2. Anne wants to retire in 20 years, and she wants to have an annuity of $50,000 a year for 25 years after retirement. Anne wants to receive the first annuity payment the day she retires. Using an interest rate of 8%, the amount that Anne must invest today in order to have her retirement annuity is closest to:
Option C. A good example of a sunk cost is money that a banking corporation spent last year to investigate the site for a new office, then expensed that cost for tax purposes, and now is deciding whether to go forward with the project
A sunk cost is a cost which has already been incurred and has no effect in the evaluation of a project. The cost has been incurred and is now a sunk cost.
2. We will first find out the present value annuity of $50,000 for 25 years to find out the balance in the retirement account.
then we will find out the payment done today for that retirement fund
Present value annuity of $50,000 for 25 year @ 8% = P * [ 1 - ( 1 + r)-n ] / r
PVA = 50000 * [ 1 - ( 1 + 0.08)-25 ] / 0.08
PVA = 50000 * [ 1 - 0.146018 ] / 0.08
PVA = 50000* 0.853982 / 0.08
PVA = 533738.81
this amount is required after 20 years from today
Amount to be invested today is calculated as follows
PV = PVA / ( 1 + r )n
PV = 533738.81 / ( 1 + 0.08)20
PV = $114512.70
Anne should invest $114512.70 today for an annuity payment of $50,000 for 25 years after retirement.
