About ETH Gas Estimator
Webbeat’s ETH Gas Estimator is the quickest way to judge your real-time Ethereum transaction fees before you submit a swap, NFT mint, transfer, or any smart contract action. Optimized for both beginners and experts, the tool calculates the final cost in both ETH and USD so you can plan confidently and reduce wasted crypto.
Main Uses
- Estimate the total fee of any Ethereum transaction in both ETH and USD
- Get instant results by inputting gas units, gas price, and current ETH/USD rate
- Check costs for simple transfers (21,000 gas) or complex contract calls (hundreds of thousands of gas units)
- Works for any EVM chain (Polygon, BNB Chain, Arbitrum, etc.) — just enter accurate live chain values
How Does Ethereum Gas Work?
- Gas Units: Every smart contract operation needs a certain number of gas units, set by the core protocol
- Gas Price: The gwei value you set as a tip to miners/validators, set by market demand. Blocks clear higher-price, more urgent transactions first
- ETH Price: Market price for ETH in USD — plug in the latest value for accurate conversion
- Formula:
(gas units × gas price in gwei × 0.000000001) ETH × ETH price (USD)for total fee in dollars
Why This Tool Is Useful
- Helps you spot high gas periods to avoid overpaying
- Great for tracking contract deployment, swaps, or batch actions that use more gas
- Works offline and is fully anonymous — no tracking, no data saved
- Lets you experiment with different scenarios to optimize your fees
Pro Tips
- Open Etherscan or your wallet before sending — copy the real current “base” and “priority” gas price
- Complex actions like NFT mints or DeFi staking can use 80,000–200,000+ gas units
- Check ETH price updates right before sending, as a big move can increase final cost
- This calculator is for single transactions — for batch or multi-step costs, run calculations multiple times with each parameter
