AI Agent ROI Calculator
How do you calculate the ROI of an AI agent?
Work out the human time the agent removes (tasks handled × minutes saved, after the review time a person still spends), value it at the loaded hourly cost, then subtract the running cost per task, yearly maintenance and the one-off build cost. This calculator shows the result for three shares of tasks the agent handles end to end — 30%, 50% and 70% — so you can see the range rather than one optimistic number.
Your process
How many times the process runs each month.
Hands-on time today, excluding waiting.
Salary plus overheads, per hour.
Share of tasks that have to be redone today.
Time a person still spends checking the agent.
Model, hosting and tool calls. Use the token cost calculator.
Replace the example with your own quote.
Monitoring, fixes and model updates.
Your expected case. A pilot is the only reliable way to measure it.
Frequently asked questions
Where do the default numbers come from?
They are editable examples, not benchmarks. Replace them with your own volumes, costs and a real build quote; every figure in the result comes from the inputs on the page.
What share of tasks can an AI agent handle?
It depends on how varied the task is and how much judgement it needs. That is why the calculator shows 30%, 50% and 70% side by side. A pilot on your own data is the only reliable way to measure it.
What costs are not included?
Change management, staff training, software licences and integration work you have not counted in the build cost. Add them to the build cost for a fuller picture.
