EMI stands for Equated Monthly Instalment — the fixed amount you pay the bank every month until your loan is fully repaid. This calculator works for any type of loan.
Banks use the formula: EMI = P × r × (1+r)^n / ((1+r)^n − 1) where P is the principal amount, r is the monthly interest rate, and n is the total number of monthly payments. This is called the reducing balance method, which means interest is charged only on the remaining principal — not on the original loan amount.
Here is what most people do not realise — in the early years of a long-term loan, most of your EMI goes toward paying interest, not reducing the loan. For a ₹50 lakh home loan at 8.5% for 20 years, your first month's EMI of about ₹43,391 has roughly ₹35,417 going to interest and only ₹7,974 toward reducing the actual principal. This ratio slowly reverses over the years as the outstanding balance drops.
Three things directly control your EMI — the loan amount, interest rate, and tenure. A longer tenure means lower monthly EMI but significantly more total interest. For instance, a ₹30 lakh loan at 8.5% costs ₹23,572/month for 20 years but ₹29,542 for 10 years. The shorter tenure costs ₹5,970 more per month but saves you ₹25.15 lakh in total interest over the life of the loan.
Always compare loan offers from multiple banks. Even a 0.25% difference in interest rate can save several lakhs over a 20-year home loan. Use our calculator above to test different scenarios — move the sliders and watch the numbers change in real time to find the combination that fits your budget.
This EMI calculator works for every type of amortising loan — home loans (typically 15-30 years at 8-10%), car loans (typically 3-7 years at 7-12%), personal loans (typically 1-5 years at 10-18%), and education loans (typically 5-15 years at 8-14%). Just adjust the three parameters to match your specific loan and you will get the accurate EMI figure.
Remember, the EMI shown by this calculator is the principal and interest component only. Your actual monthly outflow might be slightly higher if the bank charges processing fees upfront or if you have opted for loan insurance. Always ask the bank for a complete breakdown before signing.
