Frequently Asked Questions
What is a marketplace selling fee?
The referral percentage plus any fixed closing fee taken per sale. At $45 with 15% referral and $1.80 closing, the selling fee is $8.55 per unit.
Referral fee vs closing fee?
Referral is a percent of price (category-based); closing is a fixed per-unit amount (common in media and grocery). Cheap units feel closing fees most.
Do selling fees include payment processing?
Marketplace referral figures usually exclude separate payment or service fees — add 2-3% plus fixed micropayment amounts for true per-sale cost.
How do I compare fee loads across SKUs?
Use fee share of price: identical referral rates burden cheap SKUs more once fixed fees land. Bundle sub-$15 items to dilute fixed fees.
Can selling fees change?
Yes — marketplaces adjust category rates yearly. Re-run fee math each Q4 and after every fee announcement; grandfathered assumptions silently rot margins.
