Overtime Pay Calculator
Calculate your total pay including overtime.
Enter hourly rate, regular hours, overtime hours, and OT multiplier to see your total earnings.
Overtime pay calculations follow federal or regional labor law rules that require employees to be compensated at a premium rate for hours worked beyond the standard threshold. In the United States, the Fair Labor Standards Act (FLSA) sets the federal minimum at 1.5× the regular rate for hours over 40 per week.
Regular hourly rate: Regular Rate = Annual Salary ÷ (52 × 40) (for salaried workers) Or simply the stated hourly wage for hourly workers.
Overtime rate: Overtime Rate = Regular Rate × 1.5 (federal minimum; some states require 2×)
Weekly pay formula: Weekly Pay = (Regular Hours × Regular Rate) + (Overtime Hours × Overtime Rate)
Where:
- Regular Hours — hours up to the standard threshold (typically 40/week)
- Overtime Hours — hours exceeding 40/week
- 1.5× (“time and a half”) — the FLSA-mandated federal minimum premium
- 2× (“double time”) — required in California for hours over 12 in a day, and all hours on the 7th consecutive day of work
What each variable means:
- Blended rate — total earnings divided by total hours; useful for comparing different work arrangements
- Exempt vs. non-exempt — salaried employees earning over $684/week (2024 federal threshold) are often exempt from FLSA overtime; check state law as thresholds vary
- Comp time — public sector employers may offer compensatory time off instead of pay; private employers generally cannot
Reference: overtime rules by jurisdiction:
- Federal (FLSA): 1.5× after 40 hours/week
- California: 1.5× after 8 hours/day or 40 hours/week; 2× after 12 hours/day
- Nevada: 1.5× after 8 hours/day or 40 hours/week
- Alaska: 1.5× after 8 hours/day
Worked example: Hourly rate: $22/hour. Hours worked this week: 48 hours (40 regular + 8 overtime). Federal rules apply.
- Regular pay = 40 × $22 = $880
- Overtime rate = $22 × 1.5 = $33/hour
- Overtime pay = 8 × $33 = $264
- Weekly total = $880 + $264 = $1,144
Annual equivalent if this schedule continues: $1,144 × 52 = $59,488 vs. $45,760 at straight-time 40 hours — an extra $13,728/year.
