Common Questions About Capital Budgeting
Over the years, we've noticed businesses often struggle with the same aspects of capital budgeting. These questions come up in nearly every consultation we have with clients across Queensland and beyond.
Net Present Value (NPV) tells you the dollar amount your project will add to company value. It discounts future cash flows back to today's dollars using your required return rate. A positive NPV means the project creates value.
Internal Rate of Return (IRR) shows the percentage return you'll earn on the investment. It's the discount rate that makes NPV equal zero. Most businesses find NPV more reliable because it assumes you reinvest cash flows at your actual cost of capital, not at the IRR itself.
Your discount rate should reflect what investors expect to earn. For most businesses, the Weighted Average Cost of Capital (WACC) works well. It combines your cost of debt and equity based on their proportions in your capital structure.
If you're evaluating a project riskier than your typical operations, you might add a risk premium. Conservative approaches sometimes use the cost of equity alone, which gives a higher hurdle rate and builds in safety margin.
No. Sunk costs are already spent and won't change regardless of your decision. Including them distorts your analysis.
Say you spent $50,000 on market research last year. That money's gone whether you proceed with the project or not. Only consider costs and revenues that differ between your alternatives. This keeps your focus on what actually matters for the decision ahead.
When comparing a five-year project to a ten-year project, standard NPV calculations can mislead. The longer project naturally accumulates more cash flows.
Use the Equivalent Annual Annuity (EAA) method instead. It converts each project's NPV into an annual amount. Then you're comparing apples to apples. This approach also works well when you plan to replace equipment repeatedly over time.
Perfect accuracy is impossible. What matters is building reasonable estimates and understanding sensitivity. Run scenarios with optimistic, realistic, and pessimistic assumptions.
Focus most on variables that significantly impact NPV. Small changes in revenue growth or operating margins often matter more than precise estimates of initial equipment costs. Many businesses find that identifying key assumptions beats chasing precision in every line item.
Payback period works as a quick screening tool or when liquidity is critical. If you need cash back fast, knowing a project recovers costs in two years versus five years matters.
But payback ignores cash flows after the payback point and doesn't consider time value of money. Use it alongside NPV and IRR, not instead of them. We've seen businesses reject valuable long-term projects because they focused solely on payback.
Numbers don't tell the whole story. Strategic fit, competitive positioning, and risk tolerance all matter. Some projects open doors to future opportunities that aren't easily quantified.
Environmental impact and workforce considerations increasingly influence capital decisions too. The best approach combines rigorous financial analysis with thoughtful assessment of factors that don't fit neatly into spreadsheets.
Stay consistent. Use either nominal cash flows with nominal discount rates or real cash flows with real discount rates. Mixing them creates errors.
Most businesses find nominal easier because revenues and costs naturally come in nominal terms. Just make sure your discount rate includes an inflation component. For Australian projects, the Reserve Bank's inflation target provides a reasonable baseline for long-term planning.
