About This Calculator
The Mortgage Interest Calculator helps you estimate the total interest you will pay over the life of your home loan. By entering your loan amount, annual interest rate, and loan tenure, you get an instant breakdown of your monthly payment, total interest payable, and total amount due. The calculator uses the standard amortization formula (EMI-based) to provide accurate results.
Understanding your mortgage interest is crucial for financial planning -- it often represents a significant portion of your total repayment. A ₹50,00,000 loan at 8.5% for 20 years, for example, results in over ₹55,00,000 in total interest alone. This tool helps you compare different loan tenures and interest rates to find the most cost-effective option for your budget.

Frequently Asked Questions
How does the Mortgage Interest Calculator work?
Enter your loan amount, annual interest rate, and loan tenure in years. The calculator uses the standard amortization formula to compute your monthly payment, total interest payable over the loan term, and total amount payable. An amortization schedule shows how much principal and interest you pay each year.
What factors affect my total mortgage interest?
Your total mortgage interest depends on three main factors: the loan amount (principal), the annual interest rate, and the loan tenure. A higher principal or rate increases total interest, while a longer tenure spreads payments but also increases total interest paid over the life of the loan.
How can I reduce mortgage interest payments?
You can reduce total mortgage interest by choosing a shorter loan tenure, making a larger down payment, shopping for lower interest rates, making extra principal payments, or refinancing when rates drop. Bi-weekly payment schedules also reduce interest by making one extra monthly payment each year.
What is the difference between mortgage interest rate and APR?
The interest rate is the annual cost of borrowing the loan principal, while APR (Annual Percentage Rate) includes both the interest rate and additional fees like origination fees, discount points, and closing costs. APR gives a more complete picture of your total borrowing cost.
Is this mortgage interest calculator free to use?
Yes, it is completely free to use with no registration required. You can also share your calculation by copying the URL, which saves all your input values.
How is monthly mortgage payment calculated?
Monthly mortgage payment is calculated using the standard amortization formula: M = P x r(1+r)^n / ((1+r)^n - 1), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments (tenure x 12).
What are typical mortgage rates in India, US, and UK?
In India, mortgage rates typically range from 8-10% for home loans from banks and housing finance companies. In the US, 30-year fixed mortgage rates vary between 6-8% depending on market conditions. In the UK, mortgage rates range from 4-6% for standard residential mortgages. Rates vary based on credit score, loan-to-value ratio, and lender policies.
