Your total credit limit is the combined maximum borrowing capacity across all of your open revolving credit accounts. Add every card and line of credit’s ceiling together and you have the number. It matters because it is the denominator of your credit utilization ratio, which sits inside the “amounts owed” category and accounts for roughly 30 percent of a typical FICO score.1myFICO. How Owing Money Can Impact Your Credit Score
How to Add It Up
The math is straightforward. If you carry a Visa with a $10,000 limit, a store card with a $3,000 limit, and a personal line of credit at $7,000, your total credit limit is $20,000. Three cards at $5,000, $8,000, and $12,000 give you $25,000.
Each account’s limit appears on your monthly statements, in your issuer’s mobile app, and on your credit reports. The three major bureaus — Equifax, Experian, and TransUnion — each list the credit limit for every open revolving account. You can pull free weekly reports from AnnualCreditReport.com, the federally authorized source.
What Counts and What Doesn’t
Only revolving accounts, meaning those with a reusable credit line, factor into the total:
- Standard credit cards from banks or credit unions (Visa, Mastercard, American Express, Discover).
- Store credit cards, which may be usable only at a specific merchant or merchant group.
- Personal lines of credit, usually unsecured and often carrying a variable rate.
- Home equity lines of credit (HELOCs), which are secured by your home’s equity.
Installment loans do not count. A mortgage, auto loan, student loan, or personal loan involves a fixed sum repaid on a set schedule, so there is no revolving line to add in.
Why the Number Matters
Divide your total revolving balances by your total credit limit and you have your utilization rate. Owe $4,000 against a $20,000 total and you are at 20 percent.2myFICO. How FICO Scores Look at Credit Card Limits Lower is generally better. People with FICO scores in the 800–850 range carry an average utilization of about 7 percent, while those in the 580–669 range average around 61 percent.3Experian. What Is a Credit Utilization Rate?
The commonly cited 30 percent guideline is not a bright line. It is roughly the point where higher utilization starts producing a more pronounced drag on your score. Single digits are ideal.
Zero is not better than a very low number. Carrying no balance at all usually means you aren’t using the cards, which generates no payment history. The lack of activity can also prompt issuers to cut your limit or close the account, both of which shrink your total credit limit.4Experian. Is 0% Utilization Good for Credit Scores
Scoring models look at per-card utilization too, not just the overall figure. A single card maxed to 100 percent can hurt your score even when the aggregate rate is low.3Experian. What Is a Credit Utilization Rate? Spreading spending across several cards keeps both numbers down.
What Shrinks Your Total
Closing a Card
When you close a credit card, that card’s limit disappears from your total. Any balance you carry on other cards suddenly represents a bigger share of a smaller number. Say your total limit is $30,000 and you owe $3,000 (10 percent utilization). Close a card with a $10,000 limit and the total drops to $20,000. The same $3,000 balance now puts you at 15 percent.
Inactivity
A limit you never use is not guaranteed to stay. Issuers may reduce the limit or close the account after an extended stretch of no activity, often around 12 months or more. A small purchase every few months keeps the account active.
If your issuer does reduce a limit on a standard credit card, it must give at least 45 days’ advance notice before charging an over-the-limit fee or imposing a penalty rate tied to the new, lower limit.5eCFR. 12 CFR 226.9 – Subsequent Disclosure Requirements The notice protects you from penalties on a limit you didn’t know had changed; it does not require advance notice of the reduction itself.
What Grows Your Total
Raising the total lowers your utilization without requiring you to pay anything down. Several approaches work:
- Request an increase from a current issuer, usually through the app or website. Approvals are more likely once the account has been open for several months and your income has risen since opening.6Experian. When’s a Good Time to Request a Credit Limit Increase
- Update your income on file. Issuers can use the figures you provide and may not independently verify them, so reporting a raise through the app can prompt an automatic increase.7Consumer Financial Protection Bureau. 1026.51 Ability to Pay
- Wait for an automatic increase. Many issuers periodically review accounts and raise limits for cardholders who pay on time and keep utilization low.
- Open a new card. Each new account adds its own limit to your total, which can offset the temporary score dip from the application if the new limit is large enough.
Being Added as an Authorized User
If someone adds you as an authorized user, that card’s full limit typically appears on your report and counts toward your total. The effect can be meaningful. Suppose you carry $500 and $800 balances on cards with $2,000 and $3,000 limits, and someone adds you to a card with a $10,000 limit and a $1,000 balance. Your total utilization drops from about 26 percent to roughly 15 percent.8Experian. Will Being an Authorized User Help My Credit?
The reverse applies too. If the primary cardholder runs the balance up, that balance lands on your report. You have no control over their spending, so the strategy carries real risk if their habits are unpredictable.
Watch for Hard Inquiries
Requesting a limit increase or applying for a new card may trigger a hard inquiry. A hard inquiry typically costs fewer than five points and affects your score for about a year, though it stays visible on the report for two.9myFICO. Do Credit Inquiries Lower Your FICO Score? Some issuers use only a soft inquiry for limit-increase requests, which has no score impact. If you aren’t sure which your issuer will run, call the number on the back of the card and ask before submitting.
Going Over a Limit
Exceeding the limit on a single card spikes that card’s utilization and can trigger fees and higher interest. Federal law restricts what issuers can charge without your permission. A card issuer cannot assess an over-the-limit fee unless it first gave you a clear notice describing the fee, obtained your affirmative consent (known as “opting in”), and confirmed that consent in writing or electronically.10eCFR. 12 CFR 226.56 – Requirements for Over-the-Limit Transactions If you never opted in, the issuer may still approve the transaction but cannot charge a fee for doing so.
Fees are not the only risk. The opt-in notice must also disclose any increased rate that could result from an over-the-limit transaction, and penalty rates are often significantly higher than the standard rate on the account.10eCFR. 12 CFR 226.56 – Requirements for Over-the-Limit Transactions If you have not opted in, many issuers will decline the transaction at the register rather than process it.
