What To Discount
Points to “Watch Out For”
Estimate Cash Flows on an Incremental Basis
Do not confuse average with incremental payoffs
Include all incidental effects
Do not forget working capital requirements
Include opportunity costs
Forget sunk costs
Beware of allocated overhead costs
Treat inflation consistently

INFLATION RULE
Be consistent in how you handle inflation!!
Use nominal interest rates to discount
nominal cash flows.
Use real interest rates to discount real cash
flows.
You will get the same results, whether you
use nominal or real figures
7- 6
Inflation
Example
You own a lease that will cost you $8,000 next
year, increasing at 3% a year (the forecasted
inflation rate) for 3 additional years (4 years
total). If discount rates are 10% what is the
present value cost of the lease?
1+ nominal interest rate
1  real interest rate =
1+inflation rate

Equivalent Annuities
Example (with a twist)

were asked to calculate the equivalent annual annuity on a
series of cash flows with a positive NPV. Which project would
you select with the following cash flows and a 9% discount rate?
