Debit cards remain one of the most important payment methods in the U.S.
According to Payments Dive’s report on the Federal Reserve’s latest triennial payments study, debit cards once again accounted for the largest share of noncash payments. The Fed’s 2025 study, released in July 2026, uses payment data from calendar year 2024. That is the most recent broad national payment-volume data available from the Fed.
Reporting data like this is always somewhat dated, but that does not make it irrelevant. It gives merchants a reliable baseline for understanding where consumer payment behavior has been moving and what that may mean for payment strategy today.
The numbers show that debit is still dominant. Debit card transactions reached 120.6 billion in 2024, keeping debit at the top of the payment stack.
For merchants, the message is clear: debit is still essential.
But the report also shows that customer payment behavior is shifting. Debit cards still had the highest total transaction count in 2024, but credit cards added more new transactions from 2021 to 2024. Credit card payments rose by 16.2 billion transactions, reaching 67.1 billion in 2024. Debit card payments rose by 13.8 billion transactions, reaching 120.6 billion.
ACH payments also continue to carry the highest total dollar value. In 2024, ACH payments reached $104 trillion, accounting for nearly three-quarters of noncash payment value.
That means merchants should not just ask, “Do we accept debit?”
They should ask whether their payment strategy reflects how customers are actually paying today.
Why This Matters in 2026 and Beyond
Debit remains important because many customers use it for everyday purchases, budgeting, and avoiding credit card debt. For debit card users, it is often the payment method tied most directly to daily financial control.
For merchants in 2026, that makes debit acceptance a customer-experience issue as much as a payment-processing issue.
If debit transactions are expensive, unreliable, poorly routed, or difficult to use in mobile checkout, merchants may lose sales from customers who are ready to buy but do not want to use credit.
At the same time, merchants should not assume debit is the whole story. Credit cards are growing, ACH carries major dollar volume, mobile wallets continue to expand, and customers expect more flexibility at checkout.
Review Debit Costs and Routing
Debit is often assumed to be cheaper than credit, but merchants should still review the details.
Important items to check include:
- Debit transaction volume
- PIN debit versus signature debit mix
- Network routing options
- Card-present versus card-not-present costs
- Monthly processor fees
- Assessment and network fees
- Chargeback and return fees
- Average ticket size by payment type
- Effective processing rate
Merchants should ask their processor whether debit transactions are being routed in the most cost-effective way available. Routing can affect cost, especially for businesses with high debit volume.
Do Not Ignore Credit, ACH, and Wallet Growth
Even though debit leads by transaction count, customer behavior is becoming more varied.
Credit cards remain important for rewards, larger purchases, travel, business expenses, and customers who want more flexibility. ACH is especially important for bills, recurring payments, high-dollar transactions, and business-to-business payments.
Cash use is also declining, but it has not disappeared. Fed research cited by Payments Dive showed that the share of consumers who used cash fell from 87% in October 2023 to 83% in October 2024.
Merchants should match payment options to the type of transaction.
A quick-service restaurant may rely heavily on debit and mobile wallets. A contractor may benefit from ACH. An online retailer may need debit, credit, wallets, and buy now pay later options. A subscription business may need account-based payments and strong retry tools.
The Main Takeaway
Debit cards are still central to U.S. payments, but merchants should not treat payment acceptance as a set-it-and-forget-it function.
The payment mix is changing. Debit still leads, credit is growing quickly, ACH carries major dollar volume, and customers expect more flexibility at checkout.
For merchants today and beyond, the practical recourse is to review debit costs, optimize routing, support multiple payment methods, and monitor how customers actually pay.
Debit still matters. But the future belongs to merchants that build a flexible, cost-aware, customer-friendly payment mix.
