Payroll Compliance: Federal FLSA Weekly Overtime Rules

Under the United States Fair Labor Standards Act (FLSA), overtime is calculated on a fixed 7-day workweek basis rather than averaging across two-week pay periods.

Daily vs. Weekly Overtime Rules

  • Federal Standard: Overtime applies strictly when total hours worked exceed 40.0 hours in a 7-day workweek.
  • State Specific Rules (e.g. California, Nevada, Alaska): Employers must also pay 1.5x daily overtime for any hours worked beyond 8.0 hours in a single workday, and 2.0x double-time for hours beyond 12.0 hours in a workday.

How to Use This Calculator

Enter your Monday Hours (e.g. 8.5), Tuesday Hours (e.g. 8.5), Wednesday Hours (e.g. 8.5), Thursday Hours (e.g. 8.5), Friday Hours (e.g. 8.0), Saturday & Sunday Weekend Hours (e.g. 0.0), Base Hourly Pay Rate ( / hour) (e.g. 30.00), and Weekly Overtime Threshold (Standard 40 Hours) (e.g. 40.0).

Worked Example

For example, working Monday through Thursday 8.5 hours each and Friday 8.0 hours at a 30.00/hour wage: \ and . Regular pay is \ and overtime pay is resulting in a Total Gross Paycheck of 1,290.00/week.

Understanding Your Result

Time conversion reference: 1 year = 365.25 days (accounting for leap years) = 8,766 hours = 525,960 minutes. A "month" varies 28–31 days — use exact date math for legal or contractual calculations rather than assuming 30 days/month. For project management: a work-year is typically 260 days (52 weeks × 5 days). Effective time estimates should include buffer — the Planning Fallacy (Kahneman) shows people underestimate task duration by 25–50% on average.

💡 Financial Planning: Expert Principles & Risk Awareness

  • All calculations assume fixed rates and idealized conditions. Real-world results vary due to market volatility, inflation, fees, and taxes.
  • The Consumer Financial Protection Bureau (CFPB) recommends consulting a certified financial planner (CFP) for decisions involving significant sums.
  • Run at least three scenarios: optimistic, pessimistic, and most-likely — to understand the full range of potential outcomes before committing.
  • Inflation averages 2–3% annually in the US (Federal Reserve target). Long-term projections that ignore inflation significantly overstate future purchasing power.
  • Tax treatment varies widely by account type (IRA, 401k, brokerage), jurisdiction, and income level. Verify tax implications with a CPA before acting.
  • Compound interest works for you in savings/investments and against you in debt. The difference of even 1% in rate, sustained over decades, is enormous.
  • Emergency funds (3–6 months of expenses) should be established before optimizing for returns — financial security precedes financial growth.
  • Financial projections older than 12 months should be recalculated. Interest rates, tax brackets, and market conditions shift materially year to year.

❓ Frequently Asked Questions

How do you calculate total work hours for a timesheet?
Sum all decimal hours worked for each day of the workweek (Monday through Sunday). Any hours beyond 40 are multiplied by 1.5 times your base wage.

How do you convert 8 hours and 15 minutes for payroll?
Divide the 15 minutes by 60 to get 0.25 decimal hours: 8 hours and 15 minutes = 8.25 decimal hours.

Can an employer average hours over two weeks to avoid overtime?
No. Under federal FLSA law, each 7-day workweek stands alone. An employer cannot average 50 hours in week 1 with 30 hours in week 2 (80 total hours); the employee is legally entitled to 10 hours of overtime in week 1.

What is the overtime rate for $20 an hour?
The overtime rate (time-and-a-half) for a $20.00/hr wage is $30.00 per hour.

Do holiday or sick hours count toward the 40-hour overtime threshold?
Under federal law, only actual physical hours worked count toward the 40-hour overtime threshold. Unworked paid holiday, vacation, or sick hours are excluded.
