Understanding the 30% Rule
The 30% rule is a widely recommended guideline in personal finance. It suggests that you should aim to use no more than 30% of your total available credit limit at any given time. This percentage is known as your Credit Utilisation Ratio (CUR). To calculate
it, simply divide your total outstanding credit card balance by your total credit limit. For instance, if you have a total credit limit of ₹1 lakh across all your cards and your current outstanding balance is ₹25,000, your CUR is 25%. Financial experts agree that keeping this ratio below 30% is ideal for maintaining a healthy credit profile.
How Credit Utilisation Impacts Your CIBIL Score
Credit bureaus like TransUnion CIBIL use several factors to calculate your three-digit score, which ranges from 300 to 900. While your payment history is the most important component, your Credit Utilisation Ratio is the second biggest factor and carries significant weight. A high CUR suggests to lenders that you might be overly reliant on credit to manage your expenses, which can be seen as a sign of financial stress. This perception increases your risk profile in their eyes, potentially leading to a lower CIBIL score. Conversely, a low utilisation ratio demonstrates that you manage your finances responsibly without maxing out your available credit, which positively impacts your score.
What Happens If You Exceed 30%?
Exceeding the 30% threshold, especially consistently, can negatively affect your CIBIL score. If your utilisation climbs towards 50% or higher, lenders may view this as a red flag, making it harder to get approved for new loans or credit cards. However, the impact isn't permanent. Your CUR is a dynamic figure that credit bureaus update based on the latest information from your lenders. If you have a high utilisation one month but pay down the balance the next, your ratio will drop, and your score can recover relatively quickly. An occasional spike, for a large planned purchase for example, is less damaging than maintaining a consistently high balance month after month.
Simple Ways to Keep Your Utilisation Low
Managing your CUR doesn't mean you have to stop using your credit cards. Instead, it’s about smart management. One effective strategy is to make multiple payments throughout the month instead of waiting for the bill. By paying down your balance before the statement is even generated, you can ensure a lower utilisation figure is reported to the credit bureaus. Another approach is to request a credit limit increase from your card issuer. A higher limit will automatically lower your utilisation ratio, assuming your spending stays the same. If you have multiple cards, spreading your expenses across them can also prevent any single card from having a very high utilisation rate.
A Holistic View of Your Credit Health
While keeping your CUR below 30% is a powerful tool, it's only one part of building a strong CIBIL score. The most critical factor remains your payment history—making all your EMI and credit card payments on time, every time, is non-negotiable. Other elements that influence your score include having a healthy mix of credit (like secured loans and unsecured cards), the length of your credit history (older accounts are generally better), and avoiding too many applications for new credit in a short period. Regularly checking your CIBIL report for errors is also a crucial habit for maintaining good financial health.
