Keep in mind that the information on your credit reports may not change every time you update them on Credit Karma. It usually takes about 30 days for creditors to report new information (like new balances or payment activity) to the credit bureaus, and the frequency of updates can vary by creditor.
In this case, Credit.com wins due to the accuracy of the information. This is not Credit Karmaâs fault, however. Credit Karma does have a strong plus: this site provides an exact credit score while Credit.com offers only ranges.
