Formula for Repayment Mortgage needed?

Hi

I am trying to work out the difference in what I will be paying back for an IOM or Repayment - I have worked out what the total amount is for the IOM but what is the formula for working out the total interest on a Repayment Mortgage (hope this makes sense)??

  • Yes - I have got excel
  • the funtion you need to use is the pmt funtion,

    which will ask for rate, Nper, and pv.

    You will need to decide on whether you are going to use daily interest, monthly interest, or annual interest for your calculation -

    Annual

    rate is your interest rate (but remember it is a %, so 5% is 0.05), Nper is your number of payments= 25 (years) and pv = present value (loan size)

    Monthly

    rate = rate/12
    term = term*12
    pv = loan

    Using £100,000 over 25 years at 5% you will get

    Annual = 7095.25 (then divide this by 12 to get monthly figure = 591.27
    Monthly = 584.59

    (in fact, you get a minus figure, you just need to reverse the signs.)

    If you want total cost, then you just need to multiply by total payments (so for a 25 year term mortgage = 300)

    If this doesn't make sense then let me know

    :)

  • Thanks MM - I did it.

    Excel is a great thing, I just seem to learn more and more about it, it seems never ending.

    Thanks again
