Marketplace fee & margin calculator.

As of 22 Oct 2026, Amazon and Walmart both take a 15% referral fee in many categories, with lower rates in some, such as 8% for consumer electronics. Amazon also charges $39.99 a month on its Professional plan. Walmart has no setup or monthly fee. Faire takes 15% of wholesale orders, plus a $10 new customer fee on a retailer’s first order. Target Plus does not publish its commission. Terms come in its partner agreement.

Under Faire’s brand terms, the first order from a new retailer costs 15% of the order subtotal plus a $10 new customer fee. Reorders cost 15%. Qualified Faire Direct orders, where you bring the retailer to Faire yourself, cost 0%. Faire also charges a payment processing fee. Terms change, so check the current commission in your Faire Brand Portal before you set wholesale prices.

As of 22 Oct 2026, eBay’s final value fee is 13.6% of the sale for most categories, up to $7,500, and 2.35% on the part above that. eBay adds a per-order fee of $0.30 on orders of $10 or less and $0.40 on larger orders. You get 250 free listings a month. After that, each listing costs $0.35.

The referral fee is only part of the bill. Brands often miss FBA storage and aged inventory fees, WFS peak-season storage, return shipping and handling, the ad spend needed to hold search rank, payment processing on Faire and on their own store, and Faire’s $10 new customer fee on each first order. Add each one to the model before you price a SKU for a new channel.

Amazon charges $39.99 a month for a Professional account, or $0.99 per item sold on the Individual plan. Walmart says it has no setup, monthly or hidden fees. Faire earns through commission on orders. Target Plus sets terms in its partner agreement. Your own Shopify store costs $29 to $299 a month on yearly billing, or $2,300 a month for Shopify Plus on a three-year term.

On Amazon and Walmart, the referral fee is the main per-sale charge listed on their pricing pages. Faire adds a separate payment processing fee on top of its commission. On your own Shopify store, you pay the card rate for your plan, which Shopify lists on its pricing page. That rate changes with your plan, so check it again whenever you switch plans.

Start with one SKU. Find its category on each marketplace’s fee page and note the referral rate at your price. Add the fulfillment fee for its packed weight and size, then monthly storage. Add returns and the ad spend you expect per sale. Subtract all of it, plus product cost, from the selling price. Repeat for your top ten SKUs before you commit stock to a new channel.

Walmart Fulfillment Services (WFS) is Walmart’s fulfillment program for Marketplace sellers. You send stock to Walmart’s warehouses, and Walmart stores, packs and ships your orders. Walmart says WFS has no setup or monthly fees. You pay a fulfillment fee per unit, starting at $3.45 for items of 1 lb or less, plus storage of $0.75 per cubic foot per month from January to September.

Weigh and measure the item as packed. Enter those numbers in Walmart’s WFS fee calculator to get the fulfillment fee per unit, which starts at $3.45 for 1 lb or less. Work out the cubic feet you will store, then multiply by $0.75 per month, or more for stock held over 30 days in October to December. Add the referral fee for your category. That total is your WFS cost per unit.

Walmart’s estimator gives the official WFS fee for one item from its weight and size. Our calculator compares five channels side by side from your price, product cost, monthly units, category and weight band. It uses planning rates, so it shows which channel earns more per unit, not your exact Walmart invoice. Use ours to pick channels, then confirm the WFS fee in Walmart’s estimator.

Walmart Marketplace charges a referral fee on each sale and no setup or monthly fee, per its pricing page as of 22 Oct 2026. Many categories pay 15%. Consumer electronics pays 8%. Apparel pays 5% up to $15, 10% from $15 to $20, and 15% above $20. Rates run from 3% to 20% across categories. WFS fulfillment and storage are extra if you use them.

Profit per unit is your selling price minus product cost, the referral fee, the WFS or shipping cost, storage, returns and ad spend. Enter your price, product cost, monthly units, category and weight band in the calculator above. It shows profit per unit and per month next to Amazon, Target Plus, Faire and Shopify. Then check the exact WFS fee in Walmart’s own calculator.

Walmart does not publish average seller earnings, and we will not guess at one. Earnings depend on your category, price, packed weight, ad spend and how many units you sell. The useful number is your own profit per unit. Run your SKUs through the calculator above, then multiply by the monthly volume you expect to see a realistic figure for your business.

It is worth testing when your price still leaves profit after Walmart’s referral fee and fulfillment. Walmart charges no setup or monthly fee, so a small test costs little beyond your time and stock. Start with a few SKUs that already sell well elsewhere, run them through the calculator, and list the ones that clear your margin target.

On orders you ship yourself, you pay your carrier, so negotiated rates and smaller boxes cut the bill. On WFS, shipping sits inside the per-unit fulfillment fee, which rises with weight and size. Trimming packed weight below a tier line, such as 1 lb, moves the item to a lower fee. Check the result in Walmart’s WFS fee calculator before you change packaging.

Walmart says WFS has no setup or monthly fees, and Walmart Marketplace has no monthly fee. Amazon’s Professional plan costs $39.99 a month, or the Individual plan charges $0.99 per item sold. Both programs then charge per-unit fulfillment and monthly storage once stock arrives. So your first real cost on either is the inventory you send in and the freight to get it there.

Walmart claims WFS saves sellers 15% on fulfillment cost per item compared with other marketplace fulfillment providers, based on its own comparison of orders from 1 July 2024 to 30 June 2025. That is Walmart’s claim, not an independent test. FBA fees vary by size tier and weight and are listed on Amazon’s FBA page. Price the same SKU on both before you move stock.

Target Plus partners ship orders from their own warehouse or 3PL. Target’s application page lists the rules: ship with UPS, USPS or FedEx, ship within a 24-hour lead time, deliver within 2 to 5 business days after shipping, and fulfill from the US only. You keep control of storage, packing and carrier rates, but you cannot use competitor fulfillment services.

Each return costs you the refund plus the handling. If you use FBA or WFS, check their fee pages for any return charges in your category. On seller-fulfilled channels you process returns yourself. Target requires Target Plus partners to accept both single-parcel and palletized returns from a semi-truck at a business location, so budget dock space and labor for that.

WFS storage is $0.75 per cubic foot per month from January to September. From October to December, the first 30 days stay at $0.75, then Walmart adds $1.50 per cubic foot per month beyond 30 days. Check Amazon’s FBA pages for its peak-month storage rates too. Send holiday stock in close to when it will sell, so it does not sit in storage for long.

Running your own site next to marketplaces means two fulfillment bills unless you share stock. FBA and WFS hold their own stock and charge per unit plus storage. Your site and seller-fulfilled channels such as Target Plus and Faire ship from your warehouse or 3PL. One shared stock pool for those channels cuts safety stock and double handling.

There is no single healthy number, and we do not publish one. Margin depends on your category, price, packed weight and ad spend. Use the calculator with your own price and product cost, then add your real ad cost per sale. If a channel cannot cover its fees and ads at your current price, fix the price or the pack size before you list.

One price across channels is the safe default. Amazon and Walmart both compare outside prices, and a lower price elsewhere can cost you the Buy Box. Set a Minimum Advertised Price, keep marketplace prices at or above it, and run deeper deals through private codes on your own store. Check each marketplace’s current pricing policy in its seller help center.

Faire orders are wholesale, so the price is what the retailer pays you, not the shelf price. Set wholesale from your own product cost first, then check it still works after Faire’s 15% commission and the $10 fee on opening orders. Move existing retailers onto Faire Direct, which costs 0% on qualified orders. Faire gives retailers 60 days to pay, interest-free.

Amazon charges an aged inventory surcharge on FBA stock that sits too long, with the age bands and rates on its FBA fee pages. WFS charges an extra $1.50 per cubic foot per month on stock held beyond 30 days in October to December. Track days of cover per SKU, then run a promotion or pull stock back to your own 3PL before those fees start.

We build one inventory and order hub that connects your core platform, such as Shopify Plus, BigCommerce or your ERP, to the Amazon SP-API, the Walmart Marketplace API, the Target Plus integration and the Faire API. Each sale updates the shared stock count, and the new count goes out to every channel, so no marketplace keeps selling stock you no longer have.

When warehouse stock drops below a safety level you set, our rules set marketplace quantities to zero and keep the last units for your own store. That stops marketplaces from taking orders you cannot ship, which protects your seller account rating. You choose the buffer per SKU, and you can raise it ahead of a sale or a holiday spike.

Yes. Orders from Amazon, Walmart, Target Plus and Faire flow into your main fulfillment queue or warehouse management system (WMS) on their own. The system then creates carrier labels and packing slips that meet each channel’s rules. Your team picks and packs from one list instead of copying orders from four seller portals by hand.

We build two-way connectors for NetSuite, SAP, Microsoft Dynamics 365, Acumatica, Katana Cloud Manufacturing, QuickBooks Enterprise, and custom PostgreSQL or REST backends. Orders, stock counts and settlement data move between the ERP and each channel, so finance closes the month from one set of numbers instead of separate marketplace reports.

Each marketplace uses its own categories and attribute fields for size, color and other variants. Our mapping pipeline converts your master product data into each channel’s format, so you edit a product once and every listing updates. Nobody types the same SKU into four portals, and a missing required field shows up as an error before the listing goes live.

We quote the timeline in writing after scoping, because it depends on how many channels and systems you connect. For reference, our store builds run 3 to 5 weeks for a custom theme, 5 to 8 weeks for advanced work such as subscriptions, B2B or migration, and 8 to 14 weeks for headless or custom builds.

We quote a fixed price per phase, in writing, after scoping. Before you sign, we show you working software on your own data, so you see it run first. Every build includes defect cover for a stated period, and there is no monthly minimum. We never take a percentage of your revenue.

Book a 30-minute scoping call directly with Bhavesh Barot. We review your current channel mix, catalog structure and fulfillment workflow on the call. Afterwards you get a written plan with a fixed price for each phase, so you can decide on the first step without committing to the whole program.
