The formula
How it works
Turn a daily clock-in and clock-out into weekly hours and pay. Enter your start and end times, any unpaid break, your hourly rate and how many days a week you work this shift.
FAQ
Does it handle overnight shifts?
Yes. If the clock-out time is earlier than the clock-in time, the calculator assumes the shift runs past midnight and adds the extra day, so a 22:00 to 06:00 shift comes out as eight hours, not a negative.
Is the break paid or unpaid?
The break is treated as unpaid and subtracted from the shift, which is the usual arrangement. If your break is paid, simply enter 0 so the full clock-in to clock-out time counts towards your hours and pay.
How do I total more than one break?
Add the lengths of all your unpaid breaks together and enter that combined number of minutes in the break field — the calculator only takes a single total, not separate entries for each one.
Does it calculate overtime pay?
No, it applies your one hourly rate to every hour worked. If any hours qualify for an overtime premium, work those out separately and add the extra pay to the weekly total shown here.
Does it round to the nearest quarter hour?
No, it uses the exact clock-in and clock-out times you enter. Some employers round punches to the nearest 15 minutes for payroll, so check your workplace policy if your pay slip does not match exactly.
What if my hourly rate changes on different days?
Run the calculator once per rate, entering the shift and the days worked at that rate, then add the weekly pay figures together for a combined total.
Can I use it for a part-time or irregular schedule?
Yes, as long as the shift length is the same each day you work — just set the days-per-week field to however many days you actually work that shift, rather than a full five.
About the time card calculator
This calculator turns a shift — a clock-in time, a clock-out time and an unpaid break — into the hours worked and, with an hourly rate, the pay. It then scales a single day up to a working week. It is the sum behind a paper or digital time card, and doing it by hand means juggling a 60-minute hour, an overnight shift and a rate all at once, which is exactly where mistakes and pay disputes creep in.
How to use it
Enter the clock-in and clock-out times, the length of any unpaid break in minutes, your hourly rate and the number of days a week you work the shift. The calculator shows the daily hours, weekly hours and weekly pay. For example, 9:00 to 17:30 with a 30-minute break is 8 hours a day; at $20 an hour over 5 days that is $800 a week.
The formula
Daily hours are the clock-out minus the clock-in, minus the break, all in minutes and divided by 60; if the clock-out is earlier, a day of 1,440 minutes is added for the overnight case. Pay is then . Weekly hours are simply the daily hours times the number of days, so both totals scale directly with how many shifts you enter.
Where it is used
Hourly employees use it to check that a pay slip matches the hours they worked, and small businesses use it to add up staff time cards before running payroll. Freelancers and contractors use it to convert logged shifts into an invoice total. Wherever pay depends on hours rather than a fixed salary, a quick and accurate time card total protects both sides from underpaying or overpaying.
