Now let’s dive into what the Amazon profit calculations are and based on the different fees.

What is the Amazon Profit Margin Calculator?

While you may think this is a specific calculator that Amazon provides, it’s not – It’s a basic formula for calculating your profit margin at the product level.

Here is the calculation:

Subtract all costs associated with the sale of your product and the corresponding Amazon Fees from your sales price to get your profit, then divide by the sales price and multiply by 100%.

This will give you a percentage that represents your profitability, and the higher percentage the better, of course.

The set of costs that you add together to calculate the net profit of your products considering the following Amazon fees:

Referral Fees

This is a percentage of the sale price that Amazon charges for each item sold and the referral fee is based on the category of the item being sold and can range from 7% to 45% of the sale price. The total sales price is the total amount paid by the buyer, including the item price and any delivery or gift-wrapping charges.

FBA fulfilment fees

FBA fees cover storing, picking, packing, and shipping the item. The fulfilment fees are based on the package size and weight of the products being sold. To access the FBA fees, please refer to the Google sheet file that has been shared with you. The tabs with the fees are initially hidden, but you can unhide them by clicking on the three horizontal lines and selecting the tab name you wish to view. Once you click on it, the tab will appear alongside the other unhidden tabs.

Monthly storage fees

Inventory Storage Fees are charged between the 7th and 15th day of the month following the month the fee applies, and it’s calculated based on cubic feet of each product.

Tips for improving your profit margin on Amazon

So, you’ve used our calculations and you have your percentage back, it’s pretty low how can you get this a little higher so you get more ££ profit for your products? Well, here are some tips:

1. Packaging efficiencies: Look at ways to optimize product packaging to minimize dimensions and weight while maintaining product protection. Custom-sized boxes and eliminating unnecessary packaging materials can reduce FBA fees. Additionally, sellers can check their product eligibility for the FBA Small and Light as their products may qualify for reduced FBA fees.

2. Verify FBA product measurements: You can request Amazon to remeasure and reweigh items if sellers suspect incorrect dimensions or weight. Correct measurements can lead to decreased FBA fees and potential reimbursements for overcharged fees.

3. Offer packs and bundles: Increase the average order value by bundling products together! Selling them as a bundle incurs only one FBA fee, compared to separate listings with separate FBA fees.

4. Optimize TACOS: Continuously refine and optimize Amazon advertising campaigns to maximize ROI and reduce advertising costs.

These are some strategies that can help increase the profit margin quickly! Some long-term solutions include pricing optimization, supplier negotiations, supply chain and operational efficiency improvements.
