Ask the Tutor ACCA MA

Annuities And perpetuities in arrears.

AAlby3y ago
Sir, Could you please assist me with this question, What is the PV of $200 incurred each year for four years, starting in three years' time, if the discount rate is 5%? Soln: PV of cash inflow (under perpetuity)= Annual cash inflow × 1÷R = 200×1÷0.05 = 200÷0.05= $4000 Sir, Could you please tell me whether it is correct or not?

No, it is not correct. Multiplying by 1/r gives the present value when the first flow is in 1 years time and only when the flows are in perpetuity. Here, there is a four year annuity that starts in 3 years time. I do explain exactly how to deal with this in my free lectures on discounting, and you cannot expect me to type out my lectures again here :-) The lectures are a complete free course for Paper MA and cover everything needed to be able to pass the exam well.
