Quick answer: for each day, subtract time in from time out, then subtract unpaid lunch. 8:00 AM to 4:30 PM with a 30-minute lunch is 8:00 hours. Add the days for the week total; hours over 40 in the week are overtime under federal law.
What this time card does that others do not
- A card for every employee or job, kept in your browser with no account; download one CSV for all of them.
- Share link: send the whole card to a manager or payroll as a link; it opens exactly as you filled it.
- Your overtime rules: federal, California, or custom daily and weekly limits and multipliers.
- Split shifts, paid leave and rounding up, down or to the nearest 5, 6, 10, 15 or 30 minutes.
- Tap the clock to stamp the current time, and it keeps working without a signal once you have opened it.
How to use the time card calculator
- Pick the first day of your workweek. Many US employers use Sunday to Saturday, but the workweek can start on any day and any hour.
- Type each time in and time out. If you clock out for lunch, fill in lunch out and lunch in; if your break is deducted automatically, switch Breaks to deduct minutes.
- Add your hourly rate to see gross pay, and pick the overtime rule that applies to you.
- Print the card, copy the summary, or download a CSV.
Worked example
Monday to Friday, 8:00 AM to 5:30 PM with a 30-minute lunch, is 9 hours a day and 45 hours for the week. At 20 an hour: 40 regular hours x 20 = 800, plus 5 overtime hours x 30 = 150, so 950 gross. The same week in decimal is 45.00 hours; see the time to decimal chart for single days such as 7:45 (7.75).
Keep your time cards
Federal rules require employers to record the hours worked each workday and the total for each workweek (29 CFR 516.2), keep time cards for at least 2 years and payroll records for at least 3 (29 CFR 516.5 and 516.6). Keeping your own copy of each week is the easiest way to check a paycheck. Download the CSV or print the card each week.
Paid every two weeks? Use the biweekly time card. Need a paper card instead? Print the blank time card.
Need a blank card for the wall instead? Print the printable time card. Working out what the overtime hours pay? The time and a half calculator shows the 1.5x rate, and the military time chart helps if your clock prints 24-hour punches.
Overnight shifts on the two nights a year when clocks change are an hour shorter (March) or longer (November) than the clock times suggest; federal rules pay the hours actually worked, so adjust that one shift by hand.

Questions
How do I calculate hours worked on a time card?
For each day, subtract the time in from the time out, then subtract any unpaid lunch or break. 8:00 AM to 4:30 PM with a 30-minute lunch is 8 hours 30 minutes minus 30 minutes, or 8:00. Add the days together for the week.
What if a shift goes past midnight?
Enter the times as they are, for example 10:00 PM in and 6:30 AM out. When the time out is earlier than the time in, the calculator treats it as the next day, so that shift is 8 hours 30 minutes, counted on the day it started.
Which overtime rule should I choose?
Most US workers are covered by the federal rule: over 40 hours in a workweek is overtime. Choose the California-style setting only if your state has daily overtime. The overtime calculator explains the rules.
Is my data saved or sent anywhere?
No account and no server. Your entries are saved only in this browser so the card is still there when you come back. Clear all removes them.
How do I calculate payroll hours?
Total each employee's hours worked for the workweek, split them into regular hours (up to 40) and overtime hours, and convert both to decimal hours for payroll. The calculator shows all three.
