Enter daily start and end times for a week and calculate total hours, overtime, and pay automatically.
A workweek in, a paycheck-math problem out: give this tool a start and end time for each day plus your hourly rate, and it returns total hours, overtime hours, regular pay, overtime pay, and gross pay. It works in decimal hours - a shift of 8 hours 30 minutes shows as 8.5, and reading that as 8 hours 5 minutes is the classic mistake. Anything past 40 hours is split off at 1.5 times the rate - check that part: the 40-hour, time-and-a-half model is the U.S. federal default, not every employer's rule. Everything runs in the browser; your times and rates are not uploaded anywhere.
A concrete input and expected output from the current implementation.
Input
Hourly rate: $20.00 Mon 09:00-17:00 Tue 09:00-17:30 Wed 09:00-17:00 Thu 09:00-17:00 Fri 09:00-17:00
Expected output
Total hours: 40.5 (regular 40.0, overtime 0.5) Regular pay: $800.00 Overtime pay: $15.00 Gross pay: $815.00
Five 8-hour days sum to 40 hours, and Tuesday's extra half hour lands on top, so 0.5 of the week's 40.5 hours counts as overtime. At 1.5 times the $20 rate, that half hour pays $15, added to $800 for the 40 regular hours, for $815 gross.
The tool reads the start and end time you enter for a day, measures the gap in minutes, and writes that shift as a fraction of an hour: 09:00 to 17:30 becomes 8.5. It then adds the seven daily values. A shift that crosses midnight, like 23:00 to 07:00, has to be counted as an overnight span, or the subtraction runs negative and that day poisons the week's total.
The tool adds the week's decimal hours and compares the total to a regular-hours threshold, 40 by default. Hours above it are overtime, paid at the multiplier, 1.5 by default; the rest is paid at the base rate. It reports the split as regular hours, overtime hours, regular pay, overtime pay, and gross. Both are the U.S. federal standard, a floor, not the only rule in use.
Because that gap is 8 hours 30 minutes, and the tool writes minutes as fractions of an hour: 30 divided by 60 is 0.5, so the shift is 8.5 hours, not 8 hours 5 minutes. To read any result, multiply the fractional part by 60: 0.75 x 60 = 45, so 8.75 hours is 8 hours 45 minutes.
Maybe, but check the hours before the pay. The tool counts overtime as hours past 40 in one week at 1.5 times the rate, the U.S. federal model. If your employer uses a different multiplier, daily overtime, or a different pay period, the totals will differ even with identical times. The tool cannot know your employer's rules, so treat its overtime line as a check, not a verdict.
