Frequently Asked Questions
Which marketplace has the lowest seller fees?▼
It depends on your item price. For low-priced items (under $15), Mercari and eBay tend to have the lowest fees. For higher-priced items, eBay and Etsy are often more cost-effective than Poshmark's flat 20% commission.
Does Amazon charge a monthly fee?▼
Yes, Amazon charges $39.99/month for Professional sellers or $0.99 per item for Individual sellers. This calculator uses the Individual plan per-item fee for simplicity.
Are Etsy listing fees included in the calculation?▼
Yes, the calculator includes Etsy's $0.20 listing fee, 6.5% transaction fee, and payment processing fee (3% + $0.25) for a complete picture of your costs.
Why does Poshmark have a different fee structure?▼
Poshmark uses a simplified fee structure: a flat $2.95 for sales under $15, or a 20% commission for sales of $15 or more. This makes it easy to calculate but can be expensive for high-priced items.
Do these calculations include shipping costs?▼
The calculator accounts for shipping in the total order amount where applicable. Some platforms include shipping in their fee calculations while others do not.
