3.8 Investment appraisal

Investment appraisal involves evaluating potential investment opportunities to determine their viability and potential returns. Three key methods are employed in this process: payback period, average rate of return, and net present value.

The payback period is a straightforward method that assesses the time it takes for an investment to recover its initial cost. It is a simple measure of liquidity and is particularly useful for businesses seeking a quick return on their investments.

The average rate of return calculates the average annual profitability of an investment over its lifespan. This method provides a percentage figure, offering insights into the overall profitability of the investment relative to its cost.

Net present value (NPV) is a more sophisticated approach, considering the time value of money. NPV calculates the present value of future cash flows generated by an investment, deducting the initial investment cost.

These methods collectively offer businesses a comprehensive toolkit. That said…..they are just the start of the process as qualitative data and information also needs to be used to gain a full picture!
