What belongs in the cost per returned unit?

Inbound freight, inspection and disposition labor, refurbishment or write-off, and any customer credit above the recovered value. Keep cycle counting and fixed systems cost in the containment pool.

Why must the allocation share stay at or below 100 percent?

A product cannot absorb more than the whole return program. When several products share the program, their charged shares must total no more than 100 percent.

Does a bigger return batch lower the cost per unit?

Yes, because the fixed containment and warranty pool spreads over more returned units. The variable cost per unit does not move with the batch size.

When is prevention cheaper than paying the returns?

When the cost per returned unit sits above your target and the cause repeats. A packaging or hardware fix that removes the defect costs less than the return it prevents.

Damage Return Cost Calculator

Cost the damage returns for a product from the returned units, a per-unit return cost, the share charged to this product and fixed containment. The page measures the cost per returned unit against your target.

What this calculator does

Total, variable and fixed damage return cost, the cost per returned unit, and the gap to target.

Formula used

Variable return cost = units × cost per returned unit × allocation ÷ 100
Total damage return cost = variable return cost + fixed containment
Damage return cost per unit = total cost ÷ returned units
Cost vs target per unit = target cost per returned unit − damage return cost per unit

Inputs explained

Returned or Damaged Units: Units returned or damaged in the period.
Cost per Returned Unit: Freight, inspection, refurbishment or write-off per unit.
Return Cost Allocation: Share of the return cost charged to this product.
Fixed Containment or Warranty Cost: One-time containment or warranty reserve for the batch.
Target Cost per Returned Unit: Cost per returned unit the product must stay under.

How to use the result

Best suited to quantifying a return spike, setting a warranty reserve, justifying a packaging change.
Prevention spending and resale value recovered from repaired units are excluded. Freight rates and salvage credits need their own per-unit adjustments.

Current U.S. benchmarks

The producer price index for lumber stands at 286.633 (BLS, Aug 2026), up 7.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
