Time Card Calculator (Weekly Hours / Overtime)
Calculate total weekly hours, overtime, and gross pay from daily time entries.
Enter hours worked each day and your hourly rate to see regular and overtime pay.
Time card calculations involve two steps: totaling hours worked, then splitting them between regular and overtime.
The US federal standard (FLSA) requires overtime pay for any hours worked over 40 in a workweek. Overtime rate is 1.5× the regular rate — often called “time and a half.”
Regular pay = min(40, total hours) × hourly rate Overtime hours = max(0, total hours - 40) Overtime pay = overtime hours × hourly rate × 1.5 Gross pay = regular pay + overtime pay
California and several other states use a stricter daily overtime rule: any hours over 8 in a single day are overtime, and any hours over 12 in a day are paid at double time (2×). Under California rules, even if a worker puts in exactly 40 hours total, they earn overtime if any single day exceeded 8 hours.
Daily OT (California-style):
- Hours 1-8 per day: regular rate
- Hours 9-12 per day: 1.5× rate
- Hours over 12 per day: 2× rate
- Any hours on 7th consecutive day: 1.5× first 8 hours, 2× beyond that
For this calculator, you can choose either the federal (weekly OT) or California (daily OT) rule.
Employers must also track breaks. The FLSA does not require paid meal breaks of 30+ minutes. Short rest breaks (5-20 minutes) are generally counted as paid time. Enter only the hours you were actually clocked in or available to work.
