Marketplace Fee Calculator: Amazon, eBay, Etsy, Shopify

Marketplace Fee Calculator

This marketplace fee calculator shows exactly how much you pay in seller fees and what your real take-home profit is when selling on Amazon, eBay, Etsy, or Shopify. Pick a marketplace, enter your price and costs, and instantly see net profit, margin, ROI, and a fee-by-fee breakdown — so you can price products and compare platforms with confidence.

Each marketplace has its own 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. The calculator pre-loads the correct rates for the platform you choose, and every fee stays editable so the numbers match your exact situation.

Private by design: every calculation runs entirely in your browser. Your prices, costs, and profit figures are never uploaded, stored, or tracked.

How to Calculate Marketplace Fees

Choose a Marketplace

Open the Amazon, eBay, Etsy, or Shopify calculator. Each one loads its own fee structure and category list automatically, so you start with the right rates.

Enter Price and Costs

Type your Selling Price, your Product Cost (what you pay to acquire or make the item), and any Shipping Cost. Results update live as you type.

Select the Category

Pick your Product Category and the correct referral or commission rate is applied automatically. The percentage shows right next to each category name in the dropdown.

Fine-Tune Fee Settings

Open Fee Settings to adjust the referral fee, payment processing, listing fee, or other fees — useful for negotiated rates, store subscriptions, or extras like offsite ads.

Review Your Results

Read your color-coded net profit, profit margin, total fees, and ROI. The revenue breakdown bar shows how each dollar splits between cost, fees, shipping, and profit.

Every rate is editable. Categories set sensible defaults, but you can override the referral percentage, payment processing, listing fee, or other fees in Fee Settings — and the math recalculates instantly.

Frequently Asked Questions

How do I calculate net profit after marketplace fees?

Net profit is your selling price minus product cost, shipping cost, and every marketplace fee (referral or final value, payment processing, listing, and any other fees). Enter those numbers and the calculator does the subtraction live, showing the result in green for a profit or red for a loss, alongside your profit margin and ROI.

How much does eBay charge sellers?

eBay charges a final value fee on the total sale — around 13.6% for most categories, with some categories higher (Books & Media at 15.3%) or lower (Guitars & Basses at 6.7%). On top of that there is a $0.40 per-order fee. The calculator covers 18 eBay categories and lets you adjust any rate in Fee Settings.

What are Etsy fees per sale?

Etsy charges a flat 6.5% transaction fee on the sale, plus payment processing and a $0.20 listing fee per item. If a sale comes from an offsite advertising click, Etsy adds an offsite ads fee — enter that in the Offsite Ads field, which defaults to $0 since it only applies to specific sales.

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

Amazon uses price-based tiered referral fees for some categories. Clothing items at $15 or below are charged 5%, items from $15 to $20 are 10%, and items over $20 are 17%. Select the tier that matches your product's selling price so the referral fee is accurate.

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

Amazon adds a fixed $1.80 closing fee per item on media categories — Books, Music & DVD, and Video Games — on top of the referral fee. The calculator applies it automatically when you select one of these categories, and it shows as a separate line in the fee breakdown.

Why do Shopify payment rates change when I switch plans?

Shopify Payments processing rates vary by plan: Basic (2.9%), Grow (2.7%), Advanced (2.5%), and Plus (2.15%), each plus a fixed per-transaction fee. Picking a plan sets the matching rate automatically. If you use a third-party gateway instead, choose the matching "+ 3rd Party Gateway" option to include Shopify's extra transaction fee.

How is ROI calculated?

ROI (return on investment) is net profit divided by your invested cost — product cost plus shipping cost — expressed as a percentage. It shows how hard your money works, which is why a product can have a modest margin but a strong ROI when the cost of goods is low. Profit margin, by contrast, is net profit as a share of the selling price.

Which marketplace has the lowest seller fees?

It depends on your product and price. Etsy's flat 6.5% can beat eBay's ~13.6% or Amazon's 15% referral on many items, but listing fees, payment processing, and category rates all shift the math. Run the same selling price and costs through each calculator and compare the net profit and total fees side by side to see which platform actually keeps you the most.

Are the fee rates accurate?

The rates are based on each marketplace's published fee schedules, including Amazon's tiered referral pricing, eBay's per-order fee, and Etsy and Shopify's current rates. Marketplaces can change fees at any time, so the rates are starting points — always confirm against the official fee schedule, and edit any value in Fee Settings to match.
