Profit Tracker
Upload your Fee Preview report and Business Report to see profit and fee breakdown per ASIN — revenue minus Amazon fees, with optional COGS input. Uses Amazon's actual fee data, not estimates.

What the Profit Tracker Measures
The Profit Tracker combines Amazon fee data with sales data so you can see which ASINs are actually profitable after referral fees, fulfillment fees, and product costs. It is useful when Seller Central revenue looks healthy but individual SKUs may be losing money after returns, advertising, or higher fulfillment costs.
Required Reports
Use the Fee Preview report for Amazon's estimated per-unit fees and the Business Report for sessions, units ordered, and ordered product sales. Add cost of goods manually when you want SKU-level net margin. The output ranks products by margin, flags weak ASINs, and makes it easier to decide whether a problem is pricing, fees, conversion, or product cost.
Methodology and Limits
Calculations are deterministic and based on the CSV rows you upload. The tool does not replace a full accounting system because it does not automatically pull refunds, reimbursements, storage charges, or ad spend unless those values are provided. Use it as a fast SKU health check, then reconcile final profit with your accounting records and Seller Central settlements.
