Amazon FBA Profit Calculator: Shopify & Etsy Fees Compared

Take the selling price and subtract the product cost, freight to Amazon, packaging, the referral fee, the FBA fulfillment fee, monthly storage, your selling plan, ad spend and expected returns. What is left is your net profit per unit.

Usually 15% of the price as a referral fee, plus the FBA fee if Amazon ships the order. For a typical 1 to 2 lb product priced at $20 to $30, total Amazon fees are often 30 to 40% of the price.

A $0.20 listing fee, a 6.5% transaction fee on the item price plus shipping, and 3% + $0.25 payment processing in the US. Offsite Ads add 15% (or 12% for larger shops) on orders that come from those ads.

Shopify fees per order are lower because there is no referral fee, but you pay a monthly plan and must bring all of your own traffic. Once you add ad costs, the gap is often smaller than it looks.

Many sellers aim for 20% or more net margin after all fees and ads. Under 10% leaves little room for price drops, returns or higher ad costs.

Amazon charges a fulfillment fee per unit based on the product size tier, shipping weight and price band. The calculator finds the size tier from your box size and weight and applies the 2026 fee table.

Yes. Turn on Offsite Ads and choose 15% or 12% (for shops above $10,000 a year). The fee is charged only on orders that come from those ads and is capped at $100 per order.

TACoS is total ad spend divided by total sales. At 10% TACoS on a $30 product, ads cost $3 per unit sold, which comes straight off your profit. The calculator also shows the most you can spend on ads before a sale loses money.

Enter your return rate and the loss per return, such as the return label and damaged stock. The calculator spreads that loss across every unit sold.

Margin is profit as a percentage of the selling price. ROI is profit as a percentage of what you paid for the stock. A $10 profit on a $40 sale with $15 product cost is a 25% margin and about a 67% ROI.

Walmart takes a referral fee by category (15% for most items, 8% for electronics, 6% for computers) and has no monthly fee; you can ship yourself or use an estimate for Walmart Fulfillment Services. eBay charges a final value fee on the total including shipping (13.6% for most categories) plus $0.40 per order, or $0.30 at $10 or less. TikTok Shop charges a referral fee that includes payment processing (enter 6% or 8% to match Seller Center) plus any creator commission.

Yes. Pick the marketplace to switch the currency, the seller plan and the VAT or GST included in your price. Referral fees use the same category rates, and the FBA fulfillment fee is converted from US rates at your exchange rate, so type the exact fee from Seller Central in the override box for a precise result.

Items over the Large Standard limits (18 x 14 x 8 inches or 20 pounds) that are no more than 37 x 28 x 20 inches, 50 pounds, and 130 inches in length plus girth. The 2026 fee starts at $6.78 under $10 or $7.55 at $10 and above, plus $0.38 per pound over the first pound. Bigger items move to Large Bulky or Extra-large, which has weight bands at 50, 70 and 150 pounds.
