Marketplace Fee Calculator

Selling on online marketplaces involves various fees that can significantly impact your profit margins. This calculator helps you understand exactly how much you'll pay in fees and what your actual take-home profit will be when selling on Amazon, eBay, Etsy, or Shopify.

Why accurate fee calculation matters: Each marketplace has a different fee structure — from Amazon's category-based referral fees to eBay's final value fees, Etsy's transaction and listing fees, and Shopify's plan-based payment processing rates. Without proper calculation, sellers often underestimate their costs and overestimate their profits.

This tool gives you a clear picture of all applicable fees, your net profit, profit margin, and ROI — helping you make informed pricing decisions and choose the best marketplace for your products.

Frequently Asked Questions

How accurate are the fee rates?

The fee rates are based on the latest published fee schedules from each marketplace (updated for 2025–2026). Amazon referral fees reflect tiered pricing introduced in 2024. eBay rates include the February 2025 fee increase. Etsy and Shopify rates reflect current published rates.

Important note: Marketplaces may change their fees at any time, so always verify with the official fee schedule for the most current rates.

Why does Amazon have tiered categories like "Clothing (≤$15)" and "Clothing (>$20)"?

Amazon uses price-based tiered referral fees for certain categories. For example, Clothing items are charged different rates based on selling price:

$15 or below: 5% referral fee
$15–$20: 10% referral fee
Over $20: 17% referral fee

Select the tier that matches your product's selling price for accurate results.

What is the $1.80 closing fee for Amazon media items?

Amazon charges an additional $1.80 per-item closing fee on all media categories including:

Books
Music & DVD
Video Games
Software

This fee is charged on top of the referral fee and applies to both FBA and FBM (Fulfilled by Merchant) sellers.

Why is eBay's per-order fee $0.40 instead of $0.30?

As of February 2025, eBay charges:

Orders ≤ $10

$0.30 per order

Lower fee for small transactions

Orders > $10

$0.40 per order

Standard fee (calculator default)

Since most eBay transactions exceed $10, the calculator defaults to $0.40. You can adjust this in Fee Settings if needed.

What happened to the "Shopify Plan"?

Shopify renamed their mid-tier plan from "Shopify" to "Grow". The calculator reflects this change with the current plan names:

Basic — Entry-level plan
Grow — Mid-tier plan (formerly "Shopify")
Advanced — Advanced features
Plus — Enterprise solution

Why do Shopify payment rates change when I select a different plan?

Shopify Payments processing rates vary by plan. When you select a plan, the calculator automatically adjusts the payment processing rate:

Plan	Processing Rate	Fixed Fee
Basic	2.9%	$0.30
Grow	2.7%	$0.30
Advanced	2.5%	$0.30
Plus	2.15%	$0.30

How is ROI calculated?

ROI (Return on Investment) is calculated using this formula:

ROI Formula: Net Profit ÷ (Product Cost + Shipping Cost) × 100

It shows the percentage return on your total investment in acquiring and shipping the product. A positive ROI indicates profit, while a negative ROI indicates a loss.

Can I account for Etsy's Offsite Ads fee?

Yes. Etsy charges an Offsite Ads fee on sales generated from offsite advertising clicks:

15% — Standard rate for most shops
12% — Reduced rate for shops over $10K annual revenue

Enter this fee in the "Offsite Ads Fee" field under Fee Settings. The default is $0 since this fee only applies to specific sales driven by Etsy's advertising.

Note: Only include this fee if your sale came from an Etsy offsite ad click. Not all sales incur this charge.
