This method is superior to the payback period, but is fundamentally unsound. While it
does take account of the earnings over the entire economic life of a project, it fails to
take account of the time value of money. This weakness is made worse by the failure
to specify adequately the relative attractiveness of alternative proposals. It is biased
against short term projects in the same way that payback is biased against longer term
ones.
EvaluationTraditionally as a popular investment appraisal criterion, the accounting rate of return
has the following virtues:
l It is simple to calculate.
l It is based on accounting information which is readily available and familiar to
businessmen.
l It considers benefits over the entire life of the project.
l Since it is based on accounting measures, which can be readily obtained from the
financial accounting system of the firm, it facilitates post-auditing of capital
expenditures.
l While income data for the entire life of the project is normally required for
calculating the accounting rate of return one can make do even if complete
income date is not available. For example, when due to indeterminacy of project
life a complete forecast of income cannot be obtained, the accounting rate of
return can be calculated on the basis of income for some typical year or income
for the first three to five years.
