How gas fees are calculated
Every Ethereum transaction pays for the work it asks the network to do. That work is measured in gas, and the price of each unit of gas is quoted in Gwei:
fee in ETH = gas used × (base fee + priority fee) × 0.000000001
The base fee is set by the network and rises or falls with demand. The priority fee is the tip you add to get picked up sooner, which is the difference between the slow, standard and fast prices above.
A worked example at today's prices: a plain ETH transfer uses 21,000 gas. At the standard price of 0.065 Gwei and ETH at $1,924, it costs $0.0026. The live Ethereum gas price on the home page shows the same numbers alongside NFT marketplace costs.
Gas fee FAQ
What is an Ethereum gas fee?
A gas fee is what you pay the Ethereum network to process a transaction. It equals the gas the transaction uses multiplied by the gas price, which is quoted in Gwei.
What is Gwei?
Gwei is the unit gas prices are quoted in. One Gwei is 0.000000001 ETH, one billionth of an ether.
Why do transactions use different amounts of gas?
Gas measures the work a transaction asks the network to do. A plain ETH transfer always uses 21,000 gas. A Uniswap swap runs far more code and typically uses around 184,500. The exact amount depends on the contract and its state, so the figures here are typical values, not guarantees.
Do I pay the full gas limit?
No. The gas limit is a cap. You pay only for the gas the transaction actually uses, at the base fee plus your priority fee. Unused gas is not charged.
How can I pay less gas?
Send when the network is quiet. In the 24 hours to November 13, 2026, the Ethereum base fee ranged from 0.04 to 2.41 Gwei, with a median of 0.13 Gwei, so timing alone moved the cost of the same transaction by about 60 times. Choosing the slow tier also helps if you are not in a hurry.
Are layer 2 networks cheaper?
Yes, by a wide margin. On November 13, 2026, a Uniswap swap cost about $0.05 in gas on Ethereum. The execution gas for the same swap was under one cent on Base, Arbitrum and Optimism, before the small data fee each rollup adds. The live Base gas price shows today's gap.
