How We Calculate

The methods, data and checks behind the numbers on EMICalculate.in.

Last reviewed: 1 October 2026

The Short Version

Our EMI calculations use the reducing-balance method commonly used for loan EMIs. EMI amounts are rounded to the nearest rupee, and the final EMI may be adjusted so the loan closes at exactly zero.

Every calculator result is generated by code and tested before a page goes live. Numbers shown on our pages are generated from the same calculation logic used by the live calculator.

Rates and regulatory information are dated and reviewed on a schedule. We also explain the assumptions and items that our calculators do not include.

The EMI Formula

Our EMI calculations use the reducing-balance method.

EMI = P × r × (1 + r)n ÷ [(1 + r)n − 1]
P
Loan amount
r
Monthly interest rate: annual interest rate ÷ 12 ÷ 100
n
Total number of monthly EMIs

Each month, interest is calculated on the outstanding principal. The remaining part of the EMI goes towards reducing the principal.

As the outstanding principal falls, the interest portion generally falls and the principal portion increases.

How Each EMI Is Split

Example: ₹50 lakh at 7.5% for 20 years (240 EMIs).

MonthEMIInterestPrincipalBalance Left
1₹40,280₹31,250₹9,030₹49,90,970
2₹40,280₹31,194₹9,086₹49,81,884
3₹40,280₹31,137₹9,143₹49,72,740
……………
240₹40,092₹249₹39,843₹0

Figures are rounded to the nearest rupee, so manually adding rounded values can sometimes produce a small difference.

In the first month, ₹31,250 of the ₹40,280 EMI is interest. The principal portion gradually increases as the outstanding loan balance falls.

For this example, total interest over the full loan is ₹46,67,012.

Rounding and the Last EMI

We round the calculated EMI to the nearest rupee.

Because of this rounding, the final EMI may be adjusted slightly so that the outstanding loan balance reaches exactly zero.

In the example above, EMIs 1 to 239 are ₹40,280 and the final EMI is ₹40,092.

Totals shown on our pages are calculated from the resulting repayment schedule, so the total interest and total repayment match the schedule.

Other Figures We Calculate

Salary Needed

Where a calculator shows an estimated salary requirement, we use the selected EMI-to-income assumption. For example:

For a ₹40,280 EMI, these calculations give ₹80,560 and ₹1,00,700.

These are calculation scenarios, not universal lender requirements. Actual lender limits can vary based on income, existing obligations, credit profile and other factors.

Prepayment Savings

For our prepayment calculations, we rerun the repayment schedule after applying the additional payment according to the option selected.

Where the calculator keeps the EMI unchanged, the additional payment reduces the outstanding principal and can shorten the loan tenure.

Estimated interest saved is the difference between the original repayment schedule and the adjusted schedule. The exact result depends on the amount, timing and frequency of the prepayment.

Starting From Property Price

When a calculator starts with the property price, the loan amount is calculated from the property price and the down payment entered.

Where an LTV assumption is used, we show that assumption clearly rather than treating it as a universal lending limit.

If a processing fee is included, it is calculated using the fee percentage entered into the calculator.

Tenure and Rate Comparisons

For tenure and interest-rate comparisons, we run the same calculation again using the selected loan amount and the different tenure or rate shown in the comparison.

This allows you to see how changing one input affects the EMI, interest and total repayment.

EMI Per ₹1 Lakh

The EMI-per-₹1-lakh figure is calculated using a loan amount of ₹1,00,000 with the selected interest rate and tenure.

It can be used as a quick reference when comparing different loan amounts.

Rules and Regulatory Information

Some information used by our calculators or explanatory pages depends on current regulations.

We do not treat regulatory limits as universal rules where the applicable conditions can vary.

Loan-to-Value (LTV)

LTV requirements and limits can depend on the type of lender, loan amount, property and applicable regulatory rules.

Where our calculators use an LTV assumption, we show the assumption clearly. For an actual loan, check the lender's current terms and applicable RBI rules.

Prepayment Charges

Applicable RBI rules restrict certain prepayment charges for eligible floating-rate loans to individual borrowers.

The exact applicability can depend on the type of loan, borrower, lender and the rules applicable at the relevant time. Check your lender's current loan agreement and applicable rules before making a prepayment.

External Benchmark and Repo-Linked Rates

Some floating-rate loans are linked to an external benchmark such as the RBI repo rate.

For eligible retail and MSME floating-rate loans, banks are required to use external benchmark-based lending rates, with the applicable benchmark and reset terms forming part of the loan terms.

The exact benchmark and reset terms depend on the lender and loan agreement.

Tax

Tax treatment of home loans depends on the applicable income-tax rules, the type and use of the property, the loan and the tax regime selected.

Our EMI calculations do not include tax benefits or tax savings.

For current tax rules, refer to the Income Tax Department and your tax adviser. The Income Tax Department's current guidance shows that the availability of housing-loan deductions can differ between the old and new tax regimes and depending on the property and loan circumstances.

Where Our Bank Rates Come From

Where we show lender interest rates, we use rates published by lenders and may also cross-check them against reputable financial sources.

Each rate table shows the date the rates were checked.

Published starting rates may not be available to every borrower. Your actual rate can depend on factors such as your credit profile, income, loan amount, property and lender-specific criteria.

Our lender tables are not a complete list of every lender in India.

What Our Calculators Don't Include

Calculator results are estimates. Depending on the calculator, the following may not be included:

These differences can cause the figures from our calculators to differ from the final figures provided by a lender.

How We Check Every Number

We use multiple checks to reduce calculation and publishing errors.

Calculated by codeFigures are generated by code using the calculation methods described on this page. They are not manually typed into calculator results.
Calculator and page checksBefore a page goes live, we check that important numbers shown on the page match the live calculator output.
Independent calculation checksKey results, such as repayment and prepayment calculations, are checked against a separate calculation where appropriate.
Loan closure testsWe test different loan amounts, interest rates and tenures to make sure the repayment schedule closes correctly at zero.
Mobile and desktop checksPages are checked on both mobile and desktop screens before publication.

How Often We Review Our Information

Bank ratesReviewed monthly where lender-rate tables are maintained.
RBI and regulatory informationReviewed periodically and whenever relevant RBI rules or official guidance changes.
Tax informationReviewed periodically and when relevant government tax rules or official guidance changes.
