Key Takeaways

  • 1Utilization = credit card balances ÷ credit limits.
  • 2Keep utilization under 30%; under 10% is ideal for top scores.
  • 3Pay down before statement closing date — that is what gets reported.
  • 4Request credit limit increases to lower utilization without paying debt.

Credit utilization is the second-largest factor in your FICO score. Lowering it is often faster than waiting for negative marks to age off.

See credit score ranges for context.

The 30% Rule

On a $10,000 total limit, keep reported balances under $3,000. Spread across cards — one maxed card hurts even if overall utilization is low.

Pay twice monthly if needed to keep reported balance low.

Before a Mortgage

Lower utilization 30–60 days before applying. Even a 20-point score bump can save thousands in interest.
