Overtime Pay Calculator

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 for hours past the eighth on the 7th consecutive day of work (the first eight that day are time and a half)

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 a week ($35,568 a year) are often exempt from FLSA overtime. A 2024 rule that would have raised that line was struck down by a federal court in November 2024, so $684 still stands. Several states set their own, higher thresholds.
• 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, but only for workers paid under 1.5 times the state minimum wage; 40 hours/week for everyone else
• Alaska: 1.5× after 8 hours/day or 40 hours/week, at employers with four or more staff

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 against $45,760 at straight-time 40 hours, an extra $13,728 a year.

This page stops at gross pay. In the US, the premium half of that overtime ($11 an hour here) comes off federal taxable income from 2025 through 2028, up to $12,500 a year. The overtime net pay calculator works out the take-home figure with it.

Overtime is calculated by workweek, not by pay period. A biweekly paycheck covers two separate 7-day workweeks. If you worked 50 hours one week and 30 the next, you don’t average out to 40; you’re owed 10 hours of overtime for the first week regardless. Employers occasionally try to spread hours across pay periods to dodge overtime, but that’s a Fair Labor Standards Act violation. Colorado adds a 12-hour daily threshold on top of the 40-hour weekly one, and California’s daily-OT rules trigger on individual days even if the weekly total stays below 40.
