This calculator is designed to be played with - enter
your interest rate and guess how much you expect to pay each month to
pay the loan off over 25 years.
Try different numbers until you get a number in year
24 and a zero in 25. (At this point it means that your mortgage will
terminate during the last year).
Then put in the maximum you might be able to pay each
month into the calculator and see what a difference it makes to the overall
payment and time taken to buy your house.
In practice you do not have to commit to this higher
amount every month - simply setting money aside and putting it in as
a capital reduction when you can spare it will have the same effect.
(This may be of particular note to those who have special deals that
penalise early capital repayment).
Note - surprisingly small accelerated payments can shorten
the mortgage by several years and lead to savings of thousands of pounds.
