Incomplete Records and Single Entry Systems

Capital investment appraisal involves evaluating long-term projects that require significant capital outlay. Students learn to use the Payback Period and Net Present Value (NPV) methods. A key concept here is the 'time value of money', the idea that a dollar today is worth more than a dollar in the future. This is a fundamental principle in finance and is essential for students to understand how large-scale projects, like Singapore's infrastructure developments, are evaluated.

Activity 01

Simulation Game60 min · Small Groups

Simulation Game: The Dragon's Den

Students pitch a long-term investment project (e.g., opening a new branch or buying a delivery fleet) to a panel of 'investors.' They must present their NPV and Payback Period calculations and answer questions about their assumptions.

Inquiry Circle30 min · Small Groups

Inquiry Circle: The Time Value Experiment

Groups are given $1,000 and two options: receive it now or in five years. They use different interest rates to calculate the 'present value' of the future cash and discuss how inflation and risk change their preference.

Think-Pair-Share25 min · Pairs

Think-Pair-Share: Payback vs. NPV

Students individually list the strengths and weaknesses of the Payback Period method. They then pair up to discuss why a project with a fast payback might still be rejected if it has a negative NPV.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • The Payback Period method considers the total profitability of a project.

    Payback only measures how quickly the initial investment is recovered; it ignores all cash flows that occur after the payback point. Peer comparison of two projects, one with fast payback but low total profit, and one with slow payback but high total profit, helps surface this error.

  • NPV and profit are the same thing.

    Profit is an accounting measure based on accruals and depreciation, while NPV is based on actual cash flows and the time value of money. Using a 'cash flow vs. profit' timeline helps students see that NPV accounts for the timing of when money actually enters or leaves the bank.
