Answer: Payment history

## FICO Score Weighting Explanation In the FICO credit scoring model, the factors are weighted as follows: - **Payment History (35%)** - Highest weight - Amounts Owed (30%) - Length of Credit History (15%) - New Credit (10%) - Credit Mix (10%) **Payment history** carries the highest weight at 35% because it demonstrates a borrower's reliability in meeting their financial obligations. This includes: - On-time payments - Late payments - Collections - Bankruptcies **Type of credit used** (credit mix) represents only 10% of the score. **Number of hard credit inquiries** falls under "New Credit" which represents only 10% of the score. Therefore, payment history is the most significant factor in determining a FICO score.
