Weighted Overtime Calculator

If you work at two different rates for the same employer in one week, your overtime rate is neither of them — it's a weighted average. This is the FLSA's own method, and it's the one most payroll errors get wrong.

Your week at two rates

Both jobs must be with the same employer in the same workweek.

Total pay this week$1,320.00

Straight-time pay (both jobs + bonus)$1,200.00
Weighted regular rate$24.00/hr
Overtime hours (10.0) — premium at half the weighted rate$120.00

Why only a "half" premium? Your straight-time pay already covers 1× for every hour worked, including the overtime hours. The law adds the extra 0.5× on top — at the blended rate.

The weighted-average method, step by step

  1. Add up all straight-time pay for the week at both rates (plus non-discretionary bonuses): 30 × $20 + 20 × $30 = $1,200.
  2. Divide by total hours to get the weighted regular rate: $1,200 ÷ 50 = $24/hour.
  3. Overtime premium = half the weighted rate × hours over 40: 0.5 × $24 × 10 = $120.
  4. Total pay = $1,200 + $120 = $1,320.
The classic payroll error: paying overtime at 1.5× whichever job you happened to be doing after hour 40 (or worse, at the lower rate). Unless you and your employer agreed in advance to the rate-in-effect method, the FLSA default is the weighted average — check your stub.
