How to Calculate OT Rate Per Hour
Calculating your overtime (OT) rate per hour is essential for ensuring you are compensated fairly for work performed beyond the standard workweek. In many jurisdictions, including the United States under the Fair Labor Standards Act (FLSA), overtime pay is legally required for eligible employees who work more than 40 hours in a single workweek.
The Standard Overtime Formula
The most common overtime rate is "time and a half." This means you are paid your regular hourly wage plus an additional 50% of that wage for every hour of overtime worked.
Formula:
OT Rate Per Hour = Regular Hourly Pay × Overtime Multiplier
For standard time and a half, the multiplier is 1.5.
Step-by-Step Calculation Guide
1. Determine Your Regular Hourly Rate
If you are paid by the hour, this is simply your hourly wage. If you are salaried, you may need to divide your weekly salary by the number of hours your salary is intended to cover (often 40 hours) to find your equivalent hourly rate.
2. Identify the Multiplier
Time and a Half (1.5x): The standard for working over 40 hours in a week.
Double Time (2.0x): Often offered for holidays, Sundays, or seventh consecutive workdays in some contracts or states (like California).
Triple Time (3.0x): Rare, but sometimes applicable for working on major holidays in specific industries.
3. Apply the Math
Multiply your Regular Rate by the Multiplier.
Real-World Example
Let's say Jane earns $24.00 per hour. She worked 45 hours last week, meaning she has 5 hours of overtime at the standard "time and a half" rate.
Regular Rate: $24.00
Multiplier: 1.5
OT Rate Calculation: $24.00 × 1.5 = $36.00 per hour
To find her total overtime pay:
OT Hours Worked: 5 hours
Total OT Pay: $36.00 × 5 = $180.00
Exceptions and Variations
While the 1.5x multiplier is standard, strict rules apply regarding who is eligible (non-exempt employees) vs. who is not (exempt employees). Additionally, bonuses and commissions earned during the workweek may need to be included in the "Regular Rate" calculation before the multiplier is applied, slightly increasing the OT rate per hour.
