Rs 75 Lakh Home Loan at a 5.50 Percent Repo Rate: 20 or 25 Years?
With the RBI repo rate at 5.50 percent on October 31, 2026, this guide works through EMIs and total interest on a Rs 75 lakh home loan over 20 and 25 years at illustrative rates, the effect of a quarter point change, and a seven-step budgeting check for Bengaluru buyers.
On October 31, 2026, the Reserve Bank of India's website listed the policy repo rate at 5.50 percent, with the standing deposit facility rate at 5.25 percent and the marginal standing facility rate and bank rate at 5.75 percent. Those numbers sit at the top of a chain that ends in a Bengaluru household's monthly EMI. But the most important number on a home loan is often not the rate at all. It is the tenure, because the same loan stretched from 20 years to 25 changes the monthly payment by a few thousand rupees and the total interest by lakhs.
This guide works through the arithmetic on a Rs 75 lakh loan, the kind of figure many Bengaluru buyers of a two or three bedroom flat discuss with lenders, using illustrative interest rates. It is not a rate forecast and not a recommendation. It is a way to see the trade-off clearly before you sign.
The short answer. At an illustrative 8.25 percent, a Rs 75 lakh loan over 20 years costs an EMI of about Rs 63,905 and total interest of about Rs 78.37 lakh; over 25 years the EMI falls to about Rs 59,134, but total interest rises to about Rs 1.02 crore. A quarter point change in the rate moves the 20 year EMI by about Rs 1,182 a month. The trade-off: a longer tenure eases the monthly budget by around Rs 4,800 here, but adds roughly Rs 24 lakh in lifetime interest, so the right choice depends on your cash flow, not on the lowest EMI alone.
What are the RBI's policy rates today?
The Reserve Bank of India's home page on October 31, 2026 showed a policy repo rate of 5.50 percent, a standing deposit facility rate of 5.25 percent, a marginal standing facility rate of 5.75 percent and a bank rate of 5.75 percent. It also listed the cash reserve ratio at 3.00 percent.
For a borrower, the repo rate is the one to watch. PropNewz explained how lenders link floating home loan rates to an external benchmark and add a spread in our guide to the spread over repo. The rate you actually pay is set out in your sanction letter and key fact statement, and that is the number to use in the calculations below.
How is an EMI calculated?
Home loan EMIs use the standard reducing balance formula. If P is the loan amount, r is the monthly rate, which is the annual rate divided by 12 and by 100, and n is the number of monthly instalments, then EMI equals P times r times (1 plus r) to the power n, divided by (1 plus r) to the power n minus 1. Every figure in this article is calculated with that formula and rounded to the nearest rupee.
The formula has a practical consequence. Early EMIs are mostly interest and later EMIs are mostly principal. That is why stretching the tenure lowers the monthly payment but raises total interest: you pay interest on a larger outstanding balance for longer.
| Rs 75 lakh loan, illustrative rate | Tenure | Monthly EMI | Total interest over the loan |
|---|---|---|---|
| 7.75 percent | 20 years | Rs 61,571 | Rs 72.77 lakh |
| 7.75 percent | 25 years | Rs 56,650 | Rs 94.95 lakh |
| 8.25 percent | 20 years | Rs 63,905 | Rs 78.37 lakh |
| 8.25 percent | 25 years | Rs 59,134 | Rs 1.02 crore |
| 8.75 percent | 20 years | Rs 66,278 | Rs 84.07 lakh |
What does a 20 versus 25 year tenure really cost?
Take the 8.25 percent case. Over 20 years, 240 EMIs of about Rs 63,905 repay the Rs 75 lakh with about Rs 78.37 lakh of interest. Over 25 years, 300 EMIs of about Rs 59,134 repay the same principal with about Rs 1.02 crore of interest. The monthly saving is about Rs 4,771. The extra lifetime interest is about Rs 24 lakh.
The same pattern holds at other rates. At 7.75 percent, moving from 20 to 25 years lowers the EMI from about Rs 61,571 to Rs 56,650 but lifts total interest from about Rs 72.77 lakh to Rs 94.95 lakh. Neither choice is wrong. A longer tenure can be the safer choice if your income is uncertain, because a lower fixed outgo leaves room for shocks. A shorter tenure is cheaper if the higher EMI is comfortably within your budget.
The gap scales with the loan. At the same illustrative 8.25 percent, a Rs 50 lakh loan costs about Rs 42,603 a month over 20 years and Rs 39,423 over 25 years, with total interest of about Rs 52.25 lakh and Rs 68.27 lakh respectively. A Rs 1 crore loan costs about Rs 85,207 a month over 20 years and Rs 78,845 over 25 years, with total interest of about Rs 1.04 crore and Rs 1.37 crore. In each case the longer tenure trims the EMI by a little over 7 percent while adding roughly 30 to 32 percent to total interest.
How much does a quarter point change in the rate matter?
On the Rs 75 lakh, 20 year loan, moving from an illustrative 8.25 percent to 8.50 percent raises the EMI by about Rs 1,182 a month. If instead the lender keeps your EMI unchanged and extends the tenure, our calculation shows the loan would run about 252 months rather than 240, roughly a year longer.
That is why the choice between a higher EMI and a longer tenure after a rate change matters. PropNewz looked at the options borrowers have when rates reset in our stress test for loans from Rs 50 lakh to Rs 1.5 crore. The arithmetic above is the same logic applied to a single, common loan size.
How should a Bengaluru buyer use these numbers?
Use them to set your own limits before a lender sets them for you. Decide the maximum EMI your household can carry if one income falls or expenses rise, and work backwards to the loan size and tenure that fit. Then test the plan at a rate a little higher than the one offered, because floating rates move. Our guide on budgeting a loan amount around your EMI walks through that approach.
Two habits help once the loan is running. First, when your lender notifies a change in your rate, ask in writing whether it will change the EMI, the tenure or both, and what the new end date of the loan will be. A quiet tenure extension can add years of payments without any change in the monthly debit. Second, keep a simple schedule of your own, updated each year, showing the outstanding balance and remaining tenure. If the numbers drift from what you expected, you will notice early and can decide whether to raise the EMI or prepay, rather than discovering the change near the end of the loan.
- Note the exact rate and spread in your sanction letter.
- Calculate the EMI for both 20 and 25 year tenures.
- Compare total interest, not just the monthly figure.
- Test the EMI at a rate a quarter or half point higher.
- Keep the EMI within what your household can carry in a bad year.
- Decide in advance whether you prefer higher EMI or longer tenure on a reset.
- Revisit the numbers whenever the RBI changes the repo rate.
Can prepayment change the picture?
Yes, in the arithmetic. Because interest is charged on the outstanding balance, any amount you prepay reduces the balance on which future interest is calculated. A buyer who takes a 25 year tenure for a comfortable EMI and later prepays when cash allows can narrow the gap in total interest. The size of the saving depends on when and how much you prepay, and on your loan terms, so calculate it on your own schedule rather than relying on a rule of thumb.
Check your loan agreement and key fact statement for any conditions on prepayment before you plan around it. The calculations here assume no prepayment and a constant rate for the whole tenure, which real loans rarely have.
What do these numbers not include?
They are pure loan arithmetic. They do not include processing fees, insurance premiums, stamp duty and registration on the purchase, or any charges your lender may levy. They assume the illustrative rate stays fixed for the entire tenure, which floating rates do not. They also say nothing about which rate any particular lender will offer you. Treat them as a way to understand the shape of the trade-off, then rerun the calculation with your own sanction terms.
They also leave out tax. Any deduction you may be able to claim on home loan interest or principal would change your net cost, and the effect depends on your income, the tax regime you choose and the rules in force for the year. Check the current position with a tax adviser before you treat a tax benefit as part of the plan. The comparison between tenures in this article holds before tax either way, because both options are built on the same loan, the same rate and the same formula.
