Key Overtime Formulas & Direct Snapshot
Standard Gross Pay Formula: Gross Pay = (Regular Hours × Base Rate) + (Overtime Hours × Base Rate × 1.5) + (Double Time Hours × Base Rate × 2.0) + Bonuses/Differentials.
Example: 40.0 regular hours + 5.5 overtime hours @ $25.00/hr = (40 × $25.00) + (5.5 × $37.50) = $1,000.00 + $206.25 = $1,206.25 Gross Pay.

📖 Comprehensive Guide to Gross Pay & Decimal Overtime Calculations

Accurately calculating gross payroll requires converting standard base-60 clock times into base-10 decimal hours. Because payroll engines like ADP, QuickBooks, Paychex, and Workday perform standard decimal multiplication, multiplying clock minutes directly against an hourly wage leads to severe payroll underpayments or overpayments.

The 4 Essential Payroll Overtime Formulas

1. Decimal Conversion: Decimal Hours = Hours + (Minutes ÷ 60)
2. Standard Overtime: OT Earnings = OT Hours × (Base Rate × 1.5)
3. Double Time: DT Earnings = DT Hours × (Base Rate × 2.0)
4. FLSA Blended Rate: Regular Rate of Pay (RRP) = Total Straight Earnings ÷ Total Hours Worked

Federal vs State Overtime Laws

Under the federal Fair Labor Standards Act (FLSA) (29 U.S.C. § 207), covered non-exempt employees must receive overtime pay for hours worked over 40 in a workweek at a rate not less than time-and-one-half their regular rates of pay. There is no federal limit on the number of hours an employee may work in any workday.

However, state laws provide stricter protections that employers must follow:

  • California (Labor Code § 510): Requires 1.5x pay after 8 hours in a workday and 40 hours in a workweek; 2.0x double time for all hours worked beyond 12 hours in any workday, and after 8 hours on the 7th consecutive day of work.
  • Colorado (COMPS Order #39): Requires 1.5x overtime for hours worked over 40 per workweek, over 12 hours per workday, or over 12 consecutive hours without regard to the start/end of the workday.
  • Alaska: Requires 1.5x overtime for hours worked over 8 hours per day or over 40 hours per week for employers with 4 or more employees.

❓ Frequently Asked Questions (FAQ)

For 45.5 hours at a $20.00/hour base wage: Straight-time Regular Pay = 40.0 hours × $20.00 = $800.00. Overtime Pay = 5.5 hours × ($20.00 × 1.5 = $30.00) = $165.00. Total Gross Pay = $800.00 + $165.00 = $965.00.
When an employee works two or more different jobs at different pay rates in a single workweek, the FLSA requires calculating the weighted average regular rate: Total Straight-Time Earnings divided by Total Hours Worked. Overtime is then paid at 0.5 times this weighted regular rate for all hours worked over 40.
Under California Labor Code § 510, non-exempt employees must receive 1.5x pay for hours worked over 8 up to 12 hours in a workday, and 2.0x double time for hours worked beyond 12 in a single day, as well as 1.5x for the first 8 hours on the 7th consecutive day and 2.0x thereafter.
Yes. Divide the minute portion by 60: 45 minutes ÷ 60 = 0.75. So 42 hours and 45 minutes equals 42.75 decimal hours (40.0 regular hours + 2.75 overtime hours).
