Calculator options
Overtime is counted per workweek (7-day blocks from your start date), as the FLSA requires. Workweek 2 in a biweekly sheet has its own 40-hour threshold. Leave daily OT/DT blank for the standard federal rule; check California for the §510 daily rules.
From punch clock to paycheck
A time clock records raw punches; payroll needs worked hours. This calculator does the conversion chain in one place: subtract unpaid breaks, handle overnight shifts, apply rounding if your employer rounds (see the options), convert to decimal hours, and split regular vs overtime hours per workweek.
Rounding, done honestly
Under the 7-minute rule, punches round to the nearest quarter hour: minutes :00–:07 round down, :08–:22 to :15, :23–:37 to :30, :38–:52 to :45, :53+ to the next hour. Rounding must not systematically favor the employer — see our time card rounding guide for how the rules work.
