Hours worked from clock-in and clock-out times, less breaks: weekly total and overtime
Estimates only, not financial advice. What you type stays on your device. Checked against sources on 5 Oct 2026.Hours worked are the time from clock-in to clock-out less unpaid breaks, added up for the week. Monday to Friday from 8:30 to 17:30 with a 30-minute lunch is 42.5 hours, so 2.5 hours are overtime above the 40-hour federal line. At $20 an hour the week pays $875.
Rates and rules read from the sources listed on this page (the earliest on 5 Oct 2026); they may have changed since.
Switch on each day you worked and type the start and end time, for example 08:30 and 17:30.
Enter the unpaid break for that day in minutes, such as a 30-minute lunch.
Read the week’s total in hours and minutes and in decimal hours at the top of the result.
Hours over 40 show as overtime; open them in the Overtime Calculator with one tap.
The Work Hours Calculator turns a week of start and finish times into hours worked, the way a payroll clerk would. Each day is the time from clock-in to clock-out less the unpaid break, and the week is the sum of the days. The total is shown in hours and minutes (42:30) and in decimal hours (42.5), because time cards use one and payroll the other.
Night shifts. When the finish time is earlier than the start, the shift is treated as ending the next morning, so 22:00 to 06:30 counts as 8.5 hours before the break. A day off is switched off rather than left at zero.
Breaks. Enter only unpaid breaks. Under the Fair Labor Standards Act, short rest breaks of about 20 minutes or less are normally paid working time, while a real meal break of 30 minutes or more, with no duties, usually is not (U.S. Department of Labor Fact Sheet #22). If you clock out for lunch, enter the lunch as a break rather than splitting the day into two rows.
Overtime. Federal law pays covered employees at least time and a half for hours over 40 in a fixed seven-day workweek, and hours cannot be averaged over two weeks (Fact Sheet #23). The threshold and multiplier are editable for contracts that pay more. With an hourly rate entered, the page shows regular pay, overtime pay and the total, and one link opens the same figures in the Overtime Calculator.
What it does not do. Daily overtime rules such as California's over 8 hours a day, punch rounding, shift premiums, tips, and whether you are exempt from overtime are not covered. Pay is before tax; for take-home pay, use the US Income Tax Calculator.
Subtract the start time from the finish time, then take off the unpaid lunch. From 8:30 to 17:30 is 9 hours; less a 30-minute lunch that is 8.5 hours. Do the same for each day and add them up: five such days come to 42.5 hours for the week.
Divide the minutes by 60 and add them to the hours. 8 hours 15 minutes is 8.25, 8 hours 30 minutes is 8.5 and 8 hours 45 minutes is 8.75. A shift of 8 hours 1 minute is 8.017, shown as 8.02. Payroll systems usually multiply decimal hours by the hourly rate.
Count from the start to midnight and from midnight to the finish. A shift from 22:00 to 06:30 is 2 hours before midnight plus 6.5 after, 8.5 hours in total. The calculator does this automatically whenever the finish time is earlier than the start time.
Under the federal Fair Labor Standards Act, short rest breaks of about 20 minutes or less are normally paid and count as hours worked. A bona fide meal period of 30 minutes or more, with no duties, usually does not. Some states set their own break rules, so check your state labor department.
Federal law requires at least one and a half times the regular rate for hours over 40 in a workweek, a fixed period of seven consecutive days. Hours cannot be averaged across two weeks. California and a few other states also pay overtime after 8 hours in a day, which this calculator does not apply.
Each week is calculated on its own, because federal overtime is counted per workweek. For a two-week pay period, total each week separately and add them. For two jobs with different employers, keep separate timesheets: each employer counts only its own hours for overtime.
