Amazon FBA Profit Calculation Framework
Use this structure to avoid optimistic profit estimates when fees, ads, and returns start changing at scale.
Step-by-step model
Apply one consistent order-level structure so your pricing and campaign decisions are comparable.
Net Profit = Price - Product Cost - Shipping - Commission - Ad Cost - Other Costs
- Start from final selling price per order
- Subtract landed product cost and shipping fulfillment
- Allocate commission, ad spend, and reserve costs
