Reggie has just taken over management of a family business.
He wants to make sure that it makes financial sense to keep the business going.
He could sell the building today for $610,000.
Keeping the business going will require a $60,000 renovation now and will yield
an annual profit of $72,000 for the next 25 years
(for simplicity assume these occur at year end, beginning one year from now).
The interest rate is 6%. What are the NPV and IRR of this decision?
~~~~~~~~~~~~~~~~
NPV is the net present value.
In this problem, it is the difference of the present value of the given
ordinary annuity and the this year investment for renovation
NPV = PV - 60000 dollars.
For the present value PV of the annuity, use the standard formula
PV = .
Here PMT = 72,000 dollars; r = 0.06/12 = 0.005; n= 25 years. So,
PV = = = 1688085.94 dollars.
NPV = PV- 60000 = 1688085.94 - 60000 = 1,628,085.94 dollars.
You may compare it with $610,000 for selling the building now.
