Amortization — why you pay mostly interest at the start
The amortization schedule is the most revealing table in any loan document. Most borrowers never look at it — and that's exactly what lenders are counting on.
In an amortized loan, your EMI stays fixed — but the internal split between interest and principal changes every single month. In the very first EMI, interest is charged on the full outstanding principal. As you repay, the outstanding balance slowly reduces, and so does the interest component of each subsequent EMI.
This means early EMIs are mostly interest. On a ₹50 Lakh home loan at 8.5% for 20 years, your first EMI of approximately ₹43,391 includes ₹35,417 of interest and just ₹7,974 of principal repayment — 82% goes to the bank, 18% to reducing your debt. By Year 15, this ratio has flipped.
This is why prepaying in the first 5 years of a loan saves dramatically more than prepaying in Year 15. Early prepayment attacks the principal when it's at its largest, eliminating all future interest that would have been charged on that amount — often 2–3× the prepaid amount in total savings.
Interest rates across all loan types — what to expect
Not all loans are priced equally. Secured loans (where the bank holds collateral) carry far lower rates than unsecured ones. Here's the full rate landscape in India as of 2024–25.
| Loan Type | Typical Rate (p.a.) | Rate Range | Max Tenure | Secured? | Tax Benefit |
|---|---|---|---|---|---|
| 🏡 Home Loan | 8.35–9.5% | 30 years | Yes (property) | 80C + Sec 24(b) | |
| 🚗 Car Loan | 8.5–14% | 7 years | Yes (vehicle) | EVs only (80EEB) | |
| 🎓 Education Loan | 9–14% | 15 years | Partial (degree) | Sec 80E (full interest) | |
| 💳 Personal Loan | 10.5–24% | 5 years | No | None | |
| 🏦 Loan Against Property | 9–12% | 15 years | Yes (property) | None | |
| 💰 Gold Loan | 7.5–17% | 3 years | Yes (gold) | None |
The EMI vs tenure trade-off — more visible than you think
Lenders use long tenures to make large loans look affordable. The calculator makes the true cost of that convenience impossible to miss.
The single most controllable lever in any loan is tenure. Most borrowers pick tenure based on what EMI feels comfortable — without ever looking at the total interest cost. That's exactly the wrong way to choose.
On a ₹30 Lakh home loan at 8.5%: choosing 20 years over 10 years reduces your EMI by ₹12,400/month — but costs you ₹27 Lakh more in total interest. That ₹12,400 saved on EMI gets paid to the bank instead, 27 times over.
The golden rule: choose the shortest tenure where the EMI doesn't exceed 30–35% of your net monthly income. This minimises total interest without straining monthly cash flow. As your salary grows, consider prepaying to further reduce the outstanding principal.
One extra EMI a year — cuts years off your loan
Prepayment is the most underused tool in loan management. Small, consistent prepayments early in the tenure deliver returns that beat most fixed-income investments after accounting for interest saved.
Prepaying a loan is mathematically equivalent to earning a guaranteed, risk-free return equal to your loan's interest rate — after tax and without market risk. On a home loan at 8.5%, every ₹1 Lakh prepaid in Year 2 saves approximately ₹2.2–2.6 Lakh in future interest (depending on remaining tenure). That's a 2.2–2.6× return on your prepayment.
The most practical prepayment strategy is to add one extra EMI per year — whenever you receive a bonus, LTA, or annual increment. On a ₹50 Lakh, 20-year loan at 8.5%, making one extra EMI of ~₹43,000 each year reduces your total tenure by approximately 3.5 years and saves ₹15–18 Lakh in interest.
When prepaying, always choose to reduce tenure rather than EMI (most banks offer this choice). Keeping the EMI the same while cutting tenure maximises your interest savings. Reducing EMI keeps the tenure the same and saves proportionally less.
Check your loan agreement for prepayment charges — floating-rate home loans have no prepayment penalty by RBI regulation. Fixed-rate loans (car, personal) may charge 1–5% of prepaid amount.
The 40% rule — how much EMI is too much?
FOIR (Fixed Obligation to Income Ratio) is the metric every bank uses to decide your loan eligibility. It's also the best personal rule of thumb for safe borrowing.
FOIR measures your total fixed monthly obligations as a percentage of your net monthly income. This includes all EMIs (existing loans + the new one), rent if applicable, and any other fixed commitments. Most banks in India approve loans where FOIR stays at or below 40–50%.
For personal financial safety, keep your total EMI burden below 35–40% of net take-home pay. This leaves 60–65% for living expenses, savings, investments, and emergencies. Breaching 50% FOIR means any income disruption — a job change, illness, or even a large unexpected expense — could make you miss an EMI, damaging your credit score.
Lenders may approve up to 60–70% FOIR for very high-income borrowers, but just because a bank will lend you more doesn't mean you should borrow more. The bank's risk is limited to collateral recovery; your risk is years of financial stress.

Frequently asked questions
Everything you need to know about EMIs, amortization, prepayment, and loan strategy in India.
Flat rate and reducing balance (also called diminishing balance) are two methods of calculating interest. In a flat rate loan, interest is calculated on the original principal for the entire tenure — meaning you pay the same interest component every month regardless of how much you've repaid. In a reducing balance loan (used by all banks for home, car, and personal loans in India), interest is calculated on the outstanding balance — which decreases each month as you repay principal. A flat rate of 6% is actually equivalent to a reducing balance rate of approximately 11%, which is why flat rate quotes from older NBFCs or chit funds are misleading. Always compare loans on a reducing balance basis.
This is one of the most debated personal finance questions. The mathematical answer: if your loan rate is 8.5% and you can earn 11–12% post-tax from equity SIPs over the same period, invest. If you cannot stomach equity volatility, or your rate is above 10% (personal or high-rate home loan), prepay. A balanced approach works well in practice: prepay enough to keep your FOIR comfortable and loan tenure under 15 years, while simultaneously running a retirement-focused SIP. Don't make it binary — split excess cash 50:50 between prepayment and SIP, adjusting based on rates and market conditions.
For floating-rate loans (the default for home loans in India), when the RBI raises the repo rate, your lender's base rate (MCLR or Repo-linked lending rate) rises, and your effective loan rate increases. Banks typically respond by increasing your tenure while keeping EMI constant, or increasing both. When this happens, you have options: accept the higher tenure (costs you more interest over time), increase your EMI to match the original tenure, or make a lump-sum prepayment to bring the outstanding principal down. For fixed-rate loans (car, most personal loans), the rate is locked and repo rate changes don't affect you.
Closing a loan early generally has a neutral to mildly positive effect on your CIBIL score — it demonstrates responsible repayment behaviour. However, it does reduce your active credit mix and shortens the average age of your accounts, which can cause a small temporary dip (5–15 points). This is not a reason to avoid prepaying a high-interest loan — the interest savings far outweigh any temporary credit score impact. If you plan to apply for a major loan (home loan) within 3–6 months of closing another loan, time the closure before rather than during the application process.
Lenders use FOIR to determine how much you can borrow. The general rule: your maximum allowable EMI is approximately 40–50% of your net monthly income. From there, work backward using this calculator. If your net income is ₹1 Lakh/month, your max EMI is ₹40,000–₹50,000. Enter ₹45,000 EMI, 8.5% interest, and 20-year tenure into the calculator — it implies a loan of approximately ₹49–52 Lakhs. Most banks also limit home loans to 75–85% of the property value (LTV), so the remaining 15–25% must come from you as a down payment. Use the Loan Eligibility Calculator for a precise estimate.
Yes — the calculator uses the standard reducing-balance EMI formula used by all RBI-regulated banks in India, which gives results accurate to within ₹1–2 per month due to rounding. Minor variations from lender to lender arise from: how they round the monthly rate (annual ÷ 12 vs exact calendar-day calculation), processing fees included in the disbursed amount, insurance premiums bundled with the loan, and the exact disbursement date vs first EMI date. Always ask your lender for the complete amortization schedule before signing — it must show every EMI and the principal/interest split for the full tenure.
Know the true cost before you borrow
The difference between a good loan and an expensive one is almost always in the tenure, the rate, and the prepayment strategy — not the loan amount itself. Use the calculator above to find your number, then borrow with complete clarity.
