Summary
This week totals 37.5 hours worked — 37.5 regular and 0 overtime (at 1.5×). At $20.00/hour, that's $750.00 regular pay plus $0.00 overtime pay, for a total of $750.00.

What is a Time Card Calculator?
A time card calculator totals the hours an employee worked across a pay period from their clock-in and clock-out times, subtracts unpaid break time, and splits the result into regular hours and overtime hours based on a weekly threshold. It replaces manually adding up hours and minutes from a paper or digital time card — a process that's easy to get wrong once break deductions and overnight shifts are involved.
Enter each day's time in, time out, and break minutes; the calculator handles overnight shifts automatically (if time out is earlier than time in, it assumes the shift crossed midnight) and computes both your total pay and, if you enter an overtime threshold and multiplier, exactly how much of that pay comes from overtime.

How Time Card Hours Are Calculated
Overtime Hours = max(Weekly Total − Threshold, 0)
Break time is subtracted from each day individually rather than from the weekly total, since unpaid breaks (like a 30-minute lunch) are typically tracked per shift, not per week. Overnight shifts — where the clock-out time is numerically earlier than the clock-in time — are handled by adding 24 hours to the elapsed time, correctly crediting the full overnight duration.
Regular vs. Overtime Pay
Under the US Fair Labor Standards Act (FLSA), non-exempt employees are generally entitled to at least 1.5× their regular rate for hours worked beyond 40 in a single workweek. Some states (notably California) also require daily overtime — for example, time-and-a-half after 8 hours in a single day, regardless of the weekly total — which this calculator doesn't model since it only tracks the standard federal weekly threshold.
Rounding Rules Employers Commonly Use
Many payroll systems round clocked times to the nearest 5, 6, or 15 minutes rather than paying to the exact minute — the FLSA permits rounding as long as it doesn't systematically favor the employer over a long enough period. This calculator computes exact elapsed time from whatever times you enter; if your employer rounds, your actual paycheck may differ slightly from this exact figure.
Unpaid Breaks vs. Paid Breaks
Meal breaks of 30 minutes or more are typically unpaid (and should be subtracted, as this calculator does), while short rest breaks of 5–20 minutes are usually considered paid working time under federal rules and shouldn't be deducted. If your employer counts short breaks as paid, leave the break-minutes field at 0 and only enter true unpaid meal-break time.
Example — Your Current Inputs
This week totals 37.5 hours worked — 37.5 regular and 0 overtime (at 1.5×). At $20.00/hour, that's $750.00 regular pay plus $0.00 overtime pay, for a total of $750.00.
Additional Example — A 45-Hour Week
An employee clocks in at 8:00 AM and out at 5:30 PM five days a week, with a 30-minute unpaid lunch each day — 9 hours worked per day, 45 hours for the week. At $22/hour with a standard 40-hour overtime threshold and 1.5× multiplier: 40 regular hours pay $880, and 5 overtime hours pay 5 × $22 × 1.5 = $165, for a total weekly paycheck of $1,045 — noticeably more than the $990 a flat 45 × $22 calculation (ignoring overtime) would suggest.
About These Parameters
- Time In / Time Out / Break Minutes
- The clocked start and end time for each day worked, plus any unpaid break time to subtract. Uncheck a day to exclude it entirely from the weekly total.
- Hourly Rate
- Your base pay rate per hour, used to compute both regular and overtime pay (overtime pay uses this rate multiplied by the overtime multiplier).
- Overtime Threshold & Multiplier
- The number of weekly hours after which overtime kicks in (40 is the US federal standard) and the pay multiplier applied beyond that threshold (1.5× "time-and-a-half" is most common; some union contracts or holiday policies use 2× "double time").
Frequently Asked Questions
Does this handle overnight shifts?
Yes — if the time-out entered is earlier in the clock than the time-in (for example, in at 10:00 PM and out at 6:00 AM), the calculator assumes the shift crossed midnight and adds 24 hours to correctly compute the elapsed time.
Should I subtract paid rest breaks?
No — only subtract genuinely unpaid time, like a lunch break your employer doesn't pay for. Short paid rest breaks (typically 5–20 minutes) are usually counted as working time under federal rules and shouldn't reduce your paid hours.
Does this calculate daily overtime rules like California's?
No — this calculator only applies the standard federal weekly overtime threshold (over 40 hours/week). States with daily overtime rules (time- and-a-half after 8 hours in a single day, for example) require additional day-by-day logic this calculator doesn't model; check your state's specific labor law if that applies to you.
Why does my actual paycheck differ slightly from this calculation?
Most likely due to time-rounding rules — many payroll systems round clock times to the nearest 5, 6, or 15 minutes rather than using the exact clocked time. This calculator uses your entered times exactly, without any rounding.
