An ACH payment is an electronic bank-to-bank transfer that moves money through the Automated Clearing House network, a system that processes the vast majority of routine payments in the United States. If you’ve ever received a direct deposit paycheck, paid a utility bill from your bank account, or sent money to a friend through a payment app, you’ve used ACH. The network handles everything from payroll and tax refunds to mortgage payments and vendor invoices, processing billions of transactions each year.
How ACH Payments Work
When you make or receive an ACH payment, the money doesn’t move directly from one bank to another in real time. Instead, transactions are collected in batches and routed through the ACH network, which acts as a central clearinghouse between financial institutions. Your bank submits the payment request, the network sorts and routes it, and the receiving bank credits or debits the appropriate account.
This batch processing is what makes ACH payments inexpensive but also what makes them slower than alternatives like wire transfers. A standard ACH payment typically takes one to three business days to settle. Same-Day ACH is available for faster processing, with settlements occurring at multiple points throughout the day (1:00 p.m., 5:00 p.m., and 6:00 p.m. Eastern Time). The current limit for a single Same-Day ACH transaction is $1 million.
Wire transfers, by contrast, move money directly between banks and usually settle the same day. But they cost significantly more, often $25 to $50 per transfer, and they’re harder to reverse once sent. ACH is the better fit for routine, recurring, or lower-cost transactions where same-hour speed isn’t critical.
ACH Credits vs. ACH Debits
Every ACH transaction is either a “credit” or a “debit,” and the distinction matters because it determines who initiates the movement of money.
An ACH credit is a push transaction. The person or organization sending the money initiates the transfer, pushing funds into the recipient’s account. Direct deposit paychecks are the most common example. Your employer pushes your salary into your bank account on payday. Government payments like tax refunds and benefit deposits also work this way. You might use an ACH credit yourself when you pay a one-time bill through your bank’s online bill pay feature.
An ACH debit is a pull transaction. The recipient of the money initiates the transfer, pulling funds from the payer’s account with prior authorization. When you set up autopay for your mortgage, insurance premium, or streaming subscription, you’re authorizing the company to pull payments from your account each billing cycle. ACH debits are the backbone of recurring billing because the payee controls the timing, reducing missed payments.
What ACH Payments Cost
For consumers, most ACH payments are free. Your employer doesn’t charge you to receive direct deposit, and many banks let you send ACH transfers to other accounts at no cost. Some payment apps charge a small fee for instant transfers but offer free standard (ACH-speed) transfers.
For businesses accepting ACH payments from customers, the economics are much more favorable than credit card processing. Typical ACH processing fees range from about 0.2% to 1.25% per transaction. Many providers land between 0.5% and 1%. Some processors also charge a flat fee of $0.25 to $0.60 per transaction, while others skip the percentage entirely and charge only a flat per-transaction cost. Compare that to credit card processing fees, which commonly run 2% to 3.5%, and you can see why businesses that handle large or frequent payments prefer ACH.
Common Uses for ACH Payments
- Payroll: Most employers pay employees through ACH direct deposit rather than printing paper checks.
- Bill payments: Utilities, rent, loans, insurance, and subscriptions are frequently paid via recurring ACH debits.
- Government payments: Tax refunds, Social Security benefits, and other government disbursements typically arrive as ACH credits.
- Business-to-business payments: Companies pay suppliers and contractors through ACH to avoid the higher cost of wire transfers or the delay of mailing checks.
- Person-to-person transfers: When you send money through your bank’s transfer tool or certain payment apps using your bank account, the underlying mechanism is often ACH.
Consumer Protections and Reversals
One of ACH’s advantages over wire transfers is that transactions can be reversed. If an unauthorized or incorrect ACH payment hits your account, federal rules give you a defined process to dispute it. You have 60 days from the date your bank sends the statement showing the error to report the problem. Your notice needs to include your name, account number, and enough detail for the bank to understand what went wrong, including the type, date, and approximate amount of the error.
Once your bank receives your dispute, it has 10 business days to investigate and report back to you. If it finds an error, it must correct it within one business day. If the bank needs more time, it can extend the investigation to 45 days, but only if it provisionally credits your account within those initial 10 business days. That provisional credit means you get access to the disputed funds while the bank finishes looking into it. For new accounts (within 30 days of your first deposit), the bank gets 20 business days instead of 10 for the initial investigation.
These protections cover unauthorized transfers, incorrect amounts, transfers missing from your statement, and computational errors made by your bank. They apply broadly to electronic fund transfers, so they cover ACH debits pulled from your account without proper authorization just as they cover other electronic payment errors.
How to Send or Receive an ACH Payment
To send an ACH payment, you typically need the recipient’s bank routing number (a nine-digit code identifying their bank) and their account number. You can initiate transfers through your bank’s online portal, a mobile app, or a payment platform that supports ACH. For businesses, a payment processor or accounting platform usually handles ACH collection from customers.
To receive an ACH payment, you simply provide your routing and account numbers to the sender. For direct deposit from an employer, you’ll usually fill out a form or enter these details into a payroll portal. Some employers also ask for a voided check, which contains both numbers.
There’s no special sign-up required to use ACH. If you have a checking or savings account at a U.S. bank or credit union, your account is already capable of sending and receiving ACH transfers. The network is built into the banking system itself, which is why it remains the default method for moving money between accounts across the country.
