Does Carrying a Balance Help Your Credit Score

A common piece of credit advice says you should carry a small balance on your credit card because it helps your score. This is not true. It is one of the most stubborn myths in personal finance and it costs people money in unnecessary interest every month.

Where This Myth Comes From

The confusion seems to come from true-but-misunderstood utilization advice. It is accurate that 0% utilization is slightly suboptimal for your score - the model wants to see some activity. People extrapolated from that to mean you should carry a balance. The reality is different.

What you need is for a non-zero balance to be reported to the bureaus. That happens when your statement closes with a balance on it. You can then pay that balance in full before the due date. The bureau saw a balance, your score gets the benefit of showing utilization, and you paid zero interest.

What the Scoring Model Actually Measures

The FICO model evaluates your credit utilization ratio based on the balance reported on your statement - not your end-of-month balance, not whether you paid in full. It also measures payment history, which is whether you paid on time. Neither of these rewards carrying a balance.

The Real Cost of Following This Myth

If you carry a $500 balance on a card with 24% APR, that is about $120 per year in interest charges. At $1,000, it is $240 per year. Over time, people following this advice have paid hundreds to thousands of dollars in completely unnecessary interest for zero credit score benefit.

There Is No Benefit to Carrying a Balance

Pay your statement balance in full every month. Your score does not know whether you paid in full or carried part of it forward - it only sees the balance that was reported when the statement closed and whether you paid your minimum on time. Full payment, no interest, same or better score. The myth costs you money and nothing else.
