Living paycheck-to-paycheck describes a financial situation where a person's income is entirely consumed by expenses before the next paycheck arrives, leaving little or no financial buffer. In this cycle, even a small unexpected expense — a car repair, a medical bill, or a missed shift — can cause serious financial disruption. It is a widespread reality in the U.S., affecting people across a broad range of income levels, not just those in lower income brackets. Breaking the cycle typically requires a combination of expense reduction, income growth, and building even a small emergency fund to create a financial cushion.
