Calculate Ethereum transaction gas fees in ETH and USD. Enter gas units, gas price in Gwei, and ETH price to estimate the cost of any on-chain transaction.
Added May 3, 2026
Input
21,000 for ETH transfers; 65,000–200,000 for token transfers; higher for complex contracts
Result
Enter a value for gas units (gas limit) to see your result.
Estimate Ethereum transaction costs in ETH and USD by entering gas units, gas price in Gwei, and the current ETH price. Useful for budgeting DeFi transactions before executing them.
Fee (ETH) = Gas Units × Gas Price (Gwei) × 10⁻⁹
A standard ETH transfer costs 0.00042 ETH (~$1.26) at 20 Gwei and an ETH price of $3,000.
Inputs
Result
A gas fee is the cost paid to Ethereum validators to process a transaction. It equals gas units × gas price. Gas units measure computational complexity; gas price (in Gwei) is set by supply and demand.
Gas prices spike when many users compete to have transactions included in the next block. During high-demand events (token launches, NFT mints), prices can surge 10–100× normal levels.
A plain ETH transfer always uses exactly 21,000 gas units. ERC-20 token transfers use about 65,000; Uniswap swaps typically use 100,000–200,000 depending on the pool.
