Platform fees are the silent profit killer in reselling. Most sellers know their buy price and sell price — but don’t know how much each platform takes, how that compounds across a year, or how drastically fees vary between platforms for the same item. This is the complete picture.
Fee Comparison Table: What You Actually Net on a $50 Sale
| Platform | Fee Structure | Fee on $50 | You Receive | Net % |
|---|---|---|---|---|
| Vinted | 0% seller fee | $0.00 | $50.00 | 100% |
| Whatnot | 8% | $4.00 | $46.00 | 92% |
| Grailed | 9% | $4.50 | $45.50 | 91% |
| Etsy | 6.5% + $0.20 + ~3% payment | ~$5.20 | $44.80 | 90% |
| Mercari | 10% | $5.00 | $45.00 | 90% |
| Depop | 10% + ~2.9% + $0.30 processing | ~$6.75 | $43.25 | 87% |
| eBay | ~12.9% + $0.30 | ~$6.75 | $43.25 | 87% |
| Facebook Marketplace | 5% shipped / $0.40 flat local | ~$2.50 (shipped) | $47.50 | 95% |
| Poshmark | 20% over $15 / $2.95 flat under $15 | $10.00 | $40.00 | 80% |

The Annual Impact of Fee Differences
These percentage differences compound enormously at scale. Consider a seller doing $30,000 in gross sales per year:
| Platform | Gross Revenue | Fees Paid | Net Revenue |
|---|---|---|---|
| Vinted | $30,000 | $0 | $30,000 |
| Grailed | $30,000 | $2,700 | $27,300 |
| Mercari | $30,000 | $3,000 | $27,000 |
| eBay | $30,000 | $3,870 | $26,130 |
| Poshmark | $30,000 | $6,000 | $24,000 |
A reseller using Poshmark exclusively leaves $6,000 on the table compared to Vinted — on the same $30,000 in gross sales. That’s $500/month in platform fees that could be margin.
Understanding Each Platform’s Fee Structure
Vinted — The Fee-Free Model
Vinted charges sellers zero fees. Instead, buyers pay a buyer protection fee (roughly 3-8% of the item price) on top of the listed price. This is a transparent cost to buyers — they see it before checkout.
The result: you list at $30, you receive $30. No math required.
Poshmark — The Highest Fees, With a Trade-Off
Poshmark’s 20% is the highest fee of any major platform. On a $15+ item, Poshmark takes a full 20%. Under $15, it’s a flat $2.95.
The trade-off: Poshmark provides a prepaid USPS shipping label to buyers (capped weight), which simplifies the buyer experience and may justify higher item prices. Poshmark’s social features also drive organic discovery you don’t get on search-only platforms.
The calculus: Poshmark can still be worth it for the right categories, but it should never be your only platform.
eBay — Volume Justifies the Fee
eBay’s ~12.9% fee (plus $0.30 per order) is mid-range, but the platform’s 135M+ active buyer base means higher sell-through rates that offset the fee cost. A $50 item that sits for 6 months on Poshmark and sells in 1 week on eBay is better on eBay, even with the higher fee.
eBay also charges a $0.35 listing fee after your first 250 free monthly listings.
Depop — The Instagram Tax
Depop’s 10% fee plus payment processing (~2.9% + $0.30) results in an effective ~13% take on most items. For a platform targeting younger buyers with lower price expectations, this can squeeze margin.
Mitigation: sell items with strong aesthetic cache (vintage, Y2K, streetwear) where Depop buyers will pay a genuine premium not available elsewhere.
Mercari — The Clean 10%
Mercari’s flat 10% fee is simple and competitive. No listing fees, no payment processing surcharge baked in. One of the more seller-friendly fee structures on the market.
Grailed — Luxury Margin Preservation
Grailed’s 9% fee is one of the lowest, and it serves a higher-value buyer pool (men’s designer, luxury streetwear). The combination of low fees and high average sale prices makes Grailed extremely efficient per item listed.
How to Use Fee Differences Strategically
The optimal strategy isn’t to avoid platforms with higher fees — it’s to price differently on each platform to protect your margin.
- On Poshmark (20%), price 12-15% higher than your eBay price for the same item
- On Vinted (0%), price slightly below your eBay price and still net more
- On Grailed (9%), match eBay pricing and net slightly more per sale
BlastLister lets you set platform-specific pricing on a single listing — so your Poshmark price is automatically higher than your Vinted price, even though it’s one listing.
The Takeaway
Fee optimization is free money. The same item sold on Vinted nets 25% more than Poshmark. Routing even 20% of your sales through lower-fee platforms meaningfully improves your annual margin.
The best resellers don’t choose one platform — they list everywhere and let buyers on each platform find them.
