Wrap ETH to WETH Gas Fee: Live Cost
Right now, to wrap ETH into WETH on Ethereum mainnet costs about $0.0093 at the standard gas price of 0.081 gwei.
WETH is ETH wrapped as an ERC-20 token so that it can be used by contracts that expect tokens. Wrapping deposits ETH into the WETH contract and uses roughly 30,000 to 46,000 gas. Unwrapping costs about the same.
How the cost is calculated
Fee = gas used × gas price × ETH price. With the current standard price: 46,000 gas × 0.081 gwei = 0.00000372 ETH, which is $0.0093 at $2,492 per ETH. Across the typical range of about 30,000 to 46,000 gas, the standard cost is between $0.0060 and $0.0093.
How to pay less
- Most DEX routers wrap and unwrap automatically inside a swap, so you rarely need to do it separately.
- Check the cheapest hours to transact and avoid known demand spikes.
