What a ₹20 Lakh home loan really costs
A ₹20 lakh home loan is typical for a first apartment in a tier-2 or tier-3 city, or a modest top-up on an existing property. It is one of the few loan sizes where a shorter tenure stays genuinely affordable, which can save several lakh in interest.
The table below shows the monthly EMI for a ₹20 Lakh loan at the rates lenders are realistically quoting, across every common tenure. Find your offered rate along the top and your tenure down the side.
| Tenure | 8% | 8.5% | 9% | 9.5% |
|---|---|---|---|---|
| 10 years | ₹24,266 | ₹24,797 | ₹25,335 | ₹25,880 |
| 15 years | ₹19,113 | ₹19,695 | ₹20,285 | ₹20,884 |
| 20 years | ₹16,729 | ₹17,356 | ₹17,995 | ₹18,643 |
| 25 years | ₹15,436 | ₹16,105 | ₹16,784 | ₹17,474 |
| 30 years | ₹14,675 | ₹15,378 | ₹16,092 | ₹16,817 |
Monthly EMI on a ₹20 Lakh loan, reducing-balance method.
Total interest by tenure
The EMI is only half the story. Stretching the tenure lowers the monthly figure but raises what the loan costs in total — often dramatically:
| Tenure at 8.5% | Monthly EMI | Total interest | Total repaid |
|---|---|---|---|
| 10 years | ₹24,797 | ₹9.76 L | ₹29.76 L |
| 15 years | ₹19,695 | ₹15.45 L | ₹35.45 L |
| 20 years | ₹17,356 | ₹21.66 L | ₹41.66 L |
| 25 years | ₹16,105 | ₹28.31 L | ₹48.31 L |
| 30 years | ₹15,378 | ₹35.36 L | ₹55.36 L |
What salary do you need?
Lenders generally want your total EMIs to stay within 40–50% of net monthly income. For a ₹20 Lakh loan at 8.5% over 20 years, that points to a take-home income of roughly ₹45,000–55,000 a month, assuming you carry no other significant EMIs. A co-applicant's income can be combined to improve eligibility, which is why joint applications are common.
How the EMI is calculated
- P — ₹20 Lakh, the loan amount
- r — monthly rate = annual rate ÷ 12 ÷ 100
- n — tenure in months
This is the reducing-balance method every Indian bank and housing finance company uses: interest each month is charged only on the outstanding principal, which falls with every payment.
Reducing what you pay
- Prepay in the early years. The interest share of each EMI is highest at the start, so early prepayments buy far more than late ones.
- Keep the EMI, cut the tenure. When you prepay, choosing to shorten the tenure rather than reduce the EMI saves substantially more interest.
- Negotiate or transfer. Floating-rate home loans for individuals carry no prepayment or foreclosure penalty under RBI rules, so a balance transfer to a cheaper lender is always on the table.
- Compare on the reducing-balance rate, never a flat rate — a 10% flat rate is roughly equivalent to 18–19% reducing balance.
