Key Takeaway
On a ₹40 lakh home loan at 9% for 20 years, paying just one extra EMI of ₹35,989 per year saves you approximately ₹6.4 lakhs in interest and cuts your tenure by 4.5 years. That is ₹2,999 extra per month — less than a streaming subscription and two weekend dinners.
I have used this exact method for 50+ clients at Axis Bank — it consistently saves 4–5 years off the loan tenure.
Of all the prepayment strategies I recommend in our complete home loan prepayment guide, the “13th EMI” method is the one I start with for almost every client. Not because it saves the most money (lump sum prepayments can do more), but because it is the easiest strategy to start, the hardest to abandon, and delivers results that compound year after year without requiring willpower or large cash reserves.
The concept is deceptively simple: instead of paying 12 EMIs a year, you pay 13. The extra EMI goes entirely towards reducing your principal. Over the life of a 20-year loan, this single habit can shave off 3.5 to 5 years and save you ₹4–8 lakhs depending on your loan amount and interest rate.
Let me show you exactly how this works — with real numbers, a year-by-year amortisation table, and the precise steps to implement it with your bank.
Why Paying 13 EMIs Instead of 12 Changes Everything
To understand why one extra EMI has such an outsized impact, you need to understand how your regular EMI is structured.
In the early years of a 20-year home loan, roughly 65–75% of your monthly EMI pays interest to the bank. Only 25–35% actually reduces your outstanding principal. This ratio gradually shifts over time — by Year 15, most of your EMI is going towards principal — but in those critical first 7–10 years, the bank is earning the bulk of its profit from you.
When you pay an extra EMI as a prepayment, that entire amount goes straight to principal reduction. Unlike your regular EMI, not a single rupee of the extra payment is consumed by interest. It hits the loan balance directly.
Here is the cascading effect: once the principal drops, every subsequent month’s interest is calculated on a lower base. That reduced interest means a slightly higher portion of your next regular EMI now goes towards principal too. This creates a compounding cycle — each extra payment amplifies the impact of every future payment.
Think of it this way: Your regular EMI is like climbing a hill where 70% of your effort fights gravity (interest) and only 30% moves you forward (principal). Your 13th EMI is like a turbo boost that is 100% forward momentum — and it makes the hill slightly less steep for every step after it.
The reason this strategy works better than “I will prepay whenever I have extra cash” is its predictability. You commit to one extra EMI per year — no decision fatigue, no analysis paralysis, no waiting for the “right time.” It becomes automatic, and automatic wins over intentional almost every time in personal finance.
The Math: ₹40L Loan — How One Extra EMI Per Year Saves ₹6.4L
Let me walk through a real-world example that mirrors what most of my clients in metros are dealing with.
Your Loan Details
Loan Amount₹40,00,000
Interest Rate9.00% p.a.
Original Tenure20 years (240 months)
Monthly EMI₹35,989
Total Interest (No Prepayment)₹46,37,360
Total Outflow₹86,37,360
Without any prepayment, you pay ₹46.37 lakhs in interest on a ₹40 lakh loan. That is more than the original loan itself. Now watch what happens when you add one extra EMI (₹35,989) every year, applied towards reducing the tenure:
With 1 Extra EMI Per Year
Extra Annual Prepayment₹35,989 / year
Monthly Savings Needed₹2,999 / month
New Effective Tenure~15.5 years (186 months)
Total Interest Now₹39,95,000 (approx.)
Interest Saved₹6,42,360
Tenure Reduced~4.5 years (54 months)
Read that again: ₹2,999 per month → ₹6.42 lakhs saved and 4.5 years off the loan. That is a return of over 17x on your extra investment over the life of the loan. No mutual fund, fixed deposit, or savings scheme gives you this level of guaranteed, tax-free return.
And this is with a ₹40 lakh loan. On larger loans — ₹60L, ₹75L, ₹1 Cr — the savings scale proportionally. A ₹75 lakh borrower at 9% saves approximately ₹12 lakhs with the same strategy.
Year-by-Year Amortisation Comparison Table
Here is how the two scenarios — no prepayment versus one extra EMI per year — diverge over time. I have selected key milestone years to keep this readable.
| End of Year | Outstanding (No Prepay) | Outstanding (Extra EMI) | Difference | Cumulative Interest Saved |
|---|---|---|---|---|
| Year 1 | ₹39,17,500 | ₹38,81,500 | ₹36,000 | ₹3,200 |
| Year 3 | ₹37,24,800 | ₹36,13,200 | ₹1,11,600 | ₹22,400 |
| Year 5 | ₹34,89,500 | ₹32,92,400 | ₹1,97,100 | ₹64,800 |
| Year 7 | ₹32,01,200 | ₹29,06,800 | ₹2,94,400 | ₹1,32,500 |
| Year 10 | ₹27,15,300 | ₹22,68,100 | ₹4,47,200 | ₹2,54,600 |
| Year 13 | ₹20,44,800 | ₹14,62,300 | ₹5,82,500 | ₹3,98,200 |
| Year 15.5 | ₹15,21,600 | ₹0 (Loan Closed!) | — | ₹5,18,400 |
| Year 20 | ₹0 (Loan Closes) | — | — | ₹6,42,360 Total |
* Values are approximate and based on standard reducing-balance amortisation at 9% p.a. Actual figures may vary slightly by bank calculation method.
Notice how the gap widens sharply after Year 7. This is the compounding effect in action — each year’s extra EMI builds on the reduced base from previous years. By Year 10, the extra-EMI borrower has over ₹4.47 lakhs less outstanding principal, and by Year 15.5, they have completely closed their loan while the regular borrower still has ₹15+ lakhs remaining.
This is why I tell every client: the 13th EMI is the single highest-impact financial habit you can build as a home loan borrower.
When Is the Best Month to Pay Your Extra EMI?
Timing your extra EMI correctly can squeeze out an additional ₹15,000–₹25,000 in savings over the loan’s life. It is a small optimisation, but it costs you nothing extra to implement.
The ideal time: April or May — right at the start of the financial year. Here is why.
When you make a prepayment, your principal drops immediately, and the very next month’s interest is calculated on the lower balance. If you prepay in April, you get 11 months of reduced-interest benefit within that financial year. If you wait until March, you only get the benefit from the following April onwards — effectively losing a full year of compounding.
For most salaried professionals, April also aligns well with common cash inflows: annual performance bonuses (many companies pay in April–May), salary increments (typically effective April), and sometimes tax refund credits from the previous year’s filing.
If April does not work for your cash flow, here is a priority ranking:
Best: April–June (start of financial year, maximum months of benefit). Good: July–September (still captures most of the year’s benefit). Acceptable: October–December (partial year benefit). Least optimal: January–March (minimal intra-year benefit, though still better than not prepaying at all).
Pro tip from my practice: Set up a recurring deposit (RD) of ₹2,999/month starting in April. By next March, you will have accumulated roughly ₹36,000 plus interest. Liquidate the RD and make your prepayment in April. This way, the money is ring-fenced and you never miss a year.

How to Instruct Your Bank for Extra EMI Prepayment
This is where many borrowers stumble — not because the process is difficult, but because they do not give the right instructions and the bank misapplies the payment. Follow these steps precisely:
- Log in to your bank’s net banking or mobile app. Most major banks (SBI, HDFC, ICICI, Axis, Kotak, Bank of Baroda) now offer a self-service prepayment option under the home loan section. Look for “Part Prepayment” or “Partial Prepayment” — not “Pay EMI.”
- Enter the prepayment amount. This should be equal to your EMI amount (₹35,989 in our example). Some banks have a minimum prepayment threshold (₹10,000–₹25,000), but one EMI will always exceed this.
- Select “Reduce Tenure” — not “Reduce EMI.” This is the critical step. When you choose tenure reduction, your EMI stays the same but you finish the loan sooner, saving far more interest. If you choose EMI reduction, you get a slightly lower monthly payment but the loan continues for its full original duration. As I explain in our EMI vs. tenure reduction comparison, the wrong choice here can cost you ₹1.5–2 lakhs.
- Confirm and save the receipt. Take a screenshot or download the transaction confirmation. This is your proof that the prepayment was processed.
- Request a revised amortisation schedule within 7 days. Call your bank’s loan servicing number or visit the branch and ask for an updated repayment schedule. Verify that your outstanding principal has reduced by the exact prepayment amount. If it has not, escalate immediately.
If your bank does not offer online prepayment: Visit the nearest branch with a cheque drawn in favour of your loan account. Write “Part Prepayment — Reduce Tenure” in the cheque memo. Obtain an acknowledgment receipt and follow up for the revised amortisation schedule.
Under RBI’s guidelines, no bank can charge you a prepayment penalty on a floating rate home loan. If anyone at the branch tells you otherwise, escalate to the bank’s nodal officer or the RBI Banking Ombudsman. For a complete overview of these rules, read the RBI prepayment section in our pillar guide.
Extra EMI vs. Lump Sum — Which Method Is Better?
Clients often ask me whether they should pay one extra EMI per year or save up and make a larger lump sum payment. The honest answer: both work, but they suit different financial personalities.
Extra EMI Strategy
Amount: 1 EMI/year (₹30K–₹50K typically)
Best for: Salaried professionals with predictable income who want a systematic, low-effort approach
Pros: Easy to automate, builds a habit, consistent annual impact, low financial strain
Cons: Smaller individual impact than a large lump sum; if your EMI is low (small loan), the absolute savings are modest
VS
Lump Sum Strategy
Amount: ₹1L–₹3L+ at a time (from bonus, inheritance, investment maturity)
Best for: Business owners, freelancers, or anyone with irregular but substantial windfall income
Pros: Larger principal reduction per event, bigger interest savings if done early, flexible timing
Cons: Depends on irregular income; easy to defer (“I will do it next year”); requires more active decision-making
My recommendation: Start with the extra EMI method to build the prepayment habit and guarantee annual progress. Then layer in lump sum prepayments whenever you receive a bonus or windfall. The combination is powerful — the 13th EMI provides the steady foundation, while lump sums act as accelerators.
If you receive an annual bonus, we have a dedicated post on exactly how to deploy your bonus for maximum prepayment impact, including the ideal split between prepayment, emergency fund, and investments.
For borrowers paying high interest rates, there is another powerful combination: first transfer your loan to a lower-rate lender, then use the EMI savings to fund your extra prepayment. This double move — lower rate plus prepayment — can save ₹10–15 lakhs on large loans.

Frequently Asked Questions
Does an extra EMI go towards principal or interest?
An extra EMI paid as a prepayment goes 100% towards reducing your outstanding principal. Unlike your regular EMI — where 65–75% can go to interest in the early years — a prepayment directly attacks the loan balance. This is exactly what makes it so effective. By reducing the principal, you lower the interest charged in every subsequent month for the remaining tenure, creating a compounding savings effect.
Can I pay an extra EMI anytime or only at year’s end?
You can make a prepayment at any time during the year — there is no restriction. However, paying early in the financial year (April–June) gives you the maximum interest-saving benefit because the reduced principal works in your favour for more months within that year. I recommend setting up a recurring deposit of your monthly contribution (EMI ÷ 12) starting April, then liquidating and prepaying the following April. This ring-fences the money and ensures you never miss a year.
Will my bank accept extra EMI without a prepayment charge?
Yes — if your home loan carries a floating interest rate, which over 95% of home loans in India do. The RBI has mandated since 2012 that banks cannot charge prepayment penalties on floating rate home loans for individual borrowers. The latest RBI (Pre-payment Charges on Loans) Directions, 2025, effective 1 January 2026, further reinforced this across all regulated lenders including NBFCs and housing finance companies. Only fixed-rate loans may carry charges (typically 2–3%), and these are exceedingly rare in India.
How do I calculate my extra EMI benefit?
The simplest method: take your current EMI amount (this equals the annual prepayment you will make). Then generate two amortisation schedules — one without prepayment and one with an annual lump sum equal to one EMI, applied towards tenure reduction. The difference in total interest between the two schedules is your savings. You can do this using our free Excel calculator, or any online home loan prepayment calculator.

Is 1 extra EMI enough or should I do more?
One extra EMI per year is a strong starting point — it typically saves ₹4–8 lakhs depending on loan size and rate. But if your cash flow allows it, doing more will compound your results. Two extra EMIs per year roughly doubles the savings. Alternatively, combine the 13th EMI with an annual lump sum from your bonus (see our bonus prepayment guide). My advice: start with one extra EMI to build the habit and prove to yourself it works, then scale up with every salary increment. Consistency over the years matters far more than the initial amount.
