How much productivity improvement can AI tools provide?

Studies suggest AI tools like large language models can improve productivity for knowledge workers by 20–40% for tasks they are well-suited for. Writing, coding, research, and data analysis tasks see the largest gains.

How do I calculate the ROI of an AI tool subscription?

Calculate the time saved per week, multiply by your hourly value, and compare to the monthly subscription cost. If you save 2 hours per week at €50/hour, that is €400/month in value against a typical €20–50/month tool cost.

What AI tools have the highest productivity impact?

AI writing assistants, code completion tools (GitHub Copilot), meeting summarization tools, and research assistants typically show the highest productivity impact. Choose tools that match your most time-consuming tasks.

The AI productivity calculator estimates how much time and money you save by using AI tools and computes their return on investment. Enter the time a task takes and the tool's cost to see whether the investment pays off.

How the calculator works and what it’s for▾

How time savings and ROI are calculated

The calculator compares how long a task used to take with how long it takes with AI. The difference is the time saved, which is converted into money through an hourly rate or the value of the work.

Return on investment is found by relating the gained benefit to the tool's cost. If the saving exceeds the cost, the investment is worthwhile.

What you enter and what you get

You typically provide the time a task takes before and after, the value of the work and the price of the tool. In return you get the hours saved, the monetary benefit and the ROI percentage.

These figures make it easy to justify whether a tool is worth acquiring or keeping.

Who it is for

The tool serves entrepreneurs, team leads and specialists who are considering adopting AI tools or want to measure the benefit of ones already in use.

It helps base purchasing decisions on numbers rather than gut feeling.

Good to know

The result is an estimate that depends on the accuracy of the figures you enter. Factor in the learning curve of adoption and any changes in quality for the full picture.

Update the estimate once you have real experience of using the tool.
