Static reference estimates are calculated locally. Actual gas costs can change with network congestion and wallet settings.
Estimated Gas Fee (Standard)
Balanced fee for normal confirmation.
Network congestion, wallet priority settings, and transaction complexity may affect final cost.
Select a preset to auto-fill the Gas Used value.
Gas fee is the cost paid to validators to process and confirm your transaction.
Network congestion, demand, pending transactions, and block space availability.
Fee estimates help you choose a cheaper or faster moment to send a transaction.
Gas Fee = Gas Used x Gas Price. Example: 21,000 x 23 Gwei = 0.000483 ETH.
Choose a network, transaction type, speed, gas limit, and gas price to estimate native token and USD costs. The calculator is useful for transfers, swaps, NFT minting, bridging, and approvals.
The tracker and suggestions are static reference estimates, not live oracle data. Always confirm the final gas fee in your wallet before approving a transaction.
What formula does this use? Gas fee equals gas used multiplied by gas price in Gwei, converted from Gwei to the network token.
Why can the final wallet fee differ? Wallets may adjust priority fee, max fee, L2 costs, or gas usage based on live network conditions.
Can I use this for Polygon or Base? Yes. Pick the network and edit token price if you want a custom USD reference.
