Credit scores change over time. Depending on your financial situation, the frequency of changes can vary. It is calculated by information in your credit reports. You must update it whenever there are changes. Your credit report provides information about credit accounts, payment history and credit limits, as well as recent requests for credit.
Information reported to the credit bureaus
Credit bureaus often receive information from creditors, card issuers, or other companies. This can cause credit scores to change. These companies are legally required by law to provide the bureaus with accurate information within a given time. The bureau then calculates your score on the basis of the most recent information.
You can dispute credit reports that you believe are inaccurate. The letter you send must contain a copy to the creditor indicating the dispute. The dispute process may take 30 to 90 days. Most states will give you a copy of your credit report after the dispute process is complete.

Late payments
Late payments can damage your credit score. Although you might not be able avoid late fees forever there are some ways to get around them. To avoid them, pay your bills on schedule. Late payments are reported to the credit bureaus at least 30 days after the due date. This gives you time to make up the missed payments. Late payments may also lead to an increase in your interest rate or a reduction of credit available.
Late payments can have a different impact on your score depending on how long it has been delinquent. Your score will drop significantly if your payment is late for more than 30 days.
For hard inquiries
The number of hard inquiries you have on your credit report may be one of the biggest concerns that you face. While they may not be as significant in determining your credit score, they play a major role in assessing how likely you are to repay debts. Your income and payment history are all factors that lenders look at when pulling your credit card report. Hard inquiries on your credit reports can indicate that your financial situation is severe. If this happens, you could run a greater risk of defaulting.
One inquiry can bring down your credit score five points. Two or more hard inquiries can reduce your credit score by 10 points. Additionally, those with six or fewer recent hard inquiries are eight to one more likely that they will file for bankruptcy. Good news: Most people don’t need so many inquiries to negatively impact their scores.

Lenders report account and payment information
Credit scores are updated monthly when new information about creditors is submitted to credit bureaus. However, some lenders report information more often than others. You might not see a debt on your credit card report immediately if you pay it off. This is because it could take anywhere from 30 to 60 business days before the payment appears on your credit file.
Lenders send account and payment information to the credit agencies at least once each month. However, this may vary. Lenders may report to one or more bureaus each month, while others might report to all three. Most lenders report account information and payment information every month to the major credit agencies.
