What are ACH payments?

The Automated Clearing House (ACH) transfers are an electronic funds-transfer network for sending money across banks in the US. Think of it like digitizing paper checks without human involvement for B2B, government, and consumer transactions. This includes paying bills, tax refunds, delivering social security benefits, payroll, and more.

You might already use ACH transfers without realizing it—they're often called 'bank transfers,' 'direct deposits,' 'direct debits,' or 'auto-pay.' Common FinTech services like PayPal, Wise, and Venmo also use this technology.

Is Venmo considered an ACH?

Yes. Venmo facilitates standard bank transfers through the ACH (Automated Clearing House) system. When you select the regular (non-instant) option to move funds from your Venmo balance to your linked bank account, the transaction is routed via the ACH network, making it a typical ACH transfer behind the scenes.

Do banks charge ACH fees?

For individual account holders, standard ACH transfers are generally offered free of charge, especially for everyday activities like direct deposits or paying bills.

However, businesses often face fees for sending ACH payments. These can range from about $0.20 to $1.50 per transaction. Additional costs may apply for expedited (same-day) transfers, returned transactions, or chargebacks.

Why is ACH slower than wire transfers?

ACH transfers move more slowly because they are processed in groups rather than one at a time. The ACH network batches transactions and processes them during designated clearing windows throughout the day.

As a result, transfers usually take one to three business days to settle. In contrast, wire transfers are executed individually and often finalized on the same day—sometimes within minutes—since they’re processed in real time.

How does ACH payments work?

The Automated Clearing House acts as a central authority for processing bulk transfers between banks.

In the case of payroll, the company’s bank (Originating Depository Financial Institution or ODFI) sends employee payment details at regular intervals in a batch to the ACH network operator, which then distributes them to the receiving bank (Receiving Depository Financial Institution or RFDI).

The National Automated Clearing House Association (Nacha) regulates and oversees these transactions to ensure security and reliability. This makes ACH network a cost-effective option for bulk or recurring payments like payroll.

In 2023, ACH transfers moved $8.1 trillion USD, reflecting its maturity and trustworthiness as a payment method.

What is a wire transfer?

Sending money via wire transfer happens directly between sender and receiver banks. They use secured systems like Fedwire or SWIFT which facilitate information sharing for such transactions. This makes it suitable to transfer large funds in the shortest time.

There are two types of wire transfers:

1. Domestic wire transfer: Transfers funds between banks within the same country, usually within a few hours.
2. International wire transfer: Sends money between banks across different countries within 1–5 business days. You require SWIFT codes and currency conversions.

Note that the sender of a wire transfer pays a transaction fee, with no federal limits on how much banks can charge.

Is Zelle a wire transfer?

No, Zelle does not use wire transfer rails. It relies on the ACH network to facilitate payments between banks. However, because Zelle is integrated directly with many banking platforms, it often allows near-instantaneous transfers, even though it technically operates on ACH infrastructure.

How do wire transfers work?

Wire transfers move funds by sending payment instructions, not physical money. 

For example, the sender pays upfront with fees, and the sending bank uses a secure system like Fedwire or SWIFT to send payment instructions to the receiving bank. Using these instructions, the receiving bank deposits its reserve funds into the correct account number. Then, both the sender and receiving banks settle the payment on the back end.

How do I know if a transfer is ACH or wire?

To identify the type of transfer, look for clues in the transaction details or your bank statement:

ACH transfers

• Often labeled with terms like “ACH,” “Direct Deposit,” or “Electronic Payment”
• Typically take 1–3 business days unless it's a same-day ACH
• Common for routine transactions such as payroll, bill payments, or peer-to-peer platforms like Venmo and Zelle

Wire transfers

• May appear as “Wire,” “Wire Transfer,” or include specific bank routing information
• Funds usually arrive the same day, especially for domestic wires
• These transfers tend to carry higher fees and are typically irreversible

If there’s still uncertainty, your bank can verify the transfer type by checking the full transaction record.

What are the key differences between ACH transfers and wire transfers?

The difference between ACH and wire transfer depends on the financial institution involved, transaction nature, and account type. But broadly, here’s how they differ in terms of:

1. Transaction speed

How long do ACH transfers take to settle?

Since ACH transfers occur in batches (i.e. not instantaneous), standard ACH transfers may take 1-3 banking days to complete a transaction. ACH credit transactions, like payroll, get processed within 1-2 banking days. ACH debit transactions, like bill payments, take one banking day.

Some banks offer same-day ACH transfers from business to the recipient's bank, usually at additional costs.

How long do wire transfers take to settle?

Domestic wire transfers are typically completed within a few hours or the same day if done by the bank's cutoff time. Larger domestic checks and international transfers may take 1-5 business days.

2. Transaction costs

How much does ACH payment processing cost?

Many banks do not charge for ACH transfers. Even if they do, according to the AFP Payments Cost Benchmarking Survey 2022, the average cost of initiating and processing ACH payments lies around 26 cents–50 cents only.

Low costs make it suitable for processing recurring transactions like bill payments, employee payroll, or paying US contractors.

How much does a wire transfer payment cost?

Wire transfers are costly compared to ACH payments, wherein the actual cost depends on the cheque size and transaction destination.

Typically, the wire transfer fees range from $5–$50 for incoming and outgoing domestic and international wire transfers. Thus, wire transfers are fast but come with high transaction costs, making them suitable for urgent or large payments.

For international wire transfers, use the World Bank’s Remittance Price Calculator to estimate potential remittance costs by entering source and destination countries.

The additional transaction fees charged vary by bank, as there is no federal cap. This means, your total wire transfer fee will depend on your choice of bank and offers provided by them on wire transfers.

Here are examples of what some US banks charge for wire transfers as a comparison. You can observe how fees are dependent on multiple factors such as the direction of the transaction, account type, currency, and offers.

3. Security and fraud prevention

ACH and wire transfer are safe—but scammers or hackers are getting smarter. While the technologies are safe, external risks like social security number leaks in the USA increase vulnerabilities.

How secure and reversible is an ACH payment?

ACH transfers are reversible and can be stopped or canceled if the bank finds risk or the initiator wants to cancel the transaction. This happens after detailed verification and scrutiny as per Automated Clearing House’s regulations.

How secure and reversible is a wire transfer payment?

Once you send a wire transfer, it is often irreversible and difficult to retrieve funds if you make any errors. This makes it a favorite tool for scammers—for example, you may have heard of fake contests or inheritance email scams that ask the victims to wire transfer the money.

Because of this, wire transfers are subject to scrutiny from banks or authorities, requiring proof of authorization or identity documents.

4. Availability and accessibility

ACH transfers are limited to US banks and financial institutions. On the other hand, you can send remittances across the globe using wire transfers.

What are ACH transfer schedules and funds availability?

The National Automated Clearing House Association (Nacha) controls the batch processing of transactions for both sender bank (OFDI or (Originating Depository Financial Institution) and receiver bank (RDFI or Receiving Depository Financial Institution) according to the below official schedule:

You can check Nacha’s guidelines on ACH funds availability and schedule timings to align your transactions.

What are wire transfer schedules and funds availability?

Wire transfers are your best option for international payments, making it a valuable transaction infrastructure for businesses with global payrolls. The schedules and funds availability are subject to your bank's wire transfer processes.
