⚖️ Payback vs ARR

Both methods have strengths — and they often give different recommendations. A smart business uses both.


  • Payback tells you how QUICKLY you get your money back (focuses on risk and cash flow)
  • ARR tells you how PROFITABLE the investment is overall (focuses on return)
  • A project with a short payback but low ARR recovers cash fast but isn't very profitable
  • A project with a long payback but high ARR is more profitable but ties up cash longer
Example: Project X — Payback: 2 years, ARR: 8%. Project Y — Payback: 4 years, ARR: 18%. A cash-strapped start-up might choose X. A well-funded business might choose Y for the higher return.

💭 Qualitative Factors

Numbers alone don't make the decision. Managers must also consider non-financial factors that can't be captured in calculations.


  • Corporate objectives — does the investment align with the business's strategy?
  • Risk and uncertainty — how reliable are the cash flow predictions?
  • Environmental and ethical impact — will it harm the environment or reputation?
  • Staff implications — will jobs be created or lost?
  • Market conditions — is demand likely to grow or shrink?
  • Competitor actions — are rivals investing in similar things?
The 'best' investment on paper isn't always the best decision in practice. Qualitative factors can tip the balance! 🧠

🎯 Making a Recommendation

In the exam, you may be asked to recommend which investment to choose. Here's a proven structure:


  • Step 1: Calculate payback AND ARR for each option
  • Step 2: Compare the quantitative results — which option is better on each measure?
  • Step 3: Consider qualitative factors — risk, strategy, ethics, market conditions
  • Step 4: Make a clear recommendation — state WHICH option and WHY
  • Step 5: Acknowledge limitations — the forecast could be wrong, results depend on assumptions
A recommendation WITHOUT justification scores poorly. Always explain your reasoning — even if you pick the 'obvious' choice, the examiner wants to see WHY! 📝
