About Gas Fees
Gas fees compensate validators for processing transactions. Layer 2 chains like Base and Arbitrum dramatically reduce fees by batching transactions to Ethereum mainnet. Cosmos SDK chains like TX Blockchain use a different fee model with flat gas prices. All figures shown are educational estimates using average prices.

About This Tool
Gas Estimator is a free browser-based tool that calculates estimated transaction fees for Ethereum and EVM-compatible blockchains. It helps developers, traders, and DeFi users understand the cost of on-chain operations before submitting transactions.
Enter the current gas price (in Gwei) and the gas limit for your operation — such as a simple ETH transfer, ERC-20 swap, or smart contract interaction — and the tool calculates the estimated fee in ETH and its USD equivalent. You can adjust parameters to model different network congestion scenarios.
Use it before executing DeFi trades, NFT mints, or contract deployments to avoid overpaying or running out of gas. Everything runs in the browser with no wallet connection or signup required.
