Stop Ignoring Your Amortization Schedule: 3 Numbers That Control Your Loan Cost

Request your amortization schedule from your bank today. It is a free document they are legally obligated to provide. Then come back and read this article — because those numbers are about to show you exactly how much you’re overpaying and precisely when to act.

Every Indian home loan borrower receives an EMI notice every month. Almost none of them have ever opened their amortization schedule. This single document contains more actionable intelligence about your financial future than any other piece of paper your bank will ever send you — yet it sits unrequested in bank servers across the country.

This guide teaches you exactly how to read that document, which three columns matter most, and what your numbers are telling you to do right now.

What Is a Home Loan Amortization Schedule? (Plain Language)

An amortization schedule is a complete, month-by-month table that shows the entire life of your home loan — from your first EMI to your last. For every single month, it tells you:

How much of your EMI went toward interest
How much went toward reducing your principal
What your outstanding balance is after that payment
How much cumulative interest you’ve paid so far in total

Why does it exist? Indian banking regulations and the Reserve Bank of India’s fair lending guidelines require lenders to disclose the total cost of a loan to borrowers. The amortization schedule is the most complete expression of that cost.

How to Request Your Amortization Schedule

You are entitled to this document at no charge. Here’s how to get it from the major lenders:

SBI Home LoanLog in to your YONO app → Loans → Home Loan → Repayment Schedule. Alternatively, visit your home branch with your loan account number and request it in writing.

HDFC Bank / HDFC Ltd.Log in to hdfc.com → Loan → Repayment Details → Download Amortization Schedule. Or call the dedicated loan helpline at 1800-202-6161.

Axis BankLog in to Axis Mobile app → Loans → Select your home loan → Repayment Schedule → Download PDF. Available from the date of disbursement.

ICICI / Kotak / Other BanksAll nationalised and scheduled commercial banks are obligated under RBI guidelines to provide this on request. Email your relationship manager or visit the branch with a written request — it must be provided within 7 working days.

The Column That Most Borrowers Never Look At — Cumulative Interest Paid

When a borrower does glance at their amortization schedule, they look at the EMI column. They verify the amount matches their bank debit. Then they close the document.

The column that deserves your full attention is the cumulative interest paid column — and the reason is visceral.

Let’s ground this with a realistic example. Assume a ₹50 lakh home loan at 8.75% over 20 years. Your EMI is approximately ₹44,100 per month.

Month	EMI (₹)	Interest (₹)	Principal (₹)	Outstanding (₹)	Cumulative Interest (₹)
Month 1	44,100	36,458	7,642	49,92,358	36,458
Month 6	44,100	35,900	8,200	49,53,200	2,15,700
Month 12	44,100	35,220	8,880	49,01,400	4,29,100
Month 36	44,100	33,600	10,500	47,18,000	12,80,000
Month 60	44,100	31,200	12,900	44,60,000	20,90,000

₹2.1L

By Month 36, of the ₹12.8 lakh you’ve paid in EMIs, only ₹2.1 lakh has reduced your principal. The remaining ₹10.7 lakh went entirely to interest. Your ₹50 lakh debt is still ₹47.2 lakh.

This is not a mistake. This is how amortized loans work — and it is precisely why reading this schedule is the first step toward doing something about it.

“By the time you’ve paid a third of your EMIs, you’ve often paid less than 6% of your principal. The amortization curve is steep — and it favours the bank in the early years.”

Number 1 — Your Current Interest-to-Principal Split

Open your schedule. Find today’s row — the current month. Look at the interest column and the principal column side by side. That ratio is the most honest number your bank will ever show you.

If your EMI is ₹44,100 and the interest component in today’s row is ₹34,000, that means 77% of your payment this month is pure interest. Only 23% reduces what you owe.

Why does this matter urgently? Because every rupee of principal you prepay right now eliminates the interest that would have accrued on that rupee for the remaining tenure of the loan. In the early years, that multiplier effect is enormous — a ₹1 lakh prepayment in Year 2 can save ₹1.4–1.8 lakh in interest over the remaining loan life.

How to Find ItIn your amortization table, locate the row for the current month. The two columns labelled Interest and Principal (or Principal Repayment) in that row are your Number 1. Divide Interest ÷ EMI to get your ratio. Anything above 65% means you are in an urgently high-interest phase.

Number 2 — Your Interest Inflection Point

Scroll down your amortization schedule until you find the row where the Principal column value first exceeds the Interest column value. That row is your interest inflection point — the month your EMI flips from majority-interest to majority-principal.

For a ₹50 lakh loan at 8.75% over 20 years, this inflection point typically falls around Month 145 to 155 — roughly 12 years into the loan.

Yr 12

For most 8–9% home loans with 20-year tenure, the inflection point arrives around Year 12. Before this date, prepayment has maximum mathematical impact. After it, the leverage shrinks rapidly.

This is your mathematical deadline for high-impact prepayments. Every year you delay a prepayment before this point costs you significantly more than the same prepayment made afterward. The schedule shows you this deadline with exact precision — use it.

How to Find ItScan down the Interest and Principal columns. The inflection row is where Principal > Interest for the first time. Note the year and month. That is your personal financial deadline — mark it.

Number 3 — Your Total Remaining Interest

Find your current month’s row. Look at the Cumulative Interest column in the final row of the schedule (the last EMI). Now subtract the Cumulative Interest already paid (today’s row) from that final number.

The result is your Total Remaining Interest — the exact rupee amount you will hand over to the bank from today onward if you make no changes to your loan.

For most borrowers seeing this number for the first time, the reaction is visceral. On a ₹50 lakh loan at 8.75% where you’re 3 years in, the remaining interest you’ll pay is often ₹55–60 lakh — more than the loan itself.

₹58L+

A borrower in Year 3 of a ₹50L / 8.75% / 20-year loan has already paid ~₹12.8L in interest — and still has ₹55–60L more to pay if they do nothing. This is Number 3, and it is the strongest motivator for action.

Quick FormulaTotal Remaining Interest = (Cumulative Interest in final row) − (Cumulative Interest in your current row). Write this number somewhere visible. It is the cost of inaction.

What These 3 Numbers Tell You to Do Right Now

Your three numbers are not just informational — they map directly to a specific action depending on where you are in your loan lifecycle.

Years 1–5Prepay UrgentlyYour interest-to-principal split is at its most extreme. Every rupee you prepay now destroys the maximum amount of future interest. If you have any investable surplus — bonuses, family gifts, FD maturities — direct it here before anywhere else. Even ₹1–2 lakh per year in this phase can shorten your tenure by 3–5 years and save ₹12–18 lakh in total interest.

Years 6–10Moderate Prepayment + Rate ReviewYou’re approaching the steepest part of the curve but still well before the inflection point. Prepayment remains high-value. Additionally, this window is ideal to review your interest rate — if your sanctioned rate is above current market rates, a balance transfer now has strong ROI.

Years 11–15Balance Transfer ROI Analysis + Selective PrepaymentYou are approaching or have passed your inflection point. The economics of a balance transfer require careful analysis — the stamp duty, processing fees, and legal costs must be weighed against the actual interest saving, which is now lower per month. Selective prepayment (lumpsum in the 2–3 months before the inflection point if you haven’t yet passed it) still offers meaningful savings.
Years 15+Focus on Tax OptimisationIn the final years, the interest component is relatively small and principal repayment is dominant. The primary lever here is maximising your Section 24(b) deduction (₹2 lakh on interest for a self-occupied property) and Section 80C deduction (₹1.5 lakh on principal). Consult a tax advisor about whether accelerating repayment in this phase or holding the loan longer makes better tax sense given your income bracket.
