The short answer
AI ROI = (hours saved per week x hourly rate x 4.33 weeks, minus the tool's monthly cost) divided by that cost, x 100. Most small businesses recover an AI subscription's cost within days once a workflow saves 2+ hours a week — use the calculator below with your own numbers instead of a generic industry average.
Key Takeaways
- →The formula is just three numbers: hours saved, hourly rate, and subscription cost.
- →Industry-average ROI stats are close to meaningless for a solo founder — your numbers are what matter.
- →Most AI subscriptions ($20–100/mo) pay for themselves within days once a workflow saves 2+ hours a week.
- →A low or negative ROI usually means the tool isn't in a real weekly workflow yet — not that AI doesn't work.

Why a generic ROI average won't tell you anything
Search for "AI ROI for small business" and you'll find wildly different numbers depending on who's reporting them — vendor case studies lean optimistic, independent research (McKinsey, PwC, and academic sources like NBER) tends to be far more cautious, and none of it accounts for your actual hourly rate, your actual workflow, or what you're actually paying.
Return on investment (ROI) is simple arithmetic once you plug in real numbers instead of an industry average. The calculator below does exactly that — no signup, no email required, just your three inputs and an honest answer.

How to read your result
A payback period under a week and ROI in the hundreds of percent isn't a fluke — it's what happens when a $20-100/month tool replaces even a few hours of manual work at any reasonable hourly rate. That's the actual shape of AI ROI for a solo founder or small team: the cost base is small, so the breakeven point is fast.
If your number comes out low or negative, it almost always means one of two things: the hours-saved estimate is optimistic (be honest — are you actually saving that time, or just moving it around?), or the tool hasn't made it into a real weekly workflow yet. See the small business owner's guide to running your business with AI for how to pick one workflow and stick with it for 14 days before judging the result.
