An NFT’s listed price is not the amount that changes hands. Three separate costs sit around that headline number: a platform fee charged by the marketplace, creator earnings owed to the collection’s author, and gas fees paid to the blockchain’s validators. Each one is settled differently, and mixing them up is how a seller ends up surprised by what actually arrives in their wallet after a sale.
The platform fee is the marketplace’s own cut. On OpenSea it is 1% on secondary NFT sales, and because it is folded into the price displayed to buyers, it comes out of the seller’s proceeds rather than being added on top. Minting an NFT in a primary drop is priced far higher at 10%, while token swaps and private listings currently carry a 0% OpenSea fee, though a swap may still trigger charges from third-party providers. The fee is fixed at the moment a listing or an offer is created, and OpenSea says it may waive fees on certain sales at its discretion, so a listed item’s fee is settled up front rather than re-priced at settlement.
Creator earnings are a second layer and the easiest to underrate. They are a portion of the sale price paid to the original creator when an item moves from one wallet to another, and they are independent of the marketplace fee. On collections where earnings are enforced, the set percentage is paid on every sale. Where they are optional, the seller chooses how much to pass along when listing or accepting an offer, starting from the creator’s preferred rate and with no enforced minimum. A royalty is its own percentage of the price, so it can add up to more than the 1% platform fee, and it is the layer a seller has the most discretion to adjust. OpenSea’s Deals transactions, by contrast, do not include creator earnings at all.
Gas fees are the third layer and the most commonly misunderstood. They go to the validators who process the transaction, not to OpenSea, which does not set or control gas prices. The practical effect is that gas behaves differently from the other two costs. A seller pays gas when listing an NFT for the first time and when accepting an offer to sell, while other on-chain actions carry their own costs that rise and fall with the network and how congested it is at that moment. Gas is the one cost that is set by the blockchain rather than by a marketplace policy or a creator’s choice.
The cleanest way to read the three layers is by who controls each one. The platform fee is a fixed percentage the seller absorbs. Creator earnings are partly negotiable, depending on whether the collection enforces them. Gas is a network-set variable triggered by whichever on-chain actions you choose to take. Before listing or buying, add the platform fee and any royalty to the headline price, and treat gas as a separate, moving cost rather than part of the sticker. That single habit turns a confusing fee stack into three questions you can answer one at a time.
