In the United States, the use of cash has been steadily declining, but it remains a significant payment method, particularly for smaller transactions. Here's an overview based on recent data:
Cash Transactions: Recent data suggests that cash accounted for approximately 16% of all transactions in 2024, a decrease from 20% in 2021. This indicates a trend towards less cash usage over time.
In-Store Purchases: Cash is still widely used for in-store purchases, with 67% of Americans using it for physical transactions, demonstrating its enduring appeal for smaller, everyday purchases. However, this is often for transactions under $10, where nearly half (49%) are made with cash.
Demographic Trends: There's a notable income disparity in cash usage. Lower-income Americans use cash more frequently, with 22% of those from households earning less than $40,000 annually using cash for all or most of their purchases. In contrast, 73% of upper-income Americans use cash for only a few or none of their purchases.
Emergency and Specific Situations: Cash continues to be seen as an essential tool for emergencies, lending, and saving, with a significant portion of Americans valuing its privacy and immediacy in these contexts.
Overall, while there's a clear shift towards digital and card payments, cash retains a substantial role in the U.S. payment ecosystem, particularly in certain demographics and for specific types of transactions.
