No, your personal credit score doesn’t directly influence your business credit score. None of the three business credit reporting agencies (Dun & Bradstreet, Experian, and Equifax) use your personal score to calculate your business credit score. That being said, your personal credit may still affect your chances of getting business financing. Many, many lenders check your personal credit score as part of the loan approval process. So even though your personal credit won’t change your business credit, you should keep an eye on both scores.
