What this calculates

Credit utilization calculator for credit cards. Enter balances and limits to see your utilization ratio and how much to pay down to reach 30% or 10%.

How to use it

  1. Use statement balances the bureaus are likely to see, not today's app balance if it has not reported.
  2. If you are applying for a mortgage, 10% is a cleaner target than 30%.
  3. Paying before the statement date often helps more than paying after.

Common mistakes

  • Closing old cards and shrinking limits.
  • Maxing a store card while overall utilization looks fine.
  • Carrying a balance to 'build credit' at 20%+ APR.

Formula

Utilization = balances ÷ limits. Paydown to 30% = max(0, balances − 0.3 × limits).

How credit utilization works

What credit utilization is

Credit utilization is the share of your revolving credit limits that you are using. Add up the balances on your credit cards and other revolving lines, then divide by the total of their limits. If you owe $8,200 on cards with $24,000 of total limits, your utilization is about 34%.

Why it matters

Amounts owed are a large part of common credit scores, and revolving utilization is one of the main parts of that. Lower is usually better. Many lenders and scoring guides point to staying under 30%, and people with top scores often stay under 10%. Utilization has no long memory in most scoring models, so paying down a balance can help as soon as the lower balance is reported.

How this calculator works

Enter your statement balances and your total revolving limits. The tool shows your utilization ratio, the credit you still have open, and the paydown needed to reach 30% and 10%. With the defaults, you would pay about $1,000 to reach 30% and about $5,800 to reach 10%.

Overall and per card

Scores look at both overall utilization and each card on its own. One card near its limit can hurt even if the total is low. Run the calculator once for all cards, then once for your highest card.

Ways to lower it

Pay before the statement date, since that balance is usually what gets reported. Spread spending across cards. Ask for a higher limit on a card you manage well. Avoid closing old cards, which removes their limits. If you are preparing for a mortgage or a rental loan, start a few months early so the lower balances show on your report.

Credit as part of a bigger plan

Strong credit lowers the cost of buying a home or rental property. It works best when it is part of a plan for cash flow, debt, taxes, and investing.

FAQ

Is 0% utilization best?

Very low is good. Some people keep a small reported balance so the file shows activity. Do not pay interest for that.

Do mortgages count?

Not in this revolving ratio. They hit DTI instead.

Will this raise my score by X points?

No model here can promise points. It shows the ratio lenders still quote.

How do I calculate credit utilization?

Divide your total revolving balances by your total revolving limits and multiply by 100. For example, $3,000 of balances on $10,000 of limits is 30%.

What is a good credit utilization ratio?

Under 30% is a common guideline. Under 10% is typical for people with top scores. Check each card as well as the total.

Is credit card utilization counted per card or in total?

Both. Scoring models look at your overall ratio across all cards and at the ratio on each card. Run the calculator once with every card, then once for each card on its own.
