    Hello Sir,

    Question 4 in the test questions asks for the present value of $2000 per annum first receivable in 3 YEARS,but the solutions at the end of the notes calculates the first receipt after 2 YEARS.
    Please could you shed more light on this and give clarity as to why they are different using the different number of years gives different answers. Or am I missing something or got something wrong somewhere? Please help.

    Many thanks.

    Hey John, in annuity, i just wanted to knew if there was an easier way of calculating the
    “total Annuity discount factor” i kind of calculate each and every year one by one and then total them all, it is really lengthy and exhausting. any idea? and thanks the lectures are just awesome!

    Hi John,
    Quick question about perpetuities. I know how to calculate a perpetuity that starts now, but in a practice exam it said that payments would begin in 4 years time. Do I need to discount for years 1-3 and if so, how would I do that?

    Thanks for your help.

      There two ways that both give the same answer.

      Either use 1/r for the perpetuity, and then discount for a further three years using the normal discount factor for three years.


      Use 1/r for the perpetuity, and then subtract the three year annuity discount factor ( so as to be left with 4 to infinity)

      Both will give the same answer. (Except for rounding difference)
