Real-time Ethereum gas prices in Gwei. Check current fees and pick the best time to send your transactions.
Gas fees are what you pay to execute transactions on the Ethereum network. Every action on Ethereum, whether it's sending ETH, swapping tokens on Uniswap, or minting an NFT, requires computational work. Gas is how you pay for that work.
Gas prices are measured in Gwei, which is a tiny fraction of ETH (1 Gwei = 0.000000001 ETH). When the network is busy, gas prices go up because more people are competing to get their transactions processed. When things quiet down, prices drop.
Our tracker shows three gas price tiers: Slow, Standard, and Fast. Here's what they mean in practice:
Ethereum processes a limited number of transactions per block. When demand exceeds capacity, users bid higher gas prices to get their transactions included first. This creates a dynamic market where prices can spike during popular NFT mints, DeFi events, or just heavy trading days.
Since the EIP-1559 upgrade, Ethereum uses a base fee that adjusts automatically based on network congestion, plus an optional priority fee (tip) to incentivize validators. The base fee is burned, which means high-gas-fee periods actually reduce ETH supply.
Timing matters more than most people realize. Gas prices tend to be lower during off-peak hours, which usually means late at night or early morning in US time zones (when fewer Americans are trading). Weekends also tend to be cheaper than weekdays.
Batch your transactions when possible. If you need to do multiple token approvals or swaps, some platforms let you bundle them into fewer transactions. Also consider Layer 2 networks like Arbitrum, Optimism, or Base, which process transactions off the main Ethereum chain at a fraction of the cost.
For non-urgent transactions, set a custom gas price below the current standard rate and wait. Your transaction will eventually get picked up when gas prices dip. Most wallets let you adjust gas settings manually.
The cost shown on our tracker estimates a simple ETH transfer, which uses exactly 21,000 gas units. But different operations use very different amounts of gas:
To estimate the USD cost for any transaction, multiply the gas units by the gas price in Gwei, then multiply by the current ETH price and divide by 1 billion. Or just use this tracker as a quick reference and multiply accordingly.
