Returns Packaging Cost Calculator
Reverse logistics cost per returned item.
About this calculator
Every returned item costs money to process even before you account for the lost sale, and this calculator adds up that reverse-logistics overhead explicitly: average return shipping cost, labor for repacking (unboxing, sorting, repackaging into resalable condition) and inspection at your fully loaded hourly labor rate, and the cost of any new packaging materials needed, all summed into a processing cost per return. It then models what the return actually costs your business net of any resale value recovered — multiplying your average order value by the percentage of returns you can resell at full price, and subtracting that recovered value from the processing cost plus the original order value, since a return that can't be resold represents both the processing overhead and the full lost merchandise value.
The calculator also expresses processing cost as a percentage of average order value, which is often more useful than a flat dollar figure because it tells you how returns-heavy categories compare against each other regardless of price point, and it projects monthly and annual totals from your stated return volume. The resale percentage is the single input worth scrutinizing most carefully: it's highly category-dependent (apparel resells far more readily than opened electronics or personal-care items), and overestimating it will make your true cost of returns look much healthier than it actually is.

How to Use This Calculator
- Enter return rate (%), annual shipment volume, and average product value ($).
- Enter return processing cost per unit ($) and restocking rate (%).
- Read total annual returns cost ($) and returns cost as a percentage of revenue.
- Review the cost breakdown: packaging, labor, restocking, and damage write-offs.
- Use results to evaluate investment in returnability-optimized packaging to reduce damage in returns.

How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersAvg return shipping ($) = 8.5, Repack time (min) = 5, Inspection time (min) = 3, Labor rate ($/hr) = 18 = 8 input(s) provided
- Calculate Processing cost per returnProcessing cost per return = avgReturnShipping + totalLaborPerReturn + newPackagingCost12.4 = $12.4
- Calculate Net loss per returnNet loss per return = costPerReturn + avgOrderValue - recoveredValuePerReturn25.9 = $25.9
- Calculate Processing cost as % of AOV27.6 = 27.6
- Calculate Shipping portion8.5 = $8.5

Frequently Asked Questions
Why is netLossPerReturn larger than costPerReturn?
costPerReturn only covers processing overhead — return shipping, repack and inspection labor, and new packaging materials. netLossPerReturn adds the full average order value on top of that (since the merchandise itself is a loss whenever it isn't resold) and then subtracts recoveredValuePerReturn, the portion of that order value you get back from resaleable items. So netLossPerReturn is always processing cost plus unrecovered merchandise value, never just the processing side alone.
How exactly does the resaleable percentage affect the net loss figure?
recoveredValuePerReturn is average order value multiplied by resalePct divided by 100, and that recovered amount is subtracted directly from the combined processing-cost-plus-order-value total to get netLossPerReturn. Raising resalePct from, say, 50% to 90% on a $45 order recovers an extra $18 per return, so this single input has an outsized effect on how expensive returns look — and it's also the easiest one to overestimate.
What two labor activities are counted separately in the cost per return?
The calculator computes repackLaborCost (repack minutes converted to a fraction of an hour, times your labor rate) and inspectionLaborCost (inspection minutes times labor rate) as two separate figures, then sums them into totalLaborPerReturn before adding it to shipping and new packaging cost. Splitting them this way makes it clear whether your labor overhead comes more from careful inspection or from repackaging effort.
Why would I look at processingCostPct instead of just the dollar cost per return?
processingCostPct expresses costPerReturn as a percentage of average order value, which lets you compare how expensive returns are, proportionally, across product lines with very different price points — a $5 processing cost is a minor annoyance on a $200 order but devastating on a $15 order. The dollar figure alone doesn't show that relative burden.
