Time-and-a-Half Is a Gross Number
DOL overtime rules describe the premium on eligible hourly wages—not your deposit. For overtime net pay after tax, IRS supplemental withholding can make a Saturday check look harshly taxed even when annual tax is unchanged. Run the extra gross through the Salary Calculator as extra income, then read W-4 withholding so you do not quit OT over timing.
FICA still hits overtime until you pass the Social Security wage base—see FICA ceiling. Extra shifts are not a side hustle with write-offs; they are W-2 hours.
- Gross OT: Base × 1.5 × hours (if eligible).
- Net OT: After the withholding method your payroll uses.
- Friction: Extra care, parking, exhaustion mistakes.
Kansas City Saturday: 1.5× vs $18 True
Morgan in Kansas City earns $22/hour. Eight OT hours gross $264. After a simplified 30% total haircut on that slice (federal supplemental-style + state + FICA in the slider), net ≈ $185. Extra childcare $38 for the Saturday block leaves $147, or about $18.40/hour—not $33. Fatigue is not in the spreadsheet; it still counts.
Compare that $18 to a quieter extra shift next month vs a card extra payment you could fund by cutting a streaming bundle instead. Put OT net in the Budget Planner as temporary, not a new lifestyle—lifestyle creep loves overtime.
Say Yes Only If True Hourly Beats the Alternative
If $18 is still the best legal hourly you can get this month, take the shift and automate the $147 with paycheck automation toward a named goal. If it is not, a rest day that prevents a $200 mistake can win. More: money hub and gross vs net.
Salaried exempt roles may not get OT at all—confirm status before you budget phantom 1.5×. Do not treat OT as guaranteed next quarter.
