This lesson examines the payback period method and its discounted variant. It covers the calculation, decision rules, advantages, and significant limitations of these techniques, which are covered in introductory and advanced corporate finance curricula.

• The Payback Period Method: The payback period is the time required for a firm to recover its original investment from the project’s cash inflows. The decision rule is to accept a project if its payback period is less than a predetermined maximum period set by management.

• Calculation: The payback period is calculated by dividing the initial investment by the annual cash inflow (assuming even cash flows). For uneven cash flows, it is determined by cumulative cash flows.

• Advantages of Payback Period: Despite its simplicity, the payback method continues to be used because it:

  • Provides useful information about a project’s liquidity and risk

  • Is easy to calculate and understand

  • Is particularly useful for evaluating projects where liquidity is a primary concern

• Limitations of Payback Period: The payback method has significant drawbacks:

  • It ignores the time value of money

  • It ignores cash flows that occur after the payback period

  • It does not provide a measure of profitability

  • The Saylor Academy BUS105 study guide notes that “this method has significant disadvantages. It doesn’t take the time value of money into account at all. It also ignores cash inflows that are to occur subsequent to the payback period”.

• Discounted Payback Method: The discounted payback method addresses the time value of money limitation by discounting cash flows before calculating the payback period. The Coursera Corporate Finance & Capital Budgeting course includes a module on the discounted payback period, noting that it improves on the traditional method by incorporating the time value of money.
