Why Comparing Revenue Alone Across Marketplaces Can Mislead You About Which One Is Actually Profitable
Published: 2026-07-29
In short
When a brand runs multiple marketplaces — Rakuten, ZOZOTOWN, its own Shopify store — it's tempting to assume the marketplace with the highest revenue is the most profitable. But because fee rates, ad spend, and return rates differ by marketplace, comparing revenue alone can be misleading about real profitability. Return rates in particular are said to vary by marketplace, so comparing real profit requires first understanding return rates by marketplace.
Introduction: "revenue is growing, but the profit that's actually left over isn't"
It's common to hear from apparel D2C brands running multiple marketplaces: "Rakuten brings in the most revenue, so that's where we focus, but we're not really sure how profitable it actually is." That instinct makes sense. Each marketplace's admin dashboard shows you that marketplace's own revenue and order volume, but it doesn't automatically calculate "profit after fees" or "real gross margin after accounting for the cost of returns." Without a way to compare real profitability across marketplaces, it's easy to end up allocating focus based on revenue size alone.
Fee and ad-spend structures differ by marketplace
Rakuten, ZOZOTOWN, and a self-run Shopify store each have different fee structures and different roles for advertising spend. Marketplace-based storefronts typically charge listing fees and sales commissions, on top of which sellers often pay separately for in-marketplace advertising (for example, to rank higher in search). A self-run Shopify store has no listing fee, but the brand generally has to cover its own advertising spend to drive traffic. Even if two channels each show "$10,000 in revenue," the fees and ad spend behind that number can differ significantly by marketplace — so lining up revenue figures alone doesn't give you a real comparison of profitability.
Return rates can also vary by marketplace
It's sometimes said that apparel e-commerce return rates run around 20-40% industry-wide, but this isn't a figure backed by primary statistics — it's closer to an informal rule of thumb circulating in the industry. Actual return rates vary widely by seller, product category, and customer base, so it's best not to treat this number as a target or assumption for your own business. What matters more than a general benchmark is actually measuring your own return rate by marketplace and by product. Even for the same product, differences in customer base or how size information is presented across marketplaces can change how often it gets returned. Comparing return rates across marketplaces can reveal cases where a marketplace isn't as profitable as its revenue suggests, once the cost of handling returns is factored in.
"Highest revenue" doesn't always mean "marketplace to prioritize"
Once you account for fees, ad spend, and return rates across marketplaces, it's not unusual for the ranking by revenue and the ranking by real profit to flip. For example, situations like these can occur.
- The marketplace with the largest revenue has a high return rate, and once you subtract the cost of repackaging and re-inspecting returned items, its margin is actually lower than other marketplaces.
- A marketplace with smaller revenue has a low return rate and no ad spend, making its real margin the highest of all.
If you allocate staff time and inventory based on revenue size alone, you risk over-investing in a marketplace that isn't actually that profitable.
A framework for comparing real profit margins
When comparing real profitability across marketplaces, at minimum you need to subtract the following from revenue.
- Marketplace fees and listing fees: apply each marketplace's actual fee rate.
- Advertising spend: the ad spend that generated that marketplace's revenue, including both in-marketplace ads and your own acquisition advertising.
- Return-handling costs: labor for return shipping, re-inspection, and restocking, plus the loss on inventory that's no longer sellable after being returned.
Only once you subtract these from revenue and line up the resulting real profit — in dollar terms and as a margin — by marketplace, do you have something to base a prioritization decision on. Doing this comparison manually every time is a heavy lift, so in practice it makes sense to consolidate marketplace data in one place where it can be compared on an ongoing basis.
Summary: from comparing revenue to comparing real profit
| Common misconception | More accurate view |
|---|---|
| The marketplace with the highest revenue is the most profitable. | You can't know real profitability without subtracting fees, ad spend, and return costs. |
| It's fine to assume a 20-40% return rate industry-wide. | That figure has no primary-source backing — it's an industry rule of thumb, and you need to measure your own rate. |
| Looking at revenue by marketplace is enough. | Comparing marketplaces only becomes meaningful once you also factor in return rates and real profit margins. |
Comparing marketplaces not just by revenue, but alongside real profit after fees, ad spend, and return costs, is a step toward better decision-making when running multiple marketplaces.

Frequently asked questions
Q. Is the apparel e-commerce return rate really 20-40%?
It's a figure often cited in the industry, but it isn't backed by verified primary statistics. Actual rates vary widely by seller, product, and customer base, so rather than treating that number as your baseline, it's better to prioritize measuring your own return rate by marketplace and by product.
Q. How do I calculate real profit margin by marketplace?
Subtract fees, listing costs, ad spend, and return-handling costs from each marketplace's revenue. Since this data is usually scattered across admin dashboards with different formats per marketplace, consolidating it in one place before calculating makes ongoing comparison much easier.
Q. Should we pull out of a marketplace with a high return rate?
Deciding to exit based on return rate alone is premature. Even with a high return rate, a marketplace can have a higher average order value or repeat-purchase rate, and its margin can still beat other marketplaces even after subtracting return costs. It's worth evaluating return rate together with real profit margin, not in isolation.
