Saved per payment$64.90

Saved per month$7,788

The cap is what makes ACH compelling for large payments, a $2,400 invoice costs $5.00 instead of $69.90. Against that, settlement takes days rather than being near-instant, and payments can be returned for insufficient funds up to two days later, or far longer for a disputed consumer debit. A flat $0.50 per transfer is a common alternative structure.

How the ACH Fee Calculator works

ACH is priced with a cap, which is the whole point. A card fee scales forever with the invoice; an ACH fee stops at a few dollars. On large B2B invoices the difference is not marginal; it is the difference between a rounding error and a real cost.

How the number is derived

ACH and equivalent bank transfer rails charge a flat fee per transaction, or a low percentage with a cap, rather than a percentage of the full amount. Cost = flat fee, or amount × rate capped at a maximum.

That structure inverts the card economics entirely: cost per transaction is roughly constant regardless of size, so the effective rate falls to nearly nothing on large payments.

An example

A $58 payment at a $0.25 flat ACH fee: an effective 0.43%, against $1.98 and 3.41% on a card. The card costs eight times more.

On a $2,000 invoice the gap is decisive: $0.25 by ACH against $58.30 by card. On a business invoicing $200,000 a month, moving from cards to ACH saves roughly $5,800 a month.

Even a percentage-based ACH product with a 0.8% rate capped at $5 costs $5 on that $2,000 invoice, against $58.30 by card.

The usual mistakes

ACH is slower. Standard settlement takes one to three business days and same-day options cost more, so the saving is partly paid for in cash timing.

Returns are also different from chargebacks and can arrive later. An unauthorised debit can be returned well after settlement, and for consumer transactions the return window is considerably longer than most merchants expect.

What this changes

Offer ACH on anything above a few hundred dollars, and make it the default on B2B invoices. The saving is large, the customer is indifferent, and it is the single largest payment cost reduction available to most invoicing businesses.

Then price the difference explicitly where it helps. A small discount for paying by bank transfer costs less than the card fee it avoids and shifts a meaningful share of volume.

Where bank rails win and where they do not

They win on large, recurring, business-to-business payments where the payer is known, the amount is predictable and a day or two of settlement makes no difference. Subscription billing, wholesale invoicing and retainer payments are the clearest cases.

They lose on consumer checkout, where the friction of entering bank details and the delay in confirmation both hurt conversion badly. A consumer buying a $58 item will not authenticate a bank transfer to save the merchant $1.73.

Open banking payment initiation is narrowing that gap in markets where it is established, offering bank-rail costs with a card-like checkout experience. Where it is available it is worth testing on higher-value consumer orders, which is where the fee saving is large enough to justify any conversion risk.

Consumer ACH debits carry a much longer return window than business ones, and an unauthorised return can arrive months after settlement.

For a business shipping goods against an ACH payment, that means the funds appearing in the account is not the same as the payment being final. Waiting for the return window on high-value first orders from unknown customers is a reasonable precaution and one that card economics never require.

One last operational note: account validation before the first debit removes most failed payments, which each carry their own return fee. Verifying once at setup is cheaper than a returned payment on every failed attempt.

Where to go next

The ACH Fee question rarely arrives on its own. These are the ones that usually come with it:

Credit Card Processing Fee Calculator — Effective rate, not the headline rate.
Cash Discount vs Surcharge Calculator — Same money, different advertised price.
Payment Gateway Fee Comparison Calculator — Where a monthly fee starts paying for itself.
Etsy Fee Calculator — Every Etsy fee on one sale, itemised.

Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price, check the platform's current fee schedule before you price a product against it. This is not tax or business advice.

Frequently asked questions

What does ACH cost?

Commonly around 0.8% capped at $5, or a flat fee of 25 cents to $1.50 per transfer depending on the provider. Either way it stops scaling, unlike a card fee.

When is ACH clearly better?

Large recurring payments: B2B invoices, subscriptions above a few hundred, rent, wholesale orders. Below about $100 the cap never binds and cards are competitive on convenience.

What are the drawbacks?

Settlement takes days rather than being near-instant, and payments can be returned for insufficient funds up to two business days later. Unauthorised consumer debits can be disputed for far longer.

How do I get customers to use it?

Offer a discount that costs you less than the card fee you avoid, and make it the default on large invoices. B2B customers frequently prefer it anyway once it is offered.
