What ACH payments cost: per-item pricing, returns and Same Day fees

ACH processing fees: the short answer

ACH costs are usually counted per payment, or per item, rather than as a percentage of the amount. That is the main difference from card costs, which grow with the size of the payment for the business receiving it.

For a sense of scale, the 2022 survey by the Association for Financial Professionals (AFP), as cited by the Federal Reserve Bank of Cleveland in September 2026, found median ACH fees of $0.25 to $0.50 per payment for each side: the organization sending the payment and the one receiving it.

Providers build ACH pricing in different ways, and network fees for unauthorized returns and Same Day ACH can come on top. Before you set prices for your customers, ask your provider exactly how its ACH pricing is built.

Network fees as of October 2026; the cost benchmark is the AFP 2022 median cited by the Cleveland Fed in 2026. The table shows network fees and a survey median, not any one provider’s prices.

Not a fee, so not in the table: Nacha’s return-rate threshold and levels, as of October 2026. Going over 0.5% unauthorized returns can bring enforcement; going over 3.0% administrative or 15.0% overall returns brings an inquiry.

Per-payment benchmarks for business payments

The AFP figures are median per-payment fees charged to the businesses on each side of a business payment. They are medians across many organizations, not any one provider’s price list, so use them as a yardstick when you read a quote rather than as a quote in themselves.

Against the ACH median of $0.25 to $0.50 per payment for each side, sending a paper check cost about $1, and a wire about $7 for each side.

The Cleveland Fed brief also shows how far ACH has spread in business payments: it made up 41% of B2B payments by number in 2024, up from 25% in 2015. If your customers bill other businesses, ACH is likely already familiar to their payers.

ACH vs card processing costs

The same AFP medians put the cost for a business receiving a card payment at 2.0% to 2.5% of the payment for a credit card and 1.0% to 1.5% for a debit card.

Card costs mostly track the payment amount because of how card pricing is built. Interchange is a fee set by the card network and paid between banks: the acquirer pays it to the card issuer. The business does not pay interchange itself; it pays a merchant discount to its own bank, which bundles interchange with other fees and is typically a percentage of each transaction.

So the gap between card and ACH costs grows with the payment. As a rough illustration using the medians, a $1,000 invoice paid by credit card would cost the receiver $20 to $25, against $0.25 to $0.50 by ACH. On a $20 payment, the credit card median works out to $0.40 to $0.50, close to the ACH range.

Cost is only part of the decision. Speed, returns, disputes and what your customers prefer matter too. Our guide to choosing between ACH and credit card payments weighs those trade-offs, and credit card processing fees explained breaks down interchange, network fees and markup on the card side.

ACH return fees

A returned debit is a payment your customer did not collect. Some returns also carry a network fee.

The Unauthorized Entry Fee is paid by the ODFI (the bank that sends the payment into the ACH Network) to the RDFI (the payer’s bank) for each debit returned as unauthorized, with return code R05, R07, R10, R11, R29 or R51. Nacha set it at $4.50 per return, starting with returns that settled on or after October 3, 2016. As of October 2026, Nacha’s rule page still shows $4.50, but confirm the current amount in the Nacha Operating Rules before you build it into your prices.

The ODFI usually passes the fee on to the Originator (the business collecting the payment) or the platform. Returns for other reasons do not carry the Unauthorized Entry Fee, but a provider may charge its own fee on any returned payment, so ask whether yours does and what it is.

To see what each code means and what to do when one arrives, read ACH return codes and what to do next.

Return rates cost more than fees

A single return fee is small. A high return rate is the bigger cost, because Nacha measures it and can act on it. As of October 2026, the rules set one threshold and two levels for debits:

• Unauthorized return rate threshold: 0.5% of debit entries, counting returns coded R05, R07, R10, R11, R29 and R51 over the preceding 60 days or two calendar months.
• Administrative return rate level: 3.0%, counting R02, R03 and R04 returns.
• Overall debit return rate level: 15.0%, counting all debit returns except RCK entries.

Going over the 0.5% threshold can trigger Nacha enforcement against the ODFI, which passes the obligation on to the Originator or Third-Party Sender. The 3.0% and 15.0% levels are not automatic violations. Going over one triggers a preliminary inquiry into the Originator’s or Third-Party Sender’s practices, which can lead to a directive to bring the rate down.

Every return you prevent is a payment your customer collects, one less possible fee and one step further from the levels that bring an inquiry.

The Same Day Entry Fee

Sending a payment as Same Day ACH adds a network fee. For each Same Day ACH entry, the ODFI pays the RDFI a Same Day Entry Fee. The Same Day ACH Phase 1 rule set it at 5.2 cents per entry, and Nacha announced in May 2026 that its eight-year review left it unchanged for another two years, so as of October 2026 it is still 5.2 cents. Return entries and notifications of change do not carry it.

A sponsor bank or processor may pass the fee through to your platform, either as the network fee alone or inside a separate same-day price.

Not every payment can go same day: International ACH Transactions (IAT) and Automated Enrollment Entries (ENR) are not eligible. For the processing windows and limits, see how Same Day ACH works. If only some of your customers’ payments need to move faster, sending just those same day keeps the fee on the payments that need it.

Keeping ACH costs down

Most of what you can control comes down to fewer returns.

• Validate the account on the first WEB debit. As of October 2026, Nacha’s rules require Originators of WEB debits (debits authorized online or through a mobile device) to validate the account the first time they use an account number and whenever it changes, as they have since March 19, 2021. The minimum is confirming that the account is open and can accept ACH entries; checking who owns it is not required. The method is up to the Originator, from prenotes and micro-entries to a validation service.
• Get clear authorizations. When payers know what they agreed to, for how much and when, they are less likely to report a debit as unauthorized, which is what brings the Unauthorized Entry Fee and counts toward the 0.5% threshold.
• Use a company name payers recognize. A debit that shows up on a bank statement under an unfamiliar name is easy to mistake for one that was never authorized.
• Watch your return rates. Track unauthorized, administrative and overall return rates against Nacha’s threshold and levels, so you can fix a problem before it draws an inquiry or enforcement.

Questions to ask a provider about ACH pricing

Whichever provider you talk to, put these questions to it. The answers tell you what ACH will cost your platform and your customers, not just the headline ACH transaction fees.

• How are ACH payments priced? Per payment, as a percentage of the amount or with another model.
• Which network fees are passed through? In particular the Same Day Entry Fee and the Unauthorized Entry Fee, and whether they are passed through at cost.
• What does a returned payment cost? Any fee of the provider’s own on top of a network fee, and whether it changes with the return reason.
• Is Same Day ACH offered, and at what cost? The network fee alone, or a separate same-day price.
• What happens if return rates rise? The steps the provider takes as your rates approach Nacha’s threshold and levels.
• How do fees appear on statements? Whether you can see each fee against the payment it belongs to, so you can price your own services with confidence.
