Think of the relation between PV and interest rate as follows:
The PV (at some rate) is the amount you’d have to deposit in an account to EXACTLY duplicate the future cash flows. If you wanted a perpetuity of (for example), $10 per year and could earn 10% on your money, you’d have to deposit exactly $100. So, the pv of a $10 perpetuity at 10% is $100.
In other words, saying “the present value of a $10 perpetuity is 100 at 10% equivalent to saying “if we paid $100 to receive a $10 perpetuity, we’d be earning 10%”. So, if we paid $200 for the right to receive $10 annually, we’d be earning 5% (i.e. the pv of the perpetuity at 5% is $200). |
