This free hours worked calculator totals a full week's timesheet from your clock-in and clock-out times. Enter each day's start and end, deduct unpaid breaks, choose a rounding rule if your employer uses one, and get the weekly total in both hours-and-minutes and decimal hours — plus gross pay if you add a rate.
Built by Anchor AI Tools, it works as a time card calculator for payroll, a work hours calculator for freelancers billing clients, and a quick way for employees to check their own hours against a pay stub.
Quick Answer: To calculate hours worked, convert the clock-in and clock-out times to a 24-hour format, subtract the start from the end to get the time on the clock, then subtract any unpaid break. For example, 9:00 to 17:30 with a 30-minute lunch is 8.5 hours on the clock minus 0.5 = 8 hours worked. Add each day for the weekly total, then multiply the decimal hours by your hourly rate for gross pay.

24-hour or AM/PM time pickers. Break is in minutes and is unpaid.
Enter clock-in and clock-out for each day. Use the time pickers; leave days you did not work blank.
Add unpaid breaks in minutes. A 30-minute lunch is entered as 30. Paid breaks are left out.
Pick a rounding rule. Use Exact for digital clocks, or match your employer's rule (commonly nearest 15 minutes).
Add an hourly rate (optional). The calculator multiplies your decimal total by the rate for gross pay.

How Hours Worked Are Calculated
Hours Worked = (Clock Out − Clock In) − Unpaid Break
Each day is totalled, then summed for the week
The calculator converts each clock time to minutes since midnight, subtracts clock-in from clock-out to find the time on the clock, then subtracts the unpaid break. If a shift crosses midnight (clock-out earlier than clock-in), it adds 24 hours so an overnight shift totals correctly. Each day's minutes are added for the week, then converted to decimal hours by dividing by 60.
Convert to 24-hour time. 5:30 PM becomes 17:30.
Subtract start from end. 17:30 − 9:00 = 8 hours 30 minutes on the clock.
Convert to decimal and total. 8:00 = 8.00 decimal hours; repeat for each day and add.
Time Clock Rounding and the 7-Minute Rule
Many employers round clock times to a set interval. Under the U.S. Department of Labor's interpretation of the Fair Labor Standards Act, time may be rounded to the nearest 5 minutes, the nearest tenth of an hour (6 minutes), or the nearest quarter hour (15 minutes), provided the rounding does not consistently favour the employer.
The best-known method is the 7-minute rule for quarter-hour rounding: time from 1 to 7 minutes past an interval rounds down, and time from 8 to 14 minutes rounds up to the next quarter hour. So a punch at 8:07 is treated as 8:00, while 8:08 becomes 8:15. The calculator above applies your chosen rounding to each clock-in and clock-out before totalling.

Worked Weekly Example
📋 A standard work week at $25/hour
Each day is 9:00 to 17:30 with a 30-minute unpaid lunch — that is 8.5 hours on the clock minus 0.5 = 8.00 hours worked per day, across five days.

40.08
The week totals 40.08 decimal hours (displayed rounded). Using the exact value for pay, 40.0833 × $25 = $1,002.08 gross. Entering the times wrong as plain clock numbers would miscount the partial hours on Tuesday and Friday.
An hours worked calculator totals each day, deducts breaks, and gives the weekly decimal hours for payroll.
How to Calculate Hours Worked in Excel or Google Sheets
With clock-in in cell A2 and clock-out in B2, both stored as time values, subtract and multiply by 24 for decimal hours, then subtract the break:
// Sum the week (D2:D8 are daily decimal totals) =SUM(D2:D8)
Format the daily cells as Number with two decimals, not Time. For overnight shifts where clock-out is the next day, add 1 before multiplying: =((B2 - A2 + 1) * 24). To convert any single value, use the minutes to decimal converter.
