Understanding Blended Overtime Rate
In many employment situations, especially those involving hourly wages, employees are entitled to overtime pay for hours worked beyond a standard workweek (often 40 hours). The standard overtime rate is typically 1.5 times the regular hourly rate (time-and-a-half). However, for employees with multiple regular pay rates, calculating overtime can become more complex. This is where the concept of a "blended" overtime rate comes into play.
Why a Blended Rate?
When an employee earns different regular hourly rates for different tasks or hours, simply multiplying each overtime hour by its "corresponding" regular rate might not accurately reflect the overall overtime compensation or might lead to discrepancies. A blended overtime rate aims to provide a single, consistent overtime rate that fairly represents the average overtime pay across all regular rates.
How it Works
The calculation involves determining the total earnings at regular rates for the hours worked at each rate, and then using these totals to prorate the overtime premium. Essentially, we find out how much "extra" you should earn for overtime based on your overall earning potential.
The formula generally involves:
- Calculating the total regular pay for all hours worked at each distinct regular rate.
- Calculating the total regular pay across all rates.
- Determining the weighted average regular rate based on hours worked at each rate.
- Applying the overtime multiplier to this weighted average to find the blended overtime rate.
Our calculator simplifies this process by taking your different regular rates, the hours you worked at those rates, the overtime multipliers for each rate, and the total overtime hours you are claiming. It then computes the blended overtime rate you should receive.
Example Calculation
Let's say an employee worked the following:
- Rate 1: $15/hour for 20 regular hours. Overtime multiplier: 1.5.
- Rate 2: $20/hour for 20 regular hours. Overtime multiplier: 1.5.
- Total Overtime Hours: 10 hours.
Calculation Steps:
- Regular Pay from Rate 1: $15/hour * 20 hours = $300
- Regular Pay from Rate 2: $20/hour * 20 hours = $400
- Total Regular Pay: $300 + $400 = $700
- Total Regular Hours: 20 hours + 20 hours = 40 hours
- Weighted Average Regular Rate: $700 / 40 hours = $17.50/hour
- Blended Overtime Rate: $17.50/hour * 1.5 = $26.25/hour
So, for these 10 overtime hours, the employee should be paid at a rate of $26.25 per hour.
Note: This calculator assumes a consistent overtime multiplier for simplicity in a single blended rate. If multipliers vary significantly and are applied differently per hour, a more complex calculation might be needed. Always consult your employer's policies or a labor law professional for specific situations.

// A common approach is to use the *highest* applicable multiplier, or an average if specified.

// we'll inform them and suggest using the one most relevant or an average if that's the policy.

// For this example, we'll pick one and add a note. A more robust solution might involve averaging weighted by hours.
// Let's use the higher multiplier if they are different, or prompt for clarification.
// For this calculator, we'll use a single multiplier to show *a* blended rate.
// A common simplified approach is to use a single multiplier for the blended rate calculation.
// For this calculator, we'll average the multipliers and inform the user, as it's a common simplification.
