What Actually Moves Your Credit Score

Your credit score is a three-digit summary of how reliably you repay borrowed money. It quietly shapes the interest rate on your mortgage, car loan, and credit cards — and sometimes your apartment application or insurance premium. Knowing what moves it puts you in control.

The five factors

Most scores (like FICO) weigh roughly five inputs:

• Payment history (~35%). Do you pay on time? This is the single biggest factor. One payment 30+ days late can dent your score for years.
• Amounts owed / utilization (~30%). How much of your available credit are you using? Keeping balances below 30% of your limits — and ideally under 10% — helps.
• Length of credit history (~15%). Older accounts help. This is why closing your oldest card can backfire.
• Credit mix (~10%). A blend of card and installment loans looks slightly better than one type alone.
• New credit (~10%). Many applications in a short window can ding your score temporarily.

The two that dominate

Payment history and utilization together are about two-thirds of the score. Master those two and the rest is fine-tuning:

1. Never miss a due date. Automate at least the minimum payment on everything.
2. Keep balances low relative to limits — pay down before the statement closes, or ask for a higher limit (and then do not use it).

What does not hurt your score

• Checking your own credit (a "soft" inquiry).
• Earning more or less money — income is not in the score.

Quick wins

• Set autopay to avoid late marks.
• Pay down cards to lower utilization — this can move a score within a month or two.
• Keep old accounts open to preserve history.

The takeaway

You do not need tricks. Pay on time, every time, and keep your balances low. Those two habits build the score; time does the rest.
