Time Card Calculator

Log a week of clock-in and clock-out times with breaks, or drop in a single day or a total-hours figure, and get net hours worked, overtime and double-time split out, and gross pay if you enter an hourly rate.

For personal planning and general reference — verify important results when needed.

From clock punches to net hours

A time card's job is to turn raw clock-in and clock-out punches into a number payroll can actually use, and breaks are the part that trips up manual math most often. The Daily mode here does the subtraction and break deduction in one pass.

Net hours = (Clock out − Clock in) − Break time

9:00 to 17:30, 30-min lunch: 8.5 hrs − 0.5 hrs = 8.0 hrs

The Weekly mode repeats that same subtraction for each day, then adds every day's net hours together for a full workweek total — the same total that overtime rules get applied to next.

How overtime and double time get layered on top

Under the federal Fair Labor Standards Act, most non-exempt US employees earn 1.5x their regular rate for hours worked beyond 40 in a single workweek — not per day, per week. A handful of states go further, requiring overtime after a set number of hours in a single day, or double time after an even higher threshold.

Gross pay = (Regular hrs × Rate) + (OT hrs × Rate × 1.5) + (DT hrs × Rate × 2)

48 hrs at $20/hr, OT after 40: (40 × 20) + (8 × 20 × 1.5) = 800 + 240 = $1,040

Because thresholds and multipliers genuinely differ by state and by employer policy, the calculator lets both the overtime and double-time thresholds and rates be adjusted rather than hard-coding the federal defaults as the only option.

A note on punch rounding

Some employers round clock punches to the nearest 5, 10, or 15 minutes rather than paying to the exact second. That practice is legal under the FLSA as long as it's applied consistently and doesn't, over time, systematically shortchange the employee — rounding has to average out roughly neutral, not always down. If a workplace uses rounding, punch it into this calculator as already rounded, since the tool itself works from whatever times are entered without applying rounding on its own.

Related time and payroll tools

For a single day's hours-worked math or adding up several time periods without the full payroll layer, the hours calculator covers that more directly, and for general clock-time arithmetic outside of work hours, the time calculator handles everyday time addition, subtraction, and unit conversion.

Frequently Asked Questions

What is a time card?

A time card records clock-in and clock-out times for each work period. Employers use totals for payroll, overtime, and compliance with labor rules.

How is overtime calculated in the US?

Under federal FLSA, non-exempt employees generally earn 1.5× regular rate for hours over 40 in a workweek. State rules may require daily overtime or double time.

Should breaks be deducted from paid hours?

Unpaid meal breaks (typically 30+ minutes) are often deducted. Paid short breaks may count as work time — follow employer policy and local law.

What is rounding in timekeeping?

Some employers round punches to the nearest 5 or 15 minutes within FLSA limits. Rounding must not systematically underpay workers over time.

How do I use this time card calculator?

Enter daily in/out times and break minutes for the week, then click Calculate. Regular hours, overtime, and total pay (if rate entered) appear in the results.

What is the difference between overtime and double time?

Overtime typically pays 1.5x the regular hourly rate once a threshold like 40 hours in a week is crossed. Double time pays 2x the regular rate, and some states require it after a higher weekly threshold or after a very long single shift. Both thresholds and rates vary by state and by employer policy, on top of the federal FLSA baseline.

Does a 30-minute lunch actually cost 30 minutes of pay?

If the break is unpaid, yes: an 8-hour clock-to-clock shift with a 30-minute unpaid lunch nets 7.5 paid hours. Paid short breaks (typically under 20 minutes) usually still count toward hours worked, since the key distinction is whether the break is paid or unpaid, not just how long it lasts.
