Mortgage Calculator
A mortgage quote hides a lot behind one monthly number. Enter the home price, deposit, interest rate and term and this calculator shows the monthly payment, how much interest you will pay over the whole loan, and the total cost — so you can compare lenders and terms on equal footing.

Frequently asked questions
How is the monthly payment worked out?
With the standard amortisation formula: payment = P × r(1+r)^n ÷ ((1+r)^n − 1), where P is the amount borrowed, r the monthly rate and n the number of payments.
Does it include taxes and insurance?
No — it covers principal and interest only. Taxes, insurance and HOA fees vary by property and are added on top by your lender's estimate.
Fixed or adjustable rate?
This calculator assumes a fixed rate for the whole term. For an adjustable-rate loan, re-run it with each expected rate to see the range.
What does a bigger deposit change?
It lowers the amount borrowed, which cuts both the monthly payment and the total interest — often by more than the deposit itself.
