How to use this calculator

For each day worked, enter your start and end times. Leave days off blank.
Enter unpaid meal breaks in minutes. Don't enter short paid breaks.
Optionally add your hourly rate, and tick the overtime box if you're a nonexempt employee.
Select Calculate.

How it works

Hours for a day = (end time − start time) − unpaid break

Decimal hours = total minutes ÷ 60

Gross pay = regular hours × rate + overtime hours × rate × 1.5

If an end time is earlier than the start time, the shift is treated as running past midnight. For example, 10:00 PM to 6:00 AM is 8 hours.

The calculator adds exact minutes and converts to decimal hours only at the end, so rounding doesn't build up. Pay is worked out from the exact minutes, and each pay line is rounded to the cent, so the lines always add up to the total.

When you tick the overtime box, hours over 40 in the week are paid at 1.5 times the rate you entered. Under federal law the overtime rate is based on the regular rate of pay, which can include things like nondiscretionary bonuses, so actual overtime pay can be higher.

Worked example

Sam works Monday to Friday, 8:30 AM to 5:15 PM, with a 30-minute unpaid lunch, and earns $21.00 an hour.

Step	Result
Each day: 8h 45m − 30m	8h 15m
Week: 8h 15m × 5	41h 15m (41.25 hours)
Regular pay: 40 × $21.00	$840.00
Overtime pay: 1.25 × $21.00 × 1.5	$39.38
Gross pay	$879.38

Frequently asked questions

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 hours.

Should I subtract my breaks?

Only unpaid meal breaks. Under federal rules, short rest breaks of usually 20 minutes or less count as hours worked. Bona fide meal periods, typically 30 minutes or more when you're fully relieved from duty, generally don't. Some states have their own break rules.

How does the calculator handle overnight shifts?

If the end time is earlier than the start time, it assumes the shift crossed midnight and adds 24 hours to the end time. A shift from 10:00 PM to 6:00 AM counts as 8 hours.

When does overtime apply?

Under the federal Fair Labor Standards Act, covered nonexempt employees must get at least 1.5 times their regular rate for hours over 40 in a workweek. The workweek is any fixed, recurring seven-day period. It doesn't have to start on Monday, and hours can't be averaged across weeks. Some states, such as those with daily overtime, have stricter rules. Exempt employees aren't covered by this rule.

Does the federal law require overtime for weekends or holidays?

No. The Department of Labor says the FLSA doesn't require overtime pay for weekends, holidays or regular days of rest, unless the hours worked go over 40 in the workweek. Extra pay for weekends or nights is a matter of agreement between employer and employee.

Hours are added with simple arithmetic. The optional overtime calculation follows the federal rule described by the Department of Labor.

U.S. Department of Labor: Overtime pay. Unless exempt, covered employees must receive at least time and one-half their regular rate for hours over 40 in a workweek. The workweek is a fixed, recurring period of 168 hours. Some states have their own overtime laws.
U.S. Department of Labor: Fact Sheet #22, hours worked. Short rest periods, usually 20 minutes or less, count as hours worked. Bona fide meal periods, typically 30 minutes or more, generally don't.
U.S. Department of Labor: Breaks and meal periods. Federal law doesn't require breaks, but short breaks that are offered count as work time.
