Key Information

  • Utilization = (Total Balance ÷ Total Limit) × 100
  • Under 30% is good, under 10% is excellent
  • Both overall AND per-card utilization matter
  • Utilization is calculated when statements close

Pro Tips

  • Pay before statement closing date, not just due date
  • Request credit limit increases (but don't spend more!)
  • Keep old cards open even if unused (helps utilization)
  • Spread spending across cards to keep per-card utilization low

Avoid These Mistakes

  • Maxing out one card while others are zero
  • Closing old cards (reduces total limit = higher utilization)
  • Only paying by due date (statement already reported high balance)
  • Not knowing when your statement closes
