Time Card Calculator
Quickly turn clock-in and clock-out times into hours worked and a day's pay. Decimal-time input, instant result, print-ready for filing.
How to use this calculator
- Enter your clock-in time in 24-hour decimal. 9:00 AM = 9, 12:30 PM = 12.5, 5:45 PM = 17.75.
- Enter your clock-out time. Same format. (If you worked past midnight, split the day at midnight and run the calculator twice.)
- Enter any unpaid break in minutes — most jobs deduct a 30-minute lunch.
- Optionally add your hourly rate to see what the shift earned.
- The result updates as you type. Use Share to send your hours to a manager, or Print / Save PDF to file the timesheet.
How the math works
Two practical notes: federal law (FLSA, 29 CFR §785.18) says short breaks of 5-20 minutes must be paid and aren't subtracted. Bona-fide meal periods of 30+ minutes can be unpaid only if the employee is completely relieved of duty. If you're answering phones during lunch, that's working time and your employer owes you for it.
Tips
- Keep your own timesheet. If a pay dispute ever comes up, the employee's contemporaneous record (a notebook, a notes app, even photos of the time clock) is strong evidence. Don't rely on the employer's system being the only record.
- "Rounding" cuts both ways. Employers can round time to the nearest 5, 10, or 15 minutes under FLSA — but only if it averages out and doesn't systematically shortchange the worker. Rounding that always rounds down is illegal.
- Travel during the workday is paid. If you have to drive between job sites or to a client during your shift, that's compensable time. Commuting to and from your first/last site is generally not.
- State laws can add to FLSA. California requires a 30-min meal break by hour 5 and another by hour 10. Failure to provide triggers a penalty hour of pay. Several other states have similar premiums.
Frequently asked questions
How do I enter time in this calculator?
Use 24-hour decimal format. 9:00 AM = 9, 12:30 PM = 12.5, 5:45 PM = 17.75. So a typical 9-to-5 shift is 9 and 17. If math with decimals is confusing, use the hours-to-decimal converter on this site first.
Does this calculator handle overnight shifts?
Not directly. For shifts that cross midnight, run the calculator twice — once for hours before midnight (e.g., 22 to 24 for 10 PM to midnight) and once for hours after (e.g., 0 to 6 for midnight to 6 AM) — and add the results.
Should unpaid breaks always be subtracted?
Only meal periods of 30+ minutes where you're completely relieved of duty. Short breaks (5-20 min) are paid working time under FLSA and shouldn't be subtracted. If you have to keep your phone on or watch the front desk during lunch, that lunch is paid time.
Is daily overtime included?
No. This is a single-day time card. For weekly FLSA overtime (over 40 hrs), use the payroll time calculator. For California-style daily overtime (over 8 hrs in a day), check your state's labor department.
