How to Use This Mortgage Calculator

1 Select your currency – from 170+ global currencies.
2 Enter the home price – the total purchase price of the property.
3 Set your down payment – the amount you pay upfront.
4 Choose the loan amount – auto‑calculated or manually adjusted.
5 Enter the interest rate – the annual percentage rate on the mortgage.
6 Select the loan term – typically 15 or 30 years.
7 (Optional) Add extra payments – see how additional payments reduce interest and shorten the term.

The Mortgage Payment Formula

The mortgage payment formula calculates your fixed monthly payment based on the loan amount, interest rate, and loan term:

M = P × (r × (1 + r)n) / ((1 + r)n − 1) Where: M = monthly payment, P = loan principal, r = monthly interest rate, n = total number of months

For example, on a $240,000 mortgage at 7% for 30 years, the monthly payment is approximately $1,597 — and you'll pay $334,821 in total interest.

What Is Amortization?

Amortization is the process of paying off a mortgage through regular monthly payments. Each payment covers both principal (the amount borrowed) and interest (the cost of borrowing).

Early in the mortgage, most of your payment goes toward interest. Over time, as the principal decreases, more of your payment goes toward the principal. An amortization schedule shows this breakdown month by month — and this amortization calculator generates it instantly.

Frequently Asked Questions About Mortgages

1. What is the difference between principal and interest on a mortgage?
Principal is the amount you borrowed to buy the home. Interest is the fee the lender charges for lending you that money. Your monthly payment covers both — principal reduces what you owe, while interest is the cost of borrowing.
2. How does extra mortgage payment help?
Making extra mortgage payments reduces your principal faster, which lowers the total interest you'll pay and can shorten your mortgage term by years. This mortgage calculator shows you exactly how much you can save.
3. What is an amortization schedule?
An amortization schedule is a complete table showing every monthly payment over the life of the mortgage. It breaks down how much of each payment goes toward principal and interest, and shows your remaining balance after each payment.
4. How does the loan term affect my monthly payment?
A shorter loan term (e.g., 15 years) means higher monthly payments but much less total interest. A longer term (e.g., 30 years) lowers your monthly payments but you'll pay significantly more interest over time.
5. What is a good down payment for a mortgage?
A down payment of 20% is traditionally recommended to avoid Private Mortgage Insurance (PMI). However, many lenders accept as little as 5–10%. This home loan calculator lets you test different down payment amounts to see their impact.
6. Can I use this mortgage calculator for refinancing?
Yes. Enter your current home price, your remaining loan amount as the loan amount, and the new interest rate and term to see your new monthly payment and total interest — helping you decide if refinancing is worthwhile.
7. How accurate is this mortgage calculator?
This mortgage payment calculator uses the standard formula and is accurate for estimating your payments. However, actual mortgage costs may include taxes, insurance, and fees — always consult your lender for final numbers.
