About This Calculator

The Overtime Calculator helps you see exactly how much you'll earn for those extra hours at work. Calculate your overtime pay rate, total pay per period, and annual earnings including both regular and overtime hours.

Under the Fair Labor Standards Act (FLSA), non-exempt employees must receive overtime pay of at least 1.5x their regular rate for hours worked over 40 in a workweek. Some employers offer double time or even triple time for certain situations like holidays or extended shifts.

Overtime Pay Formulas

OT Rate = Hourly Rate × Multiplier (1.5, 2, or 3)
OT Pay = OT Rate × Overtime Hours
Total Pay = Regular Pay + Overtime Pay

Standard multipliers: Time-and-a-half (1.5×), Double time (2×), Triple time (3×).

Practical Example

Hourly rate $20, 40 regular hours + 10 OT hours at 1.5×:
Regular pay = $20 × 40 = $800
OT pay = $20 × 1.5 × 10 = $300
Total weekly pay = $1,100

Pro Tips

  • Know your status: Salaried "exempt" employees don't qualify for OT
  • Weekly threshold: OT kicks in after 40 hours per week (federal)
  • State laws vary: California requires daily OT after 8 hours
  • Track carefully: Keep your own records of hours worked
  • Bonuses affect OT: Non-discretionary bonuses may increase your OT rate

Scenario Comparison: Overtime Earnings Impact

Scenario ($20/hr base)Weekly PayAnnual PayOT Earnings
40 hrs (no OT)$800$41,600$0
45 hrs (5 OT @ 1.5×)$950$49,400$7,800/yr
50 hrs (10 OT @ 1.5×)$1,100$57,200$15,600/yr
50 hrs (10 OT @ 2×)$1,200$62,400$20,800/yr

Common Mistakes to Avoid

  • Misclassifying exempt status: Employers sometimes wrongly classify workers as "exempt" to avoid OT. If you earn <$43,888/year salary, you likely qualify for OT.
  • Forgetting comp time limits: Private employers cannot substitute "comp time" for OT pay—you must receive 1.5× wages. Only government workers can receive comp time.
  • Missing daily OT rules: California, Alaska, and Nevada require OT after 8 hours/day regardless of weekly total. Know your state laws.
  • Not including all pay in base rate: Shift differentials, non-discretionary bonuses, and commissions must be included when calculating your OT rate.

Frequently Asked Questions

How is overtime pay calculated?

OT Pay = Hourly Rate × Multiplier × OT Hours. Time-and-a-half: $20 × 1.5 = $30/hour OT. 10 OT hours = $300 extra. Federal law requires 1.5× after 40 hours/week.

What is time and a half for $20 an hour?

$20 × 1.5 = $30/hour overtime rate. 10 overtime hours = $300. Double time ($20 × 2) = $40/hour. Triple time = $60/hour for holidays.

Who qualifies for overtime pay?

Non-exempt hourly workers get OT after 40 hours/week. Exempt salaried employees (salary >$43,888/year for 2024) don't qualify. Check FLSA regulations for your situation.
