Overview

Amazon provides a suite of tools designed to help sellers estimate, track, and review the various fees associated with selling on its platform. Understanding these tools is essential for maintaining healthy profit margins and making informed pricing decisions. This guide walks through each available tool and how sellers can use them effectively.

Key Points / What Sellers Need to Know

• Revenue Calculator - Amazon's revenue calculator lets you compare fees and estimated profit across fulfillment channels, helping you decide between FBA and merchant-fulfilled options for each product.
• Fee Preview Report - This downloadable report shows estimated selling and fulfillment fees for all your current listings, giving you a comprehensive snapshot of your fee obligations.
• Estimated Fee Per Unit - This tool breaks down the core fees charged when a specific SKU sells, including referral fees and FBA fees, so you can evaluate unit-level economics.
• Referral Fee Preview Report - A dedicated report that calculates referral fees based on your current listed prices, available for download through Seller Central reports.
• SKU Economics Tools - Both a real-time card view and a detailed historical report help you track per-product profitability over time at the parent-ASIN, child-ASIN, mSKU, or FNSKU level.
• Monthly Storage Fee Report - Shows estimated storage costs for each ASIN stored in Amazon fulfillment centers, critical for managing inventory carrying costs.

Fee Estimation Tools

Amazon offers several forward-looking tools that help sellers anticipate costs before and during active selling. The Revenue Calculator is the most commonly used, allowing sellers to input product details and compare what they would pay under FBA versus fulfilling orders themselves. The Fee Preview Report extends this by covering your entire catalog at once, making it especially useful during periodic pricing reviews. For developers and sellers with large catalogs, the My Fees Estimate API provides programmatic access to fee calculations, accepting a list of products and returning the applicable selling and fulfillment fees. These estimation tools are best used when evaluating new products, adjusting prices, or deciding on fulfillment strategies.
