So the next question is how do you find the present value of future cash flows? now when you want to answer this question, it is not straightforward because to get present values of future cash flows, the cash flows themselves have to be defined.
00:21
Are they uniform or they vary from period to period? if they are a uniform one, meaning to say they are an annuity, to find the present value of an annuity, you will have to find that value, let's call it c for cash flow, and then you have one minus, then one plus i to the power n to the power n, then you close, then all of which is to the power and all of it all over i.
01:20
So i representing interest.
01:23
So we can define our variables as follows.
01:32
So we can see c is cash flow, which is an annuity.
01:39
And then n is the number of periods where the cash flow is spreading, and then i is always the effective interest, which is always in a percentage format...
