Ethereum's transaction fees continue to fluctuate, but they haven't changed much since proof of stake rolled out; the update was not intended to change fees.

The gas fee is calculated using Gas Limit * Gas Price per Unit. So if the gas limit was 100,000 and the price per unit was 200 gwei, the calculation would be 100,000 * 200 = 20,000,000 gwei or 0.02 ETH.

Gas limit is the maximum amount of work you're estimating a validator will do on a particular transaction. A higher gas limit usually means the user believes the transaction will require more work. Gas price is the price per unit of work done. So, a transaction cost is the gas limit multiplied by the gas price.

Many transactions also include tips, which are added to the gas price (the more you pay, the faster your transaction is completed). The lower a user estimates their gas limit, the lower the priority in the queue they will be.

But in general, for a simple ERC20 token transfer (for example USDT) into only one address and with no extra data or additional function calls, the transaction fee may be as low as 2 USD when the network is quiet or as high as 100 USD or even more when the network is crowded!
