How much does an ACH cost a bank?

In the realm of financial services, the Automated Clearing House (ACH) network serves as a critical infrastructure for facilitating electronic transactions. But how much does it actually cost a bank to utilize this system? The cost of ACH transactions for banks can vary depending on several factors, including the type of transaction, the volume of transactions processed, and any additional fees levied by third-party service providers. It's crucial for banks to carefully analyze the costs associated with ACH to ensure they are operating efficiently and profitably. As a questioner delving into this matter, I'd like to know: Does the cost vary significantly between different types of ACH transactions? Are there any hidden fees or additional costs that banks should be aware of? And ultimately, how do banks balance the benefits of ACH with the associated costs?
