No. Using Credit Karma does not lower your credit score.
When Credit Karma gets your credit score, we request the information on your behalf. This is known as a soft inquiry. Soft inquiries do not impact your score because you are using it as personal reference and not to apply for a new line of credit.
Hard inquiries, on the other hand, can influence your credit score. They’re typically placed on your report when you apply for a new line of credit.
