To calculate overtime for hourly workers under the Fair Labor Standards Act (FLSA), pay 1.5 times the regular hourly rate for all hours worked over 40 in a single workweek: Overtime Pay = Overtime Hours * (Regular Rate * 1.5). For workers with multiple wage rates, calculate the weighted average blended rate across total hours worked.

Launch Overtime Pay Calculator →The Standard FLSA Time-and-a-Half Calculation
The United States Department of Labor enforces the Fair Labor Standards Act (FLSA), requiring covered employers to compensate non-exempt employees for hours worked beyond 40 per workweek at a rate not less than one and one-half times their regular rate of pay.
The Core Standard Formulas:
1.Regular Pay = Straight Hours (up to 40) * Base Rate
2.Overtime Rate = Base Rate * 1.5
3.Overtime Pay = Hours Worked Over 40 * Overtime Rate
4.Total Gross Pay = Regular Pay + Overtime Pay
The Weighted Average (Blended) Overtime Rate Formula
When an employee works at two or more different pay rates in a single workweek (for instance, 30 hours as a line cook at $18.00/hr and 15 hours as a shift manager at $24.00/hr), you cannot simply choose the lower rate or the rate in effect when overtime occurred. Under 29 CFR § 778.115, employers must compute the weighted average regular rate:
The FLSA Blended Rate Steps:
1.Total Straight Earnings = (Rate A * Hours A) + (Rate B * Hours B)
2.Regular Rate of Pay = Total Straight Earnings / Total Hours Worked
3.Overtime Premium Due = Overtime Hours * (Regular Rate of Pay * 0.5)
4.Total Gross Pay = Total Straight Earnings + Overtime Premium Due
Worked Real-World Scenarios with Exact Numbers
Scenario A: Standard 48-Hour Workweek at $24.00/Hour
A non-exempt manufacturing technician works 48 hours in a standard Monday-through-Sunday workweek at an agreed base wage of $24.00 per hour.
- Step 1 (Regular Hours): 40 regular hours × $24.00 = $960.00 straight-time pay.
- Step 2 (Overtime Rate): $24.00 × 1.5 = $36.00 overtime hourly rate.
- Step 3 (Overtime Earnings): 8 overtime hours × $36.00 = $288.00 overtime pay.
- Step 4 (Total Gross Compensation): $960.00 + $288.00 = $1,248.00 gross pay.
Scenario B: Warehouse Associate with Dual Pay Rates (Blended Overtime)
An employee works 30 hours in general warehouse inventory at $20.00/hr and 15 hours operating specialized forklift machinery at $26.00/hr, totaling 45 hours in the workweek.
- Step 1 (Straight-Time Earnings): (30 hrs × $20.00) + (15 hrs × $26.00) = $600.00 + $390.00 = $990.00 total straight pay.
- Step 2 (Blended Regular Rate): $990.00 ÷ 45 total hours = $22.00/hour regular rate.
- Step 3 (Half-Time Premium Calculation): Because straight-time pay was already accounted for all 45 hours in Step 1, the overtime hours only require an additional 0.5 premium: 5 overtime hours × ($22.00 × 0.5) = 5 × $11.00 = $55.00 overtime premium.
- Step 4 (Total Gross Compensation): $990.00 + $55.00 = $1,045.00 total gross earnings.
4 Critical Payroll Overtime Audit Pitfalls
- 1. The 80-Hour Bi-Weekly Averaging Trap: Employers frequently attempt to offset 46 hours in Week 1 against 34 hours in Week 2, paying 80 straight hours. Under the FLSA, every workweek stands alone; 6 hours of overtime must be paid for Week 1.
- 2. Omitting Non-Discretionary Bonuses: If an hourly worker earns an extra $100 attendance bonus, that $100 must be divided by total hours worked and added to the regular rate before calculating overtime. Failing to recalculate regular rate is the #1 Department of Labor wage audit violation.
- 3. California Daily Overtime Compliance: While federal law only mandates weekly overtime past 40 hours, California Labor Code § 510 mandates overtime after 8 hours in a single workday, and double-time (2.0x) after 12 hours in a single day or past 8 hours on the 7th consecutive day. Test these state variances in our Overtime Pay Calculator.
- 4. Salary Misclassification: Paying an employee on a ‘salary’ basis does not automatically exempt them from overtime. Employees must meet specific administrative, professional, or executive duties tests and exceed the federal salary threshold ($58,656 annually).
Overtime Rates & Multipliers Reference Table
| Overtime Tier | Multiplier | Statutory Condition | Example ($20 Base) |
|---|---|---|---|
| Standard FLSA Overtime | 1.5× Base | Hours worked beyond 40 in a 7-day workweek | $30.00 / hour |
| California Daily Overtime | 1.5× Base | Hours worked beyond 8 up to 12 in a single workday | $30.00 / hour |
| California Double-Time | 2.0× Base | Hours worked beyond 12 in a single workday | $40.00 / hour |
| 7th Consecutive Workday (CA) | 1.5× first 8 hrs / 2.0× after 8 hrs | Working 7 consecutive days in a single workweek | $30.00 / $40.00 |
| Federal Holiday Pay | 1.0× to 2.5× | Discretionary by employer contract (FLSA does not mandate) | $20.00 – $50.00 |
Action Plan: 5 Steps to Run Accurate Hourly Payroll
- Establish a Fixed 7-Day Workweek: Define an unalterable workweek schedule (e.g. Sunday 12:00 AM to Saturday 11:59 PM) and never shift workweeks to mask overtime.
- Track Total Productive Hours: Record all time spent on mandatory work tasks, including mandatory pre-shift briefings and equipment setup.
- Determine the Regular Rate of Pay: Aggregate hourly wages plus non-discretionary production, safety, or attendance bonuses.
- Apply 1.5x Multiplier to Hours Above 40: Multiply the isolated overtime hours by 1.5 times the established regular rate.
- Run Automated Audits: Use our free Overtime Pay Calculator to audit timesheets before dispatching payroll via Gusto, ADP, or QuickBooks.
Frequently Asked Questions (FAQ)
How do you calculate overtime for hourly employees under federal law?
Under the federal Fair Labor Standards Act (FLSA), calculate overtime by multiplying all hours worked beyond 40 in a single 7-day workweek by 1.5 times the employee’s regular hourly rate. For example, 48 hours at $20.00/hr equals 40 hours at $20.00 ($800) plus 8 hours at $30.00 ($240), totaling $1,040 gross pay.
Can an employer average hours over a two-week pay period to avoid overtime?
No. Federal law strictly evaluates overtime on a standalone 7-consecutive-day workweek basis. If an employee works 50 hours in Week 1 and 30 hours in Week 2 (80 hours total across a bi-weekly paycheck), the employer must pay 10 hours of overtime for Week 1.
How do you calculate blended overtime when an employee has two different pay rates?
Use the FLSA weighted average method: Divide the total straight-time earnings from both jobs by the total hours worked to find the regular rate of pay. Then, multiply the overtime hours by 0.5 times that regular rate and add it to total straight-time earnings.
Are non-discretionary bonuses included in overtime calculations?
Yes. Non-discretionary performance, attendance, and production bonuses must be factored into the employee’s regular rate of pay before computing overtime. Discretionary gifts (like unannounced holiday bonuses) are exempt.
