A simple way to estimate AI ROI in your business

Matt Harris · October 13, 2026 · 3 min read

You don't need a complex model to know whether AI is worth it. Four numbers get you most of the way there.

Before investing in AI, most owners want a straight answer: will this pay for itself? A useful first estimate needs only a few numbers.

  • Hours the task takes each week
  • How much of that time AI can reduce
  • How much of the team will actually use it
  • Hours of human review it adds
  • Loaded cost per hour and monthly running costs

A worked example

Take a 20-hour-a-week task at $40 an hour. With a 50% time reduction and 80% adoption, it frees 8 hours. Added review takes 3 hours back, leaving 5 net hours, or $10,400 a year. Subtract $2,400 in running costs and the workflow nets $8,000 a year.

Be conservative

Use the low end of your time-savings estimate, and count only the tasks you are confident AI can handle with human review. Treat freed time as capacity, not cash, unless it removes overtime, a planned hire, or outside spend. If the conservative number still works, you have a strong case.

In the AI Strategy Blueprint we build this model for your top five use cases with your real numbers.
