Payment history, amounts owed, length of history, new credit, and credit mix — here's the weight each one carries and where to focus first.
Your credit score isn't one number so much as a summary of how you've handled borrowed money over time. Lenders use it to estimate how likely you are to repay, and the algorithms that produce it weigh a handful of behaviors differently. Knowing which ones matter most lets you spend your energy where it actually moves the needle.
Payment history sits at the top for a reason: a lender's biggest question is whether you'll pay them back at all. A single missed payment can ding a strong score more than you'd expect, and the more recent it is, the more it stings. After that, amounts owed — really, how close your balances sit to your limits — is the next biggest lever, and it's one you can pull quickly by paying balances down.
The remaining three factors matter, but they're slower to influence. Length of history rewards accounts you've kept open for years, so closing old cards can quietly cost you. New credit and credit mix each carry a smaller weight, and while opening several accounts in a short window can look risky, a healthy mix of installment and revolving credit tends to help over the long run.
Spend your energy on the two factors that account for roughly two-thirds of your score — paying on time and keeping balances low.
Key takeaways
- Payment history is the single biggest factor — pay on time, every time.
- Keep balances well below your limits; under 30% utilization is a common benchmark.
- Don't close your oldest cards without a reason — length of history matters.
- Open new accounts only when you need them; bunching applications can cost points.
