The 15, 20, 25 and 30-year comparison
This example keeps the loan amount and rate unchanged: ₹50,00,000 at 8.5% a year on a monthly reducing balance. It assumes a constant rate, regular monthly EMIs, no prepayment, no missed payments and no fees or charges.
| Tenure | Monthly EMI | Total interest |
|---|---|---|
| 15 years | ₹49,237 | ₹38,62,656 (₹38.63 lakh) |
| 20 years | ₹43,391 | ₹54,13,879 (₹54.14 lakh) |
| 25 years | ₹40,261 | ₹70,78,406 (₹70.78 lakh) |
| 30 years | ₹38,446 | ₹88,40,443 (₹88.40 lakh) |
Why a longer tenure lowers the EMI
The same principal is spread over more monthly instalments. That reduces the amount due each month, although interest continues to be charged while the balance remains outstanding.
The EMI reduction becomes progressively smaller in this example. Moving from 15 to 20 years lowers the displayed EMI by ₹5,846, while moving from 25 to 30 years lowers it by ₹1,815.
Why total interest rises
A longer tenure keeps principal outstanding for more months. Even though each EMI is lower, interest is calculated over a longer period, so the total can rise substantially.
The 30-year option in this example has a displayed EMI ₹4,945 lower than the 20-year option. Its total interest is ₹34,26,564 higher, or about ₹34.27 lakh. The monthly reduction and the lifetime increase need to be read together.
A floating rate can change the comparison
The table assumes 8.5% throughout. A floating-rate home loan may reset during its tenure, changing the EMI, the number of instalments, or both.
For applicable EMI-based floating-rate loans, RBI instructions require the regulated entity to communicate the impact of a reset and provide the applicable options. These can include a higher EMI, longer tenure, a combination, switching to a fixed rate under the lender’s policy, and part or full prepayment. The lender should not be assumed to apply one outcome in every case.
There is no single correct tenure
A shorter tenure needs a higher monthly payment but reduces the time over which interest accrues. A longer tenure lowers the required EMI but can leave less room for future rate increases and can materially raise total interest.
The suitable tenure depends on cash flow, other essential commitments and the loan terms. This comparison does not recommend one tenure for every borrower.
Compare your own amount and rate
A ₹50 lakh example cannot represent every loan. Changing the amount or rate can materially change both the EMI and the gap between tenures.
Frequently asked questions
Does the lowest EMI mean the lowest-cost tenure?
No. A lower EMI commonly comes from spreading repayment over more months, which can increase total interest. Compare both figures.
Does the table predict what a floating-rate loan will cost?
No. It holds the rate at 8.5% for the full tenure. Actual floating rates and the resulting repayment schedule can change.
