While it doesn't cost anything to create an account with OpenSea and start browsing, there are a couple of fees you may pay when buying and selling NFTs using OpenSea.
OpenSea fee
Typically, OpenSea receives a 2.5% fee on all secondary sales and between a 2.5% and 10% fee on mints from primary drops. The seller is responsible for bearing the OpenSea fee. The buyer is responsible for paying the item price, a portion of which is received by OpenSea as its fee. All transactions and payments occur on the blockchain, at the direction of the buyer and seller, and OpenSea is not involved in payment processing.
Fees are set at the time a listing or an offer is created. If a secondary sale listing or an offer was created using OpenSea, a 2.5% fee will apply. If the listing or offer was created using OpenSea Pro, a 0.5% OpenSea fee will apply.
Deals transactions won’t include the OpenSea fee.
Creator earnings
Creator earnings refer to a portion of the NFT sale price paid to the original creator of the NFT when the item moves from wallet to wallet after a purchase. On OpenSea, creator earnings are either optional or enforced. If they’re optional, this means creators can specify their preferred creator earnings in their collection settings, but the NFT owner will ultimately choose whether to pay the suggested earnings when selling the item.
If you’re a seller, you may be responsible for paying creator earnings. If you sell an item from a collection with enforced creator earnings, you will be required to pay creator earnings. For other collections, you’ll have the option of adding creator earnings when you list an item or accept an offer. By default, these will include the creator’s preferred earnings, but you can choose to adjust this percentage. There’s no minimum creator earnings percentage enforced for items from these collections.
If you’re a buyer, you are responsible for paying the item price for the NFT. If the seller includes creator earnings in the sale, a portion of the item price you paid will go to the creator of the NFT. You can support creators by filtering for NFT listings that include creator earnings on the collection page.
Deals transactions won't include creator earnings.
Gas
Gas fees are transaction fees paid to validators on the Ethereum blockchain for processing your transaction. Gas is not paid to OpenSea, and OpenSea does not control gas prices.
If you’re a seller, you’ll pay gas when listing an item on Ethereum for the first time or accepting an offer.
Buyers will pay gas when purchasing or transferring items using OpenSea.
