Hours Worked Calculator

How it works

worked = (end − start, +24 h if overnight) − unpaid break · weekly hours = Σ days · overtime = hours over the daily and/or weekly limit · pay = regular h × rate + overtime h × rate × multiplier

For each shift the start is subtracted from the end; if the end is earlier on the clock, the shift ran past midnight and a full day is added. The unpaid break is then taken off, unless you mark breaks as paid. Hours are shown both as hours and minutes and as decimal hours, which is what payroll multiplies by the hourly rate. Enter one shift and how many days a week you work it, or switch to the weekly timesheet to type different hours for each day — including split shifts such as 8:00-12:00, 13:00-17:00. Overtime can follow a weekly limit (40 hours under the US Fair Labor Standards Act), a daily limit, both, or California’s daily 8/12-hour rules; daily overtime is counted first and only the remaining regular hours count toward the weekly limit, so no hour is paid twice. Optional rounding mimics time clocks that round punches to 5, 6 or 15 minutes.

Worked example

Monday to Friday, 9:00 to 17:30 with a 30-minute unpaid break, is 8 hours a day and 40 hours a week. Add Saturday from 9:00 to 13:00 in the weekly timesheet: after the same 30-minute break that day adds 3.5 hours, for 43.5 hours in the week. Under the weekly 40-hour rule, 3.5 of those hours are overtime, so at $20 an hour and 1.5× the gross pay is 40 × $20 + 3.5 × $30 = $905 for the week.
