zkSync Era gas fee calculator.

Fee = gas used × base fee. Gas used depends on what the transaction does, and the base fee is the price of each unit.

The base fee is set by the protocol for every block.

zkSync Era doesn't charge the tip (priority fee): you pay the base fee alone, whatever tip your wallet offers.

zkSync Era counts the cost of publishing data to Ethereum as gas, so the same action takes two to four times the gas it does on Ethereum.

The max fee your wallet shows is only a cap. You are charged the base fee, and the rest is never spent.

Some calculators round any gas price under 0.1 gwei up to 0.1. When the gas price sits below that, their estimates come out several times too high. This one shows what the chain reports.
