Time Card Calculator
Clock in, clock out, subtract lunch. Weekly or biweekly.
Every total comes in hours and minutes and in the decimal hours payroll asks for.

Gross pay is hours × rate. It does not apply an overtime multiplier, and it takes out no taxes or deductions.
Why 7 hours 20 minutes is 7.33 and not 7.20
This is where most hand-written time cards go wrong. Minutes run to 60, money runs to 100, and payroll software only understands the second one. Twenty minutes is a third of an hour, so it goes in as 0.33 — not 0.20. Get that wrong on five shifts a week and you have talked yourself out of about an hour of pay.

Lunch breaks, and which ones you actually deduct
A break only comes off the card if it is unpaid and you are genuinely free of duty. Under federal rules short rest breaks — the ten or fifteen minutes for coffee — count as hours worked and stay on the clock. A real meal break, usually thirty minutes or more with no work expected, is the one you subtract.
Eating at your desk while answering the phone is not a meal break. If work keeps arriving, the time is paid, whatever the schedule says. Set the break column to zero on those days.
Overtime is counted by the week, not the pay period
Two weeks of 35 and 45 hours average out to 40 — and you are still owed five hours of overtime. The FLSA counts each workweek on its own, so a light week never cancels a heavy one. That is why the biweekly view keeps a separate 40-hour line per week instead of one line for the whole period.
States can be stricter. California adds daily overtime after 8 hours and double time after 12; Alaska, Nevada and Colorado have daily rules of their own. The calculator uses the federal weekly threshold, so treat the split as a starting point and check your state before payday.
How to Use
Pick the pay period
Weekly gives you one Monday-to-Sunday card. Biweekly adds a second week below it, each with its own overtime line.
Enter start and end times
Leave days off blank. A shift that ends before it starts is read as an overnight shift, so 22:00 to 06:00 comes out as eight hours.
Set the unpaid break
Type it per day, or use the buttons above the table to apply the same break to the whole week in one click.
Add your hourly rate
Optional. It turns the decimal total into gross pay — hours times rate, before any overtime multiplier and before tax.
Frequently Asked Questions
How do I calculate hours worked with a lunch break?
Subtract the unpaid break from the span between clock-in and clock-out. A 9:00 to 17:30 shift is 8 hours 30 minutes; take away a 30-minute lunch and you are paid for 8 hours.
What are decimal hours and why does payroll want them?
Decimal hours express minutes as a fraction of an hour, so 7 hours 30 minutes becomes 7.5. Payroll multiplies by the hourly rate and cannot do that with a value written as 7:20. Every total here is shown both ways.
Can I calculate a two-week (biweekly) time card?
Yes — switch the pay period to Biweekly and a second week appears. Each week keeps its own 40-hour overtime line.
Does it handle an overnight shift that crosses midnight?
Yes. An end time earlier than the start time is read as a shift running past midnight, so 22:00 to 06:00 counts as eight hours rather than a negative number.
How is overtime calculated?
The overtime line follows the federal FLSA rule: anything past 40 hours in a single workweek. Several states add daily rules of their own, so check yours before you rely on the split.
Does the gross pay figure include taxes?
No. Gross pay is hours multiplied by your hourly rate — no overtime multiplier, no withholding. Treat it as a check on the hours, not a paycheck estimate.
Is my time card data saved anywhere?
No. Everything is calculated in your browser and nothing is sent to a server or kept between visits. Close the tab and the entries are gone.
Timing the work, not just counting it
A time card tells you what happened after the fact. If you would rather see the clock while you work, the stopwatch measures a single task down to the millisecond, and the Pomodoro timer breaks a shift into focused blocks. For a hard stop at the end of the day, set the alarm.
