Time card calculator

Total a seven-day time card into weekly regular and overtime hours.

What this calculator covers

Use this calculator for weekly timesheet math when you want regular and overtime hours separated instead of only seeing one weekly total.

Because each day stays independent before the week is summed, the result remains easier to audit when some days are blank, longer than usual, or overnight.

Frequently asked questions

How does the calculator handle break time?
Each day has its own break-minutes field. Those minutes are subtracted from the raw clock span before the day's net hours are added to the weekly total, so unpaid breaks do not inflate your regular or overtime counts.
What counts as an overnight shift?
If a shift's end time is earlier than its start time — for example, starting at 22:00 and ending at 06:00 — the calculator automatically treats the end time as belonging to the next calendar day and adds the correct number of hours.
Can I change the overtime threshold?
Yes. The weekly overtime threshold defaults to 40 hours but can be adjusted. Any net weekly hours above that threshold are counted as overtime; everything up to the threshold is counted as regular time.
What happens if I leave a day blank?
A day row is ignored when both the start and end times are blank and the break field is zero. Partially filled rows may produce an error, so either complete the row or clear it entirely.

Step-by-step solution

  1. 1.Validate each completed day as a start time, end time, and break deduction, allowing overnight rows when the end time is earlier than the start time.
  2. 2.Sum the net day totals to reach 38.00 hours after subtracting 180 break minutes.
  3. 3.Cap regular time at 40 hours and classify the remaining 0.00 hours as overtime.

Walkthrough

Visual walkthrough

Time-card math has two layers: total the week's worked time, then split that total at the overtime threshold.

  1. 01

    Add the worked days

    5 days

    Blank days are ignored, while completed days contribute net minutes after their break deductions.

  2. 02

    Read the weekly total

    38.00 hours

    The week total comes from net worked minutes, not raw clock span before unpaid breaks.

  3. 03

    Split regular and overtime

    38.00 regular + 0.00 overtime

    Regular time is capped at 40 hours for the week.

    38.00 regular + 0.00 overtime
