Time Card Calculator

How to use the time card calculator

Enter the clock-in time, clock-out time, and break minutes for each day actually worked. The calculator carries an out time at or before the in time into the following day, so a night shift does not become a negative duration. It then returns each day in hours and minutes, each day as a decimal, and the workweek total.

The loaded card has four 8-hour days and one 9-hour day after five 30-minute meals. The engine totals 41.00 hours, assigns 40.00 to the regular bucket, and assigns 1.00 to federal overtime. At the loaded $22.00 hourly wage, that is $880.00 regular pay, $33.00 overtime pay, and $913.00 estimated gross pay before deductions.

Keep the page to one workweek even when the pay stub covers two. A workweek is the employer’s fixed, recurring 168-hour period and may begin on any day and at any hour. If a biweekly card contains 45 hours followed by 35, the engine returns 5 overtime hours for the first week and none for the second; averaging both to 40 is not permitted federally.

Choose the overtime preset only after identifying both the workweek and, where state law uses one, the workday. California defines a workday as the employer’s recurring 24-hour period, which need not start at midnight or match a shift. The calculator groups the entered row as a day, so an overnight shift split by the employer’s workday boundary needs a manual check.

1. 1

   Exact minutes preserve the punches

   Use this mode when the timekeeping system captures actual minutes and no valid rounding policy applies.

2. 2

   Nearest 5, 6, or 15 minutes changes credited time

   The engine rounds to the nearest mark and reports whether the workweek gained or lost minutes.

3. 3

   The long-run result determines federal compliance

   A single favorable or unfavorable week does not establish whether a rounding practice compensates all time over time.

Rounding is optional, not a license to shave time. Section 785.48(b) names the nearest 5 minutes, one-tenth of an hour, or quarter hour and accepts the practice only when it does not underpay over time. The regulation never says “7-minute rule”; that phrase merely describes neutral nearest-quarter rounding, where minutes 1 through 7 round back and 8 through 14 round forward.

Why the calculator stops after one workweek

Federal overtime is a weekly test. The workweek is a fixed sequence of seven consecutive 24-hour periods, and it does not have to align with Monday, the calendar week, or the payroll cycle. Once established, its beginning stays fixed unless a genuine permanent change is made rather than a change designed to avoid overtime.

That boundary makes a biweekly total misleading. A worker with 45 hours in week one and 35 in week two has 80 hours across the check, yet the engine finds 5 overtime hours by testing the weeks separately. The second week cannot erase the premium earned in the first, even though the combined average is exactly 40.

Federal law has no general daily-overtime trigger, so a 12-hour Monday inside a 35-hour federal workweek produces no overtime by itself. State law can be more protective. The reference table identifies the broad daily presets available in the engine and states the condition the threshold alone cannot express.

Break deductions and rounding need separate checks

Break length and break conditions answer different questions. A 15-minute rest is paid work under the federal rule. A 30-minute meal can be unpaid only when it is bona fide and the employee is completely relieved from duty; answering calls, watching equipment, or remaining responsible for work prevents that federal exclusion even if no task arrives.

Rounding asks whether recorded punches may move to nearby increments. The federal regulation permits specified nearest-mark practices only when they do not, over time, fail to compensate all work. The engine therefore shows weekly drift without pronouncing the policy lawful. One card is evidence of an arithmetic result, not evidence of the long-run pattern the regulation requires.

California adds an unresolved layer to ordinary work-time rounding. Camp v. Home Depot is a 2022 Court of Appeal decision under California Supreme Court review as of August 2026, so the review-granted opinion has no binding effect under Rule 8.1115(e). Donohue barred rounding meal-period punches in 2021 but did not decide work-time rounding generally.

That uncertainty is a reason to preserve exact punches and check current state guidance, not a reason to assume either that every neutral policy is valid or that every rounded punch creates liability. The governing facts include what the system captured, how the policy operated over time, which state applies, and whether the interval was work, rest, or a duty-free meal.

The formula, worked line by line

Each worked day begins as clock minutes. The engine moves an end time at or before the start into the next day, subtracts the entered break without allowing a negative day, and then applies the selected nearest-mark rule. Decimal hours appear only after the calculation, so 7 hours 29 minutes remains 449 minutes until the final display.

Daily premiums are assigned before the weekly threshold in state presets. Only minutes still in the regular bucket face the weekly test, which prevents the same hour from being counted twice. Under the federal preset there is no daily stage, so the first 40 weekly hours remain regular and every remaining minute enters the time-and-a-half bucket.

Pay is calculated in integer cents. Regular minutes use the entered hourly wage, overtime minutes use the selected 3-to-2 multiplier, and California double-time minutes use 2-to-1. This time-card page estimates gross pay from the stated wage; it does not build the broader regular rate that can include bonuses and differentials.

gross day minutes = out − in, adding 1,440 when the shift crosses midnight
raw day minutes = max(0, gross day minutes − entered break minutes)
credited day minutes = nearest selected 1, 5, 6, or 15-minute mark
weekly overtime minutes = max(0, remaining regular minutes − 2,400)
gross pay = regular pay + 1.5× overtime pay + 2× double-time pay

The diagram uses a different five-shift card so the crossing is visible: 9.50, 8.00, 8.00, 8.00, and 9.00 hours. The engine totals 42.50, leaving 40.00 regular and 2.50 overtime under the federal preset. The longest day does not create federal overtime; the workweek crossing 40 does.

Treat the output as an estimate and not legal advice. A classification exemption can remove the federal overtime requirement, while a state rule, industry order, union agreement, alternative workweek, prevailing-wage term, or employer policy can add protection. When the calculated card and the pay record differ materially, preserve the original punches and obtain advice for the specific jurisdiction.
