Overtime Pay Calculator

How overtime pay works

Overtime pay is extra compensation for hours worked beyond a standard threshold. Most workers get time-and-a-half (1.5×) for overtime, and some jurisdictions mandate double time (2×) for long days, seventh consecutive days, or public holidays.

The formula

regular_pay       = hourly_rate * regular_hours
overtime_15_pay   = hourly_rate * 1.5 * overtime_15_hours
overtime_2_pay    = hourly_rate * 2.0 * overtime_2_hours
weekly_gross      = regular_pay + overtime_15_pay + overtime_2_pay
effective_hourly  = weekly_gross / total_hours
annual_projection = weekly_gross * 52

Overtime rules by country

United States — FLSA: Non-exempt workers get 1.5× for hours over 40 per week. Some states (California, Alaska, Nevada) add daily overtime: 1.5× over 8 hours/day and 2× over 12 hours/day. Exempt (salaried managerial/professional) workers are not entitled to overtime.

United Kingdom: No statutory overtime rate exists — pay depends on your contract. Most employers pay 1.5× for weekday overtime and 2× for Sundays/bank holidays, but your written contract governs.

Australia — Modern Awards: Typical rates are 1.5× for the first 2–3 hours over standard, 2× after that, and 2.5× on Sundays. Your specific award or enterprise agreement sets the exact rules.

Canada: Federally regulated workers get 1.5× over 40 hours/week; each province has its own rules (Ontario 44 hours, BC has daily overtime over 8 hours, etc.).

Common mistakes

Confusing “gross” with “take-home” (this calculator is gross, before tax and deductions). Forgetting that overtime is calculated on regular hourly rate, not the overtime rate. Assuming salaried workers always get overtime — they usually don’t in the US unless they’re non-exempt under the FLSA salary threshold. Missing that some overtime is pyramided (daily + weekly), meaning you might qualify on both fronts.
