Mortgage Calculator

What is Mortgage Calculator?

The Mortgage/Home Loan Calculator helps you estimate your monthly EMI, total interest payable over the loan tenure, and provides a full amortization schedule. It also helps compare offers from different banks.

How to Calculate Mortgage/Home Loan EMI

1. Enter your home loan amount (principal)
2. Enter the annual interest rate (check your bank's current home loan rate)
3. Enter the loan tenure in years (up to 30 years)
4. Click Calculate to see monthly EMI, total interest, and amortization table

How Mortgage Calculator is Calculated

Home loan EMI uses the standard reducing balance formula: EMI = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1). The amortization schedule shows how each monthly payment splits between principal repayment and interest.

Worked Example

Home loan ₹75,00,000 at 8.75% for 25 years (300 months): Monthly EMI = ₹62,282. Total interest = ₹1,11,84,600. Total amount paid = ₹1,86,84,600. Interest exceeds the principal by ₹36,84,600.

Common Use Cases

• Home buying budget planning
• Comparing bank home loan offers
• Prepayment benefit analysis
• Tax benefit calculation under Section 24b & 80C

Common Mistakes to Avoid

• Not comparing home loan rates from multiple lenders — a 0.25% rate difference on a ₹50L loan for 20 years saves ₹3–4 lakhs in interest.
• Choosing the maximum tenure blindly — a 30-year loan costs 40–50% more in total interest compared to a 15-year loan.
• Not factoring in stamp duty, registration, GST (for under-construction), and interior costs when budgeting for a home purchase.
• Skipping the pre-approved loan stage — knowing your eligible loan amount upfront prevents heartache during property shortlisting.

Why You Need This Calculator

Home loans in India have grown to over ₹27 lakh crore outstanding as of 2025. With property prices varying wildly — from ₹3,000/sqft in tier-3 cities to ₹50,000+/sqft in Mumbai — understanding your mortgage affordability and total cost is essential. Banks typically lend 75-80% of property value, and the interest component often exceeds the principal over long tenures.

Calculator Features

• EMI calculation with complete amortization schedule
• Stamp duty and registration cost estimation
• Home loan eligibility based on income
• Prepayment impact analysis
• Balance transfer savings calculator
• Tax benefit under Section 24B and 80C

The Math Behind It

Same as EMI formula: EMI = [P × R × (1+R)^N] / [(1+R)^N – 1]. Eligibility: Max loan = 60× monthly salary (approx). LTV ratio: 75-90% of property value.

Calculation Example

Property ₹80 lakh, 80% LTV = ₹64 lakh loan at 8.5% for 20 years. EMI = ₹55,540. Total payment = ₹1,33,29,600. Total interest = ₹69,29,600. Tax saved (30% bracket): ~₹6.9 lakh over tenure.
