Direct answer
Calculate a variable-hours raise by multiplying the hourly increase by the expected hours for each week, then using a realistic range instead of one fixed paycheck number.
Best fit search phrase: "calculate pay raise if hours vary each week". Use the calculator after you have the source record, policy wording, or pay-stub line in front of you.

A $2 raise is not the same paycheck increase for a 22-hour week and a 39-hour week. A range is more honest than pretending every week looks the same.
Raise: $2/hour. Low week: 24 hours = $48 extra gross. Typical week: 34 hours = $68 extra gross. High week: 40 hours = $80 extra gross before taxes.
Working rule
Extra gross pay = hourly raise amount x paid hours in that period.

Checklist before you rely on the number
Key checks
- Find the hourly raise amount.
- Choose low, typical, and high weekly hours.
- Multiply the raise by each hours scenario.
- Check overtime separately if high weeks exceed the threshold.
- Estimate take-home after gross raise is clear.
Practical notes
Variable schedules make monthly income less predictable even after a raise.
If the raise starts mid-period, calculate only hours after the effective date at the new rate.
If overtime is common, check whether the raise changes overtime pay too.
Mistakes that change the result
Do not multiply the raise by 40 hours if you rarely work 40 hours.
Do not ignore the raise effective date.
Do not treat extra gross pay as extra take-home pay.
