The marketplace with the smallest headline percentage does not automatically leave you with the most money. One platform may charge commission on the sale price, another may add payment processing on shipping and buyer tax, and a third may shift part of the charge to the buyer. Shipping, demand, returns, promoted listings, and the price you can actually achieve often matter more than a one-point fee difference.
The honest comparison is item-specific: put the same sale into each marketplace model, then compare the estimated payout and profit against the buyer demand you can realistically reach.
Which selling platform has the lowest fees?
There is no single answer across every item and selling format.
- Local pickup can have very low platform fees, but the seller takes on messaging, meet-up, payment, and no-show risk.
- Closet and fashion marketplaces may simplify labels or bring a concentrated buyer pool, but the fee and offer culture can change the achievable price.
- General marketplaces can offer broader demand while using category-specific fee bases, order charges, store tiers, or optional promotion.
- Live selling adds commission and processing while making room size and auction format part of the price outcome.
- Buyer-fee models may look inexpensive to the seller, but the buyer’s all-in checkout price can still affect conversion.
Start with net payout, not the logo at the top of the listing form.
The fee comparison that matters
For each marketplace, calculate:
Net profit = item price + buyer-paid shipping − seller fees − seller-paid shipping − item cost − supplies − other costs
That formula is simple. The fee base is not. Before trusting the result, answer these questions:
- Is commission charged on item price only, or on shipping and buyer tax too?
- Is payment processing separate from commission?
- Is there a fixed order, listing, or transaction charge?
- Does the category use a different rate?
- Does a store subscription or seller tier change the rate?
- Are promoted listings, offsite ads, boosts, or currency conversion included?
- Is the marketplace local-pickup math being mixed with shipped checkout?
- Is any buyer fee likely to change what the buyer will pay for the item itself?
If two platforms are within a few dollars, the next decision is not “pick the lowest fee.” It is “which platform is more likely to sell this exact item at the modeled price and condition?”
Current source map
The broad comparison calculator was reviewed against official platform pages on August 20, 2026. Fee programs change, so the calculator flags unsupported or volatile cases instead of pretending every account has the same rate.
| Platform | Official fee source | Important scope question |
|---|---|---|
| eBay | Selling fees | Category, store status, total amount of sale, per-order fee, and optional promotion. |
| Mercari US | Seller fees | Current seller-fee program and which transactions it applies to. |
| Poshmark US | Seller fees | Flat fee below the threshold versus percentage fee above it. |
| Depop | Seller fees and charges | Seller location, payment processing, Boost, and any legacy PayPal flow. |
| Whatnot | Seller fees | Commission base versus processing base, category, region, tax, and promotions. |
| Etsy | Fees and payments policy | Listing, transaction, processing, currency, and optional ad programs. |
| Vinted | Is selling free? | Personal-selling scope, buyer-side charges, and any Pro or regional rules. |
| Facebook Marketplace | Shipped-order fee scope | Local pickup and shipped checkout are different workflows. |
For Amazon, StockX, Vestiaire, and any specialist platform, use that provider’s current seller schedule and your account tier. Do not copy a percentage from a general article into a category with account-specific or tiered economics.
Calculate your exact scenario before you list
The platform fee comparison is the broad-intent tool for this job. Enter the sale price, acquisition cost, buyer- and seller-paid shipping, buyer tax where relevant, other costs, and target profit. The output shows the modeled fee, payout, profit, effective rate, and which assumptions need checking.
The separate eBay, Mercari, and Poshmark calculator remains useful when those marketplace-specific inputs are the point of the comparison. It is not a duplicate or redirect alias.
How the marketplaces differ in practice
eBay
eBay’s rate depends on category and seller setup, and the fee base can include more than the item price. Use the exact category you intend to list in. If you use a promoted listing, add that cost separately rather than hiding it inside a generic “eBay fee.”
eBay can still win with a higher modeled fee when it produces stronger sold evidence, broader demand, or a higher achievable price for the exact model.
Poshmark
Poshmark uses different treatment below and above its small-sale threshold. The shipping workflow and fashion-oriented buyer base may remove work for some sellers. Model offers at the price you are likely to accept, not the optimistic list price.
Mercari
Mercari’s fee program has changed more than once. That is precisely why a dated blog percentage should not be the source of truth. Open the live seller-fee page, confirm the current transaction scope, and use the expected accepted offer in the calculator.
Depop
Depop’s seller cost depends on location and payment flow, and optional Boost can materially change the sale. Separate ordinary payment processing from promotional spend. For a bundle, also check whether the shipping amount and discount still leave the target profit.
Whatnot
Whatnot calculates commission and processing on different bases. Auction format introduces another variable: the sale price itself. Run a conservative winning bid through the Whatnot fee calculator before choosing a low start.
Etsy
Etsy can combine listing, transaction, payment-processing, currency, and advertising costs. It may still fit handmade, vintage, or supply inventory when the buyer intent supports a better price. Model optional ad exposure separately so you can see whether it is earning its cost.
Vinted and buyer-fee marketplaces
A zero or low seller fee is not the same as a free transaction for the buyer. Check the buyer’s checkout total and local rules. If the buyer absorbs more fees, the item may need a lower list price to remain competitive.
Facebook Marketplace
Local pickup is not the same fee or risk model as shipped checkout. For local deals, put a value on travel, time, payment risk, and no-shows. A platform fee of zero does not make an hour-long failed meet-up free.
A $50 item can produce different “best” answers
Suppose an item costs $12, needs $2 of supplies, and is likely to sell for around $50. One marketplace offers a higher likely sale price but charges more. Another charges less but attracts offers closer to $38. A local buyer avoids shipping but requires two rounds of messages and a 20-minute drive.
The correct comparison has at least three rows per channel:
| Scenario | Price input | Why run it |
|---|---|---|
| Optimistic | Full target price | Shows the upside if the listing performs. |
| Expected | Likely accepted offer | Best estimate for planning. |
| Floor | Lowest price you would take | Shows whether the channel can create a loss. |
Compare profit at the expected and floor rows. If a channel only looks attractive in the optimistic row, it is not the safest default.
Do not ignore sell-through and labor
A $3 fee saving is irrelevant if the item sits for six months, requires duplicate customer support, or gets relisted repeatedly. Add these non-fee factors:
- number and quality of matching sold comps;
- likely time to sale;
- offer and return culture;
- listing fields and photo work;
- shipping convenience and packaging risk;
- cross-listing or delisting time;
- customer-service and dispute exposure; and
- cash-flow needs.
The goal is not the lowest fee. It is the highest risk-adjusted profit per hour for the inventory you actually have.
A practical platform decision sequence
- Identify the item and condition precisely.
- Find matching completed sales on the plausible marketplaces.
- Choose an expected sale price and a floor for each.
- Run the same cost inputs through the fee comparison.
- Remove channels where the floor loses money.
- Compare demand and labor for the remaining options.
- Cross-list only when the extra reach is worth the maintenance and duplicate-sale risk.
- After the sale, record the actual payout so the next estimate improves.
Use the flip profit calculator when you need a detailed single-sale margin, and the break-even calculator when the minimum safe price is the question.
Frequently asked questions
Which selling platform has the lowest fees in 2026?
It depends on location, category, shipping method, account tier, and whether buyer-side charges affect the price. Local pickup and some buyer-fee models can have low seller-side charges, but that alone does not prove they produce the best net outcome.
Should I choose a marketplace based on fees alone?
No. Compare the achievable sale price, sell-through, shipping, returns, labor, and buyer demand. A higher-fee marketplace can produce more profit if it reaches the right buyer at a meaningfully better price.
Why does my actual payout differ from a calculator?
Common causes include category rates, buyer tax in the processing base, shipping differences, fixed order fees, optional promotion, currency conversion, fee taxes, account tiers, and limited-time programs. Treat the calculator as planning support and the order earnings statement as final.
How often should I recheck platform fees?
Before a high-value listing, after a platform announces a fee change, and whenever the actual payout stops matching the model. At minimum, review the official source pages each quarter if you sell regularly.
Bottom line
Run the same sale across the marketplaces you are genuinely willing to use. Compare the expected and floor outcomes, then let buyer demand and operational fit break close ties. That is a much better decision than chasing the smallest percentage in a headline.
