What does this calculator estimate?
45 hours at $20/hour with a 40-hour threshold pays $800 regular plus $150 overtime at 1.5x, for $950 total. Overtime hours = max(0, worked - threshold).
- Regular pay = min(worked, threshold) x rate; overtime = overtime hours x rate x 1.5.
- The FLSA requires 1.5x pay over 40 hours for most US workers (DOL).
- Some states add daily overtime and double-time rules.
How overtime pay works
Federal law requires 1.5× pay for hours over 40/week for non-exempt workers. Some states have daily overtime thresholds. The calculator splits hours at the threshold and applies the multiplier to the excess.
Limitations to watch for
Exempt employees (salaried, certain roles) don't qualify. Some states require daily overtime (8 hours) or double time. The tool uses one threshold — check your jurisdiction's exact rules.
How to use it in practice
Enter your actual hours and rate with your state's threshold. Use the total to verify paystubs, budget for extra shifts, or compare jobs with different overtime policies.

How this calculator works
Formula
Regular hours = min(worked, threshold). Overtime hours = max(0, worked − threshold). Pay = regular × rate + overtime × rate × multiplier (typically 1.5×).
Worked example
45 hours at $20/hr with a 40-hour threshold at 1.5×: regular $800 + overtime $150 = $950.
Assumptions to verify
- The employee is non-exempt.
- One overtime threshold applies.
- The multiplier matches the employer's policy (1.5× typical).
Frequently asked questions
How is overtime paid?
At 1.5× your base rate for hours over the threshold — usually 40/week. 5 hours at $20 × 1.5 = $150.
What is the overtime threshold?
40 hours per week under federal law; some states also require daily overtime after 8 hours.
Am I entitled to overtime?
Non-exempt hourly and salaried workers qualify; exempt employees (executive, professional, certain roles) don't.
What is double time?
2× pay, required in some states for very long shifts or seventh-day work.
How do I verify my paycheck?
Split your hours at the threshold, calculate regular and OT pay, and compare to gross.
Can my employer deny overtime?
No — for non-exempt workers, working the hours obligates pay at the overtime rate. Unauthorized OT can be disciplined but not unpaid.
What's a shift differential?
Extra pay for undesirable shifts (nights, weekends) — a different premium from overtime.
