Quick answer: how to calculate a mortgage payment

Borrow the price minus your down payment, then apply the EMI formula. A ₹60,00,000 home with 20% down at 8.5% for 20 years has an EMI of ₹41,655.52, with total interest of ₹51,97,323.65.

Overview of the Mortgage Calculator

A mortgage (home loan) is repaid in equal monthly instalments of principal and interest. This calculator turns the price, down payment, interest rate and term into your monthly EMI, the total interest you will pay over the life of the loan and how long it takes to clear. You can also add property tax, insurance and maintenance to see the true monthly cost of owning.

Extra payments make a big difference: adding a monthly, yearly or one-time overpayment shortens the loan and cuts interest, and the calculator shows exactly how much. The yearly schedule shows how the balance falls — in the early years most of each EMI is interest. For schedules see the Mortgage Amortization Calculator; to clear a loan early use the Mortgage Payoff Calculator.

How We Calculate

The calculator applies the standard financial formulas step by step.

  1. Convert the annual rate to a monthly rate (÷ 12 ÷ 100) and the term to months.
  2. Work out the amount you actually borrow after down payment, trade-in, fees and any financed charges.
  3. Apply the EMI formula to get the fixed monthly payment.
  4. Build the schedule month by month: interest = balance × monthly rate; principal = payment − interest.
  5. Add up the interest and payments; with extra payments, repeat the schedule to find the interest and time saved.
EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)
r = annual rate ÷ 12 ÷ 100   n = years × 12
total interest = EMI × n − P

Mortgage Calculator — Frequently Asked Questions

What is a mortgage EMI?

EMI stands for equated monthly instalment — a fixed payment that covers the interest for the month and repays part of the principal, so the loan is fully cleared by the end of the term.

How much home loan can I get?

Lenders typically cap the EMI at 40–50% of your net income and lend up to 75–90% of the property value. Use the House Affordability Calculator to see a safe limit.

Does a longer term lower the EMI?

Yes, but you pay far more interest overall. Compare the terms in the table on this page to see the trade-off.

How do extra payments help?

Every extra rupee goes straight to principal, reducing future interest. Even a small monthly top-up can cut years off a 20-year loan.

What is included in the monthly cost besides EMI?

Property tax, home insurance and maintenance or society charges. Enter them to see the total monthly outgo.

What is amortization?

The process of paying off a loan in instalments. Early payments are mostly interest, later ones mostly principal.

How is the mortgage calculator calculated?

It uses the standard formula: EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1) The full method and a worked example are shown on this page.

Is this financial advice?

No. The calculator gives estimates for planning and learning. Real offers vary by lender, product and date, so confirm the details with your bank, lender or a qualified adviser before deciding.

Can I use another currency?

Yes. The maths is identical in any currency; only the currency symbol shown in the results differs.

Is my data stored?

No. Everything is calculated in your browser and nothing you enter is uploaded or saved.
