Overtime Calculator

Q: How is overtime pay calculated?

Under the FLSA, non-exempt employees earn at least 1.5x their regular rate for hours over 40 in a workweek. At $20/hour, overtime pays $30/hour — 45 hours in a week earns $800 regular + $150 overtime = $950.

Q: What is time and a half for $18 an hour?

$27 per hour (18 × 1.5). Each overtime hour at $18 base adds $27 to the paycheck.

Q: Who is eligible for overtime?

Most hourly (non-exempt) workers. Salaried employees can be exempt if they meet both a duties test and a salary threshold under federal rules. Some states add daily overtime — California, for example, requires 1.5x after 8 hours in a day and 2x after 12.

The overtime formula

Overtime rate = Regular rate × 1.5 (federal minimum for hours over 40/week)
Weekly pay = (Regular hrs × rate) + (OT hrs × rate × 1.5) + (DT hrs × rate × 2)

Worked example

$20/hour, 40 regular hours + 5 overtime hours:

Regular: 40 × 20 = $800 · Overtime: 5 × 30 = $150 → weekly total $950

Worked every week, those 5 OT hours add $7,800/yr — pre-tax.

Overtime rules worth knowing

The federal FLSA floor is 1.5× after 40 hours in a workweek for non-exempt employees — but several states go further: California adds daily overtime (1.5× after 8 hours/day, 2× after 12, plus seventh-consecutive-day rules), and Alaska, Nevada, and Colorado have daily thresholds too. "Salaried" doesn't automatically mean exempt; exemption requires specific duties plus a salary minimum. Two budgeting cautions: OT is taxed at your normal rates (withholding may look higher per check, but it settles out at filing — see the bracket math), and building a lifestyle on overtime income is fragile since it's usually the first thing cut. Compare your blended rate against salaried offers with the salary calculator, and track the hours themselves with the hours calculator.
