Biweekly pay means you receive a paycheck every two weeks — 26 pay periods per year. Under US federal law (FLSA), overtime is calculated on a per-workweek basis, not per pay period. This means even on a biweekly payroll, overtime is triggered at 40 hours in any single workweek, not 80 hours over two weeks.
If your employer pays you every two weeks, you might assume overtime kicks in after 80 hours in the pay period. That assumption is wrong — and it could cost you money. This guide explains exactly how overtime works with biweekly pay, with formulas and real examples.
Biweekly Pay vs Weekly Pay: The Key Difference
Biweekly payroll is simply a payment schedule — you receive your check every two weeks instead of every week. It doesn't change how overtime is calculated. Under the Fair Labor Standards Act (FLSA), overtime is always determined by the individual workweek.
| Pay Schedule | Pay Periods/Year | Overtime Threshold | Calculation Window |
|---|---|---|---|
| Weekly | 52 | 40 hrs/week | Each 7-day workweek |
| Biweekly | 26 | 40 hrs/week | Each 7-day workweek (NOT per period) |
| Semi-monthly | 24 | Varies by state | Depends on employer policy |
| Monthly | 12 | Varies | Employer-defined |
Critical point: Your employer cannot average hours across two weeks to avoid overtime. If you work 50 hours in week 1 and 30 hours in week 2, you are owed 10 overtime hours for week 1 — even though the two-week total is only 80 hours.
The Biweekly Overtime Pay Formula
Since biweekly payroll contains two workweeks, calculate overtime separately for each week, then add them together.
Step 2 — Total biweekly paycheck: Total = (Regular Pay Week 1 + OT Pay Week 1) + (Regular Pay Week 2 + OT Pay Week 2)
Example 1: Overtime in One Week Only
Hourly rate: $22/hr | Week 1: 48 hours | Week 2: 36 hours
Week 1 calculation:
Regular: 40 × $22 = $880
Overtime: 8 × $22 × 1.5 = $264
Week 1 total: $1,144
Week 2 calculation:
Regular: 36 × $22 = $792 (no overtime)
Without overtime protection: 84 hrs × $22 = $1,848 — you'd be shortchanged $88.
Example 2: Overtime in Both Weeks
Hourly rate: $18/hr | Week 1: 45 hours | Week 2: 43 hours
Week 1: (40 × $18) + (5 × $18 × 1.5) = $720 + $135 = $855
Week 2: (40 × $18) + (3 × $18 × 1.5) = $720 + $81 = $801
Total overtime earned: $135 + $81 = $216
Converting Hourly to Biweekly Salary
If you want to know your expected biweekly gross pay at a standard 40 hours/week with no overtime:
Example: $20/hr × 80 hrs = $1,600 biweekly
Common biweekly base pay benchmarks:
| Hourly Rate | Biweekly (80 hrs) | Annual (no OT) |
|---|---|---|
| $15/hr | $1,200 | $31,200 |
| $20/hr | $1,600 | $41,600 |
| $25/hr | $2,000 | $52,000 |
| $30/hr | $2,400 | $62,400 |
| $35/hr | $2,800 | $72,800 |

California employees have additional overtime protections beyond federal law:
- 1.5× for hours beyond 8 per day (daily overtime)
- 1.5× for hours beyond 40 per week
- 2× for hours beyond 12 per day
- 1.5× for the first 8 hours worked on the 7th consecutive day
- 2× for hours beyond 8 on the 7th consecutive day
In California, daily overtime often adds up to more than weekly overtime. Make sure your employer is using daily overtime calculations if you're in California.
Common Biweekly Payroll Mistakes
1. Averaging hours across two weeks
This is illegal under the FLSA. Employers must calculate overtime week by week. If your paycheck shows "average of 40 hours" across the two-week period, it may be incorrect.
2. Confusing biweekly with semi-monthly
Biweekly = every 2 weeks (26 pay periods/year). Semi-monthly = twice a month (24 pay periods/year). These are different schedules. Semi-monthly pay periods can span more than one workweek, which complicates overtime calculation.
3. Not tracking breaks accurately
Unpaid break time must be subtracted from your total hours. If you work 8:00 AM–5:00 PM with a 30-minute unpaid lunch, that's 8.5 hours, not 9. Over two weeks, even small errors compound.
4. Missing the 7th-day rule (California)
If you work 7 consecutive days in a workweek in California, the 7th day triggers premium pay even if you haven't hit 40 weekly hours. Many employees miss this.
How to Track Biweekly Hours Accurately
The most reliable method is a weekly timesheet, filled out daily. Here's what to record:
- Date and day of week — essential for identifying the 7th-consecutive-day rule
- Clock-in time — when work actually began
- Break start and end — or total break minutes
- Clock-out time — when work ended
- Daily total hours — for daily overtime jurisdictions
At the end of each 7-day workweek, sum the hours and calculate overtime before moving to the next week. Don't wait until the end of the two-week period.
Frequently Asked Questions
Is overtime calculated weekly or biweekly?
Under US federal law (FLSA), overtime is always calculated on a per-workweek basis — not per pay period. Even if you're paid biweekly, overtime is triggered at 40 hours in any single 7-day workweek.
Can my employer average my hours over two weeks?
No. Under the FLSA, employers cannot average hours across multiple workweeks to avoid paying overtime. Each workweek must be evaluated independently.
How many hours is overtime on a biweekly paycheck?
There is no fixed "biweekly overtime threshold." Overtime is triggered at 40 hours per week within the pay period. If you worked 45 hours in week 1 and 35 in week 2, you have 5 overtime hours (from week 1 only).
What if my workweek doesn't start on Monday?
Employers can define any day as the start of the workweek — it doesn't have to be Monday. The key is that the workweek is a fixed, regularly recurring 7-day period. Your employer should state the workweek start day in your employment contract.
How do I calculate overtime if I have a lunch break?
Subtract unpaid break time from your total time at work. For example: 7:00 AM clock-in, 5:30 PM clock-out, 30-minute unpaid lunch = 10 hours worked. The first 8 hours are regular (or 40/week); overtime starts after that.
Do biweekly pay calculations differ for salaried employees?
Most salaried workers who earn above the FLSA exemption threshold ($684/week as of 2024) are exempt from overtime. However, salaried non-exempt employees do receive overtime — calculated by dividing their weekly salary by hours worked to get the regular rate, then applying 0.5× for each overtime hour (since the straight-time rate is already included in the salary).
Summary
Biweekly pay is simply a payment schedule — it doesn't change the fundamental rule that overtime starts at 40 hours per workweek. Calculate each workweek separately, add the two weeks together, and never let your employer average hours across the two-week period.
