Calculating Overtime with Clock In Clock Out
Understanding Overtime Rules
Standard overtime calculation (US):
- Regular time: First 40 hours per week
- Overtime rate: 1.5× regular hourly rate
- Double time: Some states require 2× for hours over 12/day
Overtime Example
Weekly Hours:
- Monday-Friday: 9 hours/day = 45 hours
- Overtime hours: 5 hours
- Regular pay: 40 hours × $20 = $800
- Overtime pay: 5 hours × $30 = $150
- Total weekly pay: $950
Daily vs. Weekly Overtime
Different jurisdictions have different rules:
California (Daily):
- Over 8 hours/day = 1.5× pay
- Over 12 hours/day = 2× pay
- 7th consecutive day = 1.5× or 2× pay
Federal (Weekly):
- Over 40 hours/week = 1.5× pay
Always check your local labor laws!
