Time Card Calculator

How to Use the Time Card Calculator

The Time Card Calculator is an essential tool for tracking work hours, calculating overtime, and generating detailed time card reports. It's designed to be user-friendly and efficient for both employees and managers.

Formulas and Components

The calculator uses the following key formulas:

1. Total Hours (TH): \[TH = \sum_{i=1}^{n} (End Time_i - Start Time_i)\]
2. Regular Hours (RH): \[RH = \min(TH, OT)\]
3. Overtime Hours (OH): \[OH = \max(0, TH - OT)\]

Where:

• n = number of work days
• End Time_i and Start Time_i = daily work end and start times
• OT = Overtime Threshold (typically 40 hours per week)

Calculation Steps

1. Input the number of work days for the period.
2. Enter start and end times for each workday.
3. Set the overtime threshold (default is 40 hours).
4. Click "Calculate" to process the data.
5. The calculator will:
   • Compute daily work hours
   • Sum up total hours
   • Determine regular hours
   • Calculate overtime hours
   • Generate a comprehensive time card report

Example Calculation

Let's calculate a time card for a 5-day work week:

1. Work Days: 5
2. Daily Schedule:
   • Monday: 9:00 AM to 5:30 PM
   • Tuesday: 8:30 AM to 6:00 PM
   • Wednesday: 9:00 AM to 5:00 PM
   • Thursday: 8:45 AM to 5:45 PM
   • Friday: 9:00 AM to 6:30 PM
3. Overtime Threshold: 40 hours

Calculation:

1. Daily Hours:
   • Monday: 8.5 hours
   • Tuesday: 9.5 hours
   • Wednesday: 8 hours
   • Thursday: 9 hours
   • Friday: 9.5 hours
2. Total Hours: 8.5 + 9.5 + 8 + 9 + 9.5 = 44.5 hours
3. Regular Hours: min(44.5, 40) = 40 hours
4. Overtime Hours: max(0, 44.5 - 40) = 4.5 hours
