Cartonization Calculator
Find the smallest box that fits your order items and calculate void fill percentage. Reduce shipping costs and packaging waste with right-sized cartons.
Calculate the total cost of processing a return including shipping, receiving, inspection, and restock or disposal. Understand your reverse logistics cost.
Product returns are an inevitable cost of business, especially in ecommerce where return rates range from 15-30%. Each return triggers a chain of costs: return shipping, warehouse receiving and inspection, quality determination, and either restocking for resale or disposal for unsalvageable items. Understanding the total cost per return is essential for setting return policies, pricing, and profitability analysis.
This calculator sums the four major return cost components รขโฌโ shipping, receiving/inspection, restocking, and disposal รขโฌโ to produce a fully loaded cost per return. For items that are restocked, the disposal cost is zero; for items that are disposed or liquidated, the restocking cost is zero but you also lose the product value.
Use This calculator to quantify the true impact of returns on profitability, evaluate whether free return shipping is sustainable, and identify which cost components offer the most improvement opportunity.
Use the result to compare operating scenarios, pressure-test assumptions, and rerun the model when volumes, rates, or service targets change.
Many businesses know their return rate but not their return cost. This calculator reveals the full financial impact of each return, helping you make informed decisions about return policies, product quality improvements, and processing efficiency. At 20% return rate, a $15 return cost per item can erode 3% or more of total revenue.
Restockable Return Cost = Shipping + Receiving + Restocking
Disposal Return Cost = Shipping + Receiving + Disposal
Weighted Avg Cost = (Restock % รโ Restockable Cost) + (Disposal % รโ Disposal Cost)Result: $12.05 weighted average cost per return
Restockable cost = $6.50 + $3.00 + $4.00 = $13.50. Disposal cost = $6.50 + $3.00 + $2.00 = $11.50. Weighted = (70% รโ $13.50) + (30% รโ $11.50) = $9.45 + $3.45 = $12.90 per return. At 1,000 returns/month, that's $12,900 monthly.
Beyond direct processing costs, returns create hidden costs: lost revenue during the return period, reduced margin when items are marked down for resale, customer service labor for return inquiries, and negative environmental impact from reverse logistics transportation.
Investing $1 in returns prevention (better product information, quality control, fit tools) typically saves $3-$5 in return processing costs. The most effective ecommerce operations focus on reducing return rates rather than just processing returns efficiently.
Returns management systems automate return authorization, provide customers with prepaid labels, route items to the nearest processing center, and guide warehouse staff through inspection and grading workflows. Investing in returns technology can cut processing time by 30-50% and improve restock rates.

The average ecommerce return costs $10-$20 to process including shipping, handling, and restocking. Complex or heavy items can cost $25-$50+. The exact cost depends on your return shipping rates, labor costs, and product characteristics.
For apparel and consumer goods, 50-80% of returns are restockable. Electronics have lower restock rates (40-60%) due to opened packaging and testing requirements. Food and personal care items are rarely restockable.
Free returns increase conversion rates but add $5-$10 per return. Analyze whether the additional sales justify the return shipping cost. Some brands offer free returns for exchanges only or charge for returns on sale items.
When the return processing cost exceeds the item's value, some companies tell customers to keep the item and still issue a refund. This saves the return shipping and processing cost. It is common for items under $15-$20.
Improve product descriptions and photos, add size guides and fit tools, include video demonstrations, use customer reviews, and improve quality control. Better pre-purchase information is the most effective return reducer.
Disposed items may be liquidated to off-price retailers (recovering 10-30% of value), donated for tax benefit, recycled for materials, or sent to landfill. A robust disposition strategy recovers maximum value from unsalvageable returns.
