Quantitative results and decision making
Quantitative results and decision-making
- When a business is deciding whether to invest in a project, the quantitative methods of payback period, average rate of return (ARR) and net present value (NPV) can help it to make an informed choice
- They are likely to set specific investment criteria
Quantitative investment appraisal criteria
| Method | Explanation | Example |
|---|---|---|
| Payback period | - A shorter payback period is usually preferred - It means the business gets its money back faster | - A firm may only accept investments with a payback period of less than 3 years |
| Average rate of return (ARR) | - The investment's return is compared to other possible uses of the money, such as placing it into an interest-paying account | - A business might set a rule that projects must achieve at least 15% ARR to be approved |
| Net present value (NPV) | - A positive NPV means an investment is financially worthwhile | - A business may only accept projects with a positive NPV above $5,000 to ensure added value |
Evaluation of quantitative methods
-
Using quantitative methods to make investment decisions has a range of advantages
- It helps reduce risk by avoiding unprofitable investments
- It makes comparisons between different projects more objective and data-driven
- It enables managers to set clear and measurable targets for investment decisions
-
However, these methods focus on financial results
- Good decisions also consider non-financial factors like environmental impact, employee wellbeing or customer satisfaction
Qualitative factors and investment decisions
- Non-financial factors can be just as important as quantitative analysis when making investment decisions
Examples of qualitative factors affecting investment decisions
| Qualitative factor | Explanation | Key question |
|---|---|---|
| Business aims and objectives | - The investment should align with the business’s overall goals (e.g. growth, sustainability, social impact) | - Does the investment support the business’s mission and long-term goals? |
| Stakeholder impact | - Consider how the investment will affect employees, customers, suppliers, and the local community | - Will it lead to job losses, new opportunities, or community disruption? |
| Environmental impact | - Projects that harm the environment may damage reputation or go against ethical values, while green projects support sustainability | - Will the project harm or protect the environment? |
| Risk tolerance | - Some businesses are more willing to take risks depending on size, finances, and confidence in the market | - Is the business willing and able to take on the level of risk involved? |
Comparison of investment appraisal methods
- Each of the methods of investment appraisal measures a different metric and is more appropriate in certain situations
- Each method also has a range of limitations of which users should be aware when using the method to make investment decisions
Comparing investment appraisal methods
| Method | What it measures | When to use It | Key limitations |
|---|---|---|---|
| Payback period | - The time it takes to recover the initial investment from cash inflows | - When the business values speed of repayment and wants to reduce risk, especially in uncertain markets | - It ignores total profitability and cash flows after payback - It does not account for the time value of money |
| Average rate of return (ARR) | - The average annual profit earned, expressed as a percentage of the investment | - Useful for comparing profitability between multiple projects - Simple for non-financial managers to understand | - It ignores timing of cash flows and the time value of money - It is based on accounting profit, not cash |
| Net present value (NPV) | - The present value of future returns minus the initial investment, using a discount rate | - Best for large or long-term investments where risk and time value of money need to be considered | - It is more complex to calculate - Results depend on the chosen discount rate - It may be harder to explain to stakeholders |
