why my credit score decreased

Your credit score can decrease for several key reasons related to how you manage your debt. These factors are closely monitored by credit bureaus:

• Missed or late payments on loan EMIs or credit card bills are a primary cause, as payment history is a major factor.
• A high credit utilization ratio, meaning you are using more than 30% of your total available credit limit.
• Applying for multiple new loans or credit cards in a short period, which results in multiple 'hard inquiries.'
• Closing an old credit account, which can shorten your overall credit history and increase your utilization ratio.
• An error or incorrect information on your credit report that you need to dispute.
