Is it profitable to sell on Amazon? Everything you need to know before starting

Returns and other hidden costs

• Returns: Amazon has a very buyer-friendly return policy. The seller assumes the processing cost in many cases.
• Refunds and claims: they can negatively impact the seller’s account if they are not managed correctly.
• Product preparation costs: labeling, specific packaging for FBA, etc.
• VAT and tax management: if you sell in multiple European marketplaces, you need to manage VAT in each country.

Factors that determine if your business will be profitable on Amazon

Profitability on Amazon does not depend on a single factor. It is the result of the sum of all these elements:

The gross margin of the product

This is the most critical factor. If your product has a gross margin below 40-50%, it will be very difficult to survive on Amazon after commissions, logistics, and advertising. The rule of thumb: you need at least a 30% net margin for the business to be viable in the long term.

The competition in your category

Highly competitive categories (electronics, fashion accessories) have tighter margins and a greater need for advertising investment. Specialized niches or products with a differentiated value proposition allow for higher margins with less ad spend.

The estimated sales volume

Amazon penalizes products with low turnover (long-term storage costs). A product that sells little can generate losses even if the unit margin is good. The BSR (Best Seller Rank) of your category is a good indicator of standard sales volume.

Your capacity to manage stock

Running out of stock on Amazon is very costly: you lose organic ranking, sales history is interrupted, and recovering visibility requires more advertising investment. Good inventory management is just as important as the marketing strategy itself.

Advantages and disadvantages of selling on Amazon

Advantages of selling on Amazon

• Immediate access to millions of buyers in Spain and Europe without the need to have your own website.
• High conversion rate thanks to the trust that the platform generates among consumers.
• Outsourced logistics with FBA: Amazon manages storage, shipping, and returns.
• Possibility of rapid internationalization towards other European marketplaces (Germany, France, Italy, United Kingdom).
• Specialized integrated advertising software (Sponsored Products, Sponsored Brands, Sponsored Display) with real-time performance data.
• Simple registration process and without a mandatory minimum investment.

Disadvantages of selling on Amazon

• High commissions: between 6% and 17% per sale, plus logistics and advertising costs.
• Low brand visibility: Amazon prioritizes the product over the seller. Building brand awareness is more difficult.
• Platform dependency: Amazon can change its policies, suspend accounts, or enter to compete in your category with Amazon Basics.
• Amazon’s access to your sales data, which it can use to develop its own products that compete directly with you.
• Generous returns for the buyer: the seller assumes most of the cost and the reputational risk.
• The algorithm penalizes non-rotating inventory, which increases storage costs.

Individual Plan vs Professional Plan: which one suits you?

Amazon offers two selling methods in Seller Central:

Conclusion: If your goal is to build a real business on Amazon, the Professional Plan is the only viable option. The Individual Plan only makes sense for testing the market with very few references.

When does it make sense to sell on Amazon with an agency?

Many brands start managing Amazon internally. It works up to a certain point. But there comes a time when the platform’s complexity exceeds the internal team’s capacity, and every euro poorly invested in advertising or every inventory management error has a real cost.

Signs that you can no longer manage it alone

• Sales have stagnated and you don’t know why.
• Advertising spend is going up but the return (ROAS) is going down.
• Your account receives warnings or has been suspended.
• You don’t have time to optimize listings or analyze data.
• You want to expand to other European markets but don’t know how.

What an agency specialized in Amazon does

An agency like AMZtribe comprehensively manages your presence in the marketplace: from product listing optimization and Amazon SEO strategy, to PPC advertising campaign management, metrics analysis, and international expansion.

The goal is not just to sell more. It is to sell better: with a higher margin, less long-term advertising dependency, and a stronger brand within the marketplace.

How to calculate your product’s profitability on Amazon step by step

Basic net margin formula

To know if your product is profitable on Amazon, apply this formula:

In this example, the net margin is 36.7%, which would be viable. Below a 15-20% net margin, the business starts to become risky in the face of any variation in costs or price drops by the competition.
