Enter your loan amount, interest rate, and loan tenure to calculate your monthly EMI and total interest payable.
What is EMI?
Equated Monthly Installment (EMI) is a fixed payment amount made by a borrower to a lender at a specified date each calendar month. EMIs consist of both principal and interest components that are calculated using the following formula:
EMI = P × r × (1 + r)^n / ((1 + r)^n - 1)
Where P = Principal loan amount, r = Monthly interest rate, n = Number of monthly installments
Types of Loans
- Home Loan: Typically 15-30 years tenure with lower interest rates (7-10%)
- Car Loan: Usually 3-7 years tenure with moderate interest rates (8-12%)
- Personal Loan: Short tenure of 1-5 years with higher interest rates (10-18%)
- Education Loan: Flexible tenure with competitive rates and moratorium period
Factors Affecting EMI
- Principal Amount: Higher loan amount increases EMI
- Interest Rate: Higher rates result in higher EMIs
- Loan Tenure: Longer tenure reduces EMI but increases total interest
- Processing Fees: Additional charges that affect the total cost
Tips to Reduce EMI Burden
- Make a higher down payment to reduce the principal amount
- Choose a longer tenure to reduce monthly EMI (but total interest increases)
- Compare interest rates from different lenders
- Consider prepayment options to reduce interest burden
- Maintain a good credit score for better interest rates

- Key Insight: Early payments consist mostly of interest, while later payments pay more principal
Worked EMI Example
Consider a ₹30,00,000 home loan at 9% annual interest for 20 years. The monthly rate is 9% ÷ 12 = 0.75% (r = 0.0075) and the number of instalments is n = 240. Plugging into the formula gives an EMI of about ₹26,992. Over the full 20 years you repay roughly ₹64.8 lakh — meaning about ₹34.8 lakh is interest, more than the original loan amount itself. This is why the interest rate and tenure matter so much on long-term loans.
Reducing-Balance vs Flat Rate — Avoid the Trap
Always confirm whether a quoted rate is reducing-balance or flat. With reducing balance (used in this calculator and by most home and personal loans), interest is charged only on the outstanding principal, which shrinks every month. With a flat rate, interest is charged on the full original amount for the entire tenure. A 10% flat rate is roughly equivalent to an 18–19% reducing-balance rate — nearly double the real cost. Lenders sometimes advertise the lower-sounding flat rate, so compare loans only on their reducing-balance (or APR) basis.
How Prepayment Saves Interest
Because early EMIs are mostly interest, prepaying principal early in the loan has an outsized effect. On the ₹30 lakh example above, paying just one extra EMI per year can shorten the loan by several years and save several lakh rupees in interest. When you prepay, instruct the lender to reduce the tenure rather than the EMI — keeping the EMI the same while cutting months off the loan maximises your interest savings.
Frequently Asked Questions — EMI Calculator
EMI (Equated Monthly Instalment) is a fixed monthly payment made to a lender that covers both the principal repayment and the interest charged on the outstanding loan balance, spread equally over the loan tenure.
EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the total number of monthly instalments.
Prepayment reduces your outstanding principal directly. Depending on your lender's policy, this either shortens your remaining tenure (keeping EMI the same) or reduces future EMI amounts. Both options save you significant interest.
Home loans typically have the lowest EMI because they have the longest tenures (up to 30 years) and lowest interest rates (8–10%). Personal loans have the highest EMI due to short tenure (1–5 years) and higher rates (12–24%).
A missed EMI attracts a late payment penalty (typically 1–2% of the overdue amount), negatively impacts your CIBIL credit score, and may lead to the account being classified as NPA if missed repeatedly.
Yes — you can either do a balance transfer to a lender offering a lower interest rate, or request a tenure extension from your existing lender. Both reduce the monthly outgo, though tenure extension increases total interest paid.
