A home loan is usually the largest and longest loan you will take, so the choice of EMI and tenure has a big effect on total interest. A longer tenure lowers the EMI but increases the interest you pay over the life of the loan.
Key takeaways
- EMI depends on loan amount, interest rate and tenure.
- Extending tenure from 20 to 30 years cuts the EMI modestly but can raise total interest by more than half.
- Most home loans are floating-rate; when the rate changes, banks usually change the tenure first, not the EMI.
- Part-prepayments early in the loan save the most interest.
EMI vs tenure — an example
Loan of ₹50 lakh at 8.5% a year:
| Tenure | EMI | Total interest | Total paid |
|---|---|---|---|
| 15 years | ₹49,237 | ₹38.6 lakh | ₹88.6 lakh |
| 20 years | ₹43,391 | ₹54.1 lakh | ₹1.04 crore |
| 25 years | ₹40,261 | ₹70.8 lakh | ₹1.21 crore |
| 30 years | ₹38,446 | ₹88.4 lakh | ₹1.38 crore |
Going from 20 to 30 years reduces the EMI by about ₹5,000 but adds roughly ₹34 lakh of interest.
How to choose your EMI
- Keep total EMIs (including the home loan) within about 40–50% of take-home pay.
- Keep an emergency fund of at least 6 months of expenses plus EMIs.
- Choose the shortest tenure you can comfortably afford, then plan prepayments.
- Consider future income growth — a step-up approach (increase EMI or prepay as income rises) works well.
Floating rates and the repo rate
Most bank home loans are linked to an external benchmark such as the RBI repo rate (EBLR). When the repo rate changes, your rate changes at the next reset. Banks typically increase or decrease the tenure to keep the EMI constant, which can quietly extend your loan. Ask your bank to adjust the EMI instead if you want to finish on time.
Prepayment strategy
- Individual borrowers on floating-rate home loans do not pay prepayment penalties.
- Prepay early — interest is highest in the first years.
- Choose "reduce tenure" rather than "reduce EMI" to save the most interest.
Example: a one-time prepayment of ₹2 lakh in year 2 on the ₹50 lakh, 20-year loan above can cut the remaining tenure by about 19 months.
Tax benefits (old regime)
- Principal repayment: within the ₹1.5 lakh limit (Section 80C / Section 123 of the Income-tax Act, 2025).
- Interest on a self-occupied house: up to ₹2 lakh a year.
These deductions are not available on a self-occupied house under the new tax regime. See Old vs new tax regime.

Your action checklist
- Check your credit report and fix errors at least a month before applying.
- Get the Key Fact Statement (KFS) with APR from at least two lenders.
- Keep total EMIs within about 40–50% of take-home pay.
- Read prepayment, foreclosure and penal-charge clauses before signing.
- Save the sanction letter, KFS and repayment schedule; collect the no-dues certificate when you close.
FAQs
Should I choose the longest tenure for a lower EMI?
Only if cash flow is tight. Otherwise choose a shorter tenure or plan regular prepayments.
Can I change my tenure later?
Yes, most banks allow tenure changes on request or through prepayment.
Fixed or floating rate?
Floating rates are more common and have no prepayment penalty for individuals; fixed rates offer certainty but are usually higher.
