Home Loan EMI Calculator
Calculate reducing-balance home loan EMI, total interest, payoff date, prepayment savings, upfront borrowing cost, income ratio, and a complete amortization schedule.
Last Updated: July 23, 2026
A home loan can run for decades, so compare more than the monthly EMI. This reducing-balance calculator estimates each payment, total interest, payoff date, fees, and the effect of regular or one-time prepayments. Enter the rate and costs from your own lender documents; the tool does not treat a temporary advertised rate as a universal offer.
Calculate Your Home Loan Repayment
The model keeps the scheduled EMI unchanged when prepayments are added and uses them to shorten tenure. It does not convert currencies or predict future floating-rate changes.
An extra monthly payment shortens this loan
The entered plan repays the loan in about 15 years 7 months, saving an estimated 53 months and ₹1,389,250 of interest versus the same loan without prepayments.
- Prepayments are modeled as tenure reduction while the EMI stays unchanged.
- Stamp duty, registration, insurance, taxes and future rate resets are excluded unless entered.

How to Use This Home Loan EMI Calculator
- Enter the amount that will actually be financed, not the property's full purchase price. The down payment is not part of loan principal.
- Select a display currency and enter the annual reducing-balance interest rate quoted for the loan. A flat rate is not comparable.
- Enter the repayment tenure in years or months and choose the first regular EMI date. The date labels the schedule; it does not calculate broken-period interest before the first EMI.
- Add the lender's processing-fee percentage and any known upfront loan costs. Keep stamp duty, registration and the down payment separate unless your purpose is to view all cash paid around borrowing.
- Optionally enter a monthly extra payment, a one-time prepayment, or both. This calculator applies extra money to principal and keeps the scheduled EMI constant, so the modeled tenure becomes shorter.
- Add household income and other monthly debt only if you want the simple payment-to-income screen. It is not a loan approval, FOIR limit, or lender-specific eligibility test.
- Review the headline EMI, interest savings, rate sensitivity, yearly totals and full monthly amortization schedule. Compare the result with the lender's Key Facts Statement and sanction letter.
All amounts must use the same currency. Choosing another symbol changes presentation only; no exchange-rate conversion occurs. Use the Copy Summary button to retain the main assumptions and outputs while comparing offers.
Home Loan EMI Formula
An equated monthly instalment combines interest on the outstanding balance with principal repayment. For a constant rate and fixed number of monthly payments, the standard reducing-balance formula is:
- P is the original loan principal.
- r is the monthly rate: annual nominal rate divided by 12 and then by 100.
- n is the total number of monthly instalments.
When the entered rate is 0%, the calculator avoids division by zero and uses principal divided by months. At a positive rate, interest is highest near the start because the outstanding balance is largest. The principal component gradually rises as that balance falls.
Worked home loan EMI example
Assume a home loan of ₹50,00,000, an annual reducing-balance rate of 8.5%, and a 20-year term. The monthly rate is 8.5% divided by 12, or about 0.7083%, and the loan has 240 scheduled payments.
- Estimated monthly EMI: ₹43,391
- Total repayment without prepayment: about ₹1,04,13,879
- Total interest without prepayment: about ₹54,13,879
- With an extra ₹5,000 every month: payoff in about 187 months
- Estimated interest with that prepayment: about ₹40,24,629
- Estimated saving: about ₹13,89,250 and 53 months
These figures use exact internal calculations and rounded display amounts. A lender schedule can differ because of daily accrual, EMI rounding, a partial first period, disbursement timing, rate resets or fees financed into the principal.
How the Amortization Schedule Works
Each schedule row begins with the previous month's closing balance. Monthly interest equals opening balance multiplied by the monthly rate. The regular principal component equals the payment minus that interest. Any entered prepayment is then applied directly to remaining principal, subject to the outstanding balance.
Regular principal = regular payment - monthly interest
Closing balance = opening balance - regular principal - extra payment
The final regular payment is capped at the amount required to clear the balance, so it may be smaller than the headline EMI. The yearly summary groups the same monthly rows by calendar year and does not invent annual payments. This makes the table useful for seeing how interest-heavy the early years are and how quickly a prepayment plan changes the balance.
Home Loan Prepayment: EMI Reduction or Tenure Reduction?
A principal prepayment can be used in two common ways. Keeping EMI unchanged generally shortens the term and saves more interest because principal remains lower for fewer months. Reducing EMI while retaining the original term improves monthly cash flow but usually leaves the loan outstanding longer. This calculator uses the first method: EMI stays constant and tenure falls.
| Prepayment treatment | Monthly cash flow | Likely interest effect | Best suited to |
|---|---|---|---|
| Keep EMI, reduce tenure | Regular EMI remains similar | Usually larger interest saving | Borrowers prioritizing faster payoff |
| Reduce EMI, keep tenure | Required EMI falls | Usually smaller saving than tenure reduction | Borrowers needing monthly flexibility |
| Occasional lump sum | No permanent extra monthly commitment | Earlier payments generally save more | Bonuses, asset sales or irregular surplus |
Do not empty an emergency fund only to create a theoretical interest saving. Check whether prepayment affects liquidity, insurance needs, retirement contributions or higher-cost debt. Also confirm the lender's minimum amount, request process, treatment choice and documentation.
Fixed vs Floating Home Loan Rates
A fixed rate offers payment certainty for the period that is genuinely fixed. A floating rate changes with the contractual benchmark and spread, so EMI, tenure or both can change. A "fixed" label may apply only for an initial period, making the reset clause important.
| Feature | Fixed rate | Floating rate |
|---|---|---|
| Payment predictability | Higher during the fixed period | Lower because benchmark resets can alter repayment |
| Benefit from falling rates | Usually requires conversion or refinance | May pass through at contractual reset dates |
| Risk when rates rise | Limited during a true fixed period | EMI, tenure or both may increase |
| What to inspect | Fixed period, reset basis and conversion fee | Benchmark, spread, reset frequency and margin |
The Reserve Bank of India's updated guidance for floating-rate EMI-based personal loans requires regulated lenders to communicate rate-reset effects. Borrowers must be offered choices around higher EMI, longer tenure, a combination, and part or full prepayment; lenders must also prevent negative amortization and provide prescribed periodic information. A fixed-rate switch may be offered under the lender's approved policy, so it should not be assumed to be automatic.
Compare APR and Total Cost, Not EMI Alone
A lower EMI can simply result from a longer tenure. That lowers the monthly obligation while potentially increasing lifetime interest. When comparing home loan offers, keep principal and term consistent, then inspect the nominal rate, Annual Percentage Rate, processing fee, legal or valuation charges, insurance, conversion costs and reset terms.
RBI's Key Facts Statement rules define APR as the annual cost of credit including interest and associated charges. For covered retail term loans, the KFS should include an APR calculation sheet and amortization schedule, and charges collected through the lender on behalf of third parties must be disclosed. This page adds entered fees to cash outflow but does not label that simplified result as APR. Use the lender's KFS for the regulated all-in comparison.
- Compare the same principal, tenure and rate type.
- Ask whether fees are deducted from disbursal, paid separately or financed.
- Check whether bundled insurance is optional and whether premium is added to principal.
- Read the benchmark, spread, reset date, conversion charge and prepayment terms.
- Request the complete repayment schedule, not only the first EMI quote.
Affordability and the Payment-to-Income Screen
The calculator's optional ratio is:
This is a budgeting indicator, not a universal lender rule. Banks may use gross or net income, FOIR, documented obligations, age, credit profile, employment type, loan-to-value limits and internal buffers. Household affordability also includes expenses a loan model cannot see: maintenance, property tax, utilities, education, health care, insurance and irregular income.
Stress-test the payment at the current rate and at a rate one or two percentage points higher. The sensitivity table shows the mathematical impact of a one-point move without assuming that move will occur. A comfortable loan should leave room for savings and unexpected costs after the EMI, rather than merely fitting a lender's maximum eligibility.
Home Loan Tax Treatment in India for AY 2026-27
Tax benefits depend on the chosen tax regime, property use, ownership, completion conditions and the current Income Tax rules. They should not be subtracted automatically from EMI. For Assessment Year 2026-27, the Income Tax Department states that an eligible old-regime taxpayer may claim up to ₹2,00,000 of interest for a qualifying self-occupied house under Section 24(b). Eligible housing-loan principal is included among Section 80C items within the combined ₹1,50,000 limit, not as an extra limit reserved for the loan.
Under the new regime, interest on a self-occupied property is not allowed as a deduction from house-property income. Treatment for let-out property, carried-forward losses, co-owners, pre-construction interest and sale-related reversals can be different. Use the official tax portal and a qualified tax professional for your facts, especially when ownership and borrowing shares differ.
Why Your Lender's EMI May Differ
- The lender accrues interest daily or uses a different day-count method.
- A broken-period charge applies between disbursement and the first regular EMI.
- The loan is disbursed in stages during construction.
- The floating benchmark resets and the lender changes EMI, tenure or both.
- Insurance, a fee or another charge is financed into principal.
- The lender rounds EMI, interest or principal at each step.
- A moratorium capitalizes interest before regular repayment begins.
- The lender applies prepayment on a different date or reduces EMI instead of tenure.
Use this tool to understand and compare scenarios, then reconcile it against the sanction letter, KFS and account statement. A small rounding difference is normal; a large difference usually signals a different principal, rate, timing convention, fee treatment or repayment structure.

Frequently Asked Questions
What is EMI on a home loan?
EMI is the equated monthly instalment used to repay principal and interest over the selected term. With a constant rate, the payment is broadly level while the interest and principal components change each month.
Does a longer tenure reduce home loan cost?
A longer tenure usually reduces EMI but increases total interest when principal and rate stay the same. Compare both monthly affordability and lifetime repayment.
How does prepayment save interest?
Prepayment lowers outstanding principal earlier. Future interest is then calculated on a smaller balance. Savings are generally larger when the same amount is paid earlier and EMI remains unchanged.
Does this calculator reduce EMI after prepayment?
No. It keeps the scheduled EMI constant and shortens the modeled tenure. Ask your lender whether a specific prepayment will reduce tenure, EMI or follow another instruction.
Are processing fees included in EMI?
Not unless they are financed into principal. This tool displays entered fees separately and adds them to total cash outflow. The lender's KFS should be used for regulated APR and charge disclosure.
Can a floating-rate home loan EMI change?
Yes. A benchmark reset can change EMI, tenure or both under the contract and applicable rules. The calculator holds the entered rate constant, while its sensitivity table helps test alternative rates.
Does the calculator include stamp duty and registration?
No. Those are property-acquisition costs, not standard EMI components. You may enter known loan-related upfront costs for a broader cash view, but keep categories clear when comparing offers.
Is the displayed income ratio a loan eligibility result?
No. It is a simple budget screen using the income and debt payments entered. Lenders use their own income definitions, FOIR rules, credit assessment, age and property criteria.
Sources and Methodology
The calculator uses the standard reducing-balance EMI equation and generates each amortization row from its opening balance. Current India-specific guidance was checked against the RBI floating-rate EMI reset circular, updated October 1, 2025, the RBI Key Facts Statement rules, and the Income Tax Department guidance for AY 2026-27. Lender pricing and borrower eligibility vary, so no advertised rate is treated as a market-wide assumption.
Financial disclaimer: This calculator provides educational estimates, not financial, tax, legal or lending advice. Actual EMI, APR, fees, tax treatment, prepayment rules, eligibility and payoff timing depend on your lender documents and circumstances. Verify the KFS, sanction letter, account statement and current official rules before acting.
