How to Use the Amazon FBA Profit Calculator

Understanding your numbers is the difference between a thriving e-commerce business and a failing one. This Amazon FBA Profit Calculator helps you peel back the layers of Amazon's complex fee structure to find your true bottom line.

Key FBA Fee Components Explained

• Selling Price: The list price your customer sees on Amazon.com.
• Product Cost (COGS): What you pay your manufacturer per unit.
• Referral Fee: Amazon's "commission" for selling on their platform. This is usually 15% for most categories like Home, Kitchen, and Electronics, but can vary from 8% to 45%.
• Fulfillment Fee: The cost Amazon charges to pick, pack, and ship your product. This depends heavily on the weight and dimensions of your item.
• Shipping to Amazon: Your inbound freight costs from your warehouse or manufacturer to the Amazon Fulfillment Center.

Why Margin and ROI Matter

While Net Profit tells you how much money goes into your pocket, Net Margin and ROI tell you how healthy your business is. A healthy FBA business typically aims for a 25-30% margin and a 100%+ ROI. High ROI is critical because it allows you to reinvest in more inventory and scale your brand faster.

Frequently Asked Questions

1. Does this include PPC costs?

No. Pay-Per-Click advertising costs vary by keyword and campaign. You should subtract your average ACOS (Advertising Cost of Sales) from your net profit to get your "True Profit."

2. What is a "Good" FBA Margin?

Most successful sellers look for a "Rule of Thirds": 1/3 for product costs, 1/3 for Amazon fees, and 1/3 for profit.
