What counts and what doesn't
For credible ROI, only count cash-out-of-the-business saved (or genuinely deferred). Don't count 'time freed for higher-value work' unless you can prove the higher-value work happened and produced revenue.

What is the ROI of AI agents?
Direct answer
AI agents in UK SMEs typically deliver a 2–4× return on investment in year one and 5–10× from year two onward, with payback in 60–120 days. ROI is calculated as (annual labour replaced) ÷ (build + annual run cost). Repetitive admin and support functions deliver the highest ROI.
Definition
AI agent ROI: Return on investment from deploying an AI agent, calculated as annual labour cost replaced divided by total AI cost (build + run), expressed as a multiple or percentage.

What's a bad AI ROI?+
Anything under 1.5× year-1 means the use case is wrong, the build is overscoped, or adoption failed. Pull the plug and re-scope.
How do you measure it?+
Pre/post hours per task × people doing them × hourly rate. We track this in dashboards from day one of every Creative Agent build.
