About this calculator
The Fair Labor Standards Act (FLSA) requires non-exempt employees be paid at least 1.5× their regular rate for hours worked over 40 per week. Some states impose additional daily overtime (California triggers OT after 8 hr/day and double time after 12 hr/day). "Time-and-a-half" refers to the 1.5× multiplier; "double time" is 2× and is usually contractual (union agreements, holidays, 7th consecutive day worked) rather than federally required.
Total weekly gross = regular_rate × regular_hours + regular_rate × multiplier × OT_hours. The regular rate must include most non-discretionary bonuses and shift differentials, not just base pay — a common wage-theft claim is employers computing OT off base rate only when a shift differential should have raised the regular rate. Exempt employees (typically salaried professionals earning above ~$1128/week in 2025) are not entitled to overtime under FLSA.
How to use
Example — $20/hr, 40 regular + 8 OT at 1.5×. Regular pay = 20 × 40 = $800. OT pay = 20 × 1.5 × 8 = $240. Total = $1 040 gross for the week. Example — same hours at double time. OT pay = 20 × 2 × 8 = $320. Total = $1 120. Double time is $80 more per week for this schedule, worth about $4 160 over a full year if it were every week.
Frequently asked questions
Is time-and-a-half required by law?
For non-exempt employees under the FLSA, yes — federal law requires 1.5× the regular rate for hours over 40 in a week. Exempt employees (typically salaried managers, professionals, or outside sales) are not covered. Some states like California, Alaska, and Nevada have stricter daily overtime rules.
What counts as the "regular rate"?
The regular rate includes hourly base pay plus non-discretionary bonuses, shift differentials, and commissions, prorated over the week. It does not include discretionary bonuses or expense reimbursements. Computing OT off base rate only when other components apply is a common wage-and-hour violation.
When is double time (2×) required?
Federal FLSA does not require double time. California requires 2× after 12 hr/day and on the 7th consecutive workday. Many union contracts specify 2× on Sundays, holidays, or after 8/10 hr in a day. Otherwise 2× is at employer discretion.
How is overtime taxed?
Overtime is taxed as ordinary wage income — same rate as regular pay. Some paychecks appear more heavily taxed because the "flat supplemental" 22% federal withholding rate applies to lump-sum bonuses; regular overtime is withheld at your normal W-4 rate. The tax total reconciles at year-end.
