Ethereum Gas Tracker & Bitcoin Fees
What a transaction actually costs right now, in dollars — on Ethereum and on Bitcoin. Gas is quoted in gwei and fee rates in sat/vB, neither of which tells you what you will pay, so we convert both.

Gas price bands right now
Slow / standard / fast, in gweiWhat you are actually paying
Neither "25 gwei" nor "8 sat/vB" tells you what a transaction costs. Both are prices per unit of work, and the work differs enormously between a plain transfer and a complex contract call. The table above converts both into dollars for the transaction types people actually send.
Two practical rules:
- On Ethereum, the gas limit is fixed by what you are doing. You cannot make a swap cost less gas — you can only pay less per unit by waiting for a quieter block.
- On Bitcoin, you control the size. Consolidating many small UTXOs during a cheap period genuinely reduces what you pay later, because your future transactions will carry fewer inputs.
How the dollar figures are calculated
For Ethereum:
fee in ETH = gas limit × gas price (gwei) ÷ 1,000,000,000fee in USD = fee in ETH × ETH price
Gas limits used here are the standard values: 21,000 for an ETH transfer, 65,000 for an ERC-20 transfer, 150,000 for a DEX swap and 85,000 for an NFT mint. Real transactions vary, so treat these as representative rather than exact.
For Bitcoin, mempool.space publishes recommended fee rates for four confirmation targets. We size a standard one-input, two-output SegWit transaction at 140 vB and convert at the live BTC price.
Where the data comes from
Ethereum gas prices come from Owlracle, which samples the mempool and publishes percentile-based estimates for slow, standard and fast inclusion. Bitcoin fee rates come from mempool.space. Prices for the conversion come from Binance. Everything refreshes once a minute.
Frequently asked questions
What is gas on Ethereum?
Gas is the unit that measures computational work on Ethereum. Every operation has a fixed gas cost — a plain ETH transfer is 21,000 gas, a token transfer around 65,000, a Uniswap swap 150,000 or more. What varies is the gas price, quoted in gwei (one billionth of an ETH), which is set by competition for block space. Your fee is gas used × gas price.
How do I convert gwei to dollars?
Multiply the gas limit by the gas price in gwei, divide by one billion to get ETH, then multiply by the ETH price. A 21,000-gas transfer at 20 gwei is 0.00042 ETH. We do the conversion for you in the table above for the transaction types people actually send.
What is the cheapest time to send an Ethereum transaction?
Gas follows a fairly stable weekly rhythm driven by when US and European users are awake. The quietest window is usually 00:00–06:00 UTC, and weekends are consistently cheaper than weekdays. The chart on this page shows the recent pattern, but if you are not in a hurry, setting a low max fee and waiting is far more effective than trying to time the hour.
Why are Bitcoin fees quoted in sat/vB?
Bitcoin fees are priced by transaction size in bytes, not by computation. A satoshi is one hundred-millionth of a bitcoin, and vB is a virtual byte, which accounts for the SegWit discount. A typical single-input, two-output transaction is around 140 vB, so at 10 sat/vB it costs about 1,400 satoshis. Larger transactions with many inputs cost proportionally more.
How often do these figures update?
Every 60 seconds. Ethereum gas comes from Owlracle's public endpoint and Bitcoin fee rates from mempool.space, both of which read directly from the respective mempools.
