What is an EMI?
An Equated Monthly Instalment (EMI) is the fixed amount you pay your lender every month until a loan is fully repaid. Each EMI has two parts: interest on the outstanding balance and repayment of principal. In the early years most of the EMI goes towards interest; as the balance falls, a larger share goes towards principal. This is called the reducing-balance method and it is what every Indian bank, NBFC and housing finance company uses for home, car, personal and education loans.
How to use this EMI calculator
Enter the loan amount, the annual interest rate quoted by the lender and the tenure in years or months. The EMI, total interest and total payment update instantly. Open the amortization schedule to see how much principal and interest you pay in each year and what balance remains — useful when deciding whether to prepay.
EMI formula
EMI = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1]
- P = loan amount (principal)
- r = monthly interest rate = annual rate ÷ 12 ÷ 100
- n = number of monthly instalments
Example: A ₹25 lakh home loan at 8.5% for 20 years gives r = 0.007083 and n = 240. EMI ≈ ₹21,696, total interest ≈ ₹27.07 lakh and total repayment ≈ ₹52.07 lakh.
Tips to reduce your EMI or total interest
- Compare tenure options. A shorter tenure raises the EMI but can cut total interest by lakhs. Use the schedule to compare 15 vs 20 years.
- Prepay early. Because early EMIs are interest-heavy, even one extra EMI per year in the first five years shortens the loan substantially. Floating-rate home loans in India have no prepayment penalty for individuals.
- Negotiate the rate. A 0.25% difference on a ₹50 lakh loan over 20 years is roughly ₹1.9 lakh in interest.
- Check the processing fee and insurance add-ons, which are not part of the EMI but affect the true cost.
Home loan, car loan and personal loan EMIs
The same formula applies to all of them; only typical rates and tenures differ. Home loans run 7.5–10% for up to 30 years, car loans 8.5–12% for up to 7 years, and personal loans 10.5–24% for up to 5 years. Enter the rate from your sanction letter for an exact figure.
Frequently asked questions
How is EMI calculated?
EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the number of monthly instalments.
Does a longer tenure reduce my EMI?
Yes, a longer tenure lowers the monthly EMI but increases the total interest you pay over the life of the loan. Use the amortization table to compare options.
Is this EMI calculator accurate for Indian banks?
It uses the standard reducing-balance formula that SBI, HDFC, ICICI and other Indian lenders use. Actual EMI may differ slightly due to processing fees, rounding or the disbursement date.
