How It Works
The EMI Formula
The standard reducing balance EMI formula used by all major banks globally
Formula
EMI = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1]
Variables
Principal (Loan Amount)
The total amount of money you are borrowing from the lender. For home loans this is the property price minus your down payment. For car loans it is the vehicle cost minus your down payment or trade-in value.
Monthly Interest Rate
The annual interest rate divided by 12. If your bank offers 10% per annum, the monthly rate r = 10 ÷ (12 × 100) = 0.00833. This is the rate applied to your remaining balance each month.
Number of Monthly Instalments
The total number of monthly payments — your loan term in months. A 5-year loan = 60 months; a 20-year home loan = 240 months. The longer n is, the lower your monthly EMI but the more total interest you pay.
Equated Monthly Instalment
The fixed amount you pay every month for the entire loan term. Each EMI contains both a principal component and an interest component. In early months, most of the EMI is interest; in later months, most is principal repayment.
Note: This is the reducing balance method (also called diminishing balance), used by all RBI-regulated banks in India, SBP-regulated banks in Pakistan, and most formal lending institutions globally. The flat rate method — sometimes used by unregulated lenders — calculates interest on the original principal throughout the term, making the effective interest rate significantly higher than advertised.
Step-by-Step EMI Example
Home loan of ₹10,00,000 (10 lakhs) at 10% per annum for 5 years
Identify the principal
P = ₹10,00,000
Convert annual rate to monthly rate
r = 10% ÷ 12 ÷ 100 = 0.008333
Calculate the loan term in months
n = 5 years × 12 = 60 months
Calculate (1 + r)ⁿ
(1 + 0.008333)⁶⁰ = (1.008333)⁶⁰ = 1.6453
Apply the EMI formula
EMI = 10,00,000 × 0.008333 × 1.6453 ÷ (1.6453 − 1)
Complete the calculation
EMI = 8333 × 1.6453 ÷ 0.6453 = 13,710.6 ÷ 0.6453 = ₹21,247 per month
Calculate total amount paid
Total Paid = ₹21,247 × 60 = ₹12,74,820
Calculate total interest paid
Total Interest = ₹12,74,820 − ₹10,00,000 = ₹2,74,820 (27.48% extra over principal)

Understanding Your EMI Results
What the numbers mean for your financial decision
Financial advisors and banks globally recommend keeping your total monthly EMI obligations below 30% of your gross monthly income. At this level, you have sufficient income for living expenses, savings, and emergencies. Most banks will approve loans that keep you in this range.
Best for: Target zone for sustainable borrowing
You are carrying a significant debt load. While banks may still approve this, any income disruption — job loss, medical emergency, pay cut — will cause immediate financial stress. Consider increasing your down payment or extending the loan term to reduce the monthly EMI.
Best for: Acceptable if income is very stable and you have an emergency fund
Most banks will reject a loan application at this ratio. Even those that approve it expose you to severe financial risk. A high EMI-to-income ratio is one of the leading causes of loan default and debt traps. Strongly reconsider the loan amount or term.
Best for: Reconsider the loan: reduce principal, extend term, or delay until income increases
This is the true cost of borrowing. A 10% annual rate over 5 years adds approximately 27% to your total payment. Over 20 years, the same rate can add 115%+ — meaning you pay more than double the original loan amount. Always check the total interest, not just the monthly EMI.
Best for: The lower this percentage, the better the loan deal
What Is EMI — and How Does Amortisation Work?
An Equated Monthly Instalment (EMI) is the fixed amount a borrower pays to a lender on a specified date each calendar month. EMIs are structured so that each payment covers both the interest accrued on the outstanding balance and a portion of the principal, in a fixed total amount throughout the loan term. The word 'equated' is key: the monthly payment amount does not change. What changes is the split between principal and interest within each payment. This structure is called amortisation. In the early months of a loan, most of each EMI payment covers interest — because interest is calculated on the full outstanding principal. As you make payments and the principal reduces, the interest portion decreases and the principal portion increases. By the final months, almost the entire EMI payment is principal repayment. This is why making extra payments early in a loan term has a dramatically larger impact than making the same extra payments late. An extra payment in month 1 reduces the principal you pay interest on for all remaining months. An extra payment in month 55 of a 60-month loan saves you only 5 months of interest on that amount. Understanding the difference between flat rate and reducing balance interest is critical before signing any loan agreement. A flat rate loan charges interest on the original principal throughout the entire term — even as you repay it. A reducing balance loan (the standard bank method and what our calculator uses) charges interest only on the remaining outstanding balance. A 10% flat rate is roughly equivalent to a 17–18% reducing balance rate — making it far more expensive than it appears.
Key Features
💡 Pro Tips
- →Paying one extra EMI per year reduces a 20-year home loan to approximately 17 years — saving roughly 3 years of interest payments. The math is striking.
- →When comparing loan offers, never compare monthly EMI alone. Always compare the total interest paid over the full term. A lower EMI with a longer term often costs significantly more in total.
- →The first 6 months of any loan are the most expensive in interest terms. If you receive a bonus or lump sum early in the loan period, prepaying it has a disproportionately large impact.
- →Most Indian and Pakistani banks allow loan prepayment after a lock-in period (typically 6–12 months for home loans). Check your loan agreement for prepayment penalty clauses before making extra payments.
- →The EMI-to-income ratio your bank uses is calculated on gross income. Your actual affordability depends on net take-home income after taxes and deductions — always run both calculations.
Common Mistakes
Comparing loans by monthly EMI only
A 25-year loan will always have a lower monthly EMI than a 15-year loan at the same rate — but the 25-year loan can cost 60–80% more in total interest. Always compare total interest paid, not just the monthly payment.
Confusing flat rate with reducing balance interest
A lender advertising '10% flat rate' is not offering the same deal as '10% reducing balance.' The flat rate is calculated on the original principal throughout — the effective annual rate is approximately 17–18%. This distinction is critical and frequently exploited by informal lenders.
Ignoring processing fees and insurance in the cost of borrowing
Banks charge processing fees (0.5–2% of loan amount), insurance premiums, and legal fees that are not captured in the EMI. The true cost of borrowing — the Annual Percentage Rate (APR) — includes all fees and is always higher than the stated interest rate.
Assuming you cannot renegotiate the interest rate
After 2–3 years of consistent EMI payments, borrowers with good credit history can often negotiate a rate reduction or refinance with another lender. Even a 0.5% rate reduction on a ₹50 lakh home loan saves approximately ₹4–5 lakhs in total interest.
Not accounting for EMI when calculating total loan capacity
Many borrowers calculate the maximum loan they qualify for based on bank approval — not based on comfortable affordability. Bank approval limits can be up to 50–55% of income; the financially healthy limit is 30–35%. Borrowing to the bank maximum leaves no buffer for emergencies.

Frequently Asked Questions
What is EMI and how is it calculated?
EMI stands for Equated Monthly Instalment — the fixed monthly payment you make to repay a loan over a set period. It is calculated using the formula: EMI = P × r × (1+r)ⁿ ÷ [(1+r)ⁿ − 1], where P is the principal loan amount, r is the monthly interest rate (annual rate divided by 12 and by 100), and n is the number of monthly payments. Each EMI contains both an interest component and a principal repayment component. Early payments are mostly interest; later payments are mostly principal.
What is the EMI for a 10 lakh loan?
For a ₹10,00,000 (10 lakh) loan at 10% per annum for 5 years, the monthly EMI is approximately ₹21,247. For a 10-year term at the same rate, the EMI drops to approximately ₹13,215 but total interest paid increases from ₹2.74 lakhs to ₹5.86 lakhs. Use our calculator to find the exact EMI for your specific loan amount, rate, and term.
How does making extra payments affect my loan?
Extra payments reduce your outstanding principal balance, which reduces the interest charged on every subsequent month (since interest is calculated on the remaining balance). Even a small additional payment each month can significantly shorten the loan term and save lakhs in interest. For example, on a 20-year home loan of ₹50 lakhs at 9%, paying just ₹5,000 extra per month can cut the loan to approximately 15 years and save over ₹15 lakhs in interest.
What is the difference between flat rate and reducing balance interest?
Flat rate charges interest on the original loan amount for the entire term — so even as you repay principal, you keep paying interest on the full original amount. Reducing balance (used by all banks) charges interest only on the outstanding remaining balance, which decreases each month. A flat rate of 10% is equivalent to approximately 17–18% on a reducing balance basis. Always confirm which method your lender uses — formal banks use reducing balance; some informal lenders use flat rate.
Can I use this as a mortgage calculator?
Yes. A mortgage is simply a long-term secured loan. Enter your home loan amount, annual interest rate, and term in months (a 20-year mortgage = 240 months). The calculator gives your monthly payment and full repayment schedule. Note that mortgage repayments may also include property taxes and insurance (PITI in the US context) which are separate from the pure EMI this calculator computes.
What is a good EMI-to-income ratio?
Financial advisors globally recommend keeping total EMI obligations (all loans combined) below 30% of gross monthly income. Banks in India typically approve home loans where the EMI does not exceed 40–55% of gross income. The Reserve Bank of India and State Bank of Pakistan both have guidelines for responsible lending that reference debt service ratios. For long-term financial health, target below 30%.
