Quick answer

Time Card Calculator: what it calculates

Time Card Calculator calculates work hours from entry mode, start and end times, unpaid break minutes, days worked or daily rows, pay period, hourly rate, and 1 additional input. The visible formula is Row hours = hours between start and end - unpaid break minutes / 60; pay period hours = sum of included rows; straight-time gross pay = pay period hours x hourly rate.

Formula

Time card formula

Row hours = hours between start and end - unpaid break minutes / 60; pay period hours = sum of included rows; straight-time gross pay = pay period hours x hourly rate

An end time earlier than its start is treated as an overnight shift. The optional threshold splits hours within each week but does not add an overtime premium.

How to use

Steps

  1. Choose Simple schedule for a repeated shift or Daily rows for a day-by-day time card.
  2. Enter start, end, and unpaid break time for the shifts you worked.
  3. In Daily rows, turn off non-work days and choose a weekly or biweekly pay period.
  4. Optionally split hours above your own weekly review threshold.
  5. Add an hourly rate to estimate straight-time gross pay before deductions or any overtime premium.
  6. Copy the summary or print the calculated time card for your records.

Calculator use

Best for

  • Use the simple schedule for repeated shifts, or enter individual daily rows to total weekly or biweekly hours, unpaid breaks, and straight-time gross pay.
  • Checking calendar, work-hour, school, deadline, age, or duration math before copying the result elsewhere.
  • Comparing inclusive versus exclusive dates, breaks, grading weights, or time spans with the assumptions visible.
  • Doing a quick schedule or school planning check without opening a spreadsheet.

Before relying on it

Check first

  • Mixing inclusive and exclusive date counting, time zones, overnight shifts, unpaid breaks, holidays, or school-specific grading rules.
  • Rounding time or grades too early and then using the rounded result in another calculation.
  • Treating a planning result as payroll, HR, transcript, legal deadline, or official school policy.

Details

What to know before using the result

Break handlingUnpaid minutes subtracted

Enter only unpaid break time that should not count as hours worked. Paid breaks should stay in the shift total.

Daily rowsDifferent shifts by day

Use individual rows when start times, end times, or unpaid breaks change during the week. Turn off rows for days you did not work.

Overnight shiftsEnd before start

If the end time is earlier than the start time, the calculator treats the end time as the next calendar day.

Overtime thresholdOptional weekly split

The threshold separates regular and above-threshold hours within each week. It does not determine eligibility or apply an overtime pay multiplier.

Pay estimateStraight-time gross pay

Gross pay is before taxes, benefits, retirement contributions, overtime premiums, employer rounding, and local payroll rules.

FAQ

Common questions

Does the time card calculator subtract lunch?

Yes. Enter lunch or other unpaid break time in minutes and it is subtracted from the shift total.

Can it calculate overnight shifts?

Yes. If the end time is earlier than the start time, the calculator treats the end time as the next day.

Can I enter a different shift for each day?

Yes. Choose Daily rows to enter separate start times, end times, and unpaid breaks for each worked day.

Can I calculate a biweekly time card?

Yes. In Daily rows, choose Biweekly to enter and total two separate seven-day weeks.

Does the overtime threshold calculate overtime pay?

No. It only separates hours above your chosen weekly threshold. The gross-pay estimate uses the straight hourly rate and does not determine eligibility or add a premium.

Is gross pay the same as take-home pay?

No. Gross pay is before taxes, benefits, retirement contributions, and other deductions.
