Add up your hours worked from a start and end time. Enter your clock-in and clock-out times and any unpaid break, and see the hours in hours-and-minutes, in decimal, and your pay.
Handles overnight shifts (end time before start time). Break time is subtracted as unpaid. Pay is gross, before taxes.
Subtract your start time from your end time, then take off any unpaid break. This tool does the math — including overnight shifts — and shows the result in hours-and-minutes and as decimal hours (what payroll uses). A 9:00–5:00 shift with a 30-minute break is 7 hours 30 minutes, or 7.5 decimal hours.
Take the end time minus the start time, subtract the unpaid break, and convert to decimal hours by dividing the minutes by 60. Enter your times above and the tool does it, including overnight shifts.
7.5 hours. Payroll uses decimal hours, so 30 minutes = 0.5, 15 minutes = 0.25, and 45 minutes = 0.75.
