The Automated Clearing House was established over 40-years ago to help banks reduce the costs associated with the preferred bank transfer method of the day: paper checks. Since then, ACH has become one of the largest and most important payment systems in the world.

The costs to process ACH

As the only private-sector ACH operator,  the Federal Reserve operates the ACH system “at-cost,” meaning it re-cooperates only the money spent to run the system.

In 2015, the expenses to operate ACH were $129.9 million. The Federal Reserve’s revenue was $129.8 million (Federal Reserve System).
