Gas Used vs Gas Price
About the Ethereum Gas Calculator
Transaction cost is gas used × gas price. Gas measures computational work (a simple transfer: 21,000 units); price is quoted in gwei, one billionth of an ETH. At 25 gwei and $3,000 ETH, a transfer costs 525,000 gwei = 0.000525 ETH ≈ $1.58.
Static Price Note
ETH price moves constantly, so this calculator treats it as a user-entered value — set it to today's market rate for an estimate. Gas price similarly fluctuates with network congestion; at busy times a "fast" transaction costs several times more gwei.
