Understanding AI Automation ROI

When considering AI automation for your Australian business, the question isn't whether you can afford it—it's whether you can afford NOT to automate.

In this comprehensive guide, we'll show you exactly how to calculate your return on investment for AI automation projects, with real examples from Sydney and Melbourne businesses we've worked with.

The Simple ROI Formula

Calculating ROI on automation is straightforward:

ROI = (Time Saved × Hourly Rate) - Automation Cost

Example: Sydney Real Estate Agency

A Sydney real estate agency was spending 15 hours per week manually responding to property inquiries and booking viewings.

  • Time spent: 15 hours/week
  • Staff hourly rate: $40/hour
  • Weekly cost: $600
  • Annual cost: $31,200

Solution: We implemented an AI voice assistant that handles inquiries and books viewings 24/7.

  • Automation cost: $4,500 (one-time setup)
  • Ongoing costs: $150/month ($1,800/year)
  • Time saved: 12 hours/week (80% of manual work)
  • Annual savings: $24,960

First Year ROI: $24,960 - $6,300 = $18,660 profit

ROI Percentage: 296% return in Year 1

Payback period: 2.5 months

What Costs to Include

One-Time Costs:

  • Initial setup and development
  • Integration with existing systems
  • Training and documentation
  • Testing and optimization

Ongoing Costs:

  • AI platform fees (OpenAI, Claude, voice AI services)
  • Hosting and infrastructure
  • Monthly support and maintenance (optional)
  • API costs based on usage

Hidden Benefits Beyond Time Savings

While time savings are easy to calculate, don't forget these additional benefits:

  • 24/7 availability: Capture leads outside business hours
  • Consistency: Every customer gets the same quality experience
  • Scalability: Handle 10x more inquiries without hiring
  • Data insights: Track every interaction for better decisions
  • Staff satisfaction: Team focuses on high-value work, not admin

Free ROI Calculator

Want to calculate your specific ROI? Use our simple calculator:

  1. Estimate hours spent on repetitive tasks per week
  2. Multiply by your average hourly cost (salary ÷ 2080 hours/year)
  3. Multiply by 52 weeks to get annual cost
  4. Subtract estimated automation cost
  5. That's your potential annual savings!

When ROI Doesn't Make Sense

We're honest: Not every task should be automated. Skip automation if:

  • Task requires complex human judgment
  • Task happens less than 2 hours per week
  • Process changes frequently (automation becomes outdated)
  • Staff genuinely enjoy the task (improves morale)

Real Australian Business Examples
