Decide on Automation with Numbers, Not Gut Feel
"Should we automate this test?" is a question most teams answer by instinct. But automation comes with a real setup cost — writing scripts, configuring environments, learning maintenance — and the time it takes to pay that cost back can actually be calculated. The more often a test runs, and the bigger the time gap between manual and automated execution, the faster it pays off.
This calculator takes manual test time per run, weekly run count, automation setup time, automated time per run, and hourly labor cost, then calculates your break-even point (in weeks) and annual net savings. For example, automating a 30-minute test that runs 10 times a week down to 5 minutes pays back a 40-hour setup investment within a few weeks — and turns into pure savings after that.
On the flip side, tests that rarely run, or that don't get much faster after automation, can have a very long payback period. In those cases, removing or consolidating the test may be a better move than automating it. Remember that automation is a means, not a goal — prioritize tests that run often and save significant time over manual execution.
FAQ
Not necessarily — it just means lower priority. Automate the more frequently run tests first for better efficiency.
This calculator only reflects the initial setup cost. In practice, you should also factor in ongoing maintenance of automation scripts.
No. Tests that run infrequently or have frequently changing UI often have low automation ROI, so apply it selectively.
