Payroll Calculators

Payroll math has a way of punishing small mistakes: a mis-added break, a forgotten overtime threshold, hours typed as 7.30 instead of 7.50 — each one quietly moves real money. This collection exists so hourly workers, managers and small payroll teams can check the numbers in seconds, with every step of the working visible.

The time card calculator totals a full week from clock-in and clock-out times: unpaid breaks come off, overnight shifts are handled, and hours over 40 split into overtime automatically. Pair it with the overtime pay calculator, which applies time-and-a-half (or double time, or any custom multiplier your contract uses) and shows the regular-pay versus overtime-pay breakdown line by line — the exact working most pay stubs never show.

The method follows the federal Fair Labor Standards Act: overtime after 40 hours in a workweek for non-exempt employees, with paid leave counting toward pay but not toward the overtime threshold. Where state law is stricter — daily overtime, double time — the stricter rule wins, and the calculator notes where that applies.

Use these tools to verify a paycheck, settle a timesheet dispute with evidence, or sanity-check payroll before it runs. They are estimates for checking purposes, not legal advice — but an estimate with its working shown beats a pay stub with none.
