Gas fee calculator
Translate gas units and gwei into an estimated network fee. Enter your own ETH price; these are example inputs.
Set your assumptions
Values shown are illustrative. Change them to explore a scenario. Inputs stay in your browser and are not sent to an exchange or wallet.
Gas fee estimate
This is a simple Ethereum execution-fee model. It does not fetch prices or gas estimates. Layer 2 data fees and other network-specific charges are excluded.
The calculation
Gas units × gas price in gwei ÷ 1,000,000,000 = ETH fee. Multiply by the ETH price for USD.
A worked example
21,000 gas × 20 gwei = 0.00042 ETH. At an example $3,000 per ETH, the modeled fee is $1.26.
