Work out the hours you worked: enter your start and finish times for each day, take off unpaid breaks, and get daily and weekly totals in hours and minutes and in decimal hours — with overtime and pay if you add your rate.
Total hours Sep 27, 2026 – Oct 3, 2026
45:15 hours = 45.25 decimal hours

- Overtime hours (1.5×)

How it’s calculated
Hours for a shift = clock-out − clock-in (add 24 hours if the shift ends after midnight) − unpaid break.
Decimal hours = minutes ÷ 60 (7:35 → 7.58).
Gross pay = hours × hourly rate; with overtime on, hours over 40 in a workweek add a half-rate premium (1.5× in total).
Worked example with your numbers
- Mon, Sep 28: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
- Tue, Sep 29: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
- Wed, Sep 30: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
- Thu, Oct 1: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
- Fri, Oct 2: 8:30 AM → 6:15 PM = 9:45, minus 0:30 unpaid break = 9:15 (9.25 h).
- Sat, Oct 3: 9:00 AM → 11:00 AM = 2:00; 12:00 PM → 2:00 PM = 2:00; day total 4:00 (4.00 h).
- Total: 45:15 = 45.25 hours (minutes ÷ 60).
- Workweek Sep 27, 2026 – Oct 3, 2026: 45:15 (45.25 h) worked.
- Weekly rule: regular hours above 40:00 in the workweek → 5:15 (5.25 h) at 1.5×.
- Overtime (1.5×): 5:15 (5.25 h) × 1.5× × $22.00/hr = $173.25.
- Gross pay: $880.00 regular + $173.25 overtime = $1,053.25.
Rounding is allowed under federal rules only when it averages out so employees are paid for all time actually worked over time (29 CFR 785.48). Some states and courts restrict rounding — check your state’s rules.
How to calculate working hours
- Write down the start and finish time for each day (use 24-hour time or AM/PM).
- Subtract the start from the finish time. If a shift ends after midnight, add 24 hours to the finish.
- Take off unpaid breaks, such as a 30-minute lunch.
- Add up the days. Convert minutes to decimal hours (minutes ÷ 60) for payroll: 7 h 45 min = 7.75 hours.
Example: 9:00 AM to 5:30 PM with a 30-minute lunch is 8 hours 30 minutes − 30 minutes = 8 hours. Five such days make a 40-hour week.
Frequently asked questions
How do I calculate hours worked?
Subtract the start time from the end time, take off unpaid breaks, and add the days together. The calculator does this for every day of the week and shows the total.
Are breaks counted as working time?
Under federal rules, short rest breaks (usually 5 to 20 minutes) count as hours worked; bona fide meal periods of 30 minutes or more, when you are fully relieved of duty, generally do not. Some states require meal or rest breaks.
When does overtime start?
Under the FLSA, non-exempt employees earn overtime for hours over 40 in a workweek. Some states also count daily overtime.
