What actually affects your credit score

Five factors, ranked by weight, and what to do about each one.

  1. Payment history (~35%) — whether you pay on time. The single biggest factor.
  2. Amounts owed / utilization (~30%) — how much of your available credit you're using.
  3. Length of credit history (~15%) — the age of your accounts.
  4. Credit mix (~10%) — cards, loans, and other account types.
  5. New credit (~10%) — recent applications and hard inquiries.

The fastest lever: utilization

Utilization is your balance divided by your limit. Under 30% is the common guideline; under 10% is better. Paying a card down before the statement closes can move your score within one cycle.

Things that don't hurt your score

  • Checking your own credit report (that's a soft inquiry).
  • Your income, savings balance, or debit card use.
  • Carrying a balance — you do not need debt to build credit.
