How much does MetaMask transfer cost?

The total cost of transferring funds through MetaMask can vary depending on several factors. When using the 'Sell' function to convert crypto to fiat and transfer to a bank account, users may encounter various fees such as gas fees, chain exchange fees, and additional costs charged by partner service providers like MoonPay. In one example, a user transferring 0.05 ETH incurred total fees of approximately 9%, including a 1% chain exchange fee, an ETH gas fee, and other implicit costs. Therefore, the transfer cost through MetaMask can be significant and should be carefully considered.
