Enter current gas price in Gwei. Check real-time gas prices from block explorers.
21,000 for simple ETH transfers. Complex transactions require more gas.
Select transaction speed based on urgency. Faster = higher fee.
Since August 2021, Ethereum uses EIP-1559 fee structure:

Gas is the unit that measures the amount of computational effort required to execute operations on the Ethereum network. Every transaction requires gas to process, and users pay for this gas in ETH.
Total Cost = Gas Price (Gwei) × Gas Used
1 ETH = 1,000,000,000 Gwei (10⁹ Gwei)

Save on gas fees with our optimization tools and multi-chain comparison features.
Total Cost (ETH) = (Gas Price × Gas Limit) ÷ 1,000,000,000
Total Cost (USD) = [(Gas Price × Gas Limit) ÷ 1,000,000,000] × ETH Price
This calculator provides estimates only. Actual gas fees may vary based on real-time network conditions, wallet settings, and protocol changes. Always verify gas estimates in your wallet before confirming transactions.
