What might be a consequence of overspending on credit cards?

Overspending on credit cards primarily leads to the accumulation of debt, which is why this answer is correct. When individuals use credit cards beyond their means, they are essentially borrowing more money than they can comfortably repay. This can result in high balances that accrue interest, leading to a financial situation where they owe more than they can pay off in a timely manner. Over time, this debt can become unmanageable, potentially affecting credit scores and overall financial health.

In contrast, options such as increased savings or reduced credit card usage in the future do not directly result from overspending. Instead, individuals might find their financial situation worsens due to the debt incurred. Higher credit limits can result from good credit management, but overspending tends to lead to lower credit scores instead, which can limit future borrowing capabilities. Thus, the correct answer highlights the direct consequence of overspending: an increase in financial debt.
