Pay & work

Time Card Calculator

Add up a week of shifts with breaks, split regular from overtime at your threshold, and total the pay, overnight shifts handled.

Quick answer

Enter each shift's start, end and break; hours past the weekly threshold (40 under the US federal rule) pay at the overtime multiplier, typically 1.5×. A 46-hour week at $20 pays $800 regular + $180 overtime = $980.

What the calculator does

Each row is a shift: start, end, unpaid break. The calculator subtracts the break, handles shifts that cross midnight, totals the week, splits regular from overtime hours at your threshold, and prices the whole thing at your rate and overtime multiplier. The arithmetic is trivial in principle and error-prone in practice, minutes are base-60, weeks span midnight, and a fifteen-minute slip per week is thirteen hours a year.

A worked week

$20/hour, 40-hour weekly threshold, 1.5× overtime:

DayShiftBreakHours
Mon8:00 – 17:300:309.0
Tue8:00 – 17:300:309.0
Wed8:00 – 17:300:309.0
Thu8:00 – 17:300:309.0
Fri8:00 – 18:300:3010.0

Total: 46 hours. The first 40 pay $800; the 6 overtime hours pay $20 × 1.5 = $30 each, $180. Week's gross: $980. Notice the overtime hours are 13% of the time but 18% of the pay, the multiplier is why accurate splitting matters.

The overtime rules, briefly and honestly

  • US federal (FLSA): over 40 hours in a workweek → at least 1.5× the regular rate, for non-exempt employees. The workweek is any fixed 168-hour cycle the employer defines.
  • State law can add more: California pays 1.5× past 8 hours in a day and 2× past 12, independent of the weekly total. Alaska and Nevada have daily rules too. The stricter of state and federal applies. This calculator implements a weekly threshold, if you are in a daily-overtime state, treat its output as the federal floor, not the final answer.
  • Exempt vs non-exempt: salaried-exempt roles (executive, administrative, professional tests, plus a salary minimum) get no overtime at all, which is a real factor when comparing offers.

Overnight shifts and other traps

An end time earlier than the start time means the shift crossed midnight: 22:00 to 6:00 is 8 hours, and the calculator adds the day automatically. The subtler questions are policy, not arithmetic, which workday an overnight shift's hours belong to, and when the workweek resets, and the answer is whatever boundary the employer has defined, applied consistently. If your paystub's split disagrees with your own count, the workweek definition is the first place to look.

From time card to bigger decisions

A time card is the raw truth of what a job pays; most pay decisions need it converted. Steady hours translate to annual figures in the salary calculator, and a 46-hour week at $20 with overtime ($50,960/year) is the number a salaried offer has to clear, not $41,600. If the hours are irregular and you are effectively freelancing, the freelance rate calculator accounts for the unbillable time a timesheet never shows. And for counting workdays until a deadline or a pay period boundary, the days between dates calculator does the calendar part.

Frequently asked questions

How are time card hours calculated?

Each shift is end time minus start time, minus unpaid breaks. A 9:00–17:30 shift with a 30-minute lunch is 8 hours paid. The week’s shifts are summed, hours past the overtime threshold are split out, and pay is regular hours × rate plus overtime hours × rate × multiplier. The calculator does the minute arithmetic that mental math reliably fumbles.

How does overtime pay work in the US?

The federal FLSA rule: hours beyond 40 in a workweek are paid at no less than 1.5× the regular rate. A 46-hour week at $20/hour pays 40 × $20 = $800 regular plus 6 × $30 = $180 overtime, $980 total. Note the threshold is weekly, not daily, under federal law, and it applies to non-exempt employees; salaried-exempt roles fall outside it.

Do any states have daily overtime?

Yes, state law can be stricter than federal, and where it is, the stricter rule wins. California is the big one: over 8 hours in a day earns 1.5×, over 12 hours earns 2×, and the seventh consecutive workday has its own rules. A few other states (Alaska, Nevada, Colorado in some cases) also have daily thresholds. Check your state; this calculator applies a weekly threshold.

How do overnight shifts get counted?

A shift that starts at 22:00 and ends at 6:00 crosses midnight; the calculator recognises the end time being earlier than the start and adds 24 hours, giving 8 hours worked. For which day the hours belong to, employers pick a fixed workday boundary and apply it consistently, what matters for overtime is the total within the defined workweek, wherever midnight falls.

Are breaks paid or unpaid?

Under US federal rules, short breaks of roughly 5–20 minutes are generally counted as paid work time, while bona fide meal periods of 30+ minutes, where you are fully relieved of duty, can be unpaid. Enter only unpaid breaks in the break column. State rules again layer on top, California, for instance, mandates meal and rest breaks with penalty pay when they are missed.

How do I convert my weekly hours into an annual salary figure?

Steady weekly hours × hourly rate × 52 gives the annual equivalent, 40 hours at $20 is $41,600. But regular overtime breaks the simple conversion: a consistent 46-hour week at $20 with 1.5× overtime is $980 × 52 = $50,960, which is what a salary offer must beat before it is actually a raise. Run both numbers before accepting a switch to salaried.
