The calculator is for illustrative purposes only and does not provide a precise calculation.

Extending your mortgage term will make your monthly payments smaller. But it’ll also increase the amount of interest you have to pay overall.

Reducing your mortgage term means your payments are higher each month. But the overall amount of interest you’ll have to pay will be less. 

The figures produced by this calculator are based on the information that you provide (i.e. mortgage amount, interest rate and term) and assumes that the interest rate remains the same for the term of your mortgage and doesn't include any change of interest rate during the length of the mortgage.
