How Credit Scores Actually Work (In Plain English)

A credit score is a three-digit summary of how you have handled borrowed money. Lenders use it to estimate how likely you are to repay on time. It is not a measure of income, savings, or personal worth.

Payment history is the heaviest factor. One 90-day late payment can drop a strong score meaningfully and stays on your report for up to seven years. Automating minimum payments is the simplest protection available.

Credit utilization — the balance you carry compared to your limits — is second. Keeping reported balances under roughly 30 percent, and ideally under 10 percent, gives you the best result. Utilization has no memory, so it can improve within a single billing cycle.

Length of credit history, credit mix, and new credit inquiries fill out the rest. These move slowly, which is why patience matters more than tricks.
