Direct answer
Estimate pay from actual weekly paid hours instead of an average schedule, then separate regular hours, overtime, shift premiums, PTO, and unpaid time.

Open Gross Pay CalculatorRealistic scenario
A variable schedule makes a normal paycheck number almost useless. One week may have 31 hours, the next 44, and the next 38 with a Sunday premium. The better habit is to build each week from the time card.
Week estimate: 36 regular hours x $21 = $756 gross. Add 4 Sunday differential hours x $2 = $8 premium. Estimated gross before taxes: $764.
Calculation frame
Weekly gross = regular pay + overtime pay + premiums + paid leave lines.

How to check it
Key checks
- Enter only the paid hours for that week.
- Separate overtime before calculating gross pay.
- Add shift or weekend premium as its own line.
- Add PTO or holiday hours only if paid.
- Use the result as gross pay before taxes and deductions.
Details people usually miss
If your schedule changes every week, a monthly budget should use a conservative low-hour estimate.
If overtime varies, estimate it separately so one busy week does not make the whole month look larger than it is.
If a premium applies only to part of the shift, do not apply it to every hour.
Common mistakes
Do not use a 40-hour assumption when the schedule changes.
Do not average overtime into regular pay.
Do not forget unpaid lunch in each shift.
