What Actually Moves Your Credit Score

Most credit scoring models (FICO is the most widely used) weigh five factors. Knowing the rough weight of each tells you where to actually spend your effort.

Payment history — the biggest factor

Whether you've paid on time is the single largest input. One 30-day-late payment can drop a good score meaningfully, and the effect lingers for years, though it fades over time. If you're only going to fix one habit, this is it: never miss a due date, even for a payment you're disputing — dispute after paying, not instead of paying.

Credit utilization — the second biggest

This is the percentage of your available credit you're currently using, and it's recalculated every billing cycle from whatever balance gets reported — not just "maxing out" a card. Keeping reported utilization under 30% helps; under 10% is where you see the best results. Paying your statement balance in full doesn't help utilization if a high balance was still reported before the payment posted, which is why people are sometimes surprised their score dipped despite paying on time.

Length of credit history

Older accounts help, which is the real reason to think twice before closing your oldest credit card even if you don't use it — closing it can shorten your average account age. There's not much you can do to speed this factor up other than not closing old accounts unnecessarily.

Credit mix

Having a mix of account types (credit cards, an auto loan, a mortgage) helps slightly, but this is a minor factor — it's not worth taking out a loan you don't need just to diversify your mix.

New credit

Opening several new accounts in a short window signals risk and causes a small, temporary dip from the hard inquiry itself. One new account for something you actually need isn't a problem; five applications in a month for cards you don't need is.

In order of what to actually prioritize: never miss a payment, keep utilization low, and leave old accounts open. Everything else is secondary.

What doesn't help

Checking your own score (a "soft" pull) doesn't affect it. Paying off a collections account doesn't erase it from your report, though some models weigh paid collections less than unpaid ones. There's no legitimate shortcut that beats time plus the two big factors above.
