Time Card Calculator

Enter your clock-in time, clock-out time, and break duration for each day. The calculator instantly shows your total hours worked, regular hours, and overtime for the week.

How overtime is calculated

Overtime is calculated on a per-day basis using the standard 8-hour daily threshold. Any hours beyond 8 in a single day count as overtime. You can add or remove days as needed, and the totals update automatically.

Overnight shifts

The calculator handles overnight shifts automatically. If your clock-out time is earlier than your clock-in time (e.g. 10 PM to 6 AM), the tool correctly adds 24 hours to compute the actual worked time.

Tips

Enter break time in minutes (e.g. 30 for a half-hour lunch)

The decimal hours shown are useful for payroll systems that require decimal input

Overtime laws vary by jurisdiction

The US Fair Labor Standards Act (FLSA) requires overtime pay (1.5× regular rate) for hours worked beyond 40 in a workweek for covered non-exempt employees. However, some states have additional requirements:

California: daily overtime after 8 hours in a workday; double time after 12 hours in a day or after 8 hours on the 7th consecutive day in a workweek.
Alaska and Nevada: also require daily overtime after 8 hours.

This tool calculates overtime based on weekly hours only (40-hour threshold). Consult your state's labor laws or a payroll professional for jurisdiction-specific requirements.

Time rounding rules

Some employers round time entries to the nearest 6 minutes (1/10 of an hour) or 15 minutes. Under the DOL's 7-minute and 7.5-minute rounding rules, rounding is permissible only if it averages out fairly for employees over time - systematic rounding that always benefits the employer is not compliant.

This tool uses exact times as entered with no rounding. If your payroll system rounds differently, your final totals may vary slightly.

Gross pay calculation

Once you know your total regular and overtime hours, gross pay is calculated as:

Gross Pay = (Regular Hours × Hourly Rate) + (Overtime Hours × Hourly Rate × 1.5)

Example: 45 hours worked at $20/hr. Regular pay = 40 × $20 = $800. Overtime pay = 5 × $20 × 1.5 = $150. Total gross pay = $950.
