How the overtime calculator works

Clear pay arithmetic for learning—not payroll files or legal advice.

Tool: Overtime calculator · Embed: Embeddable calculator · All how-we-calculate pages · Overtime questions

Purpose

Estimate gross pay for a period from hourly rate, regular hours, overtime hours, and multipliers you type. For education only—not a timesheet system or legal determination of overtime eligibility.

Core formulas

  • Regular pay = hourly rate × regular hours
  • Overtime pay = hourly rate × OT multiplier × OT hours
  • Double-time pay = hourly rate × double-time multiplier × double-time hours
  • Total pay = regular + OT + double-time
  • Effective hourly = total pay ÷ total hours (if hours > 0)

Period views

The main result is for the hours you entered (often treated as one week). Biweekly shows total × 2. Annual and monthly estimates multiply by weeks/year you enter (default 52), then monthly = annual ÷ 12. These are display conventions—not your employer’s pay calendar.

What we intentionally leave out

  • Whether you are legally entitled to overtime (exempt/nonexempt, state rules, etc.)
  • Shift differentials, bonuses, tips, benefits, or union contract tables
  • Automatic tax withholding or net pay
  • Employer rounding rules, meal break deductions, or clock-in systems
  • Advice on whether double time is required
