Your personalized analysis

Summary

Your overall utilization is 28.7% — good

You are carrying $6,600 against $23,000 of total credit. Utilization is about 30% of a FICO score, second only to payment history, and unlike late payments it has no memory — it recalculates every time your issuers report. That makes it the fastest lever you have, often visible within a single billing cycle.

Opportunity$4,300 to reach the top band

Paying $4,300 more would put you under 10%

You are already below the 30% threshold, which handles most of the damage. Getting under 10% captures the remaining benefit — consumers with scores above 800 typically report utilization in the 1–9% range. Note that reporting 0% on every card is very slightly worse than reporting a small balance, since scoring models want to see the accounts being used.

Watch out$2,300 on Card 2

Card 2 is at 76% on its own

Utilization is evaluated per card as well as overall, so a single maxed card hurts even when your total ratio looks acceptable. Paying $2,300 on Card 2 alone would bring it under 30%. Prioritize the highest-utilization card over the highest balance for score purposes.

Summary6.5% improvement

Paying $1,500 takes you to 22.2%

That moves you from the good band to good. Timing matters as much as amount: issuers report your statement balance, not your post-due-date balance, so paying before the statement closes gets the lower number onto your report a full month earlier.

Opportunity

A limit increase improves the ratio without paying anything

Requesting a credit limit increase raises the denominator. Increasing your total limit from $23,000 to $29,900 would drop utilization from 28.7% to 22.1% with no payment at all. Many issuers grant increases with a soft inquiry — ask before applying, and only do this if you are confident the extra room will not get used.

Next step

Pair this with a payoff plan

Utilization improves your score, but the balances still cost you interest every month. Run the debt payoff calculator to get an actual payoff date and see what the interest is costing you in the meantime.

Summary

Your overall utilization is 84% — very poor

You are carrying $4,200 against $5,000 of total credit. Utilization is about 30% of a FICO score, second only to payment history, and unlike late payments it has no memory — it recalculates every time your issuers report. That makes it the fastest lever you have, often visible within a single billing cycle.

Recommendation$2,700 to clear the 30% threshold

Pay $2,700 to cross below 30%

The 30% threshold is where scoring models stop treating utilization as a meaningful negative. Paying $2,700 across your cards would take you from 84% to just under 30%. If you can reach $3,700, you would land under 10%, which is where scores above 800 typically sit.

Watch out$2,700 on Card 1

Card 1 is at 84% on its own

Utilization is evaluated per card as well as overall, so a single maxed card hurts even when your total ratio looks acceptable. Paying $2,700 on Card 1 alone would bring it under 30%. Prioritize the highest-utilization card over the highest balance for score purposes.

Summary

Your overall utilization is 1.6% — excellent

You are carrying $570 against $35,000 of total credit. Utilization is about 30% of a FICO score, second only to payment history, and unlike late payments it has no memory — it recalculates every time your issuers report. That makes it the fastest lever you have, often visible within a single billing cycle.

Opportunity

A limit increase improves the ratio without paying anything

Requesting a credit limit increase raises the denominator. Increasing your total limit from $35,000 to $45,500 would drop utilization from 1.6% to 1.3% with no payment at all. Many issuers grant increases with a soft inquiry — ask before applying, and only do this if you are confident the extra room will not get used.

The basics

What credit utilization is and why it moves so fast

Credit utilization is the percentage of your available revolving credit currently in use. It is calculated two ways simultaneously: across all your cards combined, and on each card individually. Both affect your score.

What makes it uniquely valuable is that it carries no history. A late payment stays on your report for seven years; utilization is recalculated from scratch every time an issuer reports your balance, typically monthly. Pay a card down and the improvement appears on your next report. Nothing else in credit scoring responds that quickly.

  • Roughly 30% of a FICO score — second only to payment history at 35%
  • Calculated per card and across all cards
  • Recalculated monthly with no memory of past utilization
  • Under 30% is the common threshold; under 10% is where top scores sit

Going deeper

The statement date trick

Issuers report your statement balance to the credit bureaus, not your balance after you pay the bill. Someone who charges $3,000 a month and pays in full still reports $3,000 of utilization, because the statement closed before the payment posted.

Paying the balance down before the statement closing date — not the due date — causes a lower figure to be reported. For someone with high monthly spending relative to their limits, this alone can move reported utilization from 60% to under 10% without changing anything about how much they spend or carry.

Raising limits instead of paying down

Utilization is a ratio, so increasing the denominator works as well as decreasing the numerator. A credit limit increase from $20,000 to $30,000 on the same $6,000 of balances drops utilization from 30% to 20% instantly.

Most major issuers allow limit increase requests through their app, and many process them with a soft inquiry that does not affect your score. The caveat is behavioral rather than mathematical: a higher limit only helps if the additional room stays unused. If more available credit reliably becomes more debt, pay down instead.

  • Request increases through the issuer's app — many use a soft pull
  • Wait 6+ months between requests on the same card
  • Never close an unused no-fee card; its limit is doing useful work
  • A new card also raises total limit, but the hard inquiry and lower average age offset some benefit

Common mistakes

  1. 1

    Paying after the statement closes

    Issuers report the statement balance. Paying in full by the due date still reports high utilization if the statement closed first.

  2. 2

    Closing paid-off cards

    Removing a card's limit raises utilization on everything that remains and eventually shortens your credit history.

  3. 3

    Concentrating balances on one card

    Per-card utilization matters. One card at 90% hurts even when the overall ratio looks fine.

  4. 4

    Opening new cards right before a mortgage application

    The hard inquiry and reduced average account age arrive immediately; the utilization benefit takes a cycle to appear.

  5. 5

    Assuming 0% is optimal

    Reporting no balance on any card is marginally worse than a small reported balance. Leave one small charge to report.

Common questions

What is a good credit utilization ratio?

Under 30% is the widely cited threshold, but lower is better. Consumers with FICO scores above 800 typically report utilization between 1% and 9%. Interestingly, reporting exactly 0% across all cards is very slightly worse than reporting a small balance, because scoring models want to see accounts being used responsibly rather than dormant.

How quickly does utilization affect my credit score?

Typically within 30–60 days — as soon as your issuer reports the lower balance to the bureaus. It is the fastest-moving factor in credit scoring. Paying a card down before the statement closing date rather than the due date gets the improvement reported a full cycle earlier.

Does utilization matter on each card or just overall?

Both. FICO evaluates your aggregate ratio and your per-card ratios. One card at 95% will hurt even if your overall utilization is a comfortable 20%. If you are optimizing for a score before a mortgage application, spread balances so no single card is above 30% rather than concentrating them.

Should I close a credit card I do not use?

Usually not, if it has no annual fee. Closing it removes its limit from your utilization denominator, which raises your ratio across the remaining cards, and eventually shortens your average account age. Keep it open with a small recurring charge and autopay. If it carries a fee that is not earning its keep, ask the issuer to downgrade it to a no-fee card in the same family rather than closing it.

Do installment loans count toward utilization?

No. Utilization applies only to revolving credit — credit cards and lines of credit. Car loans, student loans and mortgages are installment debt, and their balances are evaluated separately and with much less weight. This is why paying off a car loan barely moves your score while paying down a card can move it substantially.
