What is Credit Utilization Ratio?

Let’s start with the basics: what exactly is credit utilization ratio? In simple terms, your credit utilisation ratio is the percentage of your available credit that you’re currently using. 

It’s calculated by dividing the total amount of credit you’re using by the total amount of credit available to you, then multiplying by 100 to get a percentage.

For example, if you have a credit card with a £5,000 limit and you currently have a balance of £1,000, your credit utilization ratio would be 20% (£1,000 ÷ £5,000 × 100).

Why Does Credit Utilization Ratio Matter?

You might be wondering why this seemingly obscure ratio is such a big deal. 

Well, your credit usage ratio is actually a key factor in determining your creditworthiness.

Lenders use it to assess how responsibly you manage credit and to predict the likelihood that you’ll be able to repay any new credit they extend to you.

In the UK, credit scores are used by lenders to evaluate your creditworthiness when you apply for loans, credit cards, or mortgages. 

Your credit utilisation ratio is a significant component of your credit score, so keeping it low can have a positive impact on your overall creditworthiness.

Factors That Influence Your Credit Utilization Ratio

Your credit utilization ratio can fluctuate for various reasons, including:

Credit Card Balances: The most significant factor affecting your credit utilization ratio is your credit card balances. Keeping these balances low relative to your credit limits can help maintain a healthy ratio.

Credit Card Balances

Credit Limit Increases or Decreases: If your credit card issuer increases your credit limit, your credit utilization ratio will decrease, assuming your balances remain the same. Conversely, if your credit limit decreases or you close a credit account, your ratio may increase.

New Credit Accounts: Opening new credit accounts can impact your credit utilization ratio, especially if those accounts come with significant credit limits.

Paying Off Debt: Paying off debt can lower your credit utilization ratio, potentially boosting your credit score in the process.

Tips for Managing Your Credit Utilization Ratio

Now that you understand what credit utilization ratio is and why it matters, let’s explore some practical strategies for managing it effectively:

Monitor Your Credit Card Balances Regularly: Make it a habit to check your credit card balances frequently, ideally at least once a month. This way, you can keep track of your spending and ensure that your balances stay within a reasonable range.

Pay Your Balances in Full Whenever Possible: Paying off your credit card balances in full each month is one of the most effective ways to keep your credit utilization ratio low. It also helps you avoid costly interest charges, saving you money in the long run.

Consider Requesting a Credit Limit Increase: If you’re consistently using a high percentage of your available credit, you might consider asking your credit card issuer for a credit limit increase. Just be sure to use this additional credit responsibly and avoid the temptation to overspend.

Use Multiple Credit Cards Wisely: Instead of maxing out one credit card, consider spreading your purchases across multiple cards. This can help keep your individual credit utilization ratios lower, which can be beneficial for your overall credit score.

Avoid Closing Unused Credit Accounts: While it may be tempting to close old credit accounts that you no longer use, doing so can actually harm your credit utilization ratio by reducing your available credit. Unless there are compelling reasons to close an account (such as high fees), it’s generally best to keep it open.

Pay Attention to Timing: Keep in mind that credit card balances are typically reported to the credit bureaus once a month, usually on your statement closing date. Try to pay down your balances before this date to ensure that your credit utilization ratio is as low as possible when it’s reported.

Additional Strategies for Managing Credit Utilization Ratio

Let’s delve even deeper into strategies and tactics for mastering your credit utilization ratio:

Keep Old Accounts Open: The age of your credit accounts is an essential factor in your credit score calculation. Closing old accounts can shorten your credit history and potentially lower your credit score. Even if you don’t use an old credit card anymore, consider keeping it open to maintain a longer credit history and improve your credit utilization ratio.

Set Up Balance Alerts: Many credit card issuers offer the option to set up balance alerts, notifying you when your balance approaches a certain threshold. Take advantage of this feature to stay informed about your credit card balances and avoid unintentionally increasing your credit utilization ratio.

Utilize Balance Transfer Offers Wisely: If you’re struggling with high credit card balances and want to lower your credit utilization ratio, a balance transfer offer may be worth considering. This involves transferring existing credit card balances to a new card with a lower interest rate or promotional period. However, be mindful of any balance transfer fees and ensure that you can pay off the transferred balance before the promotional period ends.

Keep Credit Utilization Low Across All Accounts: While it’s essential to maintain a low credit utilization ratio on each individual credit card, don’t overlook your overall credit utilization across all your accounts. Aim to keep your total credit utilization ratio, including all credit cards and lines of credit, below 30% to maximize your credit score potential.

Regularly Review Your Credit Report: Your credit report contains information about your credit accounts, balances, and payment history, which can affect your credit utilization ratio. Regularly review your credit report from all three major credit bureaus (Experian, Equifax, and TransUnion) to ensure that the information is accurate and up to date. If you notice any errors or discrepancies, dispute them promptly to prevent them from negatively impacting your credit score.

Seek Professional Advice if Needed: If you’re struggling to manage your credit utilization ratio or facing financial challenges, don’t hesitate to seek professional advice. Credit counselors and financial advisors can provide personalized guidance and strategies to help you improve your credit score and achieve your financial goals.

What is a Credit Utilization Ratio?

A credit utilization ratio is the percentage of your total available revolving credit that you are currently using. 

It is calculated by dividing your total outstanding revolving balances by your total credit limits across all revolving accounts.

How is it Calculated?

To calculate your credit utilization ratio:

  • Add up the outstanding balances on all your revolving credit accounts (credit cards, lines of credit, etc.)
  • Add up the credit limits on all those revolving accounts
  • Divide the total balances by the total credit limits
  • Multiply by 100 to get the percentage

What is an Ideal Credit Utilization Ratio?

Experts generally recommend keeping your credit utilization ratio below 30%, and ideally between 20-25%. 

A ratio above 30% may negatively impact your credit scores.

However, a 0% ratio is also not ideal as lenders want to see you can responsibly use credit.

How Does it Affect Credit Scores?

Your credit utilization ratio accounts for a significant portion of your credit scores, often the second most important factor after payment history. 

A high ratio suggests you are overextended and may struggle to repay new credit, while a low ratio shows responsible credit management.

How to Improve Credit Utilization Ratio?

To improve your ratio, pay down existing revolving balances as much as possible. 

You can also request a credit limit increase from your lenders, which would increase your total available credit and lower the utilization percentage.
