How to Calculate Time and a Half

Time and a half means your overtime rate is 1.5× your regular hourly rate. It's the most common overtime pay rate in the US, Australia, Canada, and most employment contracts.

Formula: Time-and-a-Half Pay = Hourly Rate × 1.5 × Overtime Hours

Example: If you earn $20/hour and work 8 overtime hours: $20 × 1.5 = $30/hour overtime rate $30 × 8 = $240 overtime pay
