Generally all depreciation methods allocated the cost of the equipment (less salvage value)
over some assigned useful life. While the depreciation charges in any year may be different

for different methods, the sum of the depreciation charges will be the same. This will affect
the amount of taxes paid in any year, but with a stable income tax rate, the total taxes paid
will be the same. (The difference is not the amount of the taxes, but their timing.)

Let ia = annual effective after-tax cost of capital.
XYZ, Inc. is paying:

Will the firm obtain a 6% after tax rate of return?
PW of Cost = PW of Benefits
\$120,000 =\$26,700(P/A, i%, 8)-\$3,000(P/G, i%, 8)+\$12,000(P/F, i%, 8)
At i = 6%
PW of Benefits

=\$26,700(6.210)-\$3,000(19.842)+\$12,000(0.6274)
= \$113,810
i is too high
Therefore, the firm will not obtain a 6% after-tax rate of return.

After-Tax Rate of Return = 34.3%
The purchase of the special tools for \$20,000 cash plus an \$80,000 loan represents
a leveraged situation.
Under the tax laws all the interest paid is deductible when computing taxable
income, so the after-tax cost of the loan is not 10%, but 5.4%. The resulting rate of
return on the \$20,000 cash is therefore much higher in this situation.
Note, however, that the investment now is not just \$20,000, but really \$20,000 plus
the obligation to repay the \$80,000 loan.
