Project Evaluation for Alpha and Beta- An Example

Scenario 1: Project Alpha - Non-Discounting Methods

Case A: Uniform Cash Flows

Payback Period

Initial InvestmentAnnual Cash InflowPayback Period
$100,000$30,0003.33 years

Decision: Accept the project as the payback period (3.33 years) is less than the cutoff period (4 years).

Accounting Rate of Return (ARR)

Average Annual Profit After TaxAverage InvestmentARR (%)
$10,000$50,00020%

Decision: A hurdle rate is needed to determine the acceptance of ARR.

Case B: Non-Uniform Cash Flows

Payback Period

YearCash InflowCumulative Cash Flow
1$10,000$10,000
2$20,000$30,000
3$30,000$60,000
4$40,000$100,000

Decision: Accept the project as the payback period (4 years) is equal to the cutoff period (4 years).

Accounting Rate of Return (ARR)

Total Cash InflowAverage Annual Cash InflowAverage InvestmentARR (%)
$150,000$30,000$50,00020%

Decision: A hurdle rate is needed to determine acceptance.

Total PV of Cash Inflows$629,024.64
NPV$129,024.64

Decision: Accept the project as the NPV is positive ($129,024.64).

Profitability Index (PI)
