How Overtime Pay Is Estimated

Formula

Regular pay + (hourly rate x overtime multiplier x overtime hours) = weekly gross pay

Example

$25 x 40 regular hours + ($25 x 1.5 x 5 overtime hours) = $1,187.50 weekly gross pay.

Important limits

  • The default multiplier is 1.5x, often called time and a half.
  • Actual overtime eligibility depends on job duties, pay basis, state rules, and employer policy.
  • This calculator estimates gross pay before tax withholding and benefit deductions.

Data Sources and Review Process
