How this calculator works
An EMI is the fixed monthly instalment that covers both interest and principal on a reducing-balance loan. Most Indian home, car and personal loans use this method.
Enter principal, annual rate (% p.a.) and tenure in years. You get monthly EMI, total interest, total payment and a year-by-year schedule. Figures are indicative estimates, not a lender offer.
Use this hub to compare tenures and rates. Switch to the home loan EMI calculator, personal loan EMI calculator or car loan EMI calculator when you already know the product. Check comfort with the loan affordability calculator after you know the EMI.
- Enter the loan amount (principal).
- Enter the annual interest rate (% p.a.).
- Enter tenure in years.
- Read monthly EMI, total interest and total payment, then open the schedule if you want the principal vs interest split by year.
Formula
EMI = P × r × (1+r)^n / ((1+r)^n − 1)
Use the formula above when r > 0. If r = 0, EMI = P / n.
This tool uses the standard reducing-balance EMI identity. Interest is charged on the outstanding principal each month, not on the original amount for the full tenure.
P= principal (loan amount in ₹)r= monthly rate = annual % p.a. ÷ 12 ÷ 100n= number of months = years × 12
Example conversion: 8% p.a. → r = 8 / 12 / 100 ≈ 0.006667. For 20 years, n = 240.
Assumptions: Fixed rate for the full tenure sketch; equal monthly instalments; no processing fee, insurance, GST on charges, moratorium or floating reset unless you fold those into the inputs yourself. Step-by-step method: how EMI is calculated.

More about this calculator
Understanding EMI
EMI means equated monthly instalment: one payment each month that is the same size for the full tenure under a fixed-rate sketch. Part of every EMI pays interest on what you still owe. The rest reduces principal.
EMI does not automatically include processing fees, stamp duty, insurance premiums or GST on lender charges. Those sit outside the formula unless you add them to principal or budget them separately. For product-framed defaults, use the home, car, personal, gold, education or business loan EMI tools.
Real-world examples
Chip presets include page defaults (₹10L · 7.5% · 30y) and the teaching scenario below (₹10L · 8% · 20y). Load a chip to match the calculator to the numbers in each example.
Example 1: ₹10,00,000 at 8% p.a. for 20 years
Given: principal ₹10,00,000 · rate 8% p.a. · tenure 20 years (240 months).
Convert: monthly rate r ≈ 0.006667; n = 240.
Result: monthly EMI ≈ ₹8,364.40 · total interest ≈ ₹10,07,456.17 · total payment ≈ ₹20,07,456.17.
Takeaway: Over 20 years you repay roughly double the principal in this sketch. Interest is about as large as the loan itself.
Example 2: same loan, 15 years vs 25 years
Only tenure changes. Principal ₹10,00,000 and rate 8% p.a. stay fixed.
| Tenure | Monthly EMI | Total interest | Total payment |
|---|---|---|---|
| 15 years (180 months) | ₹9,556.52 | ₹7,20,173.75 | ₹17,20,173.75 |
| 20 years (240 months) | ₹8,364.40 | ₹10,07,456.17 | ₹20,07,456.17 |
| 25 years (300 months) | ₹7,718.16 | ₹13,15,448.66 | ₹23,15,448.66 |
Why EMI falls when tenure rises: the same principal is spread over more months, so each instalment is smaller. Interest still accrues every month on the outstanding balance, so a longer clock raises total interest.
Why shorter tenure costs more each month but less overall: at 15 years EMI is about ₹1,192 higher than at 20 years, yet total interest is roughly ₹2.87 lakh lower. At 25 years EMI eases by about ₹646 vs 20 years, while total interest rises by about ₹3.08 lakh. Pick the tenure you can pay monthly without treating “lowest EMI” as the goal.

Example 3: page defaults chip
Given: load 10L · 30y on the calculator: ₹10,00,000 · 7.5% p.a. · 30 years (360 months).
Result: monthly EMI ≈ ₹6,992.15 · total interest ≈ ₹15,17,172.23 · total payment ≈ ₹25,17,172.23.
Takeaway: Long tenure softens the monthly hit and stretches interest cost. See the insight block below for what those defaults mean as shares and ratios.
What the default result means
Using the page defaults on first load (₹10,00,000 · 7.5% p.a. · 30 years / 360 months), this calculator shows monthly EMI ≈ ₹6,992.15, total interest ≈ ₹15,17,172.23 and total payment ≈ ₹25,17,172.23.
Interest is about 60.3% of total repayment, or roughly ₹151.72 of interest for every ₹100 borrowed. Total payment is about 2.52× principal. On this default sketch, interest exceeds the principal itself.
Decision angle: a soft long-tenure EMI still sends about six-tenths of every repaid rupee to interest. If cash flow allows, shortening tenure (try a 20-year sketch at the same 7.5% rate) cuts interest hard even though EMI rises. Change the sliders for your quote; these figures are the default page-load example only.
Principal vs interest
On a reducing-balance loan, outstanding principal is highest on day one. Early EMIs are therefore interest-heavy: most of the instalment services interest and only a smaller slice cuts principal.
As the balance falls, the interest portion shrinks and more of each EMI goes to principal. That is why the year schedule looks “back-loaded” on principal even though the EMI rupee amount stays flat. Open the schedule on this page after you calculate. The split is easier to trust when you see it year by year.
How tenure affects EMI
Tenure is the strongest lever most borrowers control after principal. Holding rate and amount fixed:
- Shorter tenure → higher EMI, lower total interest, faster equity build-up.
- Longer tenure → lower EMI, higher total interest, slower principal pay-down.
Stress-test at least two tenures before you treat any EMI as “comfortable.” A payment that fits this month can still be expensive over 25–30 years.
How interest rate affects EMI
Rate moves EMI less dramatically than large tenure jumps for the same loan, but it compounds over hundreds of months. Same ₹10L / 20 years sketch:
| Rate (% p.a.) | Monthly EMI | Total interest |
|---|---|---|
| 7% | ₹7,752.99 | ₹8,60,717.45 |
| 8% | ₹8,364.40 | ₹10,07,456.17 |
| 9% | ₹8,997.26 | ₹11,59,342.29 |
One percentage point is not a rounding error on a long loan. For floating-rate offers, add about 0.5–1% on this calculator and re-check EMI and total interest. Trade-offs: fixed vs floating interest.
Rate stress on the defaults (7.5% vs 8.5%)
Principal ₹10,00,000 · tenure 30 years. Only the rate moves from the page default.
| Rate (% p.a.) | Monthly EMI | Total interest | Total payment |
|---|---|---|---|
| 7.5% | ₹6,992.15 | ₹15,17,172.23 | ₹25,17,172.23 |
| 8.5% | ₹7,689.13 | ₹17,68,088.54 | ₹27,68,088.54 |
Takeaway: +1 percentage point raises EMI by about ₹697 and adds roughly ₹2.51 lakh interest over 30 years. Run this stress before you treat a floating-linked quote as fixed for budgeting.
When a lower EMI is not better
A lower EMI usually means you stretched tenure, not that the loan got cheaper. Paying about ₹7,700 for 25 years can cost far more interest than paying about ₹9,500 for 15 years on the same principal and rate.
Lower EMI is also a weak signal when the quote uses a flat rate, hides fee-loaded principal or ignores insurance add-ons. Compare total payment and the schedule, not only the monthly number. If cash flow is the constraint, pair this tool with the loan affordability calculator rather than maxing eligibility on the loan eligibility calculator.
Common EMI mistakes
- Matching a flat-rate brochure EMI to this reducing-balance calculator without converting methods.
- Ignoring processing fees, insurance or GST on charges when judging “cheapest.”
- Entering months in a years field (or the reverse on another site).
- Choosing tenure only to minimise EMI, then underestimating total interest.
- Treating eligibility capacity as the same as a budget you can sustain. Check take-home with the salary calculator if needed.
- Skipping a +1% rate stress test on floating loans.
Tips before taking a loan
Try a slightly shorter tenure and note the interest saved against the EMI rise. Keep EMI within a share of take-home pay you can hold after rent, school fees and existing EMIs, then confirm capacity with affordability, not only eligibility.
Ask whether the quoted rate is flat or reducing. Confirm fixed vs floating and whether fees are deducted from disbursal. Practical levers to cut the instalment: how to reduce EMI. Until dedicated prepayment or balance-transfer tools ship on Kalkulator.in, model a lower principal or shorter remaining tenure here as a rough proxy.
Frequently misunderstood concepts
Flat rate vs reducing balance
This calculator uses reducing balance: interest each month is on the outstanding principal. A flat rate charges interest on the original principal for the full tenure, so the same headline % can hide a higher effective cost. If a dealer EMI does not match this tool at the same rate and tenure, ask which method they used. Side-by-side walkthrough: EMI vs reducing balance.
Eligibility vs affordability
Eligibility asks what a lender’s formula might allow. Affordability asks what your monthly budget can carry without stress. They diverge often. Run both the eligibility and affordability calculators after you know the EMI.
EMI vs simple interest
EMI amortises principal and interest together under the reducing-balance identity. A simple interest calculator answers a different question (interest = P × R × T without the equated instalment schedule). Do not mix the two when comparing loan offers.
Zero interest edge case
If annual rate is 0%, there is no interest component: EMI is simply principal ÷ number of months. Marketing “zero interest” schemes may still add processing fees or inflate the product price. Check the cash price vs financed price.
Important notes
Methodology: Reducing-balance EMI with monthly rate = annual % p.a. ÷ 12 ÷ 100 and tenure in months = years × 12. Schedule rows expand to monthly principal, interest and balance. Totals use round(emiRaw × n, 2); interest = total payment − principal; EMI displayed as round(emiRaw, 2).
Included: Principal, rate and tenure you enter.
Excluded by default: Processing fees, insurance, GST on fees, penalties, floating-rate resets, moratorium interest and foreclosure charges unless you fold them into the inputs yourself.
Results are indicative estimates for education and comparison, not a loan offer, approval or financial advice. Confirm figures with your lender’s sanction letter and amortisation schedule.

FAQs
EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is principal, r is monthly rate (annual % p.a. ÷ 12 ÷ 100) and n is months (years × 12). If rate is 0%, EMI = P ÷ n. This page uses that reducing-balance identity.
Convert the annual rate to a monthly decimal (divide by 12 and by 100), convert years to months, then apply the formula above. For a walkthrough with symbols and unit conversion, see how EMI is calculated. Use this calculator to check your arithmetic.
EMI is the fixed monthly instalment. Interest is the borrowing cost portion inside those instalments over the full tenure. Total payment = principal + total interest. Early EMIs are usually interest-heavy on reducing-balance loans.
Lenders may add processing fees, insurance, different day-count conventions, floating resets or (rarely) a flat-rate method. This tool shows indicative EMI from the principal, rate and tenure you enter, not a sanction letter.
Flat interest is charged on the original principal for the full tenure. Reducing-balance interest is charged only on the outstanding principal, so the interest share of each EMI falls over time. This calculator uses reducing balance. See EMI vs reducing balance.
This tool uses years. Internally, n = years × 12. The schedule expands each year into monthly principal, interest and balance.
Not always. Compare processing fees, prepayment charges, insurance add-ons and whether the rate is fixed or floating. Judge total payment and the schedule, not only the headline rate.
No. Default results use only principal, annual rate and tenure. Add fees into the principal or budget them in cash when you compare offers.
Outstanding principal is highest at the start, so early EMIs are interest-heavy. Later EMIs shift toward principal. Open the year schedule on this page to see the split.
Often yes, within lender rules: part-prepayment may cut EMI or tenure; a rate reset on a floating loan can raise or lower EMI; some lenders allow tenure restructuring. Confirm options in your agreement. This calculator only sketches what-if inputs.
Paying extra principal early reduces the balance that future interest is charged on, so total interest falls. Lenders typically let you choose a lower EMI or a shorter tenure after prepayment. Model a smaller principal or shorter tenure here as a rough proxy until a dedicated prepayment tool is available.
EMI equals principal divided by the number of months. There is no interest component in the formula. Still check fees and whether the product’s cash price was inflated versus a zero-interest finance offer.
Lower the principal (larger down payment), negotiate a better rate or extend tenure. Each has a cost. Part-prepayment can cut EMI or tenure depending on lender rules. See how to reduce EMI.
Enter the rate you expect to pay. For floating loans, stress-test +0.5% to +1% on this calculator. For the trade-offs, read fixed vs floating interest.
On long tenures, interest accrues every month on the outstanding balance. Using the page defaults (₹10 lakh · 7.5% · 30 years), total interest is about ₹15.17 lakh, more than the ₹10 lakh principal. Shorter tenure cuts that cost. Open the schedule to see how early years stay interest-heavy.
