Frequently Asked Questions

How much does Amazon take per Sale?

Amazon typically charges a referral fee (usually 15%), plus FBA fulfillment fees if you use Fulfillment by Amazon. Additional costs may include storage, ads, and returns.

What is a good Amazon Profit Margin?

Most private label sellers aim for a 20–30% net profit margin after all fees and advertising costs. However, acceptable margins vary by category and competition.

What is Break-Even ACOS?

Break-even ACOS (Advertising Cost of Sale) is the maximum percentage of revenue you can spend on ads before your profit becomes zero. It helps sellers control ad efficiency.

How Do Etsy Fees Work?

Etsy charges a transaction fee (6.5%), payment processing fees (typically 3% + $0.25), and optional offsite advertising fees. Sellers should calculate total fees before listing products.

Does Shipping Affect Profit Calculations?

Yes. Both inbound shipping (Amazon) and shipping costs (Etsy or FBM) directly reduce net profit and should always be included in pricing models.
