Are you exploring interest-only mortgage options for your home loan? Want to know what your monthly payments will look like during the interest-only period? Use our Interest-Only Mortgage Calculator to easily estimate your payments and understand how this type of loan fits into your financial plan.

Whether you’re a first-time homebuyer, investor, or refinancing an existing mortgage, this tool offers clarity and speed in calculating your interest-only payments.

💡 What Is an Interest-Only Mortgage?

An interest-only mortgage allows you to pay only the interest on your home loan for a specified period (usually 5 to 10 years). During this initial phase:

• You do not pay toward the principal
• Monthly payments are lower
• After the interest-only period, you begin paying both interest and principal, which increases your monthly payments

This structure offers short-term affordability — but it’s important to know what your payment plan looks like before the higher payments kick in.

🧮 Formula Behind the Calculator

Here’s how we calculate monthly interest-only payments:

javaCopyEditMonthly Interest Payment = (Loan Amount × Annual Interest Rate) ÷ 12

Let’s say:

• Loan = ₹50,00,000
• Interest Rate = 7%
• Term = 5 years

Your monthly payment = (50,00,000 × 0.07) ÷ 12 = ₹29,167

Total interest paid in 5 years = ₹29,167 × 60 = ₹17,50,000
