Time Card Calculator Guide

How to Calculate Time Card Hours

To calculate hours worked: subtract your start time from your end time, then subtract any break time. For example: Start 9:00 AM, End 5:00 PM, 30-minute lunch = 8 hours - 0.5 hours = 7.5 hours worked. Our calculator handles this automatically for each day.

Overtime Rules

Under the Fair Labor Standards Act (FLSA), non-exempt employees must receive overtime pay of 1.5x their regular rate for all hours worked over 40 in a workweek. Some states have daily overtime rules (e.g., California requires overtime after 8 hours in a day). This calculator uses the federal 40-hour weekly threshold.

Handling Lunch Breaks

Enter your break duration in the "Break" column. Common break deductions:

Paid breaks should NOT be subtracted. Only enter unpaid break time.

Overnight and Split Shifts

This calculator handles overnight shifts automatically. If your end time is earlier than your start time (e.g., start 10:00 PM, end 6:00 AM), the calculator assumes the shift crosses midnight and calculates correctly (8 hours in this example).
