Calculate home loan EMI (Equated Monthly Installment), total interest, prepayment savings, and year-by-year amortization. Supports INR and 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. Indian home loan borrowers commonly take 15-25 year terms at rates between 8-9.5% — 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 lakhs in interest. Supports both INR and USD. Check the example with realistic values before reporting.
Home loan EMI calculations involve compound interest that is difficult to compute manually. This calculator gives you instant, accurate results with prepayment analysis — essential for understanding how lump-sum payments during the loan can save significant interest and reduce tenure. That makes it easier to 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.

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. This provides clearer practical guidance for reliable use.
When your floating rate changes, the lender adjusts either the EMI amount (keeping tenure same) or the tenure (keeping EMI same). Most Indian banks adjust the tenure by default — so a rate increase extends your loan duration rather than increasing the EMI.
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.
In India: principal repayment up to ₹1.5 lakh/year under Section 80C, interest up to ₹2 lakh/year under Section 24(b) for self-occupied property, and additional ₹1.5 lakh under Section 80EEA for first-time buyers (subject to conditions). Consult a CA for your specific case.
