Ethereum Gas Fee Estimator – Calculate ETH Transaction Costs Accurately

Paying too much in gas fees? Missing transaction deadlines? You're not alone.

Our Ethereum Gas Fee Estimator helps you calculate exactly how much ETH you’ll pay for any transaction — whether sending tokens, swapping on Uniswap, or interacting with smart contracts — so you can choose the right fee level and avoid waste.

What Is Ethereum Gas?

Gas is the fee required to execute any action on the Ethereum network. It's paid in ETH and covers the computational energy needed to process and validate transactions.

Two key components:

  • Gas Limit: Maximum units of gas you’re willing to spend (e.g., 21,000 for simple send)
  • Gas Price: How much you pay per unit of gas (in Gwei: 1 Gwei = 0.000000001 ETH)

Total Cost = Gas Limit × Gas Price

Why Accurate Gas Estimation Saves You Money

During high congestion (e.g., NFT mints, market volatility), gas prices can spike from 20 Gwei to 200+ Gwei — making the same transaction 10x more expensive.

This tool uses real-time data from Etherscan and CoinMarketCap to show:

  • Low: Cheaper, slower confirmation (ideal for non-urgent sends)
  • Medium: Balanced speed and cost (recommended for most swaps)
  • High: Fastest processing (use during NFT drops or urgent trades)

Gas Estimates for Common Transactions

  • ETH Transfer: ~21,000 gas
  • ERC-20 Token Transfer: ~50,000–70,000 gas
  • Uniswap Swap: ~100,000–150,000 gas
  • NFT Mint: Varies widely (check project docs)
Pro Insight: Schedule non-urgent transactions during low-traffic hours (UTC 00:00–04:00) when gas fees are often 50–70% lower.

Frequently Asked Questions (FAQ)

Get quick answers about Ethereum gas fees and transaction costs

⛽ What is an Ethereum gas fee?

A gas fee is the cost paid in ETH to process any transaction or smart contract interaction on the Ethereum network.

📉 Can I reduce my gas fees?

Yes! Choose “Low” priority in wallets like MetaMask during off-peak hours. Avoid peak times like NFT mints or major news events.

⏱️ How long does a transaction take at different gas levels?

Low (10–20 Gwei): 2–10 minutes
Medium (30–50 Gwei): 30 seconds – 2 minutes
High (60+ Gwei): Under 30 seconds (priority mining)

📱 Does this work on mobile?

Yes, fully responsive design works perfectly on smartphones and tablets — ideal for checking fees before signing transactions.

🔁 Can I change gas after sending?

Yes, using “Speed Up” or “Cancel” in MetaMask if the transaction is still pending. Otherwise, no — once confirmed, it’s final.

🌐 Are gas fees the same on Polygon or BSC?

No. Polygon, BSC, and Arbitrum have their own fee structures. This tool is for Ethereum Mainnet only.

🔐 Is my wallet data safe?

Yes. This estimator doesn’t connect to your wallet or access private keys. It only calculates estimated costs based on current network data.
