Pay settings
A weekly time card is how most US hourly employees track the hours they actually worked so payroll can pay them correctly. Enter your clock-in time, clock-out time, and unpaid break for each day of the week, and the calculator totals everything for you — including overtime.
How it's calculated
daily hours = (clock out − clock in) − unpaid break
weekly total = sum of daily hours
regular hours = min(weekly total, OT threshold)
overtime = max(weekly total − OT threshold, 0)
gross pay = regular × rate + overtime × rate × OT multiplier
The overtime threshold and multiplier default to the federal Fair Labor Standards Act (FLSA) values — 40 hours and 1.5x — but both are adjustable so you can model state rules or contract terms. Under the FLSA, non-exempt employees must receive overtime pay of at least 1.5x their regular rate for all hours worked over 40 in a single workweek. The 40-hour threshold is weekly under federal law — there is no federal daily overtime — though some states go further (California, for example, adds daily overtime after 8 hours in a workday). The federal minimum wage floor is $7.25 per hour; many states and cities set higher minimums.
hh:mm vs decimal hours. A time card shows durations two ways. "7:30" means 7 hours and 30 minutes. Payroll systems multiply hours by a pay rate, so they need the decimal form: divide the minutes by 60, so 7:30 = 7.50 hours. The two formats describe the same duration — 7.5 hours at $20/hour is $150 either way. Mixing them up (reading 7:30 as 7.3 hours) shorts you 12 minutes of pay per shift, which adds up fast.
Breaks. Under federal rules, bona fide meal periods (typically 30 minutes or more, fully relieved of duty) can be unpaid, while short rest breaks of about 5–20 minutes are normally counted as paid work time. Only subtract genuinely unpaid breaks on your time card.
Assumptions and limitations. This tool applies the federal weekly overtime rule only; it does not model state daily-overtime rules, double-time, shift differentials, tips, or tax withholding. For take-home pay after federal tax and FICA, use the paycheck calculator.
Frequently asked questions
How is overtime calculated on a weekly time card?
Under the FLSA, non-exempt employees earn at least 1.5x their regular hourly rate for every hour worked over 40 in a workweek. Hours up to 40 are paid at the regular rate; everything above is paid at time-and-a-half.
What is the difference between hh:mm and decimal hours?
"7:30" is 7 hours 30 minutes; in decimal that is 7.50 hours (minutes ÷ 60). Payroll multiplies decimal hours by your hourly rate, so always convert before computing pay — 7:30 is 7.5 hours, not 7.3.
Are lunch breaks paid or unpaid?
Under federal rules, a bona fide meal break (usually 30+ minutes, fully relieved of duties) may be unpaid. Short breaks of roughly 5–20 minutes are normally paid work time and should not be deducted from your time card.
Does overtime apply per day or per week?
Federal law (FLSA) only requires overtime after 40 hours in a workweek. A few states add daily overtime — California, for example, requires 1.5x after 8 hours in a workday — so check your state rules.
How do I convert minutes to decimal hours for payroll?
Divide minutes by 60: 15 min = 0.25, 30 min = 0.50, 45 min = 0.75. So 38 hours 45 minutes is 38.75 decimal hours.
