How to calculate automation ROI
Automation ROI compares the time a repetitive task costs your team with what it costs to automate it. The calculator uses four simple steps:
- Time spent: minutes per run × runs per week × people doing the task.
- Time saved: time spent × the share of the task the automation handles, converted to hours.
- Money saved: hours saved per year × the hourly cost of the people doing it.
- Return: (money saved − automation costs) ÷ automation costs, over three years.
The payback period is how long the net weekly saving takes to cover the one-time cost of building the automation. Running costs such as hosting, API usage and maintenance are subtracted first, so the result reflects what you actually keep.
A worked example
A team member spends 20 minutes twice a day copying orders into a spreadsheet. Over a five-day week that is 200 minutes. If an automation handles 90% of it, it saves 3 hours a week, or 144 hours over 48 working weeks. At an hourly cost of $35, that is $5,040 a year. With a $1,500 build and $50 a month in running costs, the automation pays for itself in about four months and returns several times its cost over three years.
Which tasks give the best return?
The highest returns come from tasks that are:
- Frequent: daily or weekly work pays back far faster than a yearly task.
- Rule-based: if the steps fit on a one-page checklist, a script can follow them.
- Shared: the same task done by several people multiplies the saving.
- Error prone: manual copying causes mistakes that cost time to find and fix.
Typical examples include moving data between tools, building recurring reports, monitoring prices or stock, and processing documents. My guide on how to automate repetitive business tasks with Python and AI explains how to pick and run your first automation.
What the calculator does not include
The estimate focuses on time. Automation often brings extra value that is harder to price: fewer errors, faster turnaround for customers, work that runs overnight and staff who can focus on higher-value work. If those matter to you, the real return is usually higher than the number shown.
