Biweekly Overtime Calculator

A two-week overtime calculator that does it the legal way — overtime figured for each workweek separately, never by averaging the 80-hour period.

Calculation breakdown

Why averaging is illegal

Two weeks totaling 80 hours, split two ways — the overtime owed is not the same:

MethodWeek 1Week 2Overtime owed
Per workweek (correct)46 h34 h6 hours
Averaged to 40 (wrong)80 ÷ 2 = 40/week0 hours ✗

How to use this calculator

  1. 1

    Enter your hourly rate

    Your regular per-hour wage.

  2. 2

    Enter Week 1 and Week 2 hours

    Put each workweek's total in its own box. The calculator computes overtime for each week independently.

  3. 3

    See the period total

    Each week's gross is shown, then summed — overtime is figured per week, exactly as the FLSA requires.

At $20/hour, those 6 overtime hours are $60 of premium pay per period — about $780/year if it recurs. Want to total the actual hours from clock-in/out times first? Use the biweekly timesheet calculator.

Frequently asked questions

How is overtime calculated on biweekly pay?
Per workweek, not per pay period. Evaluate each of the two weeks separately: any hours over 40 in either week are overtime. You cannot add the two weeks to 80 and pay overtime only above 80 — that underpays a worker who had one heavy week.
Can my employer average my two weeks to avoid overtime?
No. Averaging is not allowed for non-exempt employees. 46 + 34 hours owes 6 overtime hours for week one, even though the average is 40 hours.
How many hours is biweekly full time?
A full-time biweekly period is 80 hours (two 40-hour weeks). Biweekly pay produces 26 paychecks a year, and two months each year have three paydays.
How do I calculate my biweekly pay with overtime?
Compute each week's regular and overtime pay, then add the two. 80 regular hours at $22 ($1,760) plus 5 overtime hours at $33 ($165) grosses $1,925 for the period.
Does the workweek have to match my pay period?
No. Your workweek (a fixed 7-day cycle) is separate from your pay schedule. Biweekly periods conveniently contain exactly two workweeks, which keeps the overtime math clean.
