Essential Payroll Calculators

Whether you're an employee trying to understand your pay, an employer calculating wages, or an HR professional managing payroll, our specialized payroll calculators provide all the tools you need. This collection of four dedicated calculators covers every aspect of payroll calculation, from basic overtime to complex salary conversions.

🧮 Four Essential Calculators

Time and a Half Calculator

The cornerstone of overtime calculation, our Time and a Half Calculator helps you determine exactly how much you'll earn for those extra hours. Under federal law, non-exempt employees must receive overtime pay of at least 1.5 times their regular rate for hours worked over 40 in a workweek.

💡 How Time and a Half Works

Example Calculation:

  • • Regular rate: $20/hour
  • • Overtime rate: $30/hour (1.5x)
  • • Regular hours: 40
  • • Overtime hours: 10

Weekly Pay:

Regular: $800 + Overtime: $300 = $1,100

Overtime Calculator with Double Time

For complex overtime scenarios involving both time and a half (1.5x) and double time (2x) rates, our advanced Overtime Calculator handles it all. This is particularly useful for industries with holiday pay, long shifts, or union contracts that specify premium rates.

⚡ Complex Overtime Scenarios

When Double Time Applies:

  • Holidays: Christmas, New Year's Day, etc.
  • Long shifts: Over 12 hours in some states
  • Seventh consecutive day: In certain states
  • Union contracts: Specified premium rates

Example Calculation:

$25/hr base rate:

• Regular: 40 hrs × $25 = $1,000

• Overtime: 10 hrs × $37.50 = $375

• Double time: 4 hrs × $50 = $200

Total: $1,575
