This guide to calculating costs and profit margins in Amazon FBA aims to help you make the most out of this logistics solution offered by Amazon.

I’m Jordi Ordóñez, and in this article, I’ll explain how Amazon FBA works, what the fees are, the storage costs, and other factors that will influence your profit margin.

What is Amazon FBA and how does it work?

Before diving into the details of cost calculation, it’s important to understand what Amazon FBA is. Amazon FBA is a service that allows sellers to store their products in Amazon's distribution centers. When a customer makes a purchase, Amazon handles the entire logistical process, from storage to shipping, customer service, and returns management. This makes the selling process much easier, but it also involves additional costs that you need to consider when calculating your margins.

Main cost components in Amazon FBA

The first step in calculating your profit margins in Amazon FBA is to understand all the costs involved. Below, we break down the main costs you need to consider.

1. Storage costs

One of the main costs in Amazon FBA is storing your products in Amazon's logistics centers. Amazon charges based on the space your products occupy in their warehouses, and this cost varies depending on the size and volume of your products.

• Standard storage fees: If your products are small and light, the storage fees will be lower. These fees are calculated based on volume, meaning the space your inventory takes up in Amazon’s warehouses.
• Long-term storage fees: Amazon also charges higher fees for products that have been in their warehouses for more than six months. If your products don’t sell quickly, you may face additional fees for long-term storage.

2. Shipping and handling fees

Amazon FBA also charges for the shipping and handling of your products. This cost refers to the fee you pay every time Amazon ships one of your products to a customer. The fees vary depending on the weight and dimensions of the product. Additionally, if you offer international shipping, you should consider the extra costs associated with international logistics.

3. Sales fees

Each time you sell a product through Amazon, the platform charges a commission on the sale. This fee varies depending on the product category and the type of seller account you have (individual or professional). Fees typically range from 6% to 45% of the product's sale price, depending on the category.

How to calculate profit margins in Amazon FBA

Once you understand the involved costs, the next step is to calculate your profit margin. The profit margin is the difference between the sale price and the costs associated with selling a product.

Formula for calculating profit margin

The profit margin is calculated using the following formula:

Profit Margin=(Sale Price−Total CostsSale Price)*100

Where:

• Sale Price is the price at which you sell the product on Amazon.
• Total Costs include all the costs associated with the product, such as acquisition cost, storage costs, shipping and handling fees, and Amazon's sales fees.

For example, if you sell a product for €50 and the total costs are €30, the calculation would be:

Profit Margin=(50- 3050)*100=40%

This is your profit margin. The higher the margin, the more profitable your business will be.

How to calculate ROI in Amazon FBA

ROI (Return on Investment) is another key metric to evaluate the profitability of your business. ROI tells you how much profit you’ve made relative to what you’ve invested. The formula to calculate ROI is:

ROI=(Net ProfitTotal Investment)*100

Where:

• Net Profit is the profit you’ve made after subtracting all costs.
• Total Investment is the total amount you’ve invested in the product, including acquisition cost, storage fees, Amazon fees, and other expenses.

If you bought a product for €20, sold it for €50, and your total costs were €30, your net profit would be €20. If the total investment was €20, the ROI calculation would be:

ROI=(2020)*100=100%

This is a simple example, but it shows how ROI reflects the profitability of your investment.

Tools and calculators for calculating costs and profit margins

To simplify the process of calculating your costs and profit margins, Amazon offers several useful tools, such as the Amazon FBA Calculator. This calculator allows you to calculate the costs associated with your products, including storage fees, shipping, and sales commissions, making it easier to get an accurate estimate of your profit margin.

In addition to the official Amazon calculator, there are other online tools like the Amazon FBA Calculator Spain and the Amazon Profit Calculator, which help you calculate not only the costs but also the profits you can earn from each sale. These tools are particularly useful if you sell in international markets or if you manage a diverse inventory.
