Using the Net Present Value (NPV)

  • The Net Present Value (NPV) takes into account the effects of interest rates and time

  • It recognises

    • The fact that that money received in the future is often worth less than money received today (inflation)

    • The opportunity cost of not having the money available for other uses

  • To calculate the Net Present Value of an investment, the value of all future net cash flows in today’s terms need to be calculated first and then discounted using a table

  • The cost of the initial investment is deducted from the total of the discounted net cash flows

    • If future net cash flows minus the initial investment are positive, then the investment is likely to be worthwhile

    • If the sum of future net cash flows minus the initial investment is negative, then the investment is unlikely to be worthwhile

  • Discounted cash flows are calculated using discount tables, which allow future cash flows to be expressed in today’s terms

Worked Example

Brownsea Sightseeing Tours Ltd is considering purchasing a new pleasure craft at a cost of £325,000.  It expects the investment to achieve the following net cash flows over five years of operation

Using the 10% discount factor calculate the NPV of the leisure craft investment. (4 marks)

 

Step 1 - Calculate the discounted cash flow for each year by multiplying the net cash flow by the discount factor

Step 2: Add together the discounted cash flow values for each year, including Year 0

The Net present Value of the investment is -£12,550

This negative outcome suggests that the investment in the new pleasure craft is not financially worthwhile

Advantages and Disadvantages of the Net Present Value Method

Advantages

Disadvantages

  • Considers the opportunity cost of money

  • Discount tables are used to calculate forecast future values of net cashflows

  • Businesses may choose different discount tables (20%, 10%, 5% etc)  to adjust the level of risk involved in a project

    • Can consider a range of scenarios

  • More complicated to calculate and interpret than other methods
     

  • Accurately forecasting future cash flows is complex

  • Choosing an appropriate discount rate can be 'hit and miss'

  • Ignores non-financial benefits or costs e.g environmental damage

Exam Tip

Being able to calculate the payback period, ARR or NPV of an investment is a key quantitative skill

More important, though, is interpreting the outcome of your calculation and using it to make a judgement

  • Is an investment worthwhile?

  • Which investment is the most profitable?

  • The costs of which investment will be recouped first?

Qualitative factors should be considered alongside calculations - review case study material carefully to select relevant information

Limitations of using Investment Appraisal

  • Each techniques relies upon forecasted future cash flows which may lack accuracy

    • Managers may lack experience or may be biased towards a particular investment

    • Incomplete past data may make forecasting imprecise or mean that confidence in the data is limited
       

  • Longer-term forecasts used to predict returns on investments may be inaccurate for a variety of reasons

    • Unexpected increases in costs

    • The arrival of new competitors

    • Changes in consumer tastes

    • Uncertainties arising as a result of economic growth or recession

  • Non-financial factors are ignored

    • Business finances and availability of external finance to fund the investment

    • Overall corporate objectives 

    • Potential for positive public relations or meeting social responsibilities
