What is a bank transfer? Everything you need to know

A bank transfer is one of the most common ways to move money — yet many people aren't sure exactly how it works or what types exist.

Whether you're paying rent, splitting expenses, or sending money abroad, understanding bank transfers can help you save time and money.

Moving your money should be a simple, no-stress experience that fits into your digital lifestyle. Read on to learn how.

What is a bank transfer?

At its simplest, a bank transfer is the movement of money from one bank account to another. Because the process is digital, there's no need for physical cash or paper checks to change hands. You can send a bank transfer between your own separate accounts, or you can send money to another person or a business.

In the US, the term is often used as a broad category that includes several different systems, such as ACH and wire transfers. While the end result is the same — money leaves one account and arrives in another — the speed, cost, and technology used behind the scenes vary significantly.

How bank transfers work: Push vs pull

To understand what a bank transferis, it helps to look at the direction the money moves. Transfers generally fall into 2 categories: those where you 'push' the money our and those where a third party 'pulls' it in.

Bank credit transfers (push)

A bank credit transfer occurs when you instruct your financial institution to send money to another account. You're 'pushing' the money from your balance to the recipient. This is common when you use an app to pay a friend back for dinner or when you pay a bill manually through your online banking portal. You control exactly when the money leaves and how much is sent.

Bank debit transfers (pull)

A bank debit transfer happens when you give a company permission to take money from your account. The recipient initiates the transaction to 'pull' the money. A common example is an automated monthly payment for a utility bill or a gym membership. In these cases, you provide your account and routing numbers once, and the business handles the rest on the agreed dates.

Types of domestic bank transfers in the US

Domestic transfers move money between financial institutions within the US. There are 2 primary networks used for these transactions: the Automated Clearing House (ACH) and the wire transfer networks.

ACH transfers

The ACH network is the backbone of the US financial system. It's managed by Nacha, an organization that sets the rules for how electronic payments move. ACH transfers are usually batched together and processed at specific times throughout the business day.

There are 2 main types of ACH transactions:

1. Direct deposit: This is an ACH credit where an employer or government agency sends money to your account.
2. Direct payment: This is an ACH debit used to pay bills or move money between personal accounts at different banks.

Because ACH transfers are processed in batches, they're efficient and often cost nothing for personal customers. However, this batching process means they don't always go through right away.

Wire transfers

A wire transfer is a more direct way to send money. Unlike ACH, wire transfers are processed individually and in real-time (or near real-time). In the US, domestic wires usually move through the Fedwire Funds Service, which is operated by the Federal Reserve.

Wire transfers are designed for speed and certainty. Once a wire is sent, it's generally considered cleared money and can't easily be reversed. This makes them the preferred choice for large, urgent transactions, such as a down payment on a home. However, this premium service typically comes with a higher fee than a standard electronic bank transfer.

International bank transfers

When you need to send money across borders, the process becomes slightly more complex. Domestic systems like ACH don't operate outside the US, so banks need to use international networks to communicate.

The SWIFT network

The Society for Worldwide Interbank Financial Telecommunication (SWIFT) is the most common network for international transfers. It acts as a secure messaging system that tells banks where to credit money. Because your money might pass through several intermediary banks before reaching its destination, international transfers can take longer and involve additional fees.

At Revolut, we aim to make this process clearer. We use local payment networks where possible to help your money arrive faster and with fewer hidden costs. If you're planning a large move, you should also check the international wire transfer limit to make sure you're compliant with federal reporting rules.

Regional systems

Different parts of the world have their own local bank transfer equivalents. For example:

• The Single Euro Payments Area (SEPA): This allows for easy transfers between European banks.
• CHAPS/Bacs: Systems used specifically within the UK for payments in pounds.

How long do bank transfers take?

Bank transfer times depend heavily on the network used and the time of day the request is made. Let's break it down:

• ACH transfers: These typically take 1–3 business days. While same-day ACH is becoming more common, many banks still follow the traditional multi-day timeline.
• Domestic wire transfers: These are often completed within 24 hours, provided the request is made before the bank's cut-off time.
• International transfers: Moving money abroad via SWIFT usually takes 1–5 business days, depending on the destination and the number of intermediary banks involved.

Remember that business days don't include weekends or federal holidays. If you initiate a transfer on a Friday evening, the process might not begin until the following Monday morning.

If you need the money to arrive immediately, try a Revolut-to-Revolut transfer. This method allows you to send money to friends who are also on Revolut. It costs nothing and will arrive in their account immediately.

Understanding the costs and fees

There are several types of charges you might face when you make a bank transfer. These include the following:

• Outgoing fees: Your bank may charge you a fee to send a wire, which can range from $15–50 for domestic transfers and more for international ones.
• Incoming fees: Some financial institutions charge a small fee just for you to receive a wire transfer.
• Exchange rate margins: For international transfers, banks often add a mark-up to the exchange rate, which means you'll pay more than the rate you see on Google.
• Intermediary fees: On the SWIFT network, intermediary banks may take a cut of the total amount.

Standard ACH transfers often cost nothing for personal customers, making them the most cost-effective way to handle routine payments.

Are bank transfers safe?

Bank transfers are generally safe. Financial institutions use advanced encryption and identity verification to protect your money. However, because transfers, especially wires, are difficult to reverse, they're a common target for scammers.

To stay safe, you should:

• Verify the recipient: Only send money to people or businesses you know and trust.
• Double-check the details: A single digit error in an account or routing number can lead to your money being sent to the wrong place.
• Be wary of urgency: Scammers often create a sense of panic to trick you into wiring money quickly.
