Cost-benefit analysis (CBA) - definition & overview

Cost Benefit Analysis helps individuals and businesses make informed decisions by providing a structured framework to evaluate alternatives. It aims to determine whether the projected benefits outweigh the costs, ultimately indicating if a course of action is worthwhile.

What does a cost-benefit analysis typically involve?

• Identifying all relevant costs and benefits, both tangible (financial) and intangible (non-financial).
• Assigning a monetary value to the quantifiable costs and benefits whenever possible.
• Comparing the total benefits against the total costs to determine if the option creates net positive value.
• Considering alternative options and conducting a comparative analysis.

What are the benefits of doing a cost-benefit analysis?

• Provides a data-driven approach to decision-making, reducing reliance on intuition or bias.
• Simplifies complex choices by clearly outlining the potential costs and benefits.
• Uncovers hidden aspects by prompting a comprehensive analysis of all potential impacts.

What are the limitations of a cost-benefit analysis?

• Difficulty in accurately predicting all future variables and outcomes.
• Reliance on accurate data to avoid skewed results.
• Can be less effective for long-term projects with high uncertainty.
• May struggle to assign a dollar value to intangible benefits or costs.

Overall, cost-benefit analysis is a valuable tool for informed decision-making across various sectors in Australia.

Cost-benefit analysis example

Upgrading Delivery Vehicles for a Sydney Bakery

Business: Le Pain Doré, a small bakery located in Sydney

Decision: Upgrading from two older delivery vans to two fuel-efficient hybrid vans.

Costs:

• Financial:
  • Purchase cost of two new hybrid vans: AU$80,000
  • Disposal costs of old vans: AU$2,000
  • Potential maintenance cost increase (due to newer technology):  AU$1,000 per van annually
• Non-financial:
  • Training staff on operating new vans
  • Downtime during the transition to new vehicles (potential loss of sales)

Benefits:

• Financial:
  • Reduced fuel costs (estimated 30% decrease)
  • Potential tax benefits for environmentally friendly vehicles
  • Increased delivery capacity with larger cargo space (potentially leading to more sales)
  • Lower maintenance costs in the long run (due to hybrid technology)
• Non-financial:
  • Improved brand image due to focus on sustainability
  • Enhanced employee morale with newer, more comfortable vehicles
  • Reduced environmental impact

Analysis:

• The initial investment (purchase and disposal) is AU$82,000.
• Potential annual fuel cost savings could be substantial, depending on fuel prices. Let's assume AU$10,000 per van annually.
• Increased maintenance costs would be AU$2,000 per year.
• The potential for increased sales and tax benefits are harder to quantify but should be factored in qualitatively.

Considering a 5-year timeframe:

• Total upfront cost: AU$82,000
• Total potential fuel cost savings: AU$50,000 (AU$10,000 x 2 vans x 5 years)
• Increased maintenance costs: AU$10,000 (AU$2,000 x 2 vans x 5 years)

Based on these simplified figures, there appears to be a net financial benefit after year 3. However, the  decision should also consider the intangible benefits and potential for increased sales.

Conclusion:

Upgrading the delivery vans appears to be a financially sound decision in the long term.  The cost-benefit analysis provides a framework, but the bakery owner should also consider:

• The impact of potential increased sales on profitability.
• The value of the improved brand image and employee satisfaction.
• The availability of government incentives for environmentally friendly vehicles.

By incorporating these factors, Le Pain Doré can make a well-informed decision about upgrading their delivery fleet.
