Selling online has never been more accessible — but the true cost of each platform is often buried in complex, multi-layered fee structures. This guide breaks down selling fees across every major marketplace so you can choose the right platform, price your products accurately, and protect your profit margin.

Why Platform Fees Matter More Than You Think

A 2% difference in platform fees might seem trivial on a single sale, but for a seller doing $50,000 in annual revenue, that’s $1,000 in additional profit — or lost fees. Choosing the right marketplace for your product category and volume can make the difference between a thriving business and one that barely breaks even.

eBay: The Largest General Marketplace

eBay charges a final value fee between 13.25% and 15.3% depending on category, plus a $0.30 per-order fee. Despite being one of the more expensive platforms by percentage, eBay’s massive buyer base and no-listing-fee policy for the first 250 items per month make it the default choice for most general merchandise sellers.

Top Rated Sellers receive a 10% discount on final value fees, and store subscriptions reduce fees further for high-volume sellers. Calculate your exact eBay profit with our eBay Fee Calculator.

Amazon FBA: Scale with Fulfillment

Amazon FBA (Fulfilled by Amazon) is fundamentally different from other marketplaces — you send inventory to Amazon’s warehouses and Amazon handles storage, packing, shipping, and customer service. In exchange, you pay a referral fee (6–15% depending on category) plus an FBA fulfillment fee based on item size and weight.

For branded product sellers who want to scale, Amazon FBA’s reach and Prime eligibility are unmatched. But the combination of fees — referral + fulfillment + storage — requires careful margin analysis before listing. Use our Amazon FBA Calculator to see your true profit before committing inventory.

Etsy: Best for Handmade and Digital Products

Etsy’s 6.5% transaction fee is lower than most competitors, but the $0.20 listing fee per item and the potential 15% Offsite Ads fee can significantly cut into margins for low-priced items. For digital downloads — printables, templates, patterns, and audio files — Etsy is hard to beat: no shipping, no COGS, and the largest dedicated buyer base for digital creative products.

Mercari and Depop: Resale Platforms Compared

Both Mercari and Depop charge 10% selling fees, but differ in their audiences and payment processing costs. Depop skews strongly toward fashion, streetwear, and vintage clothing with a Gen Z buyer base. Mercari is broader, accepting electronics, toys, home goods, and clothing. Depop’s processing fee (3.3% + $0.45) is slightly higher than Mercari’s (2.9% + $0.50) for most transaction sizes.

Reverb: The Instrument Seller’s Best Option

Reverb’s 5% selling fee capped at $500 per transaction makes it the cheapest option for high-value musical gear by far. A $10,000 vintage guitar costs $500 in Reverb fees vs $1,360 on eBay. For serious gear sellers, Reverb isn’t just cheaper — it’s the most qualified buyer audience for instruments.

How Marketplace Fees Are Actually Structured

Most marketplace fees are not simple flat percentages. They consist of multiple layers — listing fees, final value fees (which may vary by category), payment processing fees built in or separate, optional promotional fees, and performance-based adjustments. Understanding each layer prevents the common mistake of calculating profit based only on the headline fee rate.

eBay’s Multi-Tier Fee System

eBay’s final value fee varies significantly by category. Electronics and computers can be as low as 2.35%, while most general merchandise runs 13.25–15.3%. The $0.30 per-order fee is fixed regardless of sale price — making it disproportionately expensive on low-value items (on a $5 item, $0.30 alone represents 6%). Sellers with eBay Stores pay lower rates and receive higher free listing allowances, but must weigh subscription costs ($4.95–$2,999.95/month) against fee savings.

The Top Rated Seller discount (10% off final value fees) requires: 100+ transactions AND $1,000+ in sales in the prior 12 months, below-standard rate under 0.5%, late shipment rate under 3%, cases closed without seller resolution under 0.3%, and tracking uploaded within handling time on 95%+ of transactions. Earning and maintaining TRS status is the single most impactful fee reduction available to eBay sellers. Use our eBay Fee Calculator to model TRS vs standard rates.

Amazon FBA: The Three-Fee Stack

Amazon FBA sellers pay three distinct fee layers that compound: a referral fee (percentage of sale price by category), an FBA fulfillment fee (based on item size tier and weight), and a monthly storage fee (per cubic foot, higher October–December). A $20 item in the “small standard” size tier might have: $3.00 referral (15%) + $3.22 FBA fulfillment fee + $0.05 estimated monthly storage = $6.27 in Amazon fees, leaving $13.73 before your cost of goods and inbound shipping.

Long-term storage fees (for inventory held over 365 days) and returns processing fees add further layers. Amazon FBA is only profitable when inventory turns quickly, margins are healthy before fees, and products have a clearly differentiated position to maintain price. Our Amazon FBA Calculator applies all three fee layers simultaneously.

How to Calculate True Profit on Any Marketplace

The correct formula for calculating marketplace profit is often more complex than sellers realize. Use this framework:

Selling Across Multiple Platforms: Pros, Cons, and Inventory Management

Listing the same item on multiple platforms simultaneously (cross-listing) maximizes exposure but creates operational complexity. If an item sells on eBay while still listed on Mercari, you risk a double-sale and negative feedback on whichever platform you cancel. Tools like List Perfectly, Vendoo, and Crosslist automate cross-platform listing and can sync inventory status to delist sold items across all channels within minutes.

The practical rule: cross-list items you own multiple units of, or items that sell slowly. For one-of-a-kind vintage pieces, single-platform listing reduces operational risk while multi-platform tools handle the rest of your inventory more safely.

Tax Obligations for Marketplace Sellers

All marketplace platforms now issue 1099-K forms to sellers who exceed $5,000 in gross payments in 2024 (with a proposed $600 threshold for 2025 and beyond, pending IRS guidance). The 1099-K reports gross sales — not profit. Your actual taxable income is gross sales minus COGS, platform fees, shipping costs, and other business expenses. Keep meticulous records of all costs to accurately calculate your net Schedule C income.

Sales tax is collected and remitted by most major platforms under marketplace facilitator laws in all 45 sales-tax states. As a seller, you generally do not need to collect or remit sales tax on sales through eBay, Etsy, Amazon, Mercari, or Depop — the platform handles it. However, sales on your own website or through non-facilitator channels remain your responsibility.
