What is EMI?
EMI stands for Equated Monthly Instalment. It is a fixed payment that a borrower makes to a lender on a specific date every month until the loan is fully repaid. Each EMI payment consists of two components: the principal repayment and the interest charge on the outstanding loan balance.
In the early months of a loan, a larger portion of the EMI goes toward interest. As the loan progresses, more of each payment is applied to the principal. This is how the reducing balance method works, and it is the standard calculation method used by banks and NBFCs in India.
- EMI remains constant throughout the loan tenure, making budgeting easier for borrowers
- Each payment includes both principal repayment and interest, with the ratio shifting over time
- EMI is used for home loans, personal loans, vehicle loans, business loans, and MUDRA loan for restaurants
- The reducing balance method is standard in India, resulting in lower total interest compared to flat rate loans
How is EMI Calculated?
EMI is calculated using a standard mathematical formula based on three inputs: the loan principal, the interest rate, and the loan tenure. This formula uses the reducing balance method, where interest is charged only on the outstanding principal.
EMI = P × r × (1+r)n / ((1+r)n - 1)
P (Principal): The total loan amount borrowed from the lender
r (Monthly Interest Rate): Annual interest rate divided by 12 and then by 100. For example, 8.5% annual = 0.085/12 = 0.007083
n (Number of Months): Total loan tenure in months. For example, 5 years = 60 months
Once you know the EMI, you can also calculate the total interest payable as (EMI x n) minus P, and the total payment as EMI x n. This helps you understand the true cost of borrowing before you commit to a loan. Use our GST calculator if you need to factor in GST on processing fees.
EMI Calculation with Example
Let us work through a practical example. Suppose you are taking a loan of ₹10,00,000 at an annual interest rate of 8.5% for a tenure of 5 years (60 months).
Loan Amount (P): ₹10,00,000
Annual Interest Rate: 8.5%
Monthly Interest Rate (r): 8.5 / 12 / 100 = 0.007083
Tenure (n): 60 months
EMI Calculation: 10,00,000 x 0.007083 x (1.007083)^60 / ((1.007083)^60 - 1)
Monthly EMI: ₹20,517 (approximately)
Total Payment: ₹20,517 x 60 = ₹12,31,020
Total Interest Payable: ₹12,31,020 - ₹10,00,000 = ₹2,31,020
In this example, you would pay approximately ₹2.31 lakhs as interest over 5 years. If you extended the tenure to 7 years, the EMI would drop to around ₹15,870, but the total interest would increase to approximately ₹3.33 lakhs. This trade-off between lower EMI and higher total interest is important to consider when choosing your loan tenure.
Why is EMI Important?
Understanding your EMI before taking a loan is critical for sound financial planning, whether you are an individual or a business owner. Here is why EMI calculation matters:
- Budget planning: Knowing your exact monthly obligation helps you plan your cash flow. Financial experts recommend keeping total EMIs below 40-50% of your monthly income
- Loan comparison: Calculating EMI for different interest rates and tenures helps you compare loan offers from multiple banks and NBFCs before making a decision
- Total cost visibility: The EMI formula reveals the total interest you will pay over the loan tenure, helping you understand the true cost of borrowing
- Business decisions: Restaurant owners and entrepreneurs can use EMI calculations to assess whether a business loan or equipment financing fits within their operating margins. Use our profit margin calculator to check affordability
- Prepayment planning: Understanding how much interest you save by prepaying helps you decide when partial or full prepayment makes financial sense

Types of Loans in India
Understanding the different loan types helps you choose the right product for your needs. Here are the most common loan categories in India:
- MUDRA Loans: Government-backed loans for micro and small businesses under the MUDRA scheme. Available in three tiers: Shishu (up to ₹50,000), Kishore (₹50,000 to ₹5 lakh), and Tarun (₹5 lakh to ₹10 lakh). Ideal for restaurant startups and food truck operators
- MSME Loans: Business loans for Micro, Small, and Medium Enterprises. Interest rates range from 8% to 16%. Available through banks, NBFCs, and government schemes like CGTMSE
- Home Loans: Loans for purchasing residential property. Typically have the lowest interest rates (8-10%) and longest tenures (up to 30 years)
- Personal Loans: Unsecured loans for any purpose. Interest rates are higher (10-18%) since no collateral is required. Tenure is usually 1 to 5 years
- Vehicle Loans: Loans for purchasing cars, commercial vehicles, or delivery vehicles. Interest rates range from 7% to 12% with tenures up to 7 years
- Business Equipment Loans: Loans for purchasing kitchen equipment, POS systems, or restaurant machinery. Interest rates vary from 10% to 15% depending on the lender and business profile
Factors That Affect Your EMI
Several factors determine the EMI amount you will pay each month. Understanding these helps you negotiate better loan terms and make informed decisions:
- Interest rate: Even a small change in interest rate has a significant impact on EMI. For a ₹10 lakh loan over 5 years, reducing the rate from 10% to 8.5% saves approximately ₹400/month and over ₹24,000 in total interest
- Loan tenure: Longer tenure reduces the monthly EMI but increases the total interest paid. Shorter tenure means higher EMI but lower overall cost. Use the break-even calculator to see when your business can absorb higher EMIs
- Loan amount: The principal directly affects EMI. Borrowing more means a higher EMI. Always borrow only what you need and can comfortably repay
- Processing fees: While not part of the EMI formula, processing fees (typically 1-2% of loan amount) add to the effective cost. Some lenders add this to the loan amount, increasing your EMI
- Floating vs fixed rate: Floating rate loans may see EMI changes when the RBI adjusts repo rates. Fixed rate loans keep the EMI constant but usually start at a slightly higher rate
EMI vs Flat Rate vs Reducing Balance
When comparing loan offers, it is important to understand the difference between flat rate and reducing balance interest calculation methods. The same stated interest rate will result in very different total costs depending on which method is used.
Flat Rate Method: Interest is calculated on the original loan amount for the entire tenure. For a ₹10 lakh loan at 8% flat rate for 5 years: Interest = 10,00,000 x 8% x 5 = ₹4,00,000. Total repayment = ₹14,00,000. Monthly payment = ₹23,333
Reducing Balance Method: Interest is calculated on the outstanding principal, which decreases with each EMI payment. For the same loan: EMI = ₹20,276. Total repayment = ₹12,16,560. Total interest = ₹2,16,560
Difference: The flat rate method costs ₹1,83,440 more in interest for the same loan. Always ask your lender which method they use
Most banks and NBFCs in India use the reducing balance method, which is more favorable for borrowers. However, some microfinance institutions and older NBFCs still use the flat rate method, especially for smaller loans. Always confirm the calculation method before signing your loan agreement.
