About Time Card Calculator
The Time Card Calculator helps employees and employers accurately track work hours, calculate overtime, and estimate pay. Whether you're managing your own hours or calculating payroll, this tool simplifies time tracking.
How Work Hours Are Calculated
Basic Formula
Total Hours = Clock Out Time - Clock In Time - Break Duration
Overtime Calculation (US Standard)
- Regular Hours: First 40 hours per week at regular rate
- Overtime Hours: Hours exceeding 40 per week at 1.5× rate (Time and a Half)
- Double Time: Some states/jobs use 2× rate for hours over 12/day or 60/week
Example Calculation
Clock in: 9:00 AM, Clock out: 5:30 PM, 30-min lunch break:
- Total time: 8.5 hours
- Less break: 8.5 - 0.5 = 8 hours worked
- Pay at $20/hour: 8 × $20 = $160
Understanding Overtime Pay
Federal Overtime Laws (FLSA)
The Fair Labor Standards Act requires:
- 1.5× pay for hours worked over 40 per week for non-exempt employees
- No federal requirement for daily overtime
State-Specific Rules
| State | Daily Overtime | Weekly Overtime |
|---|---|---|
| California | After 8 hrs/day | After 40 hrs/week |
| Alaska | After 8 hrs/day | After 40 hrs/week |
| Nevada | After 8 hrs/day | After 40 hrs/week |
| Colorado | After 12 hrs/day | After 40 hrs/week |
| Most States | None | After 40 hrs/week |
Double Time Rules
Some situations require double time (2× pay):
- California: Hours over 12 in a day, or over 8 on the 7th consecutive day
- Some union contracts
- Holiday work policies

Common Work Schedules
| Schedule | Hours/Day | Days/Week | Total Hours |
|---|---|---|---|
| Standard | 8 | 5 | 40 |
| Extended | 10 | 4 | 40 |
| Part-time | 6 | 5 | 30 |
| Part-time | 8 | 3 | 24 |
Calculating Decimal Hours
Time cards often use decimal hours for easier calculation:
| Minutes | Decimal |
|---|---|
| 15 min | 0.25 |
| 30 min | 0.50 |
| 45 min | 0.75 |
| 60 min | 1.00 |
Formula: Decimal Hours = Minutes ÷ 60
Note: Time tracking requirements vary by location and employment type. Consult your HR department or labor laws for specific requirements. This calculator provides estimates and should not be used as official payroll documentation.
