Crypto Gas Fee Calculator

How to Use This Tool

Select your local currency, pick a common transaction type such as an ETH transfer (21,000 gas) or ERC-20 transfer (65,000 gas), choose a transaction speed (Standard, Fast or Instant), and the table updates instantly with the estimated fee for every supported chain.

Features

• 14 EVM chains - Ethereum, Arbitrum One, Optimism, Base, zkSync Era, Linea, Scroll, BNB Smart Chain, Avalanche, Polygon, Gnosis, Celo, Fantom and Harmony.
• Live gas prices - Gas prices are fetched directly from each chain via public RPC nodes and cached for 60 seconds. If a node is unreachable, the tool falls back to cached values and marks the row accordingly.
• Real token prices - ETH, BNB, AVAX, POL and the rest are converted from live USD market prices into 20+ fiat currencies.
• Cheapest chain highlighted - The most affordable network for your exact transaction is marked green and shown in the summary card.
• Flexible inputs - Standard transaction presets or a fully custom gas amount, plus Standard / Fast / Instant speed tiers.
• Sort and export - Sort by fee, gas price or chain name, filter by layer or search, and export the full table as CSV.

Understanding the Numbers

Fee = Gas Used x Gas Price (gwei) x 10^-9 x Token Price (USD) x Exchange Rate. The gas price is read live from each chain and multiplied for the Fast (1.5x) and Instant (2x) tiers. Layer 2 networks such as Arbitrum and Optimism also bundle their Layer 1 data posting costs into the gas price returned by the node, so the estimate reflects real user cost.
