Remaining balance over time

How the home loan EMI calculator works

A home loan is usually the largest and longest loan most people take on, so small changes in rate or tenure move the numbers a lot. Each monthly EMI splits between the interest charged on the outstanding balance and the principal that reduces it. Because the balance starts high, the early years are interest heavy, which is why the balance chart above falls slowly at first and faster toward the end.

The calculator uses the standard amortization formula and then works through the loan month by month. That lets it total the interest precisely and plot exactly how much you still owe at the end of each year over the full tenure.

A quick example

Take a $300,000 home loan at 7% over 30 years. The monthly EMI is about $1,996. Across the full term you repay roughly $718,000, of which around $418,000 is interest. Cutting the tenure to 20 years raises the EMI but saves well over a hundred thousand dollars in interest.

Things to keep in mind

This is an estimate of principal and interest only. Your real housing cost may also include property tax, insurance and other fees, and your rate depends on credit and lender. For guidance on shopping for a home loan, see the Consumer Financial Protection Bureau. To add taxes and insurance, try our mortgage calculator or browse our other free calculators.

Frequently asked questions

How is a home loan EMI calculated?

Home loan EMI uses the formula EMI = P·r(1+r)^n / ((1+r)^n − 1), where P is the loan amount, r is the monthly interest rate (annual rate divided by 12 and by 100) and n is the number of monthly payments. It gives a fixed monthly amount that clears the loan over the chosen tenure.

Why is so much of my early EMI just interest?

Interest is charged on the outstanding balance, which is highest at the start. So in the early years most of each EMI covers interest and only a small part reduces the principal. As the balance falls over time, more of every payment goes toward principal.

Should I choose a longer or shorter tenure?

A longer tenure lowers your monthly EMI, which helps cash flow, but you pay much more total interest because the balance stays outstanding longer. A shorter tenure raises the EMI but saves a large amount of interest over the life of the home loan.

Can prepaying my home loan save money?

Yes. Because home loans run for many years, extra payments toward principal, especially early on, cut the balance that interest is charged on and can save years of payments. Check whether your lender charges prepayment fees before you start.
