How to Read a Time Card

A time card (or timesheet) records the hours an employee works during a pay period. Each day has a clock-in time (when work starts), a clock-out time (when work ends), and any unpaid break minutes that are subtracted from the total. The worked hours for a day equal the time between clock-out and clock-in, minus break time.

• Clock In / Clock Out: Use 24-hour or AM/PM times. Overnight shifts that cross midnight are handled automatically.
• Break: Enter unpaid break time in minutes (lunch, etc.). Paid breaks should be left out.
• Weekly total: The sum of every day's worked hours, used to determine regular vs. overtime hours.

Overtime Rules

In the United States, the Fair Labor Standards Act (FLSA) requires that non-exempt employees receive overtime pay of at least 1.5 times their regular rate for hours worked beyond 40 in a workweek. Some states and countries use different thresholds or daily overtime rules, so you can adjust the weekly threshold and the overtime multiplier above.

• Regular hours: All hours up to the weekly threshold (default 40).
• Overtime hours: Any hours above the threshold.
• Gross pay: regular × rate + overtime × rate × multiplier.

Decimal Hours vs. HH:MM

Payroll systems usually calculate pay using decimal hours, while time clocks often display hours and minutes. To convert minutes to a decimal, divide by 60. For example, 30 minutes is 0.5 hours and 15 minutes is 0.25 hours. This calculator shows both formats so you can verify totals against your timesheet or payroll software.

• 15 minutes = 0.25 hours
• 30 minutes = 0.50 hours
• 45 minutes = 0.75 hours
