When does brand resale pay off? The unit economics of second-hand fashion

Brand resale pays off when an item's expected resale price, adjusted for the chance it actually sells, exceeds the full cost of getting it, processing it and shipping it. Because most of that cost is fixed per item, resale tends to work for higher priced, durable products with strong second-hand demand and struggles for low priced basics. Indirect benefits, such as new customers and trade-in credit spent on new products, can change the picture, but only if they are measured.

How big is the resale market for fashion brands?

Demand is growing. ThredUp's 2025 Resale Report, as summarised by Retail Dive, projects the US secondhand apparel market to reach $74 billion by 2029 and US online resale to nearly double to $40 billion by 2029, with 58 percent of US consumers shopping secondhand in 2024. BCG and Vestiaire Collective estimate that secondhand fashion and luxury could reach up to $360 billion globally by 2030, growing around 10 percent a year, about three times faster than firsthand. Affordability is cited by nearly 80 percent of buyers as a key reason to buy secondhand, which caps the prices resale can command.

What does it cost to resell one garment?

The cost per item is mostly independent of its price. A €40 T-shirt and a €400 coat both need to be received, inspected, cleaned, photographed, described, stored, picked and shipped. That is the core of resale economics.

The table also explains why categories differ. Outerwear, bags and footwear tend to carry higher original prices and survive wear better, so a larger part of each resale price remains after processing. Basics and lower priced items pass through the same steps with far less value at stake, and the affordability expectation of second-hand buyers limits how far their prices can rise. Brands should therefore model resale economics by category and price band rather than as one programme average.

Two levers matter most: the share of items that sell, and how fast they sell. Zalando reported in March 2026 that up to 50 percent of adult pre-owned pieces on its platform sell within 24 hours, rising to 90 percent for premium brands. Fast sell-through reduces holding costs and price markdowns; slow moving stock erodes margins quickly.

What do resale operators' financials reveal?

Listed resale companies show both the potential and the difficulty. ThredUp reported, according to FashionUnited, full year 2025 revenue of $310.8 million, up 20 percent, with 6.08 million orders and 1.65 million active buyers. Adjusted EBITDA was $13.5 million, or 4.4 percent of revenue, while the company still recorded a loss from continuing operations of $20.2 million. The company also reported that direct listings launched in late 2025 achieved average selling prices more than double those of its core marketplace.

The lesson for brands is not a target margin, because a consignment marketplace and a brand selling its own trade-in stock account for revenue differently. It is that scale, automation and higher value items are what move a resale business towards profitability, even for specialists.

Which resale models have the best economics for brands?

• Peer-to-peer on the brand site. The customer photographs, lists and ships; the brand earns a fee or credit. Low cost per item, but less control over quality.
• Trade-in for store credit. The brand handles processing but pays in credit, which is spent on new products. Costs are higher, the loop to new sales is direct.
• Resale of returns and damaged stock. Acquisition cost is already sunk, and the alternative may be outlet or disposal.
• Marketplace partnership. The partner takes processing and listing work for a commission. Lower margin per item, lower fixed cost.

BCG and Vestiaire Collective write that independently managing resale has proven challenging for brands because of liquidity, operational complexity and inventory management, which explains why many combine models rather than running everything in house.

How should brands measure resale ROI?

1. Calculate contribution per item sold by grade and category, including all processing and fulfilment costs and an allocation for unsold items.
2. Track sell-through and days to sell per grade, and the price realised as a share of original retail price.
3. Measure how much trade-in credit is redeemed and what share is spent on full price products.
4. Compare acquisition of new customers through resale with paid acquisition cost in other channels.
5. Record avoided costs where resale replaces disposal or outlet routes for returns, and the data it provides for EU unsold goods disclosures.

When should a brand not run its own resale?

If average prices are low, products wear out quickly or second-hand demand for the brand is thin, an own programme will likely lose money on every item. In that case a marketplace partnership, a peer-to-peer feature or simply making product data available to existing resale platforms may deliver most of the brand and customer benefit at a fraction of the cost. The right test is a time limited pilot in one category with full cost accounting, not a launch based on market growth figures alone.
