Calculate Your Ethereum Transaction Fee

Use this free ETH gas fee calculator to estimate the cost of any Ethereum transaction in USD. Simply enter the gas limit for your transaction type, the current gas price in Gwei, and the current ETH price to get an instant fee estimate.

How to Use the ETH Gas Fee Calculator

The calculation is straightforward: multiply the gas units required for your transaction by the current gas price in Gwei, then convert to ETH and then to USD.

Fee in ETH = (Gas Limit × Gas Price in Gwei) ÷ 1,000,000,000

Fee in USD = Fee in ETH × ETH Price in USD

For example: A standard ETH transfer uses 21,000 gas units. At 3 Gwei and an ETH price of $2,500:

Fee = (21,000 × 3) ÷ 1,000,000,000 × $2,500 = $0.1575

Common Transaction Gas Limits

ETH Transfer: 21,000 gas units — the minimum for any ETH send transaction.

ERC20 Token Transfer: ~45,000–65,000 gas units depending on the token contract complexity.

Uniswap V3 Swap: ~130,000–200,000 gas units for a typical token swap.

NFT Mint: ~150,000–300,000 gas units depending on the contract.

Smart Contract Deployment: 500,000–2,000,000+ gas units depending on contract size.

Current ETH Gas Prices (April 2026)

As of April 2026, Ethereum gas prices frequently range between 1–5 Gwei for standard transactions. ETH fees have dropped dramatically from the 2021 peak of $53.16 per transaction to under $1 for most transfers in 2025. Layer 2 solutions like Arbitrum process transactions for under $0.03, making them ideal for frequent traders.
