CAPITAL INVESTMENT APPRAISAL
Inflation
Various revenues and costs rise at the same rate as general inflation.
• Where synchronized inflation is applicable, it may be easier to ignore
inflation.
• However, for exam purposes convert the real rate to a nominal rate and
adjust the cash flows for inflation.
Various revenues and costs do not all rise at the same rate as general inflation
(i.e. general inflation is 10% pa but wages increase at 20% pa).
• However, should differential inflation be applicable the rates and cash
flows must be adjusted for inflation (no choice).
NOTE: The interest rate used to discount future cash flows (WACC)
incorporates inflation (i.e. it is a nominal rate) therefore to be consistent
the cash flows should also incorporate inflation.
NB: In a question you can assume the rate and the cash flows given
include inflation unless otherwise stated.
