Marketplace Fee Comparison

This tool runs the same sale through each marketplace's verified fee calculator — eBay, Etsy, and Mercari — then ranks them by net profit. Each platform charges different combinations of listing fees, transaction fees, and payment processing fees. The tool subtracts all applicable fees and your item cost to show what you actually keep on each platform.

Amazon and Shopify use fundamentally different fee models (referral categories, subscription tiers, FBA) that aren't directly comparable in a single table — see their dedicated calculators for those. All math runs locally in your browser.

Amazon and Shopify use different fee models (referral fees, subscriptions, FBA) that don't fit a simple side-by-side comparison. See the Amazon Referral Fee Calculator for Amazon-specific estimates.

The live comparison composes the verified eBay, Etsy, and Mercari fee calculators on the same inputs so you can see estimated net side by side.

Each marketplace has promotions, category edge cases, and fees outside these models. Use the comparison for planning, then confirm on the official seller fee pages before listing.

Amazon referral fees have a dedicated calculator. The comparison tool focuses on the eBay / Etsy / Mercari set that shares the same comparison compose path.
