This free automation ROI calculator estimates whether automating a repetitive task is worth the cost. Enter how many tasks you handle each month, how long each takes by hand, how much of that time automation will realistically save, what an hour of your time is worth, the monthly tool cost and the one-time setup hours. It returns the hours saved, the value of that time, your net monthly gain, the payback period and the first-year return. Everything runs in your browser.
Result
- Hours saved per month
- Value of time saved
- Net monthly gain after tool cost
- Setup time as a cost
- Setup pays back in
- First-year return
How to read this result
Hours saved are tasks multiplied by minutes per task and by the share of time you expect to save. First-year return compares twelve months of value with twelve months of tool cost plus the setup time. Treat the hours as an estimate: time ten real tasks before you trust it, and remember that saved hours only become money if you spend them on paid or valuable work.

How the automation ROI calculator works
- Hours saved per month = tasks × minutes per task ÷ 60 × share of time saved.
- Value of time saved = hours saved × your hourly value.
- Net monthly gain = value of time saved − monthly tool cost.
- Setup cost = setup hours × your hourly value.
- Payback in months = setup cost ÷ net monthly gain.
- First-year return = (12 × value of time saved − (12 × tool cost + setup cost)) ÷ (12 × tool cost + setup cost).
Worked example
With the starting values (120 tasks a month, 5 minutes each, 60% of the time saved, $20 an hour, a $25 monthly tool cost and 8 setup hours), the automation saves 6 hours a month, worth $120. After the $25 tool cost the net gain is $95 a month. Setup time costs $160, so it pays back in about 1.7 months. Over the first year the value is $1,440 against $460 of cost ($300 of tool fees plus $160 of setup), a return of about 213%.
How to keep the estimate honest
- Time real tasks. Time ten tasks by hand and average them before you type the minutes in.
- Be cautious with the share saved. Reviewing and fixing the output still takes time, so a figure well below 100% is more realistic.
- Count ongoing upkeep. If the automation needs regular fixing, add that cost to the monthly tool cost.
- Value the hours truthfully. Saved time only becomes money if you spend it on paid or valuable work.
Frequently asked questions
What hourly value should I use?
Use what an hour of the saved time is worth to you: your billing rate, the wage of the person doing the task, or the value of the work you would do instead. If the hours would otherwise go unused, a lower number is more honest.
What does “not paid back” mean?
It means that at these inputs the tool costs as much as, or more than, the time it saves each month. Try a higher task volume, a lower tool cost or a more realistic share of time saved.
Does the calculator include the cost of mistakes?
No. If an error would be costly, add a human review step and lower the share of time saved to reflect it.
Is my data stored?
No. The calculation happens in your browser. If you use Copy shareable link, your inputs are placed in the web address you copy, so only share it with people who may see those numbers.
