Open Overtime Pay CalculatorReal workplace situation
A swapped Saturday, an extra coverage shift, or a traded weekday can move someone over the weekly threshold even when both employees thought they were only trading shifts.
Original schedule: 40 hours. Added Saturday swap: 6 paid hours. Removed Wednesday shift: 4 paid hours. Final week: 42 paid hours, so expected overtime above 40 is 2 hours.
Working rule
Overtime hours = final approved qualifying weekly hours - overtime threshold.

Notes from real use
A schedule swap can affect both employees differently.
If the swapped shift has weekend or night differential, calculate that premium separately.
If the workweek boundary splits the swap, place each shift in the correct week.
Mistakes that change the result
Do not calculate overtime from the original schedule.
Do not forget unpaid lunch on the swapped shift.
Do not apply overtime to all hours when only the excess hours qualify.
