Quick Check – the payback method
iii. Evaluation of the payback method
1. Criticisms
a. A shorter payback period does not
always mean that one investment is
more desirable than another.
b. The payback method ignores cash
flows after the payback period, thus
it has no inherent mechanism for
highlighting differences in useful life
between investments.
c. As previously mentioned, the payback
method does not consider the time
value of money.
Helpful Hint: Ask students to choose between two
options that each require an initial investment of
$4,000. Option A returns $1,000 at the end of each four
years; option B returns $4,000 at the end of the fourth
year. Under the payback method, options A and B are
equally preferable. Note, however, that option A is
better, since the cash flows come earlier. Now add that
in year 5, option A will produce an additional cash
inflow of $5,000 but that option B will never generate
another dollar after the fourth year. Repeat the
question of preference of option A or B using only the
payback method. The payback method ignores the time
value of money and does not measure profitability; it
just measures the time required to recapture the
original investment.
