Should available hours mean calendar hours?

Use the denominator stated in your operating plan. Calendar hours and scheduled production hours answer different questions, so keep that definition consistent.

Is this the same as OEE?

No. This is a running-time ratio. OEE also accounts for performance and quality and uses a defined planned-production-time boundary.

Can running hours exceed available hours?

No. They must cover the same mixer and period. Reconcile overtime, parallel equipment or mismatched reporting windows first.

Why does changing the target leave utilization unchanged?

Measured utilization depends only on running and available hours. The target changes the gap and additional hours required, not the recorded ratio.

Paint, Resin & Polymer Compounding calculator

Mixer Utilization Calculator

Measure mixer utilization against a consistent time window. Enter the running hours, declared available hours and your operating target for that same period.

What this calculator does

Compare measured mixer running hours with your declared available hours and utilization target.

Formula used

Mixer utilization % = running hours ÷ available hours × 100
Gap to target points = target utilization % − mixer utilization %
Nonrunning hours = available hours − running hours
Additional hours to target = max(0, available hours × target utilization % ÷ 100 − running hours)

Inputs explained

Disperser Running Time: Recorded running hours for this mixer and reporting period.
Available Mixer Time: Declared available hours for the same mixer and period.
Target Utilization: Utilization target from your operating plan.

How to use the result

Best suited to weekly mixer Review, utilization target comparison.
Does not measure mixing quality, speed loss or full equipment effectiveness. Nonrunning time is not automatically recoverable productive capacity.

Current U.S. benchmarks

As of Aug 2026, U.S. manufacturing runs at 75.7% of capacity (Federal Reserve via FRED), down 0.1 points from a year earlier. Enter your own plant's utilization; the national figure is a reference point for how loaded the industry is.
The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
The producer price index for industrial chemicals stands at 336.006 (BLS, Aug 2026), up 13.3% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,543 chemical manufacturing establishments employing about 911,245 workers (Census County Business Patterns, 2023).
