What does a credit score indicate?

A credit score is a numerical representation of a person's creditworthiness, which is primarily a prediction of how likely an individual is to repay borrowed money. It is calculated based on various factors including payment history, amounts owed, length of credit history, new credit, and types of credit used. Essentially, a credit score assesses the risk that lenders take when they lend money or extend credit to an individual. A higher credit score suggests that a person is more likely to fulfill their repayment obligations reliably, while a lower score may indicate a higher risk to lenders.

The other options do not accurately reflect the purpose of a credit score. Although it's influenced by spending habits over time, the score itself is not a direct measure of those habits (as indicated by the second option). Total wealth and income level are also not factors directly associated with credit scores; instead, they focus on borrowing behavior and financial responsibility as predicted through credit activities.
