What Happens to Your Home Loan When Interest Rates Change
Floating-rate home loans move with the market. See how a rate rise or cut changes your tenure or EMI — and what you can ask your lender for.
Most home loans in India are on floating rates, which means your interest rate can change during the loan. When it does, either your EMI or your tenure has to change too. Here is how that works, and what it costs.
Why floating rates move
Since October 2019, RBI rules require new floating-rate retail loans from banks to be linked to an external benchmark — most commonly the RBI repo rate. Your rate is the benchmark plus a spread set by your lender, and it must be reset at least once every three months. When the repo rate rises or falls, your loan rate usually follows at the next reset. Housing finance companies set rates using their own benchmarks, which also move with market conditions.
Two ways a lender can adjust your loan
- Keep the EMI, change the tenure. This is the most common default. When rates rise, more of each EMI goes to interest, so it takes longer to repay the principal.
- Change the EMI, keep the tenure. Your EMI goes up when rates rise (and down when they fall), and the loan ends on the original date.
RBI guidelines issued in 2023 require lenders to explain the impact of a rate reset to borrowers and to offer choices such as increasing the EMI, extending the tenure or a combination of both, along with the option to switch to a fixed rate where available.
A worked example
Consider a ₹50 lakh, 20-year loan taken at 8.5%, with an EMI of ₹43,391. After two years the outstanding balance is about ₹47,92,181 and 216 EMIs remain. Now suppose the rate changes:
| New rate | Keep EMI: remaining EMIs | Keep tenure: new EMI |
|---|---|---|
| 8.0% (cut) | about 201 (15 fewer) | ₹41,930 |
| 9.0% (rise) | about 236 (20 more) | ₹44,876 |
| 9.5% (rise) | about 264 (48 more) | ₹46,384 |
A 1 percentage point rise adds four years to the loan if the EMI is held constant — and remaining interest grows from about ₹45.8 lakh to roughly ₹66 lakh. Accepting a higher EMI instead (₹46,384) limits remaining interest to about ₹52.3 lakh.
What this means for you
- When rates rise, extending the tenure keeps your budget unchanged but can be expensive. If you can afford it, raising the EMI — even partly — saves a lot of interest.
- When rates fall, keeping your EMI unchanged lets the loan finish sooner and saves the most interest.
- Watch your age at maturity. Repeated tenure extensions can push the end date close to or beyond retirement.
- Review your spread. If your lender’s spread is high compared with new borrowers, ask about converting to a lower spread or consider a balance transfer, after accounting for fees.
Model it yourself
Enter your outstanding balance, the new rate and your remaining months in the Loan Repayment Calculator to see the new EMI and schedule. To see how many months a fixed EMI will take at the new rate, use the Home Loan EMI Calculator and adjust the tenure until the EMI matches what you pay today.
