NFT Gas Calculator

A mint writes new storage: the token's owner, the holder's balance and often a counter or metadata. Writing a fresh storage slot is one of the most expensive operations in the Ethereum virtual machine, so a mint commonly lands well above the roughly 65,000 gas of a plain ERC-721 transfer.

Before a marketplace can move your NFT when it sells, you grant its contract permission with setApprovalForAll. That costs gas once per collection per marketplace, around 46,000 gas, and later listings in the same collection are usually signed off-chain for nothing.

Block explorers and wallet apps show a gas tracker with the latest base fee in gwei. It changes every block, by up to 12.5 percent, depending on how full the previous block was, so a figure from an hour ago can be well off during a hyped drop.

On a quiet network one or two gwei usually gets a transaction into the next few blocks. In a competitive mint, bidders raise the tip to get ahead, and that can push the total price per gas many times above the base fee.

Yes. If a mint reverts, for example because the supply sold out while your transaction waited, the gas consumed up to that point is still charged. Only the mint price is returned, because the transfer of value never completed.

In the United States the IRS treats NFTs as digital assets, and fees paid to acquire or dispose of one generally adjust its cost basis or proceeds. Keep the ETH and dollar figures from each transaction for your records and check the IRS digital asset guidance.
