ACH vs. wire transfer: How to choose the best option

When you need to send money electronically, two main options often come up: ACH transfers and wire transfers. While both are safe and widely accepted, their differences can make one a better fit than the other depending on your needs. In this guide, we’ll break down what each method is, how they work, and when to use them.

What is an ACH transfer?

An Automated Clearing House (ACH) transfer is an electronic payment sent through a network that connects banks and credit unions across the U.S.

• Payroll direct deposits, like your paycheck going straight into your bank account

• Automatic bill payments, like utilities or subscriptions

• Person-to-person transfers through apps that use the ACH network

• Moving money between your own accounts at different banks

How it works: When you initiate an ACH payment, your bank sends the transaction to the ACH network. The network sorts and sends it to the receiving bank, which then deposits the money into the recipient’s account. This network processes transactions in batches several times a day. Because payments are grouped together and cleared in cycles, they can take one to three business days to complete.

Families who use Greenlight’s debit card for kids often rely on ACH for direct deposit, like when a teen’s paycheck from a part-time job lands directly in their Greenlight account. This gives them instant access to their earnings in one place, making it easier to save, spend, or invest under parental guidance.

Pros of ACH

• Low or no fees

• Great for recurring or scheduled payments

• Secure, with consumer protections that may allow reversals in some cases

Cons of ACH

• Slower speed (1 to 3 business days)

• Payments can be delayed over weekends or holidays

What is a wire transfer?

A wire transfer is an electronic payment sent directly from one bank to another in real time (or close to it). Wire transfers are often used for:

• Large purchases, such as a home down payment

• Urgent payments that need to arrive the same day

• Sending funds internationally where speed and certainty are important

How it works: When you request a wire transfer, your bank verifies the funds and sends instructions directly to the receiving bank. Instead of going through a batch-processing network, the sending bank communicates directly with the receiving bank to move funds. Domestic wires often arrive within hours; international wires typically take one to two business days. Once received, the funds are immediately made available to the recipient.

Pros of wire transfers

• Speed: Often same-day for domestic transfers

• Reliable for large or time-sensitive payments

• Works for international transactions

Cons of wire transfers

• Higher fees (often $15 to $50 per transaction)

• Usually irreversible once sent

ACH vs. wire transfer: key differences

Choosing the right method for you

If you’re paying monthly bills, moving money between accounts, or setting up direct deposits, ACH is usually the most cost-effective and convenient choice. For situations where timing is critical, like a real estate closing or tuition payment, a wire transfer can be worth the extra cost.

No matter which method you choose, always double-check the recipient’s details before sending. Mistakes on a wire transfer can be costly since they’re difficult to reverse.
