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.

Perguntas frequentes

Respostas curtas às perguntas que os utilizadores fazem antes de confiarem no resultado.

Gas is the fee paid to blockchain validators for processing a transaction. Every operation - sending ETH, swapping tokens, or minting an NFT - consumes a fixed amount of gas units multiplied by the current gas price, which fluctuates with network congestion.

It changes constantly with network demand. The tool calculates the fee for every chain at the current gas price and highlights the cheapest one in green, so you can see the answer live at the moment you check.

No - on EVM chains the gas fee is the transaction fee. The calculator shows the total network cost in the chain native token and converts it to your selected currency.

Layer 2s like Arbitrum, Optimism, Base and zkSync settle batches back to Ethereum, so part of your fee pays for posting that data on Layer 1. The gas price returned by their nodes already includes this L1 cost, so the estimate stays accurate.

Gas prices are fetched live from public RPC nodes and token prices from public market APIs, both refreshed every 60 seconds. Fees are estimates - the exact fee can vary by a few percent depending on network congestion and wallet settings.
