25.5 Compare and Contrast Non-Time-Value-Based Methods and Time-Value-Based Methods

Non-Time-Value-Based Methods​

  1. Payback Period

    • Focus: Liquidity
    • Pros: Simple, highlights risk
    • Cons: Ignores time value and cash flows after payback
  2. Discounted Payback Period (hybrid)

    • Accounts for time value but still ignores post-payback cash flows
  3. Accounting Rate of Return (ARR)

    • Focus: Accounting profitability
    • Pros: Uses familiar accounting data
    • Cons: Ignores time value, uses accounting profit not cash flow

Time-Value-Based Methods​

  1. Net Present Value (NPV)

    • Focus: Value creation
    • Pros: Considers time value, cash flows, risk
    • Cons: Requires accurate discount rate
  2. Internal Rate of Return (IRR)

    • Focus: Rate of return
    • Pros: Intuitive, considers time value
    • Cons: Multiple IRRs possible, reinvestment assumption
  3. Profitability Index (PI)

    • Focus: Value per unit of investment
    • Pros: Useful for capital rationing
    • Cons: May conflict with NPV when comparing mutually exclusive projects
  4. Discounted Payback

    • Focus: Liquidity with time value
    • Pros: Considers risk and time value
    • Cons: Ignores cash flows after payback

Decision Framework​

  • Use payback/ARR for quick screening
  • Use NPV/IRR/PI for final decisions
  • Use discounted payback to assess risk/liquidity
  • Consider qualitative factors throughout

Luxembourg Compliance Note​

In Luxembourg, SMEs often start with simple methods (payback, ARR) but banks and investors will expect NPV and IRR analysis for financing decisions. Capital budgeting analysis should also include sensitivity and scenario testing given market volatility.

Think It Through​

Can a project have a positive NPV but fail the payback test? Should it be accepted? Why or why not?
