What Actually Moves Your Credit Score (and What Doesn't)

Your credit score is not a judgment of your character. It's a prediction of whether you'll pay a lender back, built from five ingredients with very unequal weights.

The five factors, weighted

• Payment history, 35%. A single 30-day late payment can cost 50 to 100 points and stays on your report for seven years.
• Amounts owed, 30%. Mostly 'utilization': how much of your credit limits you are using.
• Length of credit history, 15%. The average age of your accounts. Don't close your oldest card.
• New credit, 10%. Each hard inquiry costs a few points for about a year.
• Credit mix, 10%. Having both revolving (cards) and installment (loans) accounts helps a little.

Two fixes that work in weeks, not years

First, get utilization under 30%, ideally under 10%, on every card, not just in total. Paying the balance down a few days before the statement closes changes the number the bureaus see. Second, ask for a credit-limit increase on your oldest card. A higher limit with the same spending lowers utilization instantly.

The slow lever is time. Put the minimum payment on autopay for everything so a forgotten bill never becomes a 35% problem, then let the account ages do their work.
