To determine

Concept Introduction:

ARR:

Accounting Rate of Return (ARR) is the rate of return earned on the investment made in a project. ARR is calculated by dividing the Average Accounting profits by Average Investment.

The formula to calculate ARR is as follows:

  $ARR=\frac{AverageAccountingprofits}{AverageInvestment}$

Hence, higher the ARR better it is. A project with the Higher ARR is chosen first in the capital rationing process.

IRR:

Internal Rate of Return (IRR) is the rate at which the NPV of the project is 0 or we can say that IRR is the rate of return at which the project is at breakeven. IRR is calculated using excel or approximation method.

To Indicate:

The difference between the Average rate or return and internal rate of return
