ACH vs Wire Transfer: Cost, Speed & When to Use Each
Two ways to move money between bank accounts: one free and slow, one fast and pricey. Here's how they differ and which to use when.
The short answer
Use ACH for almost everything: it's free (or a few dollars), and the one-to-three-day wait rarely matters for payroll, bills or moving money between your own accounts. Reach for a wire only when you need same-day, guaranteed settlement (a house deposit, a time-sensitive business payment) or when you're sending internationally and the recipient's bank requires it. The wire's speed costs a fee, $25 to $30 (nothing at Fidelity) for a domestic one at US banks (their published fees, checked June to October 2026), and it can't be undone once sent.
ACH vs wire, compared
A wire is final, and that is the risk. Because wires can't be reversed, they're the scammer's favorite. ACH payments can usually be disputed and clawed back. Only wire to people and businesses you trust.
When to use each
- Payroll, bills, subscriptions, moving your own money:
- ACH. It is free and reliable, and the timing is predictable.
- Closing on a house, a same-day business payment, a deposit with a deadline:
- a wire, when the money has to land today with certainty.
- Sending abroad:
- a wire works, but compare it against a specialist first, because the bank's exchange-rate markup usually costs more than the fee.
- Paying someone you don’t fully trust:
- avoid a wire, since its irreversibility offers you no protection.
Paying for a wire? Make sure it's worth it. The wire transfer fee calculator shows the true all-in cost, and the bank wire fee comparison covers Chase, Bank of America and Wells Fargo.
The cheaper international option
ACH can't cross borders, and an international bank wire adds up: US banks charge $30 to $75 (nothing at Fidelity) to send one (their published fees, checked June to October 2026), a correspondent bank typically takes about $20 on the way, and the bank converts at a markup it doesn't publish; where we could measure it (Chase and Wells Fargo, on October 7, 2026, as Wise’s public comparison of bank rates showed it), it ran 2.9% to 4%. For cross-border transfers, price a specialist like Wise or OFX against it: Wise converts at the real mid-market rate for a stated fee, and OFX takes its margin in the rate.

Frequently Asked Questions
What is the difference between ACH and a wire transfer?
ACH moves money in batches through the US automated clearing house network. It is free or a few dollars at most but takes one to three business days. A wire moves funds individually and settles the same day domestically, but US banks charge $25 to $30 (nothing at Fidelity) to send one (their published fees, checked June to October 2026). ACH is reversible if something goes wrong; a wire is effectively final once sent.
Is ACH or a wire cheaper?
ACH, by a wide margin: it is free or a few dollars at most, while US banks charge $25 to $30 (nothing at Fidelity) for a domestic wire and $30 to $75 (nothing at Fidelity) for an international one in US dollars (their published fees, checked June to October 2026), and an international wire adds an exchange-rate markup on top. The wire’s only advantage is speed and certainty, so pay for it only when you actually need same-day, guaranteed settlement.
Can I send an international payment by ACH?
Standard ACH is a US-only network, so it cannot send money abroad directly. International ACH-style payments exist but are slow and limited. For cross-border transfers a bank wire works, but compare it with a specialist first: Wise gives the real exchange rate for a stated fee, and a broker like OFX takes its margin in the exchange rate instead.
Is a wire transfer safe?
A wire is secure and final, which is exactly why scammers favor it: once sent, it is almost impossible to reverse. ACH offers more protection, since unauthorized or mistaken payments can often be disputed and clawed back. Only wire money to people and businesses you trust, and double-check the details first.
How long does each one take?
An ACH transfer clears in one to three business days. A domestic wire usually arrives the same business day if sent before the cutoff; an international wire takes one to five business days as it passes through correspondent banks. If timing is not critical, ACH saves you the fee.
