how often is the credit score updated?

Answer 1

its not 'updated'. It changes when something effects it (i.e. credit card application or bank loan). In fact, if you ever found a mistake on your credit report, it is extremely hard to 'update' it.

Answer 2

Credit score is calculated anew every time it is requested. The "update" is to the underlying credit report and that is updated everytime a report is made to the monitoring agencies

Answer 3

I think credit score updated when you apply for a loan or if you requested to Equifax to check for status of your record.
