Return Rate & Reverse Logistics Formulas

1. Unit Return Rate (%)
Return Rate (%) = (Units Returned / Total Units Sold) × 100

The percentage of fulfilled customer orders returned for refund or exchange.

2. Order Retention Rate (%)
Retention Rate (%) = 100% - Return Rate (%)

Percentage of orders that remain successfully kept by customers.

3. Net Retained Revenue
Net Retained Revenue = (Total Units Sold - Units Returned) × Average Price

True top-line revenue after refund deductions.

4. Total Return Drag (Financial Loss)
Total Loss = (Units Returned × Average Price) + (Units Returned × Cost to Process)

Comprehensive financial impact including refunded top-line revenue plus return label shipping, restocking, and inspection labor.

Worked Example: Footwear Brand Reverse Logistics

A boutique sneaker store sells 800 pairs of shoes at $75.00 each. 48 pairs are returned by customers due to sizing. Return label postage and warehouse restocking cost $14.00 per return.

Input Values
Total Pairs Sold:
800 pairs
Pairs Returned:
48 pairs
Average Retail Price:
$75.00
Reverse Processing Cost:
$14.00/pair
Calculated Output
Unit Return Rate:
6.0%
Pairs Retained:
752 pairs (94.0%)
Net Retained Revenue:
$56400.00
Reverse Logistics Cost:
$672.00
Total Return Financial Loss:
$4272.00
Breakdown: The return rate is (48 / 800) × 100 = 6.0%. Net retained revenue is 752 pairs × $75.00 = $56400.00. The refunded sales amount to $3,600.00, and reverse processing adds $672.00, for an aggregate return loss of $4272.00.

Frequently Asked Questions

How is the return rate calculated?
Return Rate (%) = (Units Returned / Total Units Sold) × 100. For example, if you sell 500 units and 35 are returned, your return rate is (35 / 500) × 100 = 7.0%.
What is the average return rate in e-commerce?
While standard e-commerce return rates average 10% to 20%, apparel and footwear frequently experience return rates between 25% and 35%. Electronics and consumer goods typically hover around 8% to 12%.
What is included in the cost of a return?
A return costs far more than lost revenue. It includes outbound shipping, return label cost, warehouse inspection and restocking labor, repacking materials, and potential inventory write-off if the item cannot be resold as new.
Why does the tool prevent units returned from exceeding units sold?
You cannot return more physical items than were originally purchased. If returns exceed total sales, the input is logically invalid.
