Here’s the direct answer: ACH is by far the cheapest way to get paid, typically $0.20 to $1.50 per transaction, while wire transfers cost roughly $25 to $50 and credit cards run about 2.6% to 3.5% of the sale. The difference is dramatic at scale. A $5,000 invoice paid by card could cost you $100 or more in fees; the same invoice paid by ACH might cost less than a dollar. If you invoice other businesses for meaningful amounts, steering payments to ACH is one of the fastest ways to protect your margin.
That said, cheapest isn’t always best. Each method trades cost against speed, convenience, and protection, and picking purely on price can cost you sales or leave you exposed. The right move is matching the method to the situation.
Key Takeaways
- ACH is cheapest: roughly $0.20–$1.50 flat, or 0.5%–1.5% with percentage pricing.
- Wires are expensive but fast: $25–$35 domestic, $35–$50 international.
- Cards cost the most on large sales at about 2.6%–3.5% plus a per-transaction fee.
- The gap explodes with size: a $5,000 invoice costs $100+ by card versus under $1 by ACH.
- Match method to purpose, since speed and buyer convenience matter too.
What Each Method Actually Costs
The three methods aren’t remotely close on price. According to industry data on ACH fees, most ACH transactions cost between $0.20 and $1.50, or 0.5% to 1.5% under percentage pricing. Wire transfers, by contrast, carry flat fees of roughly $25 to $35 for a domestic outgoing wire and $35 to $50 internationally, plus an FX markup of 1% to 3% on international transfers that often dwarfs the stated fee. Cards, per Nav, run roughly 2.6% to 3.5% plus 10 to 30 cents.
| ACH | Wire transfer | Credit card | |
|---|---|---|---|
| Typical cost | $0.20–$1.50 | $25–$50 | 2.6%–3.5% + fee |
| Cost on $5,000 | Under $1 | ~$30 | $130–$175 |
| Speed | 1–2 business days | Same day | Instant authorization |
| Reversible? | Somewhat | Very difficult | Yes (chargebacks) |
| Best for | Recurring & B2B invoices | Large, urgent, international | Small sales, consumers |

A Realistic Example of the Savings
Consider an illustrative case. Elena’s consulting firm bills roughly $60,000 a month across a dozen B2B clients, and out of habit she let everyone pay by credit card. At an effective rate near 2.9%, she was handing over about $1,740 a month, more than $20,000 a year, purely in processing fees. She switched her recurring B2B clients to ACH, keeping cards available only for small one-off charges. ACH cost her roughly $1 per payment, so her monthly fees dropped from about $1,740 to under $20. Clients barely noticed, since a bank debit is standard in B2B, and Elena effectively gave herself a $20,000 raise without raising a single price or signing a single new client.
When Cards Are Worth the Cost
Don’t read this as “never take cards.” For consumer-facing sales, small transactions, and e-commerce, cards are essential: customers expect them, they’re instant, and refusing them costs you far more in lost sales than you’d save in fees. Cards also offer buyer protection that some customers specifically want. The cost only becomes painful on large invoices, which is exactly where ACH shines. The smart approach is to offer cards where convenience drives revenue and steer large B2B invoices toward ACH.
When a Wire Is Worth It
Wires are expensive, but they buy two things ACH can’t: speed and finality. For a same-day, high-value transaction (a real estate closing, a large equipment purchase, an urgent international supplier payment), a $30 fee is trivial relative to the amount moving and the certainty you get. Wires are also very hard to reverse, which protects the recipient and is precisely why wire fraud is so dangerous for the sender. If you’re paying by wire, always verify account details by phone using a known number, never from an emailed invoice.
How to Steer Clients Toward ACH
Most B2B clients will happily pay by ACH if you make it the obvious path. List ACH first on your invoice and make card payment a secondary option. Some businesses add a small surcharge for card payments or offer a modest discount for ACH, though surcharging is regulated, so confirm the rules in your area first. For recurring clients, simply set them up on ACH from the start rather than defaulting to cards. Since customers usually don’t care much either way, the default you choose largely determines what you pay.
Frequently Asked Questions
Is ACH cheaper than a credit card?
Dramatically, especially on large amounts. ACH typically costs $0.20 to $1.50 per transaction regardless of size, while cards charge a percentage. On a $5,000 invoice, that’s under $1 versus well over $100.
How long does an ACH transfer take?
Standard ACH transfers usually settle in one to two business days. Same-day ACH is available for an additional fee if you need the money faster, though it’s still typically cheaper than a wire.
Why are wire transfers so expensive?
Wires are processed individually and settle almost immediately through the banking system, rather than being batched like ACH. You’re paying for speed and finality, which is why they’re used for large, urgent, or international payments.
Can ACH payments be reversed?
ACH transfers can be reversed in limited circumstances, such as an error or unauthorized debit, typically within a defined window. They’re less reversible than card payments, which customers can dispute via chargeback, but more reversible than wires, which are nearly final.
The Bottom Line
ACH is the cheapest payment method by a wide margin, wires buy speed and finality at a flat premium, and cards cost the most on large sales but drive convenience and consumer sales. Use cards where they win you business, wires where speed and certainty justify the fee, and ACH for recurring and large B2B invoices. For a business invoicing meaningful amounts, simply making ACH the default can save thousands a year, without raising prices or losing a single client.
