Direct answer
Calculate the paycheck from the final approved paid hours in that pay period, not from the original schedule. Split the week before and after the schedule change if rates, overtime, or unpaid time changed.
Best fit search phrase: "calculate paycheck after schedule change midweek". Use the calculator after you have the source record, policy wording, or pay-stub line in front of you.
Open Weekly Paycheck CalculatorReal workplace situation
A schedule change on Wednesday can make the check look wrong because the old schedule is still in your head. Payroll usually follows the approved time record, so the cleanest check is built from each paid block that actually remained.
Original week: 40 hours. Final approved week: Mon-Tue 16 hours, Wed-Fri new schedule 21 hours, unpaid appointment 2 hours. Paid total: 37 hours. At $24/hour, expected gross = $888 before taxes.
Working rule
Adjusted paycheck gross = final approved paid hours x hourly rate, plus any qualifying overtime or premium lines.

Checklist before you rely on the number
Key checks
- Write the original schedule beside the final approved schedule.
- Remove cancelled or unpaid hours before calculating gross pay.
- Add any replacement shifts that were actually approved.
- Check whether the change moves the week above or below overtime.
- Compare gross pay before comparing the net deposit.
Practical notes
If the schedule change crosses pay-period boundaries, calculate each period separately.
A midweek change can also affect benefits, PTO use, or fixed deductions on the check.
If the time card system shows approved hours, use that as the source record before using a calculator.
Mistakes that change the result
Do not estimate from the old schedule after the change is approved.
Do not subtract unpaid time twice if the time card already excludes it.
Do not use take-home deposit to find missing worked hours.
