How do you calculate deburr cost per batch?

Multiply parts per batch by cost per part, scale by the fill ratio, then add the fixed setup cost. With 100 parts at $45, 80% fill and $250 fixed, that is 100 x 45 x 0.80 + 250 = $3,850 total, or $38.50 per piece.

Why is my per-piece deburr cost so high on small batches?

The $250 fixed setup and media charge is spread across fewer parts. At 100 parts it adds $2.50/part; at 25 parts the same fixed cost adds $10/part, so undersized loads inflate per-piece cost fast.

What is a good per-part deburring cost?

For small steel and aluminum parts in vibratory or centrifugal finishing, $0.50 to $5 per part is common. A $38.50 figure like the worked example signals either high-value parts, heavy manual touch-up, or a badly underfilled bowl.

How does bowl fill ratio affect cost?

Fill ratio scales the variable cost in this model. Running a bowl at 80% versus 50% improves throughput per kilowatt-hour and per media-wear cycle, lowering the effective cost you capture per batch.

Deburr in-house vs outsource — how do I compare?

Compute your true per-piece batch cost here ($38.50 in the example) and compare it to the finisher's quoted piece price plus freight and lead-time risk. Include your fixed media and labor, which buyers often forget.

Should I include media and compound in the fixed cost?

Yes. Media top-off and compound dosing recur every batch regardless of part count, so they belong in the fixed cost field, not the per-part rate.

Mass Finishing, Deburring & Polishing calculator

Deburr Cost Per Batch Calculator

Deburr Cost Per Batch tells you what a single tumble or vibratory load actually costs once you fold in the variable per-part labor, the share of the bowl you actually filled, and the fixed setup and media charges that hit every run. Finishing supervisors and estimators use it to quote outsourced deburr work, decide minimum batch sizes, and spot when a half-full bowl is quietly doubling per-piece cost. On a real shop floor the fixed cost is the killer: media top-off, compound dosing, and load/unload labor land whether you run 30 parts or 300. Getting this number right is the difference between a profitable deburr cell and one that loses money on small jobs.

What this calculator does

Calculate deburr cost per batch for mass finishing, deburring & polishing planning, quoting, troubleshooting, capacity review, or process improvement.
Use it when deburr cost per batch in mass finishing, deburring and polishing is being put through a mass finishing, deburring and polishing weighted-cost review.
It computes the total cost of one deburring batch (variable cost scaled by fill ratio plus fixed setup) and the resulting cost per finished part.

Formula used

Deburr Cost Per Batch cost = quantity × rate × capture factor + fixed cost
Per-unit deburr cost per batch = total cost ÷ quantity

Inputs explained

Parts deburred per batch:
Deburr cost per part:
Batch utilization (bowl fill ratio):
Fixed setup and media cost per batch:

How to use the result

Use it when quoting a deburr job, setting a minimum economic batch size, or comparing in-house tumbling against an outside finisher.
It treats the fill ratio as a flat multiplier on variable cost and does not model cycle-time changes, media wear curves, or parts that need a second pass for burr-free edges.

Current U.S. benchmarks

As of May 2026, U.S. manufacturing runs at 75.6% of capacity (Federal Reserve via FRED), up 0.2 points from a year earlier. Enter your own plant's utilization; the national figure is a reference point for how loaded the industry is.
