The loan amount is the property price minus the down payment. The monthly payment uses the fixed-rate formula M = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where r is the annual rate ÷ 12 and n is the term in months. Results are estimates — taxes, insurance, fees and lender terms can change your actual cost.

What is the Mortgage Calculator?

What the tool does, who it is for and what it cannot tell you.

A mortgage calculator estimates the regular payment on a loan used to buy a property. It takes the price, your down payment, the interest rate and the loan term, and shows the monthly payment, the total you repay and how much of that is interest.

Your down payment is the part of the price you pay upfront. A larger down payment means a smaller loan, a lower monthly payment and less total interest.

Each payment covers interest on the remaining balance plus some principal. Early on most of the payment is interest; over time the principal share grows as the balance shrinks.

How does the Mortgage Calculator work?

Each step the calculator runs, in plain language.

  1. 1

    Enter price and down payment

    The loan amount is the price minus the down payment.

  2. 2

    Set rate and term

    Use the annual fixed rate and the term in whole years.

  3. 3

    Read the estimate

    See the monthly payment, totals and the principal vs interest split.

Mortgage Calculator formula

The exact maths behind every number on this page.

M = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)

M
Monthly payment (principal + interest)
P
Loan amount = property price − down payment
r
Monthly rate = annual rate ÷ 12 ÷ 100
n
Number of monthly payments = term in years × 12

Mortgage Calculator calculation example

Hypothetical example: a 400,000 property with 80,000 down, 6.5% interest over 30 years.

  1. 1Loan amount400,000 − 80,000 = 320,000
  2. 2Monthly rate / payments6.5% ÷ 12 ≈ 0.5417%; 30 × 12 = 360
  3. 3Monthly payment≈ 2,022.62
  4. 4Total interest≈ 2,022.62 × 360 − 320,000 ≈ 408,144

About 2,023 a month, with roughly 408,000 paid in interest over the term.

Important assumptions

What this calculation includes, and what it leaves out.

  • Fixed interest rate for the whole term, with monthly payments.
  • Excludes property taxes, insurance, mortgage insurance, fees, closing costs and prepayments.
  • Amounts are shown without a currency symbol; enter values in your own currency. Actual lender figures may differ.

Financial tips

Practical guidance to act on your result.

  • Compare terms: a shorter term raises the monthly payment but usually cuts total interest sharply.
  • Ask lenders for the full cost, including fees and insurance, not just the rate.
