Marketplace vs Own Store Fee Comparison Calculator

Most sellers drastically underestimate what marketplaces actually cost them. When you add up listing fees, transaction fees, payment processing, offsite ads, FBA fulfillment, storage, and advertising, the real total can consume 30–50% of your revenue — sometimes more. This guide walks through every fee layer on Etsy, Amazon, and eBay, gives you the formulas to calculate your own numbers, and shows exactly when it makes financial sense to move to your own store.

Why Sellers Underestimate Marketplace Fees

The reason most sellers underestimate their fees is structural: platforms display fees in isolation. Etsy shows you a 6.5% transaction fee. Amazon shows you a 15% referral fee. Neither platform hands you a single number that adds everything together.

In reality, every marketplace charges fees across multiple independent categories that stack on top of each other:

• •Percentage of sale fees — the most visible layer, but rarely the only one
• •Per-transaction or per-listing flat fees — small individually, significant at scale
• •Payment processing fees — often treated as a card-processing cost but captured by the platform
• •Fulfillment and storage fees — relevant for Amazon FBA sellers
• •Advertising fees — technically optional but practically mandatory for visibility
• •Offsite advertising fees — Etsy-specific, often forgotten entirely

When you calculate all of these together for a $5,000/month business, the true rate often lands between 15% and 46% of gross revenue, depending on the platform. That gap matters enormously for long-term profitability.

Etsy Fee Breakdown 2026

Etsy has one of the most layered fee structures of any marketplace. Here is every charge you need to account for.

Listing Fee

Etsy charges $0.20 per listing, renewed every four months. If you have 200 active listings and sell items frequently (triggering auto-renewal), listing fees alone can reach $40–$100 per month. Most guides skip this because the per-unit cost looks trivial. Over a year with a large catalog, it is not.

Formula: Active Listings × $0.20 × (Monthly Sales / Listings Sold)

Transaction Fee

Etsy charges 6.5% of the total sale price, including whatever shipping amount the buyer pays. If you charge $45 for an item and $6 for shipping, Etsy takes 6.5% of $51 = $3.32. Sellers who offer free shipping absorb this implicitly; those who charge shipping often forget that the fee applies to the shipping amount too.

Formula: (Item Price + Shipping Charged) × 0.065

Payment Processing Fee

If you use Etsy Payments (required in most countries), you pay 3% + $0.25 per transaction on top of the transaction fee. This is a separate line item. For a $51 order: $51 × 3% + $0.25 = $1.53 + $0.25 = $1.78.

Formula: (Total Sale × 0.03) + ($0.25 × Order Count)

Offsite Ads Fee

This is the single most-overlooked Etsy fee. Etsy automatically enrolls sellers in its Offsite Ads program. When a buyer clicks one of Etsy's ads on Google, Facebook, Instagram, or Pinterest and then purchases within 30 days, Etsy charges an additional 12% fee (for sellers above $10,000 in annual revenue) or 15% (for sellers below $10,000).

Sellers who make more than $10,000 per year on Etsy cannot opt out. Etsy estimates that roughly 30–40% of sales come through offsite ad clicks, though this varies by niche.

Formula: Total Sales × Offsite Ad Traffic % × (0.12 or 0.15)

Total Etsy Fee Example

For a $5,000/month seller with 200 listings, $6 average shipping charged, and 35% offsite ad traffic:

Amazon FBA Fee Breakdown 2026

Amazon FBA sellers face the highest combined fee burden of any major marketplace. The layers are more numerous and the individual amounts are larger.

Referral Fee

Amazon charges a referral fee on every sale, ranging from 8% to 17% depending on product category. The most common categories (home, kitchen, clothing, toys) are at 15%. Electronics drop to 8%. Jewelry can reach 20%.

Formula: Sale Price × Category Referral Rate

FBA Fulfillment Fee

If you use FBA, Amazon charges a per-unit fulfillment fee based on product size and weight. For a small standard item (under 16 oz), this runs $3.06–$3.65. For a large standard item (under 20 lbs), it runs $3.68–$6.92. Oversized items go much higher.

Formula: Orders × Average FBA Fulfillment Fee Per Unit

Monthly Storage Fee

Amazon charges for the cubic footage your inventory occupies in their warehouses. The rate is $0.78 per cubic foot from January through September and spikes to $2.40 per cubic foot from October through December (the holiday season surcharge). Sellers who over-stock face disproportionate Q4 storage costs.

Formula: Average Inventory × Cubic Feet Per Unit × Storage Rate

Advertising (Effectively Required)

Amazon's search algorithm heavily rewards sellers who run Sponsored Products ads. New listings and competitive categories require advertising spend to gain visibility. Industry averages run 15–25% of revenue in ad spend. This is technically optional, but sellers who skip advertising in most categories see minimal organic sales.

Formula: Monthly Revenue × Ad Spend %

eBay Fee Breakdown 2026

eBay's structure is simpler than Amazon's but still has multiple components.

Final Value Fee

eBay charges a final value fee on the total amount the buyer pays, including shipping and any applicable taxes. For most categories, this is 13.6% + $0.30 per order (for orders over $10, it is $0.40). Certain categories like motors have different rates, but for most consumer goods, 13.6% is the operative rate.

One key detail: unlike Amazon, eBay's final value fee includes payment processing. There is no separate processing charge for eBay Managed Payments sellers.

Formula: (Item Price + Shipping) × 0.136 + $0.30 (or $0.40 for orders > $10)

Store Subscription (Optional)

eBay sellers can subscribe to an eBay Store for a monthly fee, which lowers their final value fee rates and increases free listing allotments. Plans in 2026:

• •Starter: $7.95/month
• •Basic: $27.95/month
• •Premium: $74.95/month
• •Anchor: $349.95/month

For sellers doing significant volume, the reduced final value fees often offset the subscription cost. For lower-volume sellers, the free tier is usually more economical.

Promoted Listings

eBay's Promoted Listings program works differently from Amazon's: you only pay the promotion fee when an item sells via a promoted placement. Rates are variable and set by the seller or by eBay's suggested rate. Typical rates run 2–8% of the sale price for general merchandise.

Formula: Sales from Promoted Listings × Promotion Rate

Own Store Cost Breakdown

Running your own store eliminates marketplace percentage fees but introduces fixed and variable costs of a different structure.

Platform Fee

Shopify remains the most common own-store platform for marketplace sellers transitioning to direct-to-consumer:

• •Basic: $29/month (2.9% + $0.30 processing)
• •Shopify: $79/month (2.6% + $0.30 processing)
• •Advanced: $299/month (2.4% + $0.30 processing)

AI-powered store builders like Stable Commerce can launch your store faster and with less ongoing technical maintenance, often making the transition significantly smoother for sellers coming off marketplaces.

Payment Processing

With Shopify Payments, you pay 2.9% + $0.30 per transaction on the Basic plan. Third-party processors (Stripe, PayPal) run similarly. There is no referral fee on top of this — payment processing is your total platform cost per transaction.

Formula: (Monthly Revenue × 0.029) + ($0.30 × Order Count)

Marketing and Advertising

The largest variable cost for own store sellers is customer acquisition. Unlike marketplaces, you are not borrowing someone else's traffic. Budget ranges vary widely by niche and approach, but a realistic starting point is $150–$500/month for a seller doing $5,000/month in revenue.

The important nuance: marketing spend on your own store builds durable assets (email list, remarketing audiences, social following). Marketplace advertising spend builds the marketplace's data assets, not yours.

Apps and Tools

Shopify's ecosystem means some features require paid apps: email marketing, reviews, loyalty programs, subscriptions. Budget $0–$100/month depending on which tools you need.

Side-by-Side Comparison Table

For a $5,000/month seller in a general merchandise category:

These numbers illustrate why the fee comparison matters at scale. A 4-percentage-point difference between Etsy (15.3%) and own store (11.1%) translates to $2,472 in annual savings on just $5,000/month in revenue. Scale to $15,000/month and the same rate difference saves over $7,000/year.

Hidden Fees and Easy-to-Miss Costs

Beyond the headline rates, each platform has less-visible charges that frequently surprise sellers.

Etsy Hidden Costs

• •Listing renewals for unsold items: Listings that don't sell still renew automatically every four months at $0.20.
• •Currency conversion: Non-US sellers receive payments in their local currency and may face conversion fees.
• •Pattern (Etsy's website tool): $15/month if you use Etsy's standalone website builder. This is often forgotten when calculating total Etsy costs.
• •Star Seller program requirements: Not a direct fee, but maintaining Star Seller status requires specific shipping and response-time commitments that have indirect costs.

Amazon Hidden Costs

• •Long-term storage fees: Inventory stored more than 365 days incurs an additional $6.90 per cubic foot surcharge.
• •Returns processing fees: Amazon charges sellers return processing fees on certain categories.
• •Aged inventory surcharge: Items stored 181–365 days incur a surcharge of $0.50–$1.50 per unit.
• •Low-inventory-level fees: Sellers with inventory levels below historical demand averages can be charged an additional fee.
• •Removal fees: If you want to retrieve or dispose of inventory, there are per-unit fees to do so.

eBay Hidden Costs

• •Insertion fees above free allotments: Free listings have category and quantity limits; exceeding them costs $0.35 per listing.
• •International selling fees: Sales to international buyers in certain country combinations trigger additional fees.
• •Dispute fees: Unresolved buyer disputes can result in fees charged to sellers.

How Payment Processing Compounds Your Costs

Payment processing is one of the most misunderstood components of marketplace fee analysis. Here is why it matters more than sellers often realize.

On Etsy, you pay two separate percentage fees on the same sale: the 6.5% transaction fee and the 3% payment processing fee. Together they represent 9.5% of your gross revenue before the offsite ads fee. This stacking effect means the marginal cost of a sale is higher than either fee suggests on its own.

On Amazon, payment processing is bundled into the referral fee — you do not pay a separate processing charge, but the referral rate is high enough that the bundled cost still exceeds what you would pay on your own store.

On your own store using Shopify Payments, you pay 2.9% + $0.30 as your total per-transaction cost. There is no additional percentage fee layered on top. This is the core structural advantage of own-store payment processing: you pay once, at the processor's rate, with no marketplace layer on top.

The per-transaction flat fee ($0.25 on Etsy, $0.30 on Shopify) matters more for low-average-order-value sellers. For a seller with a $15 average order value, the $0.25 flat fee represents an additional 1.7% of the transaction. For a seller with a $100 average order value, it is only 0.25%.

How to Use the True Cost Calculator

Step 1: Gather Your Business Numbers

Pull the following from your marketplace dashboards before entering any formulas:

Step 2: Calculate Each Fee Layer

Use the formulas in the platform-specific sections above. Start with Etsy or your current primary platform and work through each fee category line by line. Resist the urge to skip categories because they "seem small" — the compounding of multiple small percentages is exactly what creates the 15–46% spread.

Step 3: Build the Comparison

Run the same revenue and order count through the own-store formula. Use $29/month for Shopify Basic, 2.9% + $0.30 for processing, and an honest estimate for marketing spend (not zero — you will need to acquire customers).

Step 4: Calculate Annual Impact

Monthly savings × 12 = Annual savings. This number is the amount you could invest in product development, inventory, or marketing if you moved to an own store. It is also the benchmark against which to measure the effort and cost of making the transition.

Step 5: Assess the Break-Even Point

If you run both a marketplace and an own store simultaneously (the hybrid approach), you need a minimum revenue level on the own store to justify its fixed costs. The break-even formula:

Own Store Break-Even Revenue = Fixed Costs / (Marketplace Fee Rate - Own Store Variable Fee Rate)

For example: Shopify Basic ($29) + Apps ($50) + minimum marketing ($150) = $229 in fixed monthly costs. If Etsy charges 15.3% and own store costs 3% variable (processing only), the spread is 12.3 percentage points. Break-even revenue = $229 / 0.123 = $1,862/month on the own store.

Once your own store exceeds that threshold, every additional dollar of sales generates more net revenue than it would on Etsy.

How Fees Compound Over Time

The annual impact of marketplace fees compounds in a way that short-term thinking obscures. Consider a seller growing at 20% per year starting at $5,000/month.

Over five years, the fee difference accumulates to nearly $19,000 in savings — money that would otherwise fund your inventory, product development, or simply remain as profit. The longer you wait to evaluate the comparison, the larger the opportunity cost grows.

For Amazon sellers, the compounding is even more dramatic given the 46% effective rate. A seller doing $5,000/month who moves even 50% of their volume to an own store and reduces their blended rate from 46% to 28% saves roughly $10,800 per year.

When It Makes Sense to Move to Your Own Store

The fee comparison alone does not make the case for moving. Here are the full set of factors that indicate an own store is the right next step.

Strong Case: Move Now

• •Own store saves 30%+ of fees vs your current marketplace
• •You have repeat customers who would follow you off the marketplace
• •Your brand has distinct identity that the marketplace suppresses
• •You are at risk from marketplace policy changes (Etsy offsite ads, Amazon seller suspensions)
• •You want to own your customer data and email list

Moderate Case: Hybrid Approach

• •Own store saves 10–30% of fees
• •Your marketplace still drives significant new customer discovery
• •You are willing to use the marketplace for acquisition and own store for retention
• •You have the capacity to manage two sales channels simultaneously

Wait and Re-Evaluate

• •Own store savings are less than 10%
• •You are still growing rapidly on the marketplace and building reviews/social proof
• •You lack the time or resources to manage customer acquisition independently
• •Your product category is deeply tied to marketplace search behavior

The hybrid approach — keeping marketplace presence for customer acquisition while building an own store for repeat customers — often represents the optimal path. Marketplaces are expensive customer acquisition channels. Your own store is where profitable long-term relationships live.

What to Do With Your Results

If Own Store Saves 30%+ vs Your Marketplace

Strong case for building your own store. Even accounting for the time investment involved, the savings are significant. A $2,500+ annual savings at $5,000/month scales linearly — at $15,000/month, you are looking at $7,500+ per year. The transition cost amortizes quickly.

If Own Store Saves 10–30%

Worth considering the hybrid approach. Keep marketplace presence for customer discovery. Route repeat buyers to your own store. Build your email list from marketplace orders using inserts or post-purchase sequences where marketplace terms allow.

If Own Store Saves Less Than 10%

May not be the priority right now. Focus on growing revenue on your current platform, then revisit the analysis at a higher revenue level where the percentage savings represent a larger absolute dollar amount. Other factors — brand control, customer data ownership, policy risk — may still justify the move even if the fee savings are modest.

Tips for Accurate Calculations

1. •Use actual numbers, not estimates — Pull from Etsy/Amazon dashboards rather than guessing
2. •Include ALL fee categories — Offsite ads are the most commonly forgotten Etsy fee
3. •Be realistic about advertising — Own store needs a marketing budget; use a real number, not zero
4. •Account for time costs — Marketplaces handle fulfillment administration and some customer service
5. •Consider the hybrid approach — You do not have to choose one channel exclusively
6. •Re-run the analysis annually — Fee structures change, and your revenue mix may shift

The Bottom Line

Marketplace fees are the single largest controllable cost in most online sellers' businesses — and most sellers never calculate the full number. Once you do, the math becomes obvious: every percentage point you reclaim through lower-fee channels compounds over years of sales.

Your own store doesn't replace your marketplace presence. It complements it — capturing repeat buyers, reducing your effective fee rate, and building an asset you own. The question isn't whether the math works. It's when you're ready to act on it.

Frequently Asked Questions

What are Etsy's total fees in 2026?

Etsy charges four main fee categories: a $0.20 listing fee per item, a 6.5% transaction fee on the full sale price including shipping, a 3% + $0.25 payment processing fee, and an offsite ads fee of 12–15% on sales that originate from Etsy's external advertising. For a typical seller, the combined effective rate lands between 12% and 18% of gross revenue, with the offsite ads fee being the most commonly underestimated component.

How do Amazon fees compare to Etsy?

Amazon FBA fees are significantly higher than Etsy's in most scenarios. A typical Amazon seller pays a 15% referral fee, $3–7 per unit in FBA fulfillment fees, storage charges, and 15–25% in advertising spend — bringing the effective rate to 35–50% of gross revenue. Etsy's effective rate for the same seller would typically be 12–18%. The gap makes Amazon's marketplace cost far more expensive, though Amazon's traffic volume and fulfillment infrastructure provide offsetting value for certain product categories.

What are eBay's selling fees?

eBay's primary fee is the final value fee, which is 13.6% of the total buyer payment (including shipping) plus $0.30–$0.40 per order for most categories. Unlike Etsy and Amazon, eBay's final value fee includes payment processing, so there is no separate processing charge. Optional eBay Store subscriptions range from $7.95 to $349.95/month and reduce the final value fee rates for sellers with significant volume. Promoted Listings add a variable fee (typically 2–8%) only when a promoted item sells.

Are there hidden fees I'm missing?

Yes, on every platform. Etsy's most-overlooked fee is the offsite ads charge (12–15% on qualifying sales), which sellers above $10,000/year cannot opt out of. Amazon's hidden costs include long-term storage fees ($6.90/cu ft after 365 days), aged inventory surcharges, returns processing fees, and low-inventory-level fees. Running a complete fee audit using actual dashboard data — not just the published rate cards — is the only reliable way to find all of them.

How do my own store fees compare to marketplace fees?

An own store's effective fee rate is typically 8–14% of gross revenue once you account for platform fees, payment processing, and marketing spend. The key difference is structural: instead of paying percentage fees to the marketplace on every sale, you pay a flat platform fee plus a lower percentage for payment processing alone. The marketing cost on your own store is real, but it builds assets you own (email list, audience data), whereas marketplace advertising builds the platform's data. For most sellers doing over $2,000/month, own-store fees are lower than Etsy fees and dramatically lower than Amazon FBA fees.

How does payment processing affect total cost?

Payment processing is often double-counted or misunderstood in fee comparisons. On Etsy, you pay both a 6.5% transaction fee and a separate 3% + $0.25 processing fee — these stack on the same sale. On your own store with Shopify Payments, you pay 2.9% + $0.30 with no additional marketplace layer on top. The stacking of fees on marketplace platforms is the main reason the effective rate is significantly higher than the headline transaction fee suggests. For a $50 sale on Etsy, that stacking adds $3.25 in transaction fees that have no equivalent on your own store.

What's the break-even point for moving off a marketplace?

The break-even point depends on your own store's fixed costs and the fee-rate spread between platforms. The formula is: Fixed Monthly Costs divided by (Marketplace Fee Rate minus Own Store Variable Fee Rate). For a seller moving from Etsy (15.3% effective) with $229/month in fixed own-store costs, break-even revenue is approximately $1,862/month on the own store. Above that threshold, every additional dollar of own-store sales generates more net revenue than the same dollar on Etsy.

How much can I save by switching from Etsy to my own store?

At $5,000/month in revenue, the average Etsy seller saves approximately $206/month ($2,472/year) by shifting to an own store. At $10,000/month, that scales to roughly $412/month ($4,944/year). The savings grow proportionally with revenue because most of the cost difference comes from percentage-based fees. Amazon sellers see even larger savings — a seller doing $5,000/month on Amazon FBA can save $1,700+ per month by moving to an own store, though they lose the FBA fulfillment convenience and must handle logistics independently.

Does Stable Commerce help reduce fees?

Stable Commerce is an AI-powered store builder designed specifically for marketplace sellers who want to launch their own store quickly. It handles store setup, product importing from your existing marketplace listings, and theme customization — reducing the time and technical barrier that often delays the transition. Once your Stable Commerce store is live, you pay standard Shopify processing rates (2.9% + $0.30) with no additional marketplace fee layer, which is the same structural fee advantage as any Shopify store. Start your free trial to see how it works for your specific situation.

How do I calculate my effective fee rate?

Your effective fee rate is the percentage of your gross revenue that goes to platform fees in total. To calculate it: add up every fee you paid to the platform in a given month (listing fees, transaction fees, processing fees, advertising fees, FBA fees, storage fees — everything), then divide by your total gross revenue for that month, and multiply by 100. The result is your true effective fee rate. Most sellers find this number is significantly higher than the headline transaction fee suggests when all categories are included. Running this calculation quarterly gives you an accurate, current picture of your real platform cost.

Should I use a hybrid marketplace-plus-own-store strategy?

A hybrid strategy — maintaining marketplace presence for customer discovery while building an own store for repeat buyers — is often the optimal path for established sellers. Marketplaces are expensive but effective customer acquisition channels. Your own store is where repeat customers generate the most profit because you eliminate the percentage fee on every transaction. To execute the hybrid approach, keep your marketplace listings active and optimized, but use every post-purchase touchpoint (order confirmations, packaging inserts, follow-up emails where terms permit) to encourage customers to shop directly with you next time. Over 12–18 months, a growing share of your revenue shifts to the lower-cost channel.
