Overtime With Multiple Pay Rates

When you work at two or more hourly rates in the same week, your overtime rate isn't based on either rate alone — it's calculated from a weighted average. Here's exactly how that works.

Why Overtime Gets Confusing With Multiple Pay Rates

If you work one job at one hourly rate, overtime is straightforward: hours beyond 40 in a workweek are paid at 1.5 times your rate. But many workers earn different rates within the same week — a "travel rate" versus a "work rate," a standard warehouse rate versus a forklift-certified rate, or weekday pay versus a weekend premium. When that happens, the overtime rate on your paycheck often doesn't match either of your hourly rates, and it's not obvious where the number came from.

This is one of the most common sources of paycheck confusion, and understanding the underlying rule makes it much easier to verify your employer's math.

The Legal Rule: Weighted Average Overtime

Under federal law (the Fair Labor Standards Act), when a non-exempt employee works at two or more different hourly rates within the same workweek, the employer calculates overtime using a weighted average of all rates — sometimes called the "blended rate" method.

Think of it like a weighted GPA: hours worked at each rate count proportionally toward your average rate for the week. More hours at the lower rate pulls the average down; more hours at the higher rate pushes it up. Your overtime premium is then based on this blended figure.

This is the standard method required under the FLSA. An alternate method exists — paying 1.5x whichever rate applies to the hours actually worked as overtime — but it requires a valid prior agreement between employer and employee and is less commonly used.

Step-by-Step Calculation

Let's walk through a concrete example. A worker has two rates in one week:

  • Rate A: $18/hour — worked 30 hours
  • Rate B: $25/hour — worked 18 hours
  • Total hours: 48 (which means 8 hours of overtime, since 48 − 40 = 8)

Step 1 — Total straight-time earnings

Calculate what you'd earn if every hour were paid at its respective straight-time rate — no overtime premium yet:

(30 × $18) + (18 × $25) = $540 + $450 = $990

Step 2 — Weighted average rate

Divide total straight-time earnings by total hours worked:

$990 ÷ 48 hours = $20.63/hour

Step 3 — Overtime premium

Your employer already paid you straight-time for all 48 hours in Step 1. The overtime premium is the extra "half" owed on top for each overtime hour:

0.5 × $20.63 × 8 overtime hours = $82.50

Step 4 — Total pay for the week

$990 (straight-time for all hours) + $82.50 (OT premium) = $1,072.50

What Counts Toward Your Regular Rate (and What Doesn't)

The "regular rate" used in the weighted average calculation must include most forms of compensation for hours worked, but a few categories are handled differently:

  • Shift differentials and weekend/holiday premiums — if your employer pays an extra amount for working a specific shift or day (e.g., a $3/hour night-shift differential), that premium is generally included in the regular rate calculation. It's not excluded just because it's called a "premium" rather than a "rate."
  • Non-discretionary bonuses (promised in advance, tied to performance, attendance, or production) must generally be included in the regular rate.
  • Discretionary bonuses (not promised in advance, entirely at the employer's discretion) are excluded from the regular rate.

The FLSA has a specific list of payments that can be excluded from the regular rate, including certain benefit plan contributions and expense reimbursements. For edge cases not covered here, the Department of Labor's FLSA regular rate guidance is the authoritative source.

A Note on Low "Travel Pay" Rates

A question that comes up frequently: what happens when your employer pays a significantly lower rate for travel time than for on-site work, and that lower rate pulls down your blended overtime rate?

Compensable travel time — time that must legally be paid under federal or state law — does factor into the weighted average calculation. The rate at which travel time is paid can meaningfully affect your overtime premium, particularly if you work substantial travel hours in a week.

Whether a particular travel rate is permissible depends on multiple factors, including federal and state minimum wage requirements, the nature of the travel, any applicable employment agreements, and how the travel time is classified. This is a genuinely complex area of wage and hour law that varies by jurisdiction and by the specifics of the arrangement.

If your travel rate seems unusually low compared to your work rate, or if you're unsure whether your employer is calculating your blended overtime correctly, it's worth asking your employer's HR or payroll department how the calculation works. You can also contact your state's labor department or consult an employment attorney for guidance specific to your situation.
