So here what we're implicitly trying to decide is the value of $200 ,900 today versus 500 plus 800 in the future.
00:13
And those, of course, cannot simply be compared to apple to the apples.
00:17
Money today is worth more than money in the future because money in today can be deployed to earn interest, right? it's more valuable than money in the future.
00:26
So what i want to do is calculate something called the present value of those cash flows.
00:30
With the idea being that the rate of interest determines how much money today is worth versus money tomorrow is worth.
00:37
So the present value would be based on this 500 plus this 800, but it has to adjust for how far in the future those values arrive.
00:48
So in year one, when you're receiving 500, it is worth one plus 12 % less.
00:54
We have to discount it by 12 % because if we had that 500 one year earlier, we could have earned 12 % interest...
