Calculate home loan EMI (Equated Monthly Installment), total interest, prepayment savings, and year-by-year amortization. Use it for general planning in INR or USD.
EMI (Equated Monthly Installment) is the fixed monthly payment you make toward repaying a home loan. Each EMI consists of a principal component and an interest component — in early years, most of the EMI goes toward interest, while in later years, more goes to principal repayment.
Understanding your EMI is essential for budgeting and comparing loan offers. A lower EMI means lower monthly burden, but often means paying more total interest over a longer term. Borrowers commonly stretch home loans over long tenures at rates in the high single digits, making the interest component substantial.
This calculator computes EMI for any loan amount, rate, and tenure. It shows the total interest paid compared to principal, rate sensitivity analysis for floating-rate scenarios, and a year-by-year amortization schedule. The prepayment feature shows how a lump-sum payment can reduce your tenure and save interest. Use it as a planning calculator, then verify lender-specific pricing, fees, and tax treatment for the country and year that apply to you.
Home loan EMI calculations involve compound interest that is difficult to compute manually. This calculator gives you a planning estimate with prepayment analysis so you can compare affordability today with total borrowing cost over time.
EMI = P × r × (1+r)^n / [(1+r)^n − 1], where P = principal, r = monthly interest rate, n = total number of monthly installments.
Result: EMI: ₹43,391 — Total interest: ₹54,13,840 — Interest is 108% of principal
A ₹50 lakh home loan at 8.5% for 20 years results in an EMI of ₹43,391. Total interest over the tenure is ₹54.1 lakhs — actually exceeding the principal amount. A ₹5 lakh prepayment in year 5 would save approximately ₹8.5 lakhs in interest.
An EMI is designed to stay constant even though the split between interest and principal changes every month. Early installments are interest-heavy because the outstanding balance is still large. Later installments pay down principal faster as the balance falls.
Stretching a loan from 15 years to 25 years lowers the monthly EMI, but it usually increases the total interest dramatically. That tradeoff matters more than the monthly number alone, especially on large mortgages where even a small rate difference compounds for decades.
Prepayments work best early in the loan because they cut principal before the heaviest interest years have passed. Even one annual lump-sum payment or a modest monthly top-up can reduce both total interest and overall tenure more than most borrowers expect.

This calculator uses the standard amortizing-loan EMI formula with monthly compounding. It computes a fixed monthly principal-and-interest payment from the entered principal, annual rate, and term, then builds a yearly amortization schedule by stepping through each month and allocating the payment between interest and principal. If a prepayment amount is entered, the current implementation applies it as a one-time principal reduction in the selected year.
The rate-comparison table is a sensitivity check, not a lender quote sheet. It shifts the entered annual rate by plus or minus 1.5 percentage points to show how payment and total interest would change, so the result should be used for planning rather than as a commitment or product-specific pricing estimate.
EMI is calculated using the standard amortization formula: 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), and n is the total number of monthly installments.
When a floating rate changes, the lender may adjust either the payment amount, the remaining tenure, or both. The exact method depends on the product terms and local lending practices, so confirm how your own loan documents handle resets.
Financial advisors recommend keeping total EMI obligations (all loans) below 40-50% of your net monthly income. For comfort, home loan EMI alone should ideally be under 30-35% of your take-home salary.
Prepayment reduces the principal balance, which reduces future interest charges. A prepayment early in the loan tenure (first 5-7 years) has the maximum impact because that is when interest charges are highest. Most banks allow prepayment without penalty on floating rate loans.
Reducing tenure saves more interest overall (recommended if EMI is affordable). Reducing EMI provides immediate cash flow relief. If you can maintain the current EMI, always choose to reduce tenure — the savings compound significantly.
Tax treatment depends on the country, filing status, property use, and year in question. Treat the page as payment-planning guidance and confirm the current deduction or exemption rules that apply to your loan.
