How much does it cost to swap ETH to BNB?

Can you please clarify the current cost associated with exchanging Ethereum (ETH) to Binance Coin (BNB)? I'm interested in knowing the specific rate or range of fees that one might encounter when making this type of transaction. Additionally, is there a way to minimize these costs, perhaps by using a particular exchange platform or by considering market conditions at the time of the swap? Thank you for your assistance in providing this information.
