E-commerce returns: the hidden cost that wrecks your margin

How much does your store really lose on each return?

Most e-commerce owners log returns as a "cancelled sale" and move on. The problem is that this customer didn't just not buy from you: they cost you money.

The real cost of a return includes:

• Outbound shipping: which you already paid or subsidized when you sent the original order
• Reverse logistics (return shipping): between $800 and $2,500 depending on distance and weight
• Customer service time: the cost of the person who handled the exchange or return
• Refurbishing or discarding the product: in many cases it comes back in a condition that can't be resold as new
• Loss of value over time: in fashion, electronics or cosmetics, a product that took 3 weeks to come back may have lost 20-30% of its value
• Unrecovered CAC: you spent on ads to acquire that customer who ended up returning — that cost doesn't come back

The total cost of a return can represent between 20% and 65% of the returned product's value. In high-return categories like fashion, that cost can completely wipe out the margin on the original sale.

What's a normal return rate by category?

Rates vary a lot by product type. Market benchmarks:

• Fashion / apparel: 20-35% returns
• Footwear: 15-25%
• Electronics: 10-15%
• Home and decor: 8-12%
• Accessories / jewelry: 5-10%
• Consumables / food: 2-5%

According to SKU Logistics, the industry average in Argentina is 10-15%. In B2C e-commerce with a strong fashion component, it can reach 30-40%.

Think about it at scale: if you have 1,000 apparel sales a month and 25% are returns, you're processing 250 returns. If each one costs you $2,000 net between logistics and refurbishing, that's $500,000 a month that doesn't show up as a cost line in your report but is there, eating your margin.

Why don't returns show up in your income statement?

Because most management systems record returns as a credit note or cancelled sale, but don't allocate the real associated cost. Your report shows you sold $10,000,000 and the cost was $5,000,000. It doesn't show that $1,500,000 of those sales were returned with additional costs of $600,000 between logistics and refurbishing.

The result is that your margin looks better than it is. The same thing happens with other hidden e-commerce costs that don't fit easily into a manual calculation.

Returns also have a direct impact on e-commerce cash flow: the money from the original sale may already have landed in your account, but the cost of the return gets taken out later — or you have to refund it. If you don't have visibility into when that cash comes in and goes out, you can't plan purchases or pay salaries with confidence.

How do you calculate the real cost of returns in your store?

The full per-return calculation is:

And the total monthly impact:

To get that number clearly, you need to record every return with all its associated costs — something few stores do manually because it takes too much time and coordination between logistics, customer service and accounting.

What strategies reduce the impact of returns on margin?

You can't eliminate returns, but you can reduce their impact:

• Improve product pages: high-quality photos, accurate size guides and product-in-use videos cut returns from unmet expectations by up to 30%
• An efficient reverse logistics process: deals with logistics providers to lower the cost per return once you have volume. Platforms like Boris Returns offer solutions built for the Argentine market
• An exchange policy instead of refunds: offering a product exchange avoids the full reverse logistics cost and keeps the customer in your store
• Segment SKUs by return rate: identify which products generate the most returns and make specific catalog or pricing decisions for them
• Fast refurbishing: the sooner you get a returned product back in stock, the smaller the loss of value

Frequently asked questions about e-commerce returns

Am I required to accept returns in Argentina?

Yes. The Consumer Protection Law (Ley 24,240) establishes that for online purchases, the consumer has 10 days to change their mind and return the product without having to give a reason. Returns are a reality of Argentine e-commerce you can't avoid — you can only manage them better to minimize the cost.

Should I offer free return shipping?

It depends on your margin and your return rate. If you have a high margin (over 50% gross) and a low return rate (under 8%), free return shipping can lift conversion more than it costs you. If your margin is tight or your return rate is high, charging the customer the logistics cost on returns reduces the loss — although it may lower initial conversion.

Do returns affect my reputation on Mercado Libre?

Yes. On Mercado Libre, a high rate of claims and returns hurts the seller's reputation, which affects your listings' ranking and visibility. It's an additional indirect cost that doesn't show up in the income statement but does affect future sales.

How do I know if a product category has an acceptable return rate?

Calculate the contribution margin per SKU including the average return cost for that category. If a product has a 45% gross margin but a 30% return rate with a cost of $2,000 per return, the real margin can be much lower. The analysis has to be done by category or by SKU, not at the store level.

Returns are a financial cost, not a logistics problem

If you're handling returns as a customer service problem, you're looking at the symptom. The real problem is financial: every return destroys margin, hits cash flow and distorts your profitability numbers.

Measure the real cost of your returns, build it into your per-SKU profitability analysis, and make catalog and pricing decisions based on that number. If you want to do it without building a single spreadsheet, Escalafy shows you your store's real profit including every cost — in real time.
