What does ACH stand for? It stands for Automated Clearing House, the electronic network that moves money between bank and credit union accounts across the United States. Your paycheck by direct deposit, the gym fee that comes out each month and the transfer you make to your own savings account at another bank usually all travel over ACH.
Instead of sending each payment one at a time, banks group them into batches and send them through the network a few times a day. That keeps costs low, which is why ACH is the standard choice for routine payments, though it is a little slower than some other methods.

What does ACH stand for, word by word?
- Automated: payments are handled by computers in files, not by paper checks passed between banks.
- Clearing: the step where banks match up who owes what before money actually changes hands.
- House: an old banking word for a central place where that matching happens. Long ago, clearing houses were real buildings where clerks swapped paper checks.
Put together, an automated clearing house is a central electronic system that sorts and settles many payments between many banks. In the US, the network is run under one shared set of rules, and the Federal Reserve is one of the operators that processes the files.
How an ACH payment moves
- Someone starts the payment. An employer sends payroll, or you sign up for autopay with a utility.
- Their bank bundles it. The bank adds the payment to a batch file with many others.
- The network sorts the batch. Payments are routed to the right receiving banks using routing numbers.
- The receiving bank posts it. The money lands in, or leaves, the account named by the account number.
There are two directions. An ACH credit pushes money into an account, like a direct deposit. An ACH debit pulls money out with your permission, like a monthly insurance bill.
On a bank statement: "ACH DEBIT CITY WATER UTIL." This means the water department pulled your bill payment from your account through the network, as you authorized.

ACH vs wire vs EFT
These three get mixed up all the time.
- EFT means electronic funds transfer. It is the broad term for any money moved electronically, so ACH is one kind of EFT.
- A wire transfer sends a single payment from bank to bank, usually within hours. Wires often cost more and are very hard to reverse once sent, which is why scammers like to ask for them.
- ACH sends payments in batches. It is usually cheaper or free, takes from the same day to a few business days, and some payments can be returned in set cases, such as an unauthorized debit.
Payments generally settle only on business days, so a transfer started on a Friday night may not post until the next week.
ACH in a sentence
- "Please send payment by ACH to the account on the invoice."
- "My paycheck hits by ACH every other Friday."
- "The ACH debit failed because the account was short."
- "Set up an ACH transfer from checking to savings."
Spoken aloud it is "A C H." On paper it takes three capitals with nothing between them. The first sound is a vowel, so the article is "an," as in "an ACH transfer." That spelled out style makes it an initialism, an idea our page on acronym vs abbreviation unpacks.
Safety tips for ACH payments
- Give your routing and account numbers only to employers, billers and people you trust.
- Check statements for ACH debits you did not approve and report them to your bank quickly.
- Be wary of an email that says a vendor changed its bank details. Call the vendor at a number you already have before you pay.
