Ethereum Gas Fee Estimator

Estimate what an Ethereum mainnet transaction will cost in ETH and US dollars. Gas prices move constantly, so check a live gas tracker for today’s numbers.

Transaction type Typical amounts. Contracts vary, so use your wallet’s estimate when you have one.

Gas units

Base fee (gwei)Recent mainnet base fees have often been well under 1 gwei. Check a live tracker.

Priority fee, or tip (gwei, optional)

ETH price ($)

How it works

Since the 2021 London upgrade, the price per unit of gas is the base fee (set by the network and burned) plus an optional priority fee that goes to the validator. Your fee is gas units × (base fee + priority fee). One gwei is one billionth of an ETH, so we multiply by 10⁻⁹ to convert to ETH, then by the ETH price for dollars.

You’re charged for the gas a transaction actually uses, so a gas limit is a ceiling, not the final cost. This tool covers Ethereum mainnet. Layer 2 networks have their own, usually much lower, fees.

Estimates only. Actual fees depend on network demand when your transaction is included. See our disclaimer.
