# How is credit utilization calculated?

> **Entwurf.** Dieser Beitrag erfüllt die Redaktionsregel noch nicht vollständig und ist nicht indexiert.

Credit utilization is the reported balance divided by the credit limit. The balance that counts is the one on the statement date, not the one after your payment. Paying in full every month while putting a lot of spending on the card can therefore still show a high ratio. The figure changes monthly, faster than anything else in the report.


## At a glance

| Figure | What it means | How often it changes |
|---|---|---|
| Credit limit | the line granted on one account | rarely, on request or at the issuer's initiative |
| Reported balance | the balance on the statement date | monthly |
| Utilization per card | balance divided by that card's limit | monthly |
| Overall utilization | sum of balances divided by sum of limits | monthly |
| Payment on the due date | prevents interest | leaves the reported figure unchanged |
| Closing an account | removes its limit from the total | with the next cycle |

## What utilization measures

Credit utilization puts two numbers side by side, and both appear in the [credit report](/en/glossary/credit-report): the
reported balance of an account and that account's [credit limit](/en/glossary/credit-limit). The result is a ratio, and
from a lender's point of view the ratio answers one question only: how heavily somebody is
drawing on the lines granted right now.

Utilization belongs to the factor group of amounts owed, and the best known scoring vendor
gives that group a weight of 30 % for the general population. Only payment history weighs more, and payment history
cannot be improved quickly. Utilization, by contrast, changes with every reporting cycle and
hinges on a date that hardly anybody knows, which makes it the most practical lever in the whole
report.

Newcomers tend to equate utilization with debt, which it is not; it is a snapshot of one day's
balance against the line granted. For somebody who has just moved to the US from Germany, Austria,
Switzerland or anywhere else, the ratio has one more twist: with a short file and one or two cards, every
month's reported balance weighs more than it would in a long history.

## Which balance gets reported

### The statement date decides, not the payment date

A card account runs through two dates each month. On the **[statement date](/en/glossary/statement-date)** the issuer
closes the cycle, produces the statement and sends that day's balance to the credit
bureaus. By the **[due date](/en/glossary/payment-due-date)**, a few weeks later, the payment has to arrive for purchases to
stay free of interest.

The balance reported is therefore a balance from before the payment. Paying everything on
the due date prevents interest, but the figure already reported stays in the file: utilization
follows the first date, interest the second. Both dates and their
separate effects are laid out in
[What is the difference between the statement date and the due date?](/en/statement-date-vs-due-date).

The two dates produce the contradiction newcomers run into most often. Somebody has paid on time
and in full for years, runs a lot of spending across the card, and still shows a high ratio
month after month. Nothing is wrong and nothing is missing from the payment history; the
reporting date simply falls before the payment.

### Per card and across all cards

Utilization is calculated twice. Once per account, by dividing that account's reported
balance by its own limit, and once across all accounts, by dividing the sum of all balances
by the sum of all limits.

Both figures enter the assessment, and the two can be far apart. A single card close to its
limit stands out even when the total looks unremarkable, while one empty card does little when
the other lines are heavily used. So the card with the highest individual ratio comes down first,
and the total gets optimised afterwards.

### The limit is the other half of the fraction

Utilization can be lowered from two sides, a smaller balance or a larger limit. Both
routes lead to the same number on paper, with very different side effects.

A higher [credit limit](/en/credit-limit) lowers the ratio without any change in behaviour.
Whether a limit increase triggers a [hard inquiry](/en/glossary/hard-pull) is the issuer's decision, and the answer is
usually stated in the request form before anything is submitted. What such an inquiry does
to the file is covered in [Hard pull or soft pull](/en/hard-pull-vs-soft-pull).

Closing an account works in the opposite direction. The limit disappears from the total,
the spending stays, and overall utilization rises. With only a few accounts, a single
closure can push the ratio up sharply without anybody spending more. Where an [annual fee](/en/glossary/annual-fee) is
the reason for closing, [Cancel the card or downgrade it?](/en/cancel-or-downgrade) sets
out the alternative that keeps the limit in place.

## Three ways to lower the reported ratio

Three levers exist, and they differ a great deal in effort and side effects.

**Pay before the statement date.** This is the most effective route and the simplest. A payment a
few days before the cycle closes lowers the balance that gets reported, without changing
the regular payment rhythm.

**Spread the spending.** Two cards with moderate ratios look different from one maxed out
card next to an empty one, even when the total is identical. Spreading pays off mainly when
one account keeps hitting its limit, for example because a large recurring charge runs
through it.

**Raise the limit.** The lever with the largest effect and the most unpleasant side effect,
because some issuers review creditworthiness again. Before asking, find out whether a hard
inquiry will be made.

Overpaying is not one of the levers. A credit balance on the card is normally reported as
zero, never as a negative amount, so overpaying achieves nothing beyond a full
payment.

## What utilization is not

**Utilization is not debt.** The ratio describes a balance on one day, not money owed over
months. Somebody who pays in full every cycle has no debt at all, and may still show a high
reported ratio.

**Utilization has no memory.** Unlike a missed payment, which stays visible for years, the
ratio is reported fresh each month and replaces the previous one.

**Utilization is not a judgement on spending.** How much somebody spends is irrelevant to
the ratio, as long as the relation to the limit is fine. Heavy spending on a large line
stands out less than moderate spending on a small one.

## Worked example: three cards, one month

The figures are assumptions, and the currency does not matter; the ratio is the point.
Take a newcomer with three cards. Card A has a limit of 2,000, card B a limit of 6,000 and
card C a limit of 12,000, so the lines add up to 20,000. All regular spending of 1,800 a
month runs through card A, and cards B and C sit unused.

| | Everything on card A, paid on the due date | Same spending, paid before the statement date | Spending spread across all three cards |
|---|---:|---:|---:|
| Reported balance, card A | 1,800 | 200 | 400 |
| Reported balance, cards B and C | 0 | 0 | 1,400 |
| Utilization, card A | 90 % | 10 % | 20 % |
| Highest single card ratio | 90 % | 10 % | 20 % |
| Overall utilization | 9 % | 1 % | 9 % |
| Interest | none | none | none |

Running everything through card A is the trap. The overall ratio of 9 % looks harmless, yet one card reports
90 %, and that single card is what stands out. Nothing about the person's finances is
wrong; the problem is a small limit carrying all the spending up to the statement date.

One extra payment before the statement date fixes the problem. Spreading the spending fixes the
single card ratio as well, but leaves the overall figure unchanged.

In all three columns no interest is charged and the payment history is spotless. Paying early
manipulates nothing; the cardholder only chooses which balance gets reported.

## What to make of the thirty percent rule

Advice columns repeat a rule that utilization must stay below thirty percent. No official
basis for that line exists, and no scoring vendor describes it as a threshold.

What the vendors do describe is a sliding relationship: lower is better, all the way down.
A ratio of ten percent scores better than one of twenty nine, although both sit below the
supposed limit. Treating the rule as a threshold means stopping exactly where there is still
room to improve. As a rough warning mark the rule of thumb still works, since a ratio that stays
above it month after month means the lines are heavily used. As a target it fails.

## Where to read your own ratio

Your own utilization can be checked in three places, and they do not show the same
thing.

**On the statement.** The statement shows the balance on the statement date, which is
the very number that gets reported, and the limit usually sits right next to it.
Dividing one by the other gives the ratio the issuer passed on, without any app.

**In the credit report.** The report shows the last reported balance for each account,
and it exposes wrong limits. A limit reported too low drives the ratio up, and that error
can be disputed. How
the report itself is built is explained in
[How do I build a US credit report from scratch?](/en/how-us-credit-reports-work).

**In the issuer's app.** The app shows today's balance. For the report that figure is
irrelevant, but it is the right number to check a few days before the statement date.

Keeping the three views apart explains the most frequent confusion: the app shows a high
number, the report a low one, and both are correct because they describe different days.

## When it is not worth optimising

Three situations make fine tuning the ratio pointless:

- **No application in sight.** The ratio changes monthly and has no memory. Without an
  application in the foreseeable future, keeping it permanently low gains nothing.
- **An open missed payment.** A missed payment outweighs any ratio. While a delinquency is
  open, the attention belongs there.
- **Interest on the balance.** [Carrying a balance](/en/glossary/carrying-a-balance) from one cycle to the next costs interest,
  and that cost exceeds any benefit from a lower reported ratio. The numbers are in
  [When does interest arise on a credit card?](/en/carrying-a-balance).

On an empty file the whole question falls away, because without reported accounts there is no
utilization at all. How the scoring models weigh the ratio once it exists is compared in
[FICO or VantageScore: which number decides](/en/fico-vs-vantagescore).

## The most common mistakes

- **Taking the due date for the reporting date.** The statement date decides what gets
  reported, and the due date only decides about interest.

- **Watching only the overall ratio.** Every card is rated on its own too, and the highest
  single ratio stands out first.

- **Closing cards to tidy up.** Each closure removes limit from the total and raises the
  ratio, while an unused card without a fee costs nothing to keep open.

- **Not using the card at all.** A small, regularly reported balance usually scores better
  than an account without any activity.

- **Treating the thirty percent rule as a target.** Lower is better on a sliding scale, and no
  threshold exists.

- **Asking for a higher limit without checking the inquiry.** If the issuer makes a hard
  inquiry, a small improvement in the ratio is paid for with a new entry in the file.

## Several cards with the same issuer

Several cards with the same issuer are still several accounts in the file, each with its
own limit. Moving spending between them changes the individual ratios and leaves the total
where it was.

Some issuers allow limit to be moved from one card to another without a new [credit check](/en/glossary/credit-inquiry),
which defuses a single high ratio without shifting spending or risking an inquiry. Whether
an issuer offers that is written in its terms, not in its advertising.

## Frequently asked questions

### How do you calculate credit utilization?

Divide the reported balance by the credit limit and express the result as a percentage. The ratio is calculated for each card and for all cards together, and scoring models look at both.

### Which balance is reported to the credit bureaus?

The balance on the statement date, the day the issuer closes the billing cycle and produces the statement. A payment made after that day no longer changes the figure that has already been reported.

### Why is my utilization high if I pay my card in full every month?

Because the statement date falls between spending and payment. Heavy spending that is paid off only on the due date gets reported as a high balance every month, even though no interest is ever charged.

### Is the 30 percent utilization rule real?

The rule is a simplification without an official basis. Scoring models treat utilization as a sliding scale where lower is better throughout, and no threshold exists below which everything scores the same.

### Does asking for a credit limit increase help utilization?

A higher limit lowers the ratio for the same spending. Whether the request triggers a hard inquiry is the issuer's decision, and that answer belongs on the table before the request is sent.

### Is 0 percent utilization the best?

Not necessarily. Models usually rate a small, regularly reported balance better than none, because an account without any activity says little about how someone handles credit.

### Does utilization count per card or across all cards?

Both. A single card close to its limit stands out even when the overall ratio is low, and one empty card helps little when all the other lines are heavily used.

### How fast does lowering utilization improve a credit score?

With the next reporting cycle, which usually means within a month. That makes utilization the only major factor in the file that can be moved in the short term.

### Does closing a credit card raise utilization?

Yes, in most cases. Closing removes that card's limit from the total while spending stays the same, so the overall ratio goes up. With only a few accounts the effect is large.

### Does utilization apply to loans as well?

Not in the same way. For instalment loans the model looks at the remaining balance against the original loan amount, and that figure falls on schedule with every payment.
