A Seasoned Indian's Guide to Home Loan Prepayment Strategy

When you have lived through a few rate cycles and watched banks shift policies, you learn one thing about home loans: interest is beaten by time, timing, and steady discipline. Prepayment is that discipline. Done right, it can shave years off your loan and save you lakhs in interest, while keeping your tax position and liquidity intact.

1) First principles: what prepayment actually does

Prefer tenure reduction over EMI reduction. Every rupee you prepay early cuts future interest the most when the bank shortens tenure. Your monthly cash flow stays the same, and the interest saved compounds.

Interest is calculated on the daily outstanding, while EMI is monthly. Prepay as early in the month as your bank will credit it to principal. Ask for the cut‑off time so the money does not sit in a suspense account.

For floating‑rate home loans for individual borrowers, banks should not levy prepayment or foreclosure penalties. Fixed‑rate loans can have conditions and charges. Always check your sanction letter and current schedule of charges.

2) Know your benchmark: EBLR or MCLR

EBLR or RLLR, which is repo linked, resets quickly and transmits policy moves faster. You feel cuts sooner, and hikes sooner as well.

MCLR resets more slowly. It can lag in falling cycles and feel gentler in rising ones.

How this affects prepayment: If you are on MCLR in a falling cycle, consider paying a small conversion fee to shift to EBLR. If the cycle is rising or volatile, MCLR can cushion spikes. Regardless of benchmark, earlier prepayment always wins.

Pro move: Ask your bank for your current benchmark, spread, and next reset date during your annual review. This tells you exactly how rate changes will hit your EMI.

3) Taxes: align prepayment with deductions

Two sections matter for most salaried buyers.

Section 24(b), interest on housing loan
Up to ₹2 lakh per year for a self‑occupied property under the old regime. Under the new regime, many deductions are not available. Unused loss from house property can be carried forward for eight years, but only against income from house property.

Section 80C, principal repayment
Principal repaid counts within the ₹1.5 lakh overall limit. If you sell within five years of possession, the 80C principal benefit gets reversed. Interest deduction does not get reversed. If there is any chance of an early sale, moderate your prepayments.

Rule of thumb:
If your annual interest comfortably exceeds ₹2 lakh, accelerate prepayment. If it sits just above ₹2 lakh, prepay enough to keep interest near that level, then let time do the rest. If it is already below ₹2 lakh, go by cash flow and opportunity cost rather than tax.

4) Where the prepayment money should come from

• Use windfalls such as bonuses, RSU vesting, maturity proceeds, or rent surplus for lump‑sum part prepayments.
• Do not raid your emergency fund or retirement corpus. A 30‑year loan will not help you through a three‑month job loss.
• EPF withdrawals for housing exist, but treat them as a last resort. Retirement compounding is precious.

5) Cadence that works in real life

Quarterly micro‑prepay. Add one extra EMI each quarter, or add half an EMI every month. This quietly chops years off your tenure.

Annual EMI step‑up. Raise your EMI by 5 to 10 percent when you get an increment. Keep tenure fixed.

Milestone prepay. After a benchmark reset or a rate cut, top up with a small prepayment to lock in a shorter tenure.

6) Conversion, balance transfer, and offset accounts

Internal conversion. Many banks allow a spread reduction for a one‑time fee. Run a simple breakeven. If the fee pays back within 12 to 18 months through lower interest, convert.

Balance transfer. Make sense only when the rate gap is meaningful and you plan to hold the loan long enough to recover processing fees, valuation, legal checks, and incidental costs.

Offset or home saver accounts, for example SBI MaxGain. Your surplus sits in a linked account. Interest is charged on outstanding minus the offset balance. This keeps liquidity while lowering interest, which is ideal for variable cash flows.

7) Bank rules that often trip borrowers

Before you build a prepayment habit, confirm these points with your bank.

• No prepayment or foreclosure penalty for floating‑rate loans for individuals, including when funds come from your own sources.
• The credit date for part prepayments and the cut‑off time for same‑day principal credit.
• The minimum lot size for part prepayment. Some banks insist on at least one EMI or a fixed multiple.
• The default treatment of a prepayment. Ask for tenure reduction by default. Get a revised amortization schedule each time.
• Your benchmark, spread, reset frequency, and the next reset date.
• The conversion fee and the exact post‑conversion rate, confirmed in writing.
• The process for online prepayment, confirmation of UTR or reference number, and same‑day value.
• The closure checklist for full foreclosure. Obtain a clean NOC, an inventory of original documents, lien removal instructions for registrar or society, and the turnaround time for credit bureau updates.

8) A clean sequence to follow

1. Obtain a fresh amortization schedule and rate letter that shows balance, rate, benchmark, and reset date.
2. Review your tax position, including old versus new regime, Section 24(b) headroom, and 80C utilization.
3. Pick a lane that matches your cash flows.
   • Stable cash flows: EMI step‑up plus quarterly micro‑prepay.
   • Volatile cash flows: offset account, or small periodic prepayments while keeping a larger buffer.
4. Compare internal conversion against balance transfer with a simple breakeven. If unclear, prefer internal conversion and prepay the difference.
5. Calendarize four prepayment dates a year, for example post bonus, after tax refund, around festivals, and at annual appraisal time.
6. Review annually in your reset month. Check rate, remaining tenure, and whether another conversion is justified.

9) Copy‑paste checklist for the bank

• Please confirm that as an individual on a floating‑rate home loan I will not be charged any prepayment or foreclosure penalty, including when I prepay from my own sources.
• What is my current benchmark and spread, and what is the next reset date? Do you offer a spread reduction? What is the conversion fee and the post‑conversion rate?
• When I part prepay online, is the amount credited to principal the same day? What is the cut‑off time?
• Please set tenure reduction as the default instruction for all part prepayments and issue a re‑amortization schedule each time.
• Are there minimum lot sizes or annual limits on part prepayment?
• For full closure, list the original documents you hold and your NOC, lien release, and credit bureau update timelines.
• If I opt for your offset or home saver variant, explain how interest is computed and the operational rules.

10) About timing the cycle

Do not obsess over calling the interest‑rate bottom or top. Banks adjust at different speeds. Reset lags and your spread often matter more than a headline repo move. Use dips to convert or to prepay, but keep the habit even when news is noisy.

Pro move: Set calendar reminders for your reset dates and rate review meetings. Being systematic beats trying to time markets.

11) Red flags from experience

• Banks reduce EMI by default after a prepayment, which saves less interest than tenure reduction.
• Prepayments that sit in a suspense account for days. Always check value date.
• Balance transfers for tiny rate gaps that never recover fees.
• Aggressive prepayment while carrying high‑interest unsecured debt. Clear the expensive debt first.
• Selling within five years and discovering the 80C reversal later.

Closing thought

A home loan runs for decades, while your income and priorities keep changing. Prepayment is how you keep control. Build a simple cadence, insist on tenure reduction, and use conversions with a clear breakeven. Quiet consistency will finish your loan years earlier and with far less stress.

Next Steps

Call your bank today: Ask for your current benchmark, spread, and conversion quote. Set up tenure reduction as your default prepayment instruction. Calendar quarterly prepayment dates aligned with your cash flow cycles.
