What Electronic Funds Transfer Is

Electronic Funds Transfer (EFT) is any movement of money from one bank account to another using electronic systems instead of paper checks or cash. Wire transfers are one type of EFT, but the category is much broader. It includes ACH transfers (the system that handles most routine bank-to-bank payments), debit card transactions, direct deposit of your paycheck, automatic bill payments, and transfers between your own accounts at different banks.

The key difference between EFT and wire transfer is speed and cost. Wire transfers move money the same day or next business day and cost $15 to $50 per transfer. Most other EFTs take one to three business days and are free or cost a few dollars. Wire transfers are designed for urgent or large payments. Other EFTs handle everyday money movement.

When you use EFT, you are sending instructions through a network — not physically moving anything. The sending bank and receiving bank communicate electronically, verify the account numbers, and move the funds. Your money stays in the banking system the entire time.

Key Takeaways

  • Electronic Funds Transfer is a category that includes wire transfers, ACH transfers, direct deposit, and automatic bill payments — any electronic movement of money between accounts.
  • ACH transfers, the most common non-wire EFT, take one to three business days and are usually free, making them suitable for routine payments.
  • Wire transfers are a faster, more expensive type of EFT used when you need money to arrive the same or next business day.
  • EFT transactions require accurate account and routing numbers; mistakes can send money to the wrong account, and recovery is difficult.
  • Banks limit how many free EFTs you can make per month from savings accounts, though checking accounts typically have no limit.

How ACH Transfers Differ from Wire Transfers

ACH stands for Automated Clearing House, a network that processes routine electronic payments. The Federal Reserve and The Clearing House operate the two main ACH networks in the United States. When you set up direct deposit, pay a bill online, or transfer money between your own accounts at different banks, you are usually using ACH.

ACH transfers batch payments together and process them in cycles throughout the day. This batching is why they take longer — your transfer might sit in a queue for several hours before the next processing window. Most ACH transfers clear within one to three business days. The sending bank and receiving bank do not communicate in real time the way they do with wire transfers.

Because ACH is slower and handles smaller, routine payments, it costs less. Most banks offer ACH transfers free to their customers. Some banks charge $1 to $3 per transfer if you exceed a monthly limit (often 6 free transfers per month from savings accounts). Wire transfers, by contrast, cost $15 to $50 because they move money when ready and require manual processing by bank staff.

ACH transfers also have lower per-transaction limits than wire transfers. Many banks cap ACH transfers at $10,000 to $25,000 per day, though you can request a higher limit. Wire transfers often allow $50,000 or more in a single transaction.

Other Types of Electronic Funds Transfer

Direct deposit is an EFT where your employer or a government agency (such as Social Security) sends your payment directly to your bank account instead of issuing a check. The payer initiates the transfer using your routing number and account number. Direct deposit is free and typically arrives on a set schedule — payday for employment, the first or third of the month for benefits.

Automatic bill payments are EFTs you set up to pay recurring bills like utilities, insurance, or loan payments. You authorize your bank to send money to the biller on a schedule you choose. These are usually free and take one to three business days to process. If you set up the payment through the biller's website rather than your bank, the biller may use ACH or a different system.

Debit card transactions are EFTs that happen when ready or within hours. When you swipe a debit card or enter your card number online, the merchant's bank requests the funds from your bank. The money leaves your account when ready, though it may take a day or two to appear as a deduction on your statement.

Transfers between your own accounts at different banks are EFTs you initiate through your bank's website or app. These typically use ACH and take one to three business days. Some banks offer faster transfers for an extra fee, or they may move the money the same day if both accounts are at banks in the same network.

What Information You Need to Send Money via EFT

To send an ACH transfer or wire transfer, you need the recipient's routing number and account number. The routing number identifies the bank; the account number identifies the specific account within that bank. For wire transfers, you may also need the recipient's full name, address, and sometimes a reference code or SWIFT number if the money is going to a bank outside the United States.

You can find your own routing number on the bottom left of a check, on your bank's website, or by calling the bank. The account number appears on the check as well, or in your online banking portal. If you are sending money to someone else, ask them for both numbers in writing — do not rely on verbal instructions, which are straightforward to mishear.

Double-check the numbers before you confirm the transfer. If you send money to a wrong account number, the receiving bank may reject it and return it to you within a few business days. But if the account number is valid (even if it belongs to the wrong person), the money will go there, and recovering it is difficult and slow. The receiving bank is not required to reverse a transfer based on a mistake in the account number.

Limits and Restrictions on EFT Transactions

Banks impose transaction limits on EFTs for fraud prevention and regulatory reasons. Savings accounts typically allow six free EFTs per month (including ACH transfers, automatic bill payments, and transfers to other banks). Once you exceed six, the bank may charge a fee per transaction or move the account to a checking account. Checking accounts usually have no limit on EFTs.

Individual transfers also have limits. ACH transfers are often capped at $10,000 to $25,000 per transaction, though you can request an increase. Wire transfers may allow $50,000 or more per transaction, but the bank may require additional verification for very large amounts. Debit card transactions are usually limited to $500 to $2,500 per day, depending on the bank and the merchant.

These limits exist to protect you from fraud and to comply with banking regulations. If you need to move more money than the limit allows, you can make multiple transfers on different days, request a higher limit from your bank, or use a different method such as a cashier's check.

How Long EFT Transactions Take

The time an EFT takes depends on the type and the banks involved. ACH transfers typically take one to three business days. The sending bank submits the transfer during a processing window, it sits in the ACH network queue, and the receiving bank posts it to the account. Weekends and bank holidays add time — a transfer initiated on Friday may not arrive until Tuesday.

Wire transfers move the same business day if initiated before the bank's cutoff time (usually 2 p.m. or 3 p.m. local time). If you initiate a wire after the cutoff, it processes the next business day. International wire transfers may take one to three business days depending on the receiving country and bank.

Direct deposit arrives on a set schedule determined by the payer. Employers typically deposit paychecks one to two days before payday. Government benefits arrive on a set date each month. Automatic bill payments are scheduled by you and typically process one to three business days before the due date you choose.

Debit card transactions are authorized when ready, but the money may not leave your account for one to two business days. The merchant's bank requests the funds when ready, but the actual transfer through the ACH network takes time. Your bank may show the transaction as "pending" during this period.

Security and Fraud Protection for EFT

EFTs are generally find because they require account and routing numbers, which are harder to guess than a name and address. However, if someone obtains your account number, they can initiate an unauthorized ACH transfer from your account. Banks are required to investigate unauthorized transfers and refund your money if the transfer was not authorized by you.

To protect yourself, do not share your account number with people you do not trust. When you receive a request for your account number, verify that the request is coming from a legitimate source — call the organization directly using a phone number from their official website, not from an email or text message. Scammers often pose as banks or government agencies to obtain account information.

If you notice an unauthorized EFT on your account, contact your bank when ready. Federal law requires banks to refund unauthorized ACH transfers if you report them within 60 days. Wire transfers have less protection — once the money leaves your account, recovery is difficult. This is one reason wire transfers are riskier for large payments to people you do not know well.

Frequently Asked Questions

Can I cancel an EFT after I send it?

It depends on the type. ACH transfers can usually be canceled if you contact your bank before the transfer processes, which is typically within one business day. Wire transfers cannot be canceled once they leave your bank — the money is already in transit. Contact your bank when ready if you need to cancel; do not wait.

What happens if I use the wrong account number?

If the account number is invalid, the receiving bank rejects the transfer and the money returns to you within a few business days. If the account number is valid but belongs to the wrong person, the money goes to that account, and recovery requires the receiving bank to reverse the transfer — which they are not required to do. Always verify the account number in writing before sending.

Why does my bank limit EFTs from my savings account?

Federal Regulation D historically limited savings account withdrawals to six per month to encourage people to save rather than spend. Although the regulation was relaxed in 2020, many banks still enforce the limit or charge fees for transfers beyond six per month. Checking accounts have no such limit.

Is EFT the same as a wire transfer?

No. Wire transfer is one type of EFT. EFT is the broad category of all electronic money movement, including ACH transfers, direct deposit, automatic bill payments, and debit card transactions. Wire transfers are faster and more expensive than most other EFTs.

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

Your bank's website or app will tell you. When you initiate a transfer, the bank shows you the type and the expected arrival time. ACH transfers show one to three business days; wire transfers show same-day or next-day delivery. The fee also indicates the type — ACH is usually free or a few dollars, while wire transfers cost $15 to $50.
