI going towards interest?

Interest is charged on the outstanding balance, which is highest at the start. In the first year of a ₹50 lakh, 8.5%, 20-year loan, about ₹4.21 lakh of the ₹5.21 lakh paid is interest and only about ₹0.99 lakh reduces the principal.

Can I download the amortization schedule?

Yes. Click Download schedule (CSV) to save the month-by-month schedule, including any prepayments, and open it in Excel or Google Sheets. The file is created in your browser.
