Frequently Asked Questions

Q

How is overtime pay calculated?

Overtime pay = Overtime hours × (Hourly rate × Overtime multiplier). For time-and-a-half: 10 overtime hours at $20/hr = 10 × ($20 × 1.5) = $300 overtime pay.

  • Standard formula: (Hours over 40) × (Hourly rate × 1.5) = overtime pay for the week
  • At $25/hr with 10 OT hours: 10 × $37.50 = $375 in extra overtime pay
  • Double-time (2×) applies in California after 12 hours in a single day or on the 7th consecutive workday
  • Include non-discretionary bonuses, shift differentials, and commissions when calculating the OT base rate
  • Salaried non-exempt employees must convert salary to hourly rate: annual salary ÷ 2,080 hours
Q

What is time and a half?

Time and a half means 1.5× your regular hourly rate for overtime hours. If you earn $20/hour, overtime is $30/hour. This is the federal minimum overtime rate for hours over 40/week.

  • At $15/hr, time-and-a-half is $22.50/hr — 10 OT hours adds $225 to your weekly check
  • At $25/hr, time-and-a-half is $37.50/hr — 10 OT hours adds $375 per week
  • At $35/hr, time-and-a-half is $52.50/hr — 10 OT hours adds $525 per week
  • Some employers voluntarily pay double-time (2×) for holidays or extreme hours even where not required
  • The 2024 FLSA salary threshold is $43,888/year — salaried employees below this are OT-eligible
Q

When does overtime start?

Federal law requires overtime after 40 hours/week. Some states require daily overtime after 8 hours. California requires 1.5× after 8 hours/day and 2× after 12 hours/day.

  • Federal FLSA: overtime kicks in after 40 hours in a 7-day workweek, not per day
  • California: 1.5× after 8 hrs/day, 2× after 12 hrs/day, and 2× on the 7th consecutive workday
  • Alaska, Nevada, and Colorado also have daily overtime rules — check your state labor department
  • The workweek is defined by the employer (e.g., Sunday–Saturday) and cannot change week-to-week to avoid OT
  • Comp time (time off instead of OT pay) is only legal for government employees, not private sector

Q

Is overtime taxed differently?

Overtime is not taxed at a higher rate, but it may push you into a higher tax bracket. Withholding may be higher because the payroll system projects higher annual income.

  • Overtime income is taxed at the same rate as regular income — there is no special OT tax
  • Withholding may appear higher because payroll systems annualize the larger paycheck
  • If over-withheld, the excess comes back as a tax refund when you file your annual return
  • A $375/week OT bonus ($19,500/year) may push you from the 22% to the 24% federal bracket
  • Adjust your W-4 allowances if consistent OT causes over-withholding throughout the year

Example Calculations

150-Hour Week at $25/hr (Time and a Half)

Inputs

Hourly Rate$25.00
Total Hours Worked50
Regular Hours Limit40
OT Multiplier1.5

Result

Total Weekly Pay$1,375.00
Regular Pay (40 hrs)$1,000.00
Overtime Pay (10 hrs)$375.00
Overtime Rate$37.50/hr

Regular Pay = 40 x $25 = $1,000. Overtime Rate = $25 x 1.5 = $37.50/hr. Overtime Pay = 10 x $37.50 = $375. Total = $1,000 + $375 = $1,375.

255-Hour Week at $20/hr (Time and a Half)

Inputs

Hourly Rate$20.00
Total Hours Worked55
Regular Hours Limit40
OT Multiplier1.5

Result

Total Weekly Pay$1,250.00
Regular Pay (40 hrs)$800.00
Overtime Pay (15 hrs)$450.00
Overtime Rate$30.00/hr

Regular Pay = 40 x $20 = $800. Overtime Rate = $20 x 1.5 = $30/hr. Overtime Pay = 15 x $30 = $450. Total = $800 + $450 = $1,250.

Overtime Pay Laws, Calculations, and Tax Impact

Federal and State Overtime Rules Explained

40 hours per workweek is the federal overtime threshold under the Fair Labor Standards Act (FLSA) — every hour beyond 40 must be compensated at a minimum of 1.5× the regular hourly rate. At $25/hour, that means $37.50 for each overtime hour, turning a 50-hour week from $1,000 in regular pay to $1,375 total with $375 in overtime.

California imposes the strictest daily overtime rules in the nation: 1.5× after 8 hours in a single day and 2× after 12 hours, regardless of weekly total. A California worker earning $30/hour who works a 14-hour shift earns $30 for the first 8 hours ($240), $45 for hours 9–12 ($180), and $60 for hours 13–14 ($120) — $540 for one day versus $420 at federal rules.

Alaska, Nevada, and Colorado also have daily overtime thresholds, though specifics vary. The workweek is defined by the employer (e.g., Sunday through Saturday) and cannot be changed week-to-week to avoid triggering overtime. Comp time (time off instead of OT pay) is only legal for government employees under federal law.

Who Qualifies for Overtime Pay

$43,888/year is the 2024 FLSA salary threshold — salaried employees earning below this amount are automatically eligible for overtime regardless of job duties. Above this threshold, "exempt" status depends on performing executive, administrative, professional, or outside sales duties as defined by the Department of Labor.

Common exempt roles include managers supervising 2+ employees, professionals requiring advanced degrees (lawyers, engineers), and administrative employees exercising independent judgment on significant business matters. Misclassification is one of the most frequent wage violations: workers labeled "managers" who spend 80%+ of time on non-supervisory tasks may still qualify for overtime.

Hourly workers are almost always non-exempt and entitled to overtime. To convert a salary to hourly for OT calculation: $43,888 ÷ 2,080 hours = $21.10/hour. Use the hourly to salary calculator to convert between formats and verify whether your compensation falls above or below the threshold.

Tip: If you’re salaried below $43,888 and not receiving overtime pay, you may have a wage claim. Contact your state labor department for guidance.

The Real Impact of Overtime on Annual Earnings

10 hours of weekly overtime at $25/hour adds $375/week, $19,500/year in pre-tax income — a 37.5% boost on top of the $52,000 base salary. For workers in trades, healthcare, and manufacturing where 50-hour weeks are common, overtime represents a significant portion of total compensation.

At $35/hour, consistent 10-hour overtime weeks add $27,300 annually ($52.50/hr OT rate × 10 hours × 52 weeks). At $15/hour (near minimum wage), the same schedule adds $11,700 — still substantial for hourly workers. The paycheck calculator can model exact take-home pay including OT at your specific tax rate.

Double-time situations amplify earnings further. A California worker at $30/hour working four 12-hour shifts per week earns $30 × 32 regular hours ($960) + $45 × 16 daily OT hours ($720) = $1,680/week, compared to $1,200 for 40 hours at straight time — a 40% premium for the same 48 total hours.

Hourly RateOT Rate (1.5×)10 OT Hrs/WeekAnnual OT Income
$15$22.50$225/week$11,700
$20$30.00$300/week$15,600
$25$37.50$375/week$19,500

Overtime and Taxes: Why Your OT Check Looks Smaller

$375 in weekly overtime does not mean $375 more in your bank account. Payroll systems project the higher paycheck as your ongoing rate, temporarily withholding at a higher annualized bracket. If your regular $1,000/week paycheck withholds at 22%, the $1,375 OT check may withhold at 24% on the entire amount — not just the overtime portion.

Overtime income is taxed at the exact same rates as regular income. There is no special "overtime tax" despite the persistent myth. The apparent over-withholding corrects itself when you file your annual return: if too much was withheld throughout the year, the excess comes back as a refund. Consistent OT earners should adjust W-4 allowances to minimize the refund and keep more money per paycheck.

A $19,500 annual overtime bonus at the 22% marginal bracket generates $4,290 in additional federal tax, plus $1,209 in Social Security (6.2%) and $283 in Medicare (1.45%). Net OT take-home is roughly $13,718 of the $19,500 — about 70% after all taxes. Use the income tax calculator to model your full tax picture with overtime included.

Tip: Overtime is NOT taxed at a higher rate. If your OT check seems heavily taxed, it’s over-withholding that you’ll recover as a refund. Adjust your W-4 if this happens consistently.

How to Use the Overtime Calculator

$25 hourly rate, 50 total hours, 40-hour regular limit, and 1.5× multiplier produces $1,000 regular pay + $375 overtime pay = $1,375 total weekly pay. The calculator instantly shows the overtime rate ($37.50/hr), overtime hours (10), and the complete weekly earnings breakdown.

Change the multiplier to 2.0 to model double-time scenarios in states like California. Adjust the regular hours limit from 40 to 8 for daily overtime calculations. Run multiple scenarios to compare the financial impact of accepting overtime versus declining it.

Tip: Enter your typical weekly hours to see projected annual overtime income, then use the paycheck calculator to see the after-tax impact.

  1. 1

    Enter your hourly rate

    Use your base pay rate before any overtime premium. Check your pay stub if unsure — it’s listed as "regular rate."

  2. 2

    Enter total hours worked

    Include all hours for the workweek. Common values: 45, 50, 55, or 60 for heavy overtime weeks.

  3. 3

    Set the regular hours limit

    Use 40 for federal/most states. Use 8 for California daily OT calculations per shift.

  4. 4

    Choose the overtime multiplier

    Select 1.5 for standard time-and-a-half, or 2.0 for double-time in applicable jurisdictions.
