Frequently asked questions
How do I calculate hours worked?
Subtract the start time from the end time and then subtract unpaid breaks. From 9:00 to 17:30 with a 30 minute lunch is 8 hours 30 minutes minus 30 minutes, so 8 hours. Add up every day for the weekly total.
How do I convert minutes to decimal hours?
Divide the minutes by 60. 15 minutes is 0.25 hours, 30 minutes is 0.5 and 45 minutes is 0.75, so 7 hours 45 minutes is 7.75 decimal hours. Payroll multiplies the decimal figure by the hourly rate.
How do I calculate hours for a shift that goes past midnight?
Add 24 hours to the end time before subtracting. A shift from 22:00 to 06:00 becomes 30:00 minus 22:00, which is 8 hours. This calculator does it automatically whenever the end time is earlier than the start.
How is overtime pay calculated?
Hours above the weekly threshold are paid at the overtime multiplier. Under US federal law that is 1.5 times the regular rate after 40 hours in a workweek, so 45 hours at $20 pays 40 x $20 plus 5 x $30, which is $950. Some states and contracts also count daily overtime, which this calculator does not.
Are breaks counted as hours worked?
Short rest breaks of 5 to 20 minutes are usually paid, while meal breaks of 30 minutes or more when you are fully relieved of duty are usually unpaid. Only enter the unpaid part of your breaks in the break column.
