To calculate your credit utilization, divide your credit card balance by your credit limit and multiply by 100. Do it for each card and for all cards combined, because scoring models look at both. For example, a $450 balance on a $3,000 limit is 15% utilization. A good rule of thumb is to keep utilization under 30%, and under 10% if you want the strongest scores. To find your ideal balance, multiply each card’s limit by your target percentage — on a $5,000 limit, that’s $1,500 at 30% and $500 at 10%. Then pay down to that amount before your statement closes, since that’s usually the balance that gets reported.

This guide walks you through the calculation step by step, gives you a ready-made table of target balances, and shows you how to hit your goal every month.

A simple calculation that can make a big difference to your score.

Key takeaways

• Utilization = balance ÷ credit limit × 100.
• Calculate it for each card and for all cards combined.
• Under 30% is good; under 10% is associated with the highest scores.
• Your target balance = credit limit × target percentage.
• The balance on your statement closing date is usually what’s reported.
• Pay before the statement closes to lower reported utilization.

The Utilization Formula

The formula in one line.

Utilization (%) = Balance ÷ Credit limit × 100

Example: $450 ÷ $3,000 = 0.15 → 15%

How to Calculate Your Utilization

Five steps to find your utilization.

Step 1: List every card

Include bank cards, store cards, and any other revolving credit lines. Leave out installment loans like car loans and mortgages.

Step 2: Write down each statement balance

Use the balance from your most recent statement — that’s usually what your issuer reports to the credit bureaus.

Step 3: Write down each credit limit

Find it on your statement or in your card’s app.

Step 4: Divide balance by limit

Do this for each card, then add all balances and all limits together and divide again for your overall utilization.

Step 5: Compare to your targets

Under 30% is good. Under 10% is better. Watch for any single card that’s much higher than the rest.

Worked Example

Overall utilization can hide a maxed-out card.

Overall utilization is 22.5% — under 30%. But Card B is at 90%, which can still hold your score back. Paying Card B down to $200 or less would bring it to 10% and overall utilization to about 6.5%.

Target Balances by Credit Limit

Your target balance for common limits.

To find your own target: credit limit × 0.30 for the 30% ceiling, or × 0.10 for the 10% target.

How Much to Pay to Hit Your Target

Payment needed = Current balance − Target balance

Example: Your card has a $2,000 limit and a $1,100 balance. Your 10% target is $200. You need to pay $900 before the statement closes to report $200.

To find the payment needed for an overall target:

Payment needed = Total balances − (Total limits × target percentage)

Example: Total balances $2,250, total limits $10,000, target 10% → $2,250 − $1,000 = $1,250.

Timing: When to Pay

Card issuers usually report your balance around your statement closing date, not your due date. If you pay in full on the due date, your statement balance may still be reported. To lower reported utilization:

• Find your statement closing date on your statement or in your app
• Make a payment a few days before it closes
• Pay the remaining balance by the due date

Many people pay twice a month to keep reported balances low.

What About 0% Utilization?

Paying every card to exactly $0 before statements close is fine, but some scoring models slightly favor a small reported balance on one card over zero on every card. The difference is small. A common approach is to let one card report a small balance and pay it in full by the due date — you never pay interest.

Special Cases

• New cards add available credit, which can lower overall utilization, but also add an inquiry
• Closed cards remove available credit, which can raise utilization
• Authorized user cards may count toward your utilization
• Charge cards without preset limits may be treated differently by scoring models
• Credit limit decreases raise your utilization even if your balance doesn’t change

Calculator Worksheet

Use this worksheet each month:

Fill in balances and limits, calculate utilization and targets, then note how much to pay before each statement closes.

Example: Getting Ready for a Mortgage

Here’s an illustrative example. A borrower planning to apply for a mortgage in three months has:

• Card A: $3,200 balance, $4,000 limit (80%)
• Card B: $900 balance, $6,000 limit (15%)
• Total: $4,100 on $10,000 (41%)

Her goal: under 10% overall and on each card. She needs:

• Card A down to $400 → pay $2,800
• Card B down to $600 → pay $300
• New total: $1,000 on $10,000 → 10%

She pays Card A in two installments over the next two statements and pays Card B before its next closing date. By the time she applies, her reported utilization is under 10%.

Common Calculation Mistakes

• Using your available credit instead of your limit
• Leaving out store cards or lines of credit
• Using your current balance when your statement balance will be reported
• Forgetting authorized user accounts that appear on your report
• Only calculating overall utilization and missing a single maxed-out card

Utilization and Your Credit Score

Utilization is part of the “amounts owed” category, which makes up 30% of your FICO score. Because most scoring models look at current utilization, changes can show up quickly — often within one billing cycle. Some newer models also consider how your balances trend over time, rewarding people who consistently pay down balances.

How to Keep Utilization Low Every Month

• Pay before your statement closes
• Pay twice a month if you use your card heavily
• Spread spending across cards so no single card gets too high
• Ask for credit limit increases on long-standing cards
• Keep old cards open to preserve available credit
• Set balance alerts in your card apps

When Utilization Matters Most

Utilization matters most in the months before you apply for:

• A mortgage
• An auto loan
• A new credit card
• An apartment

Plan to have low reported balances for at least one or two statement cycles before you apply.

Utilization for Business Owners

If you use personal cards for business expenses, those balances count toward your personal utilization. Consider a separate business card, and check whether it reports to your personal credit. Keeping business spending off personal cards makes your utilization — and your score — more predictable.

Utilization for Authorized Users

If you’re an authorized user on someone else’s card, its balance and limit may appear on your report and affect your utilization. A high balance on that card can lower your score even if you never use it. If that happens, talk to the primary cardholder or ask to be removed.

Keep Perspective

Utilization is one of the fastest-moving parts of your score — which means it’s one of the easiest to fix. A single month of lower reported balances can make a real difference. Pair low utilization with on-time payments, and your score has the best foundation it can have.

Quick Reference: Formulas

How Utilization Changes After Common Events

Example: The Effect of a Limit Increase

Here’s an illustrative example. A borrower has a $600 balance on a $2,000 limit — 30%. She asks for a limit increase and is approved for $4,000 without a hard inquiry. With the same $600 balance, her utilization drops to 15%. If she keeps spending the same amount, her utilization stays lower going forward.

Example: The Effect of Closing a Card

A borrower has two cards: $1,500 balance on a $5,000 limit and $0 on a $5,000 limit. Overall utilization is 15%. If he closes the card with no balance, his total limit drops to $5,000 and his utilization jumps to 30% — without spending anything more.

Utilization Myths

• “Paying on the due date keeps utilization low.” The statement balance is usually what’s reported.
• “30% is the best number.” It’s a ceiling, not a target.
• “Utilization has a long memory.” In many models, it reflects current balances only.
• “I need to carry a balance.” Paying in full is best.

A Month-by-Month Utilization Routine

• At the start of each month: note each card’s statement closing date
• A week before each closing date: check balances and calculate utilization
• A few days before closing: pay down to your target
• By the due date: pay the rest of the statement balance
• Once a month: check your score from the same source to see the effect

Building a Utilization Target Into Your Budget

If you use cards for everyday spending, set a monthly spending cap per card based on your target utilization. For example, if your card has a $3,000 limit and your target is 10%, try to have no more than $300 reported. If you spend more, pay part of it before the statement closes.

Where to Find Your Statement Closing Date

• On your monthly statement, usually near the top
• In your card’s app or online account
• By calling the issuer

The closing date is typically about three weeks before the due date. Write each card’s closing date in your calendar and set a reminder a few days before.

Using a Spreadsheet as Your Calculator

If you’d like to track utilization over time, a simple spreadsheet works well:

• Column A: card name
• Column B: statement balance
• Column C: credit limit
• Column D: utilization = B ÷ C × 100
• Column E: 10% target = C × 0.10
• Column F: payment needed = B − E (if positive)

Add a total row, and update it each month before your statement closing dates.

Keep It Simple

You don’t need to calculate utilization down to the decimal every month. A simple habit covers most of it: know your closing dates, pay balances down before they close, and keep every card well under its limit. Use the formulas in this guide when you’re preparing for a big application or trying to understand a score change.

Utilization Goals by Situation

Frequently Asked Questions

How do I calculate credit utilization?

Divide your balance by your credit limit and multiply by 100. Do it for each card and for all cards combined.

What’s a good credit utilization ratio?

Under 30% is good. Under 10% is associated with the highest scores.

Does utilization include loans?

Revolving utilization includes credit cards and lines of credit. Installment loans are considered separately.

When is utilization calculated?

Scores use the balances reported to the bureaus, usually around your statement closing date.

Should I pay my card to zero?

Paying to zero is fine. Some models slightly favor a small balance on one card, but the difference is small.

Can a credit limit increase lower my utilization?

Yes, if your balance stays the same. Ask whether the request involves a hard inquiry.

How fast does lowering utilization help my score?

Often within one billing cycle, once the lower balance is reported.

Should I count my car loan in utilization?

No. Revolving utilization includes credit cards and lines of credit. Installment loans are considered separately.

What if my limit changed recently?

Use your current limit. If an issuer lowered it, your utilization may have gone up.

Does utilization affect all three bureau scores?

Yes, for each bureau where the card is reported.

Is there a perfect utilization number?

There’s no single perfect number, but under 10% is associated with the highest scores, and a small balance on one card is often slightly better than zero on all.

Do store cards count toward utilization?

Yes. Store credit cards are revolving accounts and count.

What if I carry a balance I can’t pay down quickly?

Focus on the card closest to its limit first, avoid new charges, and keep every payment on time.

How often should I calculate my utilization?

Monthly, especially before your statement closing dates and before big applications.

Does paying off my card mid-month help?

Yes, if it’s before the statement closes. That lowers the balance that gets reported.

Is there an app that calculates utilization?

Many card issuers and free credit score services show your utilization. You can also use the worksheet in this guide.

Does a 0% APR card affect utilization?

Yes. A balance on a 0% APR card still counts toward utilization, even without interest.

Do balance transfers change utilization?

They move balances between cards. Overall utilization may stay the same, but per-card utilization changes, and a new card adds available credit.

Can I lower utilization without paying down debt?

Yes, by increasing available credit, such as through a limit increase. Paying down balances is usually the more reliable approach.

Does a secured card’s deposit affect utilization?

The deposit usually sets your credit limit, which is used to calculate utilization.

Does utilization matter if I pay in full every month?

Yes, because the reported statement balance is used to calculate utilization. Pay before the statement closes to keep it low.

Is utilization calculated the same way by FICO and VantageScore?

Both use the same basic calculation, although they weigh it slightly differently.

Should I use my card less to lower utilization?

You can, or you can keep using it and pay before the statement closes.

Does utilization include cards with a $0 balance?

Yes. Their limits count toward your total available credit, which lowers overall utilization.

What if my card has no preset spending limit?

Scoring models may treat these cards differently. Paying in full each month is the safest approach.

Can I lower utilization by moving balances to a new card?

Opening a new card adds available credit, which can lower overall utilization, but it also adds an inquiry and a new account. Paying down balances is usually the better long-term strategy.

Does utilization affect mortgage approvals?

Utilization affects your score, which affects mortgage pricing. Lenders also look at your total debts when calculating debt-to-income ratio.

How low should I go before a big application?

Under 10% overall and on each card is a strong target for the months before you apply.

What’s the difference between utilization and debt-to-income ratio?

Utilization compares your card balances to your credit limits and affects your score. Debt-to-income compares monthly debt payments to income and is used by lenders separately.

Does paying off a card affect my utilization immediately?

The change shows up after the issuer reports the new balance, usually after the next statement closes.

Should I keep a card open just for its limit?

If it has no annual fee, keeping it open helps your available credit and utilization.

Can I use this calculation for a line of credit?

Yes. Revolving lines of credit are included in utilization calculations.

Is utilization the same as my credit usage in my app?

Many apps show a utilization percentage based on your current or reported balances. Check whether it uses statement balances.

Why is my calculated utilization different from my app?

Your app may use different dates or include accounts you left out. Check which balances and limits it uses.

Can I calculate utilization for just one bureau?

Yes, using the balances and limits shown on that bureau’s report. Some cards may report to only one or two bureaus.

Does a credit freeze affect utilization?

No. Freezes don’t affect your score or utilization.

What if a card reports the wrong limit?

A missing or wrong limit can make utilization look higher. Dispute it with the bureau and the issuer.

Does utilization matter for VantageScore too?

Yes. VantageScore also weighs utilization heavily.

Can high utilization hurt even if I pay on time?

Yes. Utilization is separate from payment history, so high reported balances can lower your score even if you never miss a payment.

Is it better to pay down one card or spread payments?

Paying down the card with the highest utilization first often helps most, since per-card utilization matters.

The Bottom Line

Your credit utilization is simple to calculate: balance divided by limit, times 100 — for each card and in total. Set a target, calculate your ideal balance for each card, and pay down to it before your statements close. It’s one of the fastest ways to improve your credit score.
