Investment Appraisal
1.8 Investment Appraisal
Businesses often face decisions about whether to invest in new projects, machinery, technology, or expansion. These decisions involve large financial commitments, so managers must evaluate whether the investment will generate sufficient returns. The process of evaluating potential investments is known as investment appraisal.
Payback Period
Measures how long it takes for an investment to recover its original cost.
Payback Period = Initial Investment ÷ Annual Cash Inflow
Example: A company invests $20,000 in new machinery generating $5,000 profit per year. Payback = 20,000 ÷ 5,000 = 4 years.
Advantages: Simple and easy to calculate, useful for businesses with limited cash. Limitations: Ignores profits after the payback period, does not consider the time value of money.
Average Rate of Return (ARR)
Measures the profitability of an investment relative to its cost.
ARR = (Average Annual Profit ÷ Initial Investment) × 100
Example: Initial investment = $50,000; Average annual profit = $10,000; ARR = (10,000 ÷ 50,000) × 100 = 20%
Advantages: Considers overall profitability, easy to compare different investments. Limitations: Does not consider the timing of cash flows.
Net Present Value (NPV)
NPV is a more advanced investment appraisal technique that considers the time value of money — money received today is worth more than money received in the future.
NPV = Present Value of Cash Inflows − Initial Investment
If NPV is positive, the investment is financially worthwhile. If NPV is negative, the investment should usually be rejected. Although NPV provides more accurate results, it is more complex to calculate.
