Frequently asked questions
OpenSea NFT Fee Calculator — 1% Marketplace Fee
Estimate NFT sale proceeds after OpenSea's current 1% marketplace fee. Choose a network to see the difference between variable Ethereum gas and a small Polygon planning estimate; creator earnings remain separate.
Current 1% marketplace fee
Uses the fee shown in OpenSea's current help documentation.
Network-aware estimate
Keeps Ethereum gas variable and shows only a small Polygon planning estimate.
Creator earnings separated
Does not assume one royalty percentage when collection rules can differ.
Worked example: a $1,500 NFT sale
The 1% marketplace fee is $15 on a $1,500 sale. Ethereum gas is left variable because it depends on the network at signing time; the Polygon option adds only the small planning estimate shown in the calculator.
Before creator earnings: $1,485 on Ethereum before gas, or about $1,484.99 using the Polygon planning estimate.

Ethereum network fees can change between listing, acceptance, and final signing.

OpenSea fees, creator-earnings settings, and network costs can change. Review the transaction prompt and current help documentation before signing a sale.
