Use hours, loaded rate, headcount, schedule, and system cost to estimate labor value, net annual impact, and payback. The result is a planning estimate, not a promise.

After subtracting the system’s annual running cost.
The same inputs, broken out the way a budget conversation actually goes.
Gross labor value recovered each working week.
Gross savings averaged across the year.
Before the system’s running cost comes out.
Net annual × your horizon. No discounting applied.
System cost divided by gross annual savings, in months.
Hours your team gets back for work that doesn’t need a human staring at a spreadsheet.
Every number this tool shows, and where it comes from.
Formula. annual savings = hours × rate × people × weeks. Net annual subtracts your all-in system cost. Payback is system cost divided by gross annual savings, expressed in months.
Fully-loaded hourly cost. Use total compensation (salary + benefits + payroll tax + share of overhead), divided by roughly 2,000 hours per year. For US knowledge workers, the loaded multiplier is typically 1.25–1.4× base salary. Reference: BLS Employer Costs for Employee Compensation.
No discounting. Multi-year totals are simple sums. If you want NPV, apply your own discount rate (commonly 8–15% for internal projects).
What it doesn’t model. Quality gains, error-rate reduction, opportunity cost of slow workflows, or revenue lift from faster execution. These often dwarf labor savings; treat the number here as a conservative floor.
