Quick answer

Utilization counts for about 30% of a FICO score. Keeping it below 30% is good and below 10% is excellent. Paying before the statement date lowers the balance reported to the bureaus.

How it works

Enter the balance and limit of up to five cards and your target utilization.

Tips

  • Compare loans by APR and total cost, not just the monthly payment.
  • Extra payments go straight to principal and can save a lot of interest.
  • Pay off the highest-rate debt first if you want to save the most money.
  • Check for prepayment penalties before paying a loan off early.

Common mistakes to avoid

  • Stretching a loan term to lower the payment without seeing the extra interest.
  • Paying only the minimum on credit cards.
  • Forgetting fees that are rolled into the loan.

What each result means

  • Total balances = [Card 1 balance] + [Card 2 balance] + [Card 3 balance] + [Card 4 balance] + [Card 5 balance]
  • Total credit limits = [Card 1 limit] + [Card 2 limit] + [Card 3 limit] + [Card 4 limit] + [Card 5 limit]
  • Overall utilization = [Total balances]÷[Total credit limits]×100
  • Pay down to reach the target = max([Total balances] – [Total credit limits]×[Target utilization]÷100, 0)

Example values

How the main result changes when Card 1 balance changes and everything else stays at the example values above:

Card 1 balance Overall utilization (%)
600 17.5
900 21.25
1,200 25
1,500 28.75
1,800 32.5
2,400 40

Formula

Utilization = balance ÷ credit limit × 100 (per card and overall)Balance to reach a target = target % × total limit

Worked example

Inputs — Card 1 balance: $1,200; Card 1 limit: $5,000; Card 2 balance: $800; Card 2 limit: $3,000; Card 3 balance: $0; Card 3 limit: $0; Card 4 balance: $0; Card 4 limit: $0; Card 5 balance: $0; Card 5 limit: $0; Target utilization: 10 %.
Results — Total balances = $2,000.00; Total credit limits = $8,000.00; Overall utilization = 25 %; Card 1 utilization = 24 %; Card 2 utilization = 26.67 %; Card 3 utilization = 0 %; Pay down to reach the target = $1,200.00; Rating = Good (under 30%).

Frequently asked questions

What is a good credit utilization ratio?

Under 30%, ideally under 10%.

Does closing a card hurt utilization?

It can, because your total limit falls.

Is utilization per card or overall?

Both are considered by scoring models.

What formula does the Credit Utilization Calculator use?
