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

  1. Mon, Sep 28: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
  2. Tue, Sep 29: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
  3. Wed, Sep 30: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
  4. Thu, Oct 1: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
  5. Fri, Oct 2: 8:30 AM → 6:15 PM = 9:45, minus 0:30 unpaid break = 9:15 (9.25 h).
  6. 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).
  7. Mon, Oct 5: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
  8. Tue, Oct 6: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
  9. Wed, Oct 7: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
  10. Thu, Oct 8: 8:30 AM → 5:00 PM = 8:30, minus 0:30 unpaid break = 8:00 (8.00 h).
  11. Fri, Oct 9: 8:30 AM → 6:15 PM = 9:45, minus 0:30 unpaid break = 9:15 (9.25 h).
  12. Sat, Oct 10: 9:00 AM → 11:00 AM = 2:00; 12:00 PM → 2:00 PM = 2:00; day total 4:00 (4.00 h).
  13. Total: 90:30 = 90.50 hours (minutes ÷ 60).
  14. Workweek Sep 27, 2026 – Oct 3, 2026: 45:15 (45.25 h) worked.
  15. Weekly rule: regular hours above 40:00 in the workweek → 5:15 (5.25 h) at 1.5×.
  16. Overtime (1.5×): 5:15 (5.25 h) × 1.5× × $22.00/hr = $173.25.
  17. Workweek Oct 4, 2026 – Oct 10, 2026: 45:15 (45.25 h) worked.
  18. Weekly rule: regular hours above 40:00 in the workweek → 5:15 (5.25 h) at 1.5×.
  19. Overtime (1.5×): 5:15 (5.25 h) × 1.5× × $22.00/hr = $173.25.
  20. Gross pay: $1,760.00 regular + $346.50 overtime = $2,106.50.

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.
