What is the ZEC transaction fee?

Could you elaborate on the transaction fee associated with Zcash, or ZEC? I'm curious to understand how it differs from other cryptocurrencies and what factors influence its determination. Does the ZEC transaction fee vary depending on the complexity of the transaction, the current network congestion, or any other variables? Additionally, how does Zcash's privacy-enhancing features impact the transaction fee? Understanding these details would help me make informed decisions when considering using ZEC for my financial transactions.
