How to Use the FBA Profit Calculator - Complete Guide
Our FBA Profit Calculator helps you estimate your potential profit before listing products on Amazon. Follow this step-by-step guide to get accurate calculations.
Step 1: Select Your Marketplace
Start by selecting the Amazon marketplace where you plan to sell. Different marketplaces have different fee structures:
- USA: Most comprehensive fee structure
- UK: European fee rates
- Canada: Canadian marketplace fees
- Germany: European Union rates
- India: Indian marketplace structure
- UAE: Middle East rates
The calculator automatically adjusts all fees based on your marketplace selection.
Step 2: Enter Product Information
Product Name (Optional)
Enter a name to help you identify this calculation later. This is saved with your calculation history.
Product Category
Select your product category. This is important because:
- Referral fees vary by category (8% to 20%)
- The calculator auto-fills the correct referral fee percentage
- Some categories have special fee structures
Pricing
- Selling Price: The price you'll list the product for on Amazon
- Cost Price: Your total cost per unit (manufacturing, sourcing, etc.)
- Quantity: Number of units you plan to sell
Step 3: Product Specifications
Weight
Enter the product weight. You can use pounds (lbs) or kilograms (kg). The calculator converts automatically for accurate fee calculations.
Dimensions
Enter length, width, and height. Use inches or centimeters. These determine your product size tier and fulfillment fees.
Product Type
- Standard: Most products fall into this category
- Oversize: Products exceeding standard size limits
- Special Oversize: Very large or heavy items
The calculator helps determine the correct type based on your dimensions, but you can override if needed.
Step 4: Cost Breakdown
Shipping to Amazon
Total cost to ship your inventory to Amazon fulfillment centers. Divide total shipping cost by number of units.
Packaging Cost
Cost per unit for product packaging (boxes, bubble wrap, etc.)
Labeling Cost
Cost per unit for FNSKU labels and other required labeling
Photography Cost
Cost per unit for product photography (divide total cost by units)
Step 5: Advertising Costs
Choose your advertising strategy:
- None: No advertising costs
- ACOS-based: Enter your target ACOS (Advertising Cost of Sale) percentage. The calculator estimates ad spend based on revenue.
- Fixed: Enter a fixed advertising budget per unit
