Ethereum Gas Fee Calculator

EIP-1559 fee data plus gas units → ETH and USD cost

What is the Ethereum Gas Fee Calculator?

The Ethereum Gas Calculator multiplies operation gas units by EIP-1559 fee data to estimate ETH and USD cost. Live values prefer the site's configured own or dedicated JSON-RPC endpoint.

How do I use the Ethereum Gas Fee Calculator?

Choose ETH transfer, ERC-20, swap, NFT or custom gas units, then compare live or manual Gwei. Before executing a contract call, use wallet simulation for a more accurate gas-unit estimate.

What should I watch out for?

Complex-contract gas varies by route, token and state. The estimate does not include L2 data-publication fees or bridge-specific charges.
