Hours summary
Gross pay
This calculator is for informational purposes only and does not constitute medical advice. Results are estimates based on general formulas. Consult a qualified healthcare professional before making health decisions.
A time card calculator turns clock-in and clock-out times into total hours, regular vs overtime split, and gross weekly pay. Useful for hourly employees verifying paychecks, freelancers tracking client hours, and anyone curious whether their week was actually 40 hours or 47.
How weekly hours and overtime are calculated
Daily hours = clock-out − clock-in − unpaid breaks. Total hours = sum across the week. Federal FLSA defines overtime as hours over 40 per workweek, paid at 1.5× regular rate. Some states (California, Alaska, Nevada) also require daily overtime over 8 or 12 hours. Gross pay = (regular hours × rate) + (OT hours × rate × OT multiplier).
When to use this calculator
Use it to double-check your paycheck — payroll errors are surprisingly common, and most affect the OT calculation. Use it as a freelancer or consultant to bill clients accurately. Use it before negotiating a flat rate to know what your effective hourly rate would be at typical hours worked.
Worked example
A retail worker logs 9-5 with 30-minute unpaid breaks Mon-Fri (7.5 hours × 5 = 37.5) plus a 5-hour Saturday shift = 42.5 total hours. At $20/hour with 1.5× OT over 40: regular 40 hrs × $20 = $800. OT 2.5 hrs × $30 = $75. Gross weekly pay: $875.
Limits and assumptions
Hours for each day are the time between clock-in and clock-out minus the break you enter, shown to two decimal places. If the clock-out time is earlier than the clock-in time the shift is treated as overnight and 24 hours are added. Weekly overtime is every hour above the threshold you set (40 by default), paid at the multiplier you set (1.5× by default, adjustable in 0.25 steps) on the hourly rate.
Only a single weekly threshold is applied. Daily overtime rules such as California's, double-time tiers and seventh-day rules are not modelled, a single shift longer than 24 hours is not supported, and gross pay is before any tax or deduction.
Frequently asked questions
How do I calculate hours worked from clock-in and clock-out times?
Subtract clock-in time from clock-out time, then subtract any unpaid breaks. For overnight shifts, add 24 hours to the clock-out time before subtracting. The calculator handles both automatically.
How is overtime pay calculated?
Federal law (FLSA) requires 1.5× the regular rate for hours over 40 in a workweek for non-exempt employees. Some states have daily overtime rules too — California, for example, requires 1.5× over 8 hours/day and 2× over 12 hours/day.
Does the time card calculator handle overnight shifts?
Yes. If your clock-out time is earlier than your clock-in time, the calculator assumes you crossed midnight and adds 24 hours.
Should I include lunch breaks?
In the US, unpaid breaks of 30+ minutes generally aren't counted toward worked hours. Short paid rest breaks (5-15 minutes) typically are. Subtract any unpaid break time in the "break" field.
