Cost on Ethereum L1
$11.25
Approx. on an L2
$0.34
That is a steep $11.25 on mainnet. The identical action on a Layer 2 like Arbitrum or Base would cost roughly $0.34, which is why most everyday activity has moved to L2s.
How this is calculated
fee (ETH) = gasPrice (gwei) x gasUnits / 1,000,000,000; fee (USD) = fee (ETH) x ETH price
- Gas units are typical values per action; the exact number varies by contract.
- The Layer 2 figure is an approximate 3% of the L1 cost, shown only for scale. Real L2 fees vary with L1 data costs.
- Enter the ETH price manually so the tool works offline and stays accurate.
