Credit Karma updates credit scores and credit report information typically every 7 days (weekly). The updates come mainly from TransUnion and Equifax, and you can see changes as often as once a week when you log in. Recently, Credit Karma has started checking your credit reports daily for any changes, allowing for potentially more frequent updates if there are new data reported by the credit bureaus. However, the actual changes to your credit report from creditors can take up to 30 to 45 days to be reflected on Credit Karma because it depends on when creditors report to the credit bureaus. In summary, while Credit Karma checks for updates daily now, users usually see updates to their credit score and report information weekly, with actual data from lenders sometimes delayed by a month or more.
