The ETH gas fee is the payment you make to the Ethereum network for every transaction — whether you are sending ETH, swapping tokens, or using a DeFi app. Gas fees are paid in gwei (a tiny fraction of ETH) and fluctuate constantly based on network congestion. This free ETH gas fee calculator helps you estimate the cost of a transfer, token swap, or NFT mint before you confirm.
How ETH Gas Fees Are Calculated
Your total gas fee = gas units used × gas price (gwei). A standard ETH transfer uses about 21,000 gas units, while complex smart-contract interactions use far more. When the network is busy, the gas price rises and fees spike — this is why a simple transfer can cost $1 one hour and $20 the next.
How to Use This ETH Gas Fee Calculator
- Enter the current gas price in gwei (check a live tracker if unsure).
- Enter the gas units your transaction will use (21,000 for a simple ETH transfer).
- Click Calculate to see the estimated fee in ETH and USD.
