The one rule that decides everything: the workweek

However you are paid — weekly, biweekly, or twice a month — overtime is earned by the workweek. A workweek is 168 consecutive hours (7 days) on your employer's fixed schedule. Each week is judged on its own:

Biweekly example: you work 50 hours in week 1 and 30 hours in week 2, at $20/hour, paid biweekly.

WeekRegularOvertimePay
Week 1 (50 hrs)40 × $20 = $80010 × $30 = $300$1,100
Week 2 (30 hrs)30 × $20 = $600—$600
Biweekly paycheck (gross)$1,700

If your employer "averaged" the two weeks (80 hours, no overtime), you would be paid $1,600 — $100 short, and not legal under the FLSA.

Biweekly vs semi-monthly: why the checks differ

Budgeting trap: monthly equivalents in this calculator assume 52 identical weeks. If your overtime varies (seasonal work, rotating shifts), use your average week — and treat the annual figure as an estimate, not a promise.

Frequently asked questions

Paid biweekly — how is overtime calculated?

Per workweek, never per pay period. 50 hours one week plus 30 the next is 10 overtime hours, even though the paycheck covers both weeks. Averaging the two weeks is not allowed under the FLSA.

How much is 10 overtime hours at $20/hour?

$30 per hour (1.5 × $20), so $300 — on top of $800 regular pay for the first 40 hours, making $1,100 for that week.

Biweekly or semi-monthly — which pays more?

Neither. Both total the same over a year: biweekly splits it into 26 checks, semi-monthly into 24 larger ones. Overtime counting is identical.
