What actually moves your credit score, and what doesn’t
Payment history and credit utilization make up nearly two-thirds of a FICO score. Here’s how the credit score factors work, and what doesn’t count.
In this article
Credit scores can feel arbitrary, but the main ingredients are public. FICO, the company behind the scores most lenders use, publishes how much each of the credit score factors matters for the general population.
The five credit score factors
| Category | Share of a FICO score |
|---|---|
| Payment history | 35% |
| Amounts owed | 30% |
| Length of credit history | 15% |
| New credit | 10% |
| Credit mix | 10% |
These weights are averages. For someone with a short credit history, for example, the balance among categories can look different. But the order is a useful guide: the first two categories make up nearly two-thirds of the score.
The biggest lever: paying on time
Payment history is the single largest factor. A payment usually isn’t reported to the credit bureaus as late until it’s at least 30 days past due, and a late payment can stay on your report for up to seven years. Its effect fades over time, especially if you keep a clean record afterward.
The simplest protection is to set up automatic payments for at least the minimum on every account, then pay more by hand when you can.
Utilization: how much of your limit you use
“Amounts owed” is largely about credit utilization, the share of your available credit card limits you’re using. If you have $10,000 in total limits and $3,000 in balances, your utilization is 30%.
Lower is generally better. Keeping utilization under 30% is a common rule of thumb, and people with the highest scores often stay well below 10%.
One detail trips people up: card issuers typically report the balance on your statement, not the balance after you pay. If you pay in full every month but your statement shows a large balance, your utilization can still look high. Making a payment a few days before the statement closing date lowers the reported balance.
Things that don’t hurt the way people think
- Checking your own score or report. That’s a soft inquiry. It doesn’t affect your score, no matter how often you do it.
- Your income. It isn’t part of your credit report, so it isn’t part of your score, though lenders consider it separately.
- Paying your card in full. You don’t need to carry a balance or pay interest to build credit. That’s a myth. Paying in full also keeps your grace period, so purchases stay interest-free.
Things that can backfire
- Closing an old card. Your total available credit drops, which can raise your utilization. Over time it can also shorten your credit history.
- Several applications at once. Each formal application usually triggers a hard inquiry, which can cost a few points. Hard inquiries stay on your report for two years, though FICO only counts them in your score for 12 months. For mortgages, auto loans and student loans, inquiries made within a short shopping window are generally counted as one.
- Co-signing. If the other person pays late, it shows up on your report too.
How long changes take
In the scoring models most widely used today, utilization reflects your current balances, so paying down a card can lift your score as soon as the lower balance is reported, often within a month or two. Rebuilding after late payments takes longer, usually many months of on-time payments.
If something on your report looks wrong, you can dispute it. Here’s how to dispute a credit report error, step by step.
Do not optimize for a single point
Scores naturally move as issuers report balances and accounts age. A five-point change does not necessarily mean you did something wrong, and different lenders may use different FICO versions or another scoring model altogether.
Focus on the durable habits visible in every model: pay on time, keep card balances manageable, apply for new credit only when it serves a purpose and check the underlying reports for errors. Those actions matter more than timing a payment to make a score look perfect on an ordinary Tuesday.
