🔎 Accounting Rate of Return

In general, we don’t like ARR because it doesn’t respect the time value of money. Therefore, we won’t spend much time on it.

To some degree, this slide is here to remind us that it is important to account for the Time Value of Money.

Accounting Rate of Return

ARR comes down to two equations:

ARR=Average profits after taxesAverage investmentARR=\frac{\text{Average profits after taxes}}{\text{Average investment}} Average profits after taxes=Average annual operating cash inflowsAverage annual depreciation\text{Average profits after taxes}=\text{Average annual operating cash inflows} - \text{Average annual depreciation}

❔ What was Apple’s ARR. You have the opportunity to lease “Apple” for 3 years for and annual cost of $233B per year. Assume that Apple’s annual operating cash inflows are $102,288 on average and Apple’s total annual depreciation is $11,148 on average.

Average Profits After Taxes=Av Ann Operating Cash InflowsAv Ann Depreciation=102,28811,148=91,140\text{Average Profits After Taxes} = \text{Av Ann Operating Cash Inflows} - \text{Av Ann Depreciation} = 102,288 - 11,148 = 91,140

ARR=Avg Profit Aft TaxAvg Investment=91,140233,000=0.3912ARR = \frac{\text{Avg Profit Aft Tax}}{\text{Avg Investment}} = \frac{91,140}{233,000} = 0.3912
