How overtime pay is calculated
Total worked hours (end time minus start time, minus breaks) are split into regular hours (up to your overtime threshold) and overtime hours (anything beyond it). Overtime hours are paid at your hourly rate multiplied by the overtime multiplier — commonly 1.5× ("time and a half") — reflecting how overtime pay works in many jurisdictions.
Frequently asked questions
What overtime threshold and multiplier should I use? This varies by country, region, and sometimes by industry or union contract — in the US, federal law generally uses an 8-hour daily or 40-hour weekly threshold with 1.5× pay, but check your local labor law or employment contract for the rule that actually applies to you.
Why does the calculator handle an end time earlier than the start time? That pattern happens with overnight shifts (e.g., 10 PM to 6 AM) — the calculator adds 24 hours in that case so the shift length is calculated correctly instead of returning a negative number.
Are breaks always unpaid? Not necessarily — this calculator assumes break time is deducted from paid hours, which matches unpaid break policies; if your breaks are paid, set the break hours field to 0 instead.
