EAC (Advance) ExampleConsider a Dentists office; he needs an autoclave to sterilize
his instruments. He has an old one that is in use, but themaintenance costs are rising and so is consideringreplacing this indispensable piece of equipment.
New Autoclave
Cost = $3,000 today, Maintenance cost = $20 per year
Resale value after 6 years = $1,200
Total PV of Costof new autoclave (at k = 10%) is $2,409.74

Resale 900 850 775 700 600 500
Total Annual CostTotal Cost for year 1 = (900 1.10850) + 200 = $340340 435Total Cost for year 2 = (850 1.10775) + 275 = $435
478
Total Cost for year 3 = (775 1.10700) + 325 = $478620
Total Cost for year 4 = (700 1.10600) + 450 = $620Total Cost for year 5 = (600 1.10500) + 500 = $660
660
Note that the total cost of keeping an autoclave for the first year includes the $200
maintenance cost as well as the opportuni ty cost of the foregone future value of the
$900 we didnt get from selling it in year 0 less the $850 we have if we still own it at
year 1.

We should keep the old autoclave until its cheaper to buy
a new one.
Replace the autoclave at the end of year 3: at that point the
new one will cost $553.29 for the next years autoclaving
and the old one will cost $620 for one more year.

Inflation and Capital Budgeting
Inflation is an important fact of economic lifeand must be considered in capital budgeting.
Consider the relationship between interest rates and inflation,often referred to as the Fisher relationship:
(1 + Nominal Rate) = (1 + Real Rate) (1 + Inflation Rate)
For low rates of inflation, this is often approximated as
Real Rate Nominal Rate Inflation Rate
When considering inflation in capitalbudgeting, one must compare real cash flowsdiscounted at real rates or nominal cash flowsdiscounted at nominal rates.

Example of Capital Budgeting underInflation
Sony International has an investment opportunity to produce anew stereo color TV.
The required investment on January 1 of this year is $32million. The firm will depreciate the investment to zero usingthe straight-line method. The firm is in the 34% tax bracket.
The price of the product on January 1 will be $400 per unit.The price will stay constant in real terms.
Labor costs will be $15 per hour on January 1. It will increaseat 2% per year in real terms.
Energy costs will be $5 per TV; they will increase 3% per yearin real terms.
The inflation rate is 5% Revenues are received and costs arepaid at year-end.

Example of Capital Budgetingunder Inflation
The project NPV can now be computed asthe sum of the PVof the cost, the PVof therisky cash flows discounted at the risky
rate and the PVof the risk-free cash flowsdiscounted at the risk-free discount rate.
NPV=$32,000,000 + $69,590,868 + $9,873,315 =
$47,464,183
