Time Card Calculator

Published on Updated on

Enter your clock-in and clock-out times for each day and get your true weekly total: regular, overtime, and double-time hours, plus gross pay at your hourly rate. This time card calculator handles overnight shifts, daily and weekly overtime rules, employer time-rounding policies, and a two-week mode for biweekly payrolls.

Weekly hours, breaks, overtime and gross pay

Biweekly: add a second week ?Opens a second week table. The weekly overtime threshold applies to each week separately, as most biweekly payrolls do.
Daily overtime after hrs/day ?Some states (for example California) require overtime after 8 hours in a single day, regardless of the weekly total.
Double time after hrs/day ?Double time comes off the top of each shift first, then daily overtime, then regular hours.

Week 1

DayClock in ?When the shift started, in 24-hour format.Clock out ?When the shift ended. A clock-out earlier than clock-in counts as an overnight shift into the next day.Break (min) ?Unpaid break minutes subtracted from the shift. Paid breaks count as work time and should be 0 here.

Quick Answer

The short answer: a week of Monday to Friday, 9:00 AM to 5:00 PM with a 30-minute unpaid break, totals 37.50 hours, all regular, and gross pay of $750.00 at $20 an hour. Add a Saturday 9:00 to 5:00 with the same break and the week reaches 45.00 hours: 40 regular plus 5 overtime at 1.5x, for a gross of $950.00. Enter the same numbers in the calculator above to reproduce this exactly.

How the calculator totals your week

Each day is computed as clock-out minus clock-in minus unpaid break minutes, converted to decimal hours. Double time comes off the top of a shift first, then daily overtime, then regular hours, and finally any regular hours above the weekly threshold are reclassified as weekly overtime. Enter your hourly rate and each bucket is priced at your regular, overtime, and double-time multipliers.

Three honest mechanics to know about. First, the rounding rule rounds each endpoint (clock-in and clock-out separately), not the shift length: with 15-minute rounding, 9:07 becomes 9:00 and 5:08 PM becomes 5:15 PM. Second, clocking out at exactly the same time you clocked in is read as a 24-hour shift, so a day with identical in and out times scores 24 hours. Third, if you set both daily overtime and double time but your double-time threshold is at or below the overtime threshold, the tool corrects it to four hours above the overtime threshold rather than producing an impossible split.

Rounding rules

Many employers round clock times under policies shaped by the federal "7-minute rule" tradition: 1 to 7 minutes past the quarter hour round down, 8 to 14 round up. The calculator offers Exact, nearest 15 minutes, nearest 30 minutes, or nearest hour, so your estimate can mirror the policy on your pay stub. Federal rules allow rounding only when it does not consistently favor the employer over time.

Watch the effect on one shift to see why the choice matters. Take a 9:31 AM clock-in and a 5:29 PM clock-out with a 30-minute break:

Rounding ruleCounted shiftDecimal hours
Exact9:31 AM to 5:29 PM, minus 30 min7.47
Nearest 15 minutes9:30 AM to 5:30 PM, minus 30 min7.50
Nearest 30 minutes9:30 AM to 5:30 PM, minus 30 min7.50
Nearest hour10:00 AM to 5:00 PM, minus 30 min6.50

The same real shift pays anywhere from 6.50 to 7.50 hours depending on the policy. Over five identical days that gap is five hours of pay, which is why picking the right rule is the single most important setting on this page.

Overtime, daily and weekly

Under the US Fair Labor Standards Act, non-exempt employees earn overtime at 1.5 times the regular rate for hours over 40 in a fixed 7-day workweek, which is the tool's default. Turn on daily overtime if your state works that way: California, for instance, requires overtime after 8 hours in a day and double time after 12, even in a week under 40 hours. The weekly overtime threshold is still applied on top, and both multipliers are editable if your contract beats the legal minimums.

A quick check you can run: one 14-hour day at $25 an hour with daily overtime after 8 and double time after 12 gives 8 regular, 4 overtime, and 2 double-time hours, for $200.00 + $150.00 + $100.00 = $450.00. The math is 8 × 25 + 4 × 25 × 1.5 + 2 × 25 × 2.

Biweekly pay periods

Check "Biweekly: add a second week" and a second time table opens. The calculator totals each week separately and applies the overtime threshold to each week on its own, which matches how most biweekly payrolls actually compute overtime. The two weeks merge into one summary table you can copy or share. The "Copy Monday to Tue-Fri" button duplicates Monday's in, out, and break values across the workweek, so a repeating schedule takes one click to fill.

Worked example

  1. Monday through Friday: clock in 9:00 AM, clock out 5:00 PM, 30-minute unpaid break. Hourly rate $20, weekly overtime threshold 40.
  2. Each day: 8 hours minus 0.5 hours = 7.50 hours. Five days give 37.50 total hours, all regular.
  3. Gross pay: 37.50 × $20 = $750.00. No overtime is due because the week stays under 40.
  4. Add Saturday 9:00 AM to 5:00 PM with a 30-minute break: the week hits 45.00 hours. The 5 hours above 40 reclassify as overtime at 1.5x: 40 × $20 + 5 × $20 × 1.5 = $950.00.

These exact numbers are pre-filled in the calculator above: press Calculate to see the same 37.50 hours and $750.00.

What competing calculators miss

Most free time card tools give you one week, one fixed overtime rule (40 hours, 1.5x), and no rounding control, so anyone with state daily-overtime rules, a 30-minute rounding policy, or a biweekly schedule ends up doing the real math by hand. The common upgrade gaps are selectable rounding granularity (rivals hardcode 15 minutes or skip rounding entirely), a two-week biweekly mode with per-week overtime (nobody else offers this), and a copy-down button for repetitive shifts. This tool also prices double time with its own multiplier instead of treating anything over 12 hours as ordinary overtime, and it shows every day's regular/overtime/double-time split in the results table so you can audit the buckets, not just the total.

Note the angle this page takes versus our time length calculator: that page does pure duration math (adding and subtracting lengths of time), while this page does pay math (turning clock times into hours and a paycheck). If you just need minutes converted to decimal hours for payroll entry, the minutes to hours converter is faster, and clock times written in 24-hour format are explained by the military clock calculator.

Time card FAQs

Add each day's clock-out minus clock-in minus unpaid break minutes, then convert the minute total to decimal hours by dividing by 60. This calculator does it per day, applies your employer's rounding rule first, and splits regular, overtime, and double-time hours automatically.
It is the common employer policy of rounding clock times to the nearest 15 minutes: 1 to 7 minutes past the quarter hour round down, 8 to 14 round up. Federal rules permit rounding only when it averages out fairly over time instead of consistently favoring the employer. Choose "Nearest 15 minutes" above to mirror this policy.
Usually yes. The Fair Labor Standards Act defines the workweek as a fixed recurring 7-day period, so weekly overtime is computed per week even when paychecks arrive biweekly. This tool applies the overtime threshold to each week separately in biweekly mode.
If clock-out is earlier than clock-in, the tool treats the shift as running into the next day by adding 24 hours. A 10:00 PM to 6:00 AM shift with no break counts as 8 hours. Note that clocking in and out at exactly the same time is read as a full 24-hour shift.
Short rest breaks of about 20 minutes or less are generally paid and count as work time, so they should not go in the Break column. Meal breaks of 30 minutes or more are generally unpaid when you are fully relieved of duty, and those are the minutes to enter.
That combination is impossible (double time must kick in after overtime), so the tool corrects it: when both options are on and the double-time threshold is at or below the daily overtime threshold, the double-time threshold is raised to four hours above the overtime threshold before the math runs.
Because the rule rounds each clock-in and clock-out time separately before the shift length is computed, so two endpoints can each move up to half the rounding unit. A 9:31 AM in and 5:29 PM out under nearest-hour rounding become 10:00 AM and 5:00 PM, a full hour difference from the exact times.
No. Gross pay is earnings before federal and state taxes, Social Security, Medicare, and any deductions. It is the right number for checking that your hours and overtime buckets are correct, but your paycheck will be lower after withholdings.
