Before you write that script or set up that workflow, check whether it will pay off. Enter how long the task takes, how often you do it and how long automation will take to see net hours saved, payback time and the most time worth spending.

How to use the Is It Worth Automating? Calculator
Enter the task: how long it takes by hand and how often you do it.
Set the horizon: how many years you'll keep doing it (5 is a common choice).
Estimate the effort to automate it, plus maintenance and any tool costs.
Calculate to see whether automation pays off, the payback time and the most time worth spending.
Use the grid to quickly size other tasks.
Automation payback formulas
Runs per year = times per period × periods per year (365 days, ~250 workdays, 52 weeks, 12 months)
Time saved = time per run × share automated × runs per year × years
Time invested = build time + maintenance per year × years
Net time = time saved − time invested
Payback = build time ÷ (time saved per year − maintenance per year)
ROI = (hours saved × hourly value − hours invested × hourly value − tool costs) ÷ total cost
Example
A 5-minute task done 4 times a workday (250 workdays) takes about 83 hours a year, or 417 hours over 5 years. Automating it in 16 hours with 4 hours of yearly maintenance costs 36 hours, so it saves about 381 hours and pays back in about 2.4 months.

Tips
Automate the boring part first; partial automation (say 70%) often captures most of the benefit.
Count the time to explain and hand over the automation to teammates.
Re-check after a month: track actual runs and time saved rather than relying on estimates.
Frequently asked questions
How do I know if a task is worth automating?
Multiply the time saved per run by how many times you'll run it over the period you care about, then compare that with the time to build and maintain the automation. If total time saved is larger, it pays off. The calculator also converts the hours to money and gives a payback time.
What is the formula?
Time saved = time per run × share automated × runs per year × years. Net time = time saved − (build time + maintenance per year × years). Max time worth spending to automate = time saved − maintenance (− tool costs ÷ hourly value).
Why use a 5-year horizon?
Five years is a popular rule of thumb because many tasks, tools and jobs change within that time. Use a shorter horizon if the process might change soon, or longer for stable, long-lived chores.
Why do my automations take longer than planned?
Building is usually the easy part; edge cases, testing, documentation and fixing it when something upstream changes take longer. Many people add 50% to 100% to their first estimate and include yearly maintenance.
Is saving time always the only benefit?
No. Automation can cut errors, make work repeatable, free you from interruptions and let tasks run at night. If those matter, a slightly negative time balance can still be worth it, which the calculator can't measure.
How is the grid table calculated?
Each cell is time saved per run × runs per year × your horizon, shown in seconds, minutes, hours, 24-hour days or months. It's the most time you could spend automating that task before you lose time overall (ignoring maintenance).
