Advantages and Limitations of Both Methods

Payback Period

AdvantagesLimitations
Easy to calculate and understandIgnores all cash flows after the payback period
Emphasises early cash flows, which are more likely to be accurate estimatesIgnores the time value of money (unlike NPV)
Ideal for high-technology or fashion projects where obsolescence is a riskIgnores the timing of cash flows within the payback period (e.g. does not distinguish whether Year 1 cash flow is high or low)
Highlights liquidity — useful for businesses that need to recover funds quicklyIgnores inflation
Widely used in practiceRelies on estimated future information, which may be wrong
Ignores the total length of the asset's life
Does not consider the weighting of receipts — one project may have higher early inflows than another

Net Present Value (NPV)

AdvantagesLimitations
Considers the time value of money — unlike paybackMore complex to calculate than payback
Considers all cash flows over the whole life of the assetThe cost of capital (discount rate) is difficult to ascertain accurately and may vary over time
Takes into account the timing of cash flowsThe meaning of NPV is not always clear to non-accountants
Once discount factor tables are available, calculations are relatively straightforwardThe project with the higher NPV may not produce the best quality output
Relies on estimated future information, which may be wrong — especially for long-term projects

Using Both Together

A business may require a project to satisfy both criteria before proceeding:

  • Maximum payback period (e.g. no more than 4 years)
  • Positive NPV at the required rate of return

A project that fails either criterion would be rejected. When two projects conflict (different payback rankings vs NPV rankings), NPV is generally considered the more robust method because it accounts for the time value of money.
