Most small-business owners are surprised to learn how much personal credit drives their business loan options. For loans under roughly $500K, personal FICO is one of the most important inputs. Business credit (Dun & Bradstreet's PAYDEX, Experian Intelliscore, Equifax Business) matters but plays a supporting role until the business is large enough that lenders underwrite it as a standalone entity.
Why personal credit dominates small-deal underwriting
Owners of 20%+ in a small business are personally guaranteeing the loan in nearly all structures. Personal FICO is the cheapest, most predictive piece of data the lender has. Most non-bank lenders, MCA/RBF funders, and the SBA all check personal credit (typically a tri-merge or a single-bureau pull).
Common FICO thresholds: 600+ for many non-bank short-term products, 650–680+ for SBA and bank lines, 720+ for the most competitive pricing.
When business credit actually matters
Business credit becomes meaningful when (1) the business is borrowing in its own name without a personal guarantee, which is rare in small business, (2) the business is applying for trade credit with vendors, (3) the business is applying for a business credit card with a corporate program, or (4) the business is large enough that a separate business credit pull is part of the lender's process.
How to build business credit
Establish a Dun & Bradstreet D-U-N-S number (free; required for many programs). Open accounts with vendors who report to the business credit bureaus (not all do). Pay early when possible — D&B's PAYDEX actually rewards early payment, not just on-time. Open a business credit card under the business EIN and use it.
