Formula Behind the Calculator

The calculator uses the standard formula for overtime and extended pay:

  • Overtime Pay = Hourly Rate × Overtime Multiplier × Overtime Hours
  • Holiday Pay = Hourly Rate × Holiday Multiplier × Holiday Hours
  • Weekend Pay = Hourly Rate × Weekend Multiplier × Weekend Hours
  • Net Pay = (Regular Pay + Overtime + Holiday + Weekend) – Tax

Example Calculation

  • Hourly Rate: $20/hr
  • Regular Hours: 160 (per month) → $3,200
  • Overtime: 10 hrs × 1.5× = $300
  • Holiday: 8 hrs × 2× = $320
  • Weekend: 6 hrs × 1.75× = $210
  • Gross Pay = $4,030
  • Tax (10%) = $403
  • Net Pay = $3,627
