The useful question is how much work your actual automation avoids after residual handling and maintenance. This calculator keeps hours, the value you assign to those hours and software cash cost visible as separate quantities. It does not convert every saved minute into payroll savings or revenue.
INPUT → RULES → LOCAL RESULT
Automation time-value scenario
Compare measured manual and residual work, then keep time value separate from software cash cost. Use one currency across the monetary fields.
100 runs with five minutes avoided per run gives 8.3333 hours before monthly maintenance.
Enter the scenario to see a result.

Measure the same workflow on both sides
Count comparable runs over a stated month. Measure manual minutes per run and the work that remains after automation, including routine checking and exception handling. Subtract extra monthly maintenance hours separately. Do not count the same exception work in both residual minutes and maintenance.
Net hours avoided are (manual minutes − residual minutes) × monthly runs ÷ 60 − maintenance hours. With 100 runs, five manual minutes and zero residual minutes, the example gives 8.3333 hours before maintenance. A workflow taking longer after automation correctly produces a negative result rather than a savings claim.
Keep time value separate from cash
Multiplying net hours by your chosen hourly value creates a time-value scenario. Software cash cost is then shown alongside it and subtracted to produce a modeled difference. Use one currency for hourly value, software and one-time setup cost. A zero hourly value is valid if you want to examine time without assigning money.
An employee who stays on the same salary may use released time for other work without reducing payroll. A founder may value reclaimed time without selling another hour or gaining a customer. The calculator cannot establish either outcome. No productivity percentage, wage, subscription price or revenue uplift is supplied as a fact.
Treat setup recovery as a scenario
When the monthly modeled difference is positive, one-time setup cost divided by that difference gives modeled recovery months. This is not an investment return or a cash-flow forecast: it assumes the same workload, measured effort, time value and software cost continue. At zero or negative monthly difference, there is no recovery duration to calculate.
Record the source and observation period of each input. If exception rates, volumes or software tiers vary, compare separate runs of the worksheet rather than hiding the variation in one optimistic number. Browser print can keep your stated assumptions with the output.
Check the usage bill separately
An integration’s task, credit and execution units are not interchangeable. The billing-unit worksheet models those quantities, while its linked current vendor documentation identifies billing scope.

Method and sources
The time and cost relationships are original arithmetic from reader measurements, not a deployed automation test. Current billing definitions were reviewed October 15, 2026 through Zapier task usage, Make credits and n8n execution pricing. Those sources do not establish your time savings or economic outcome.
