Home Loan EMI Calculator with Prepayment
Calculate your home loan EMI and see exactly how much interest and tenure you can save with prepayments. Enter your loan amount, interest rate, and tenure, then add optional prepayments — one-time, yearly, or monthly — to compare total interest with and without extra payments. The calculator shows a detailed year-wise amortization schedule with principal paid, interest paid, prepayment amounts, and ending balance. All calculations run in your browser — your loan details are never stored or transmitted.
Uses the standard reducing-balance EMI formula. Prepayment simulation assumes constant EMI with tenure reduction. Last updated: April 2026. Verify prepayment terms with your lender's sanction letter before making extra payments.

How Home Loan EMI Works
A home loan EMI (Equated Monthly Installment) is the fixed monthly payment you make to repay your housing loan. Each EMI has two parts: principal repayment (reducing the borrowed amount) and interest payment (the cost of borrowing). In the early years, 70-80% of your EMI goes toward interest. As the loan matures, the proportion shifts — by the final years, most of your EMI reduces the principal.
This calculator uses the standard reducing-balance formula: EMI = [P × r × (1+r)n] / [(1+r)n − 1], where P is loan principal, r is monthly interest rate, and n is total months. This is the same formula used by all major banks and housing finance companies worldwide.
Why prepayment is powerful
When you make a prepayment (extra payment beyond your regular EMI), it goes directly to principal reduction. This immediately reduces the outstanding balance on which future interest is calculated. The result: every rupee (or dollar) of prepayment saves you multiple rupees in interest over the remaining tenure. Early prepayments save the most because interest accrual is highest in the first half of the loan.
Home Loan Prepayment: Complete Guide
How prepayment reduces interest
When you prepay, the bank applies the extra amount to your outstanding principal. Since interest is calculated on the remaining balance, reducing principal immediately lowers the interest charged in every subsequent month. The EMI stays the same, but because less goes to interest, more goes to principal — creating a compounding effect that shortens your loan significantly.
Worked example: ₹50 lakh loan, 8.5%, 20 years
| Scenario | Monthly EMI | Total interest | Tenure | Interest saved |
|---|---|---|---|---|
| No prepayment | ₹43,391 | ₹54.14 lakh | 20 years (240 months) | — |
| ₹1 lakh yearly prepayment | ₹43,391 | ₹42.8 lakh | ~16.5 years | ~₹11.3 lakh |
| ₹10,000 monthly prepayment | ₹43,391 | ₹37.2 lakh | ~14.5 years | ~₹16.9 lakh |
| ₹5 lakh one-time (year 3) | ₹43,391 | ₹47.6 lakh | ~18 years | ~₹6.5 lakh |
Key insight: A modest ₹10,000/month extra payment on a ₹50 lakh loan saves nearly ₹17 lakh in interest and finishes the loan 5.5 years early. Enter your exact numbers in the calculator above to see your personal savings.
When to prepay vs when to invest
Prepay your home loan when: your loan interest rate exceeds the after-tax return you can reliably earn on investments. For example, if your home loan charges 9% and your post-tax investment return is 7%, prepaying gives you a guaranteed 9% "return" by avoiding that interest. However, if you can earn 12-14% in equity SIPs over 10+ years, investing may build more wealth than prepaying — but with market risk.
Use our SIP Calculator to estimate investment returns and compare against the interest saved from prepayment. The optimal strategy often combines both: maintain SIP investments while making moderate annual prepayments.
Prepayment penalties
In India, RBI mandates that floating-rate home loans for individuals have zero prepayment penalty. Fixed-rate loans may carry a 2-3% penalty on the prepaid amount — check your sanction letter. Internationally, mortgage prepayment penalties vary by lender and country. Some mortgages have "prepayment privilege" allowing 10-20% annual prepayment without penalty.
Home Loan Interest Rates: What to Expect
Interest rates vary by country, lender, credit profile, and economic conditions. Here's a reference for common ranges:
| Country/Region | Typical rate range (2026) | Loan term | Key factor |
|---|---|---|---|
| India | 8.25% – 9.5% | 15 – 30 years | Linked to RBI repo rate (EBLR/RLLR) |
| United States | 6.0% – 7.5% | 15 or 30 years | Fixed-rate dominant, linked to Fed funds rate |
| United Kingdom | 4.5% – 6.5% | 25 – 35 years | Fixed 2-5 year intro, then variable |
| Canada | 5.0% – 6.5% | 25 years amortization | Renewed every 5 years typically |
| Australia | 6.0% – 7.0% | 25 – 30 years | Variable rate common |
| UAE | 4.0% – 6.0% | 25 years max | Linked to EIBOR |

How Much Home Loan Can You Afford?
Banks approve loans based on your income, but approval doesn't mean affordability. Here are standard guidelines:
EMI-to-income ratio
- Below 30%: Comfortable — leaves room for savings, investments, and emergencies
- 30-40%: Manageable but tight — limited financial flexibility
- 40-50%: Stressful — any income disruption becomes a crisis
- Above 50%: Most financial advisors strongly advise against this

Tax Benefits on Home Loans
India
Indian homeowners can claim two tax deductions on home loans under the old tax regime:
- Section 24(b): Deduction on interest paid — up to ₹2,00,000/year for self-occupied property. This reduces your taxable income, not your tax directly
- Section 80C: Deduction on principal repaid — up to ₹1,50,000/year (shared limit with ELSS, PPF, EPF, etc.)
- Section 80EEA: Additional ₹1,50,000 for first-time buyers (on qualifying affordable housing — verify current eligibility)
Prepayment trade-off: Prepaying reduces future interest, which reduces future Section 24(b) deductions. However, you save real interest (money leaving your pocket) while losing a tax deduction (which only saves you the marginal tax rate on that interest). In most cases, prepaying is still financially better — but model it with our Income Tax Calculator.
Other countries
United States: Mortgage interest is deductible for itemizing taxpayers (up to $750,000 loan). United Kingdom: No mortgage interest deduction for owner-occupied homes. Canada: Mortgage interest is generally not deductible for primary residences. Tax rules vary — consult a local tax professional for your jurisdiction.
Choosing the Right Home Loan Tenure
Tenure choice dramatically impacts both monthly EMI and total interest. Here's the trade-off for a ₹50 lakh (or equivalent) loan at 8.5%:
| Tenure | Monthly EMI | Total interest | Total paid |
|---|---|---|---|
| 10 years | ₹61,960 | ₹24.35 lakh | ₹74.35 lakh |
| 15 years | ₹49,236 | ₹38.62 lakh | ₹88.62 lakh |
| 20 years | ₹43,391 | ₹54.14 lakh | ₹1.04 crore |
| 25 years | ₹40,261 | ₹70.78 lakh | ₹1.21 crore |
| 30 years | ₹38,447 | ₹88.41 lakh | ₹1.38 crore |
Going from 20 to 30 years reduces EMI by only ₹4,944/month but adds ₹34.27 lakh in total interest. The sweet spot for most borrowers is 15-20 years — short enough to limit interest but long enough to keep EMI manageable. A powerful strategy: take a 20-year loan but make voluntary prepayments to finish in 14-16 years.
Frequently asked questions
Does prepayment always reduce tenure?
This tool assumes the lender keeps your EMI fixed and applies extra principal to shorten the remaining tenure—a common option offered by major banks for floating-rate retail home loans. Some banks may instead reduce your EMI while keeping tenure similar, which changes the savings profile. Your sanction letter and loan agreement specify whether part prepayment retires principal against tenure or EMI. If you are uncertain, ask your loan officer before modeling aggressive prepayment schedules.
Why does tenure drop sharply after a large prepayment?
Large principal reductions immediately remove a chunk of balance that would otherwise accrue interest every month until maturity. The amortization math therefore jumps forward by many months or years in a single step until rounding and the remaining balance settle into a new schedule. Early in the loan this effect is especially dramatic because interest accrual per month is high relative to principal paid by EMI. It is normal to see a sudden drop in displayed remaining tenure after a big prepayment compared with small incremental payments.
Is EMI recalculated after prepayment here?
No. This simulation keeps the initial EMI constant for the entire payoff path whenever prepayments are applied, which aligns with many same-EMI shorter-tenure workflows. Some lenders re-amortize and issue a new lower EMI after each partial prepayment instead. If your bank follows that rule, our tenure and interest-saved numbers will not match your actual statement. Re-enter your remaining balance and revised tenure after any bank-led re-amortization to approximate reality.
Does this handle floating interest rates?
The schedule engine assumes one constant annual interest rate from start to closure for simplicity. When your floating rate resets after MCLR or repo-linked repricing, you should update the rate and re-run to approximate forward months. In practice floating loans can also change tenure or EMI depending on lender policy at reset. Treat each run as a snapshot under the current entered rate rather than a contractual forecast.
Are tax deductions modeled?
No. Home loan tax interactions—such as Section 24(b) interest caps, Section 80C principal interactions, co-borrower splits, and let-out property rules—are not built into this repayment engine. The calculator focuses on principal, interest, and prepayment cash flows only. Use an income-tax tool or Chartered Accountant to estimate post-tax affordability after deductions. Prepays still reduce actual interest paid even when they change future deduction headroom.
How is this different from the EMI calculator?
The standalone EMI page solves a classic reducing-balance loan without optional prepayment streams and is ideal when you only need a baseline amortization. This page layers optional prepayment frequency, quiet period timing, and before/after comparisons with a year-wise schedule including prepay columns. Choose the EMI page for the simplest schedule export mindset; use this page when you want to stress-test extra principal strategies.
Are loan details uploaded?
No. All mathematics execute locally in your browser; loan amount, rate, and prepayment inputs are not uploaded to DoItSwift or third-party servers for this tool path. Closing your session clears unsaved form values on your device. Shared computers may retain history in the browser cache—clear it if you are privacy sensitive.
How much interest can I save by prepaying my home loan?
It depends on your loan amount, rate, and prepayment timing. As a rough guide: on a ₹50 lakh loan at 8.5% for 20 years, a ₹1 lakh annual prepayment saves approximately ₹11 lakh in interest and finishes the loan 3.5 years early. Monthly prepayments save more because they reduce principal more frequently. Use the calculator above with your exact numbers — enter different prepayment amounts and frequencies to compare scenarios.
Should I prepay my home loan or invest in SIP?
Compare your loan interest rate with your expected after-tax investment return. If your home loan is at 8.5% and you expect equity SIPs to return 12% over 10+ years, investing theoretically builds more wealth — but with market risk and no guarantee. Prepaying gives a guaranteed "return" equal to your loan rate by eliminating that interest. A balanced approach: maintain core SIP investments while making moderate annual prepayments from bonuses or windfalls. Use our SIP Calculator to estimate investment growth for comparison.
What is the best time to make a home loan prepayment?
The earlier, the better. In the first 5-7 years of a long-tenure loan, 70-80% of your EMI goes to interest. Prepaying during this period removes principal that would have accrued decades of interest. A ₹5 lakh prepayment in year 2 saves significantly more than the same prepayment in year 15. The amortization table above shows why — early years have much higher interest components.
