How do you work this out? And how do you put it in the Calculator?

Question

You have been offered an annuity over twenty periods with payments of $5,000 at a rate of 12% per period. How much would you have to invest now at the same rate to obtain the same amount of money at the end of the twentieth period??

I think its (1.12)^20 but how do you put that into a texas instrument calculator??

Answer 1

What do you mean by "the same amount of money at the end of the twentieth period"?

Do you mean having the same principle i.e. this is a perpetuity?

In Excel: PV=PV(12%,20,-5000,Guess)

I get $41,666.67.
