The risks associated with business investments

Investing carries inherent risks, as there is no guarantee that the expenditure will lead to increased income. In some cases, it may even result in financial losses if the investment fails to deliver expected benefits. To mitigate these risks, businesses assess potential investments to determine if they are likely to be worthwhile.

How to calculate the average rate of return (ARR)

The return on an investment measures the gain or loss as a proportion of the original amount invested. A key tool for this is the average rate of return (ARR), which calculates the average yearly return over the investment's lifespan—the period during which it generates income for the business.

Formula for average annual profit

$\text{Average annual profit}=\frac{\text{total profit}}{\text{number of years}}$

Where:

• Total profit = Overall profit generated by the investment (£)
• Number of years = Lifespan of the investment

Formula for ARR

$\text{ARR (\%)}=\frac{\text{average annual profit}}{\text{cost of investment}}\times 100$

Where:

• Average annual profit = Profit per year on average (£)
• Cost of investment = Initial amount invested (£)

Worked example - Calculating ARR

A business invests £60,000 in new equipment that generates a total profit of £21,600 over 6 years. Calculate the ARR for this investment.

Step 1: Identify the values

• Cost of investment = £60,000
• Total profit = £21,600
• Number of years = 6

Step 2: Calculate average annual profit

$\text{Average annual profit}=\frac{\pounds \mathrm{21,600}}{6}=\pounds \mathrm{3,600}$

Step 3: Calculate ARR

$\text{ARR (\%)}=\frac{\pounds \mathrm{3,600}}{\pounds \mathrm{60,000}}\times 100=6\%$

Evaluating ARR results

A higher ARR indicates a more successful investment, as it reflects greater returns relative to the cost. However, what constitutes a strong ARR varies depending on the business context and the scale of the investment.

For example, an 8% ARR might represent substantial value for a £500,000 investment but could be less impressive for a £200 outlay. There is no universal threshold for a good ARR; it must be judged based on individual circumstances.
