Time Card Calculator

Enter each day's start time, end time and unpaid break in minutes. The tool computes per-day hours, the weekly total, and the split between regular hours and overtime above whatever threshold you set — 40 hours by default. Add an hourly rate and it estimates the paycheck, paying the regular hours at that rate and the overtime at one and a half times it.

Shifts that cross midnight are handled: if the end time is earlier than the start time, a full day is added before the break is subtracted, so 22:15 to 06:45 with a 30-minute break comes out as 8.0 hours rather than a negative number. The one case this cannot express is a shift of exactly 24 hours or longer, because an end equal to the start is read as a zero-length day. Split a double shift into two rows instead of trying to fold it into one.

Hours are reported in decimal, which is where paper time cards most often go wrong: 7.75 hours is seven hours and forty-five minutes, not seven hours seventy-five. If you are copying the total into a payroll form that wants hours and minutes, multiply the fractional part by 60 rather than reading it as minutes directly. The per-day figures let you catch a mistyped time before it reaches the weekly total, since a single digit wrong in one start time shifts everything downstream.

The overtime rules are the part to check against your own jurisdiction, because the tool implements the simplest version of them. United States federal law under the FLSA owes time-and-a-half on hours past 40 in a workweek and has no daily overtime at all, so twelve hours on Monday and four on Tuesday is ordinary time. Several states are stricter — California adds overtime past eight hours in a day and double time past twelve — and many countries compute from a different period entirely, or from a collective agreement. A fixed weekly threshold cannot represent any of that, and neither can a single multiplier: under the FLSA, overtime is owed on the regular rate, which folds in non-discretionary bonuses and shift differentials, so a paycheck estimate built from a bare hourly rate will read low whenever those apply. Treat the output as a check on someone else's arithmetic, not as the payroll record itself.
