💡
Profit isn’t the only marketplace decision

Also consider demand, competition, selling speed, customer expectations, returns, fulfilment requirements and how well the product fits each marketplace.

HOW SELLERSTACK COMPARES MARKETPLACES
Revenue − Marketplace Fees − Purchase Cost − Shipping − Packaging − Other Costs = Estimated Net Profit

SellerStack then compares projected profit, margin, ROI and marketplace fee cost across the platforms you selected.

⚠️
Marketplace fees can change

Results are estimates based on the figures and fee settings entered. Category rates, advertising, promotions, VAT treatment, programme eligibility and account-specific charges may change the final result.

💡
SellerStack Insight

Use a realistic expected selling price rather than the highest listing price you can find. A comparison is only useful when the assumptions behind it are realistic.

PROFIT MATTERS

Why Marketplace Choice Can Change Your Profit

The same product can produce very different results depending on where you sell it. Marketplace charges are only part of the equation — fulfilment, advertising, payment processing and seller-specific costs can all affect what you actually keep.

💷

Compare Net Profit

📈

Compare ROI

🧠

Make Better Decisions

Compare the numbers before choosing where to list instead of assuming the lowest-fee marketplace wins.

SELLERSTACK DECISION GUIDE

The Highest Profit Isn’t Always the Best Marketplace

A marketplace may leave more money on paper but still be the weaker selling option if demand is low or the product is a poor fit for its audience.

01 Buyer Demand

Are people actively buying this type of product there?

02 Selling Speed

How quickly is your stock likely to turn into cash?

03 Competition

How many sellers are competing for the same buyer?

04 Seller Workload

Consider fulfilment, messages, returns and listing effort.

COMMON QUESTIONS

Marketplace Comparison Calculator FAQs

Which marketplace has the lowest selling fees?

That depends on the marketplace, seller type, product category and optional services you use. A marketplace with lower fees may not necessarily produce the highest overall profit if your selling price, fulfilment costs or demand differ.

Which marketplace is most profitable for UK resellers?

There is no single marketplace that is always the most profitable. SellerStack compares the figures you enter so you can see which selected platform produces the strongest estimated result for that particular product.

Should I choose the marketplace with the highest profit?

Not automatically. Profit matters, but you should also consider demand, competition, expected selling speed, returns, seller workload and how well the product fits the marketplace audience.

Why are some marketplace fees editable?

Marketplace charges can vary by category, product, programme, seller status and optional services. Editable fee settings allow you to use figures that better reflect your own selling situation.

Are the calculator results exact?

No. The results are estimates based on the information you enter. Always verify the applicable marketplace charges before making an important sourcing, pricing or listing decision.

SELLERSTACK VERDICT

Compare the Numbers. Then Choose the Marketplace.

Marketplace fees can have a meaningful impact on profit, but the cheapest platform isn’t automatically the best place to sell. Compare your expected numbers first, then balance profit with demand, competition, selling speed and the amount of work required to complete the sale.
