What Is a FICO Score?
Your FICO score is a number between 300 and 850 that summarizes your credit risk — the likelihood that you will repay a debt as agreed. It is calculated by Fair Isaac Corporation using data from your credit report. Most major lenders use FICO scores to make lending decisions, including banks, mortgage lenders, auto dealerships, and credit card companies. Scores above 670 are considered good; above 740 is very good; above 800 is exceptional.
Factor 1: Payment History — 35%
This is the biggest single factor. Every on-time payment strengthens it; every late payment or collection damages it. Even one missed payment can drop your score 60–110 points. The damage is worst for newer accounts and for people with otherwise clean files. Strategy: Set autopay for every account, minimum payment at least, and never miss a due date — ever.
Factor 2: Credit Utilization — 30%
This is the percentage of your available revolving credit that you are currently using. If you have a $10,000 total credit limit and carry $7,000 in balances, your utilization is 70% — which seriously hurts your score. The sweet spot is under 10% total utilization. Under 30% is acceptable. Over 50% starts causing real damage. Strategy: Pay down balances before your statement closing date (not just the due date) so the lower balance is what gets reported.

Factor 3: Length of Credit History — 15%
FICO looks at the age of your oldest account, the age of your newest account, and the average age of all accounts. The longer your credit history, the better. This is why closing old credit cards hurts you — it lowers the average age of your accounts and potentially removes your oldest account. Strategy: Keep old accounts open even with zero balance, especially ones with no annual fee.
Factor 4: Credit Mix — 10%
FICO rewards diversity. A mix of revolving credit (credit cards) and installment loans (auto, mortgage, personal loan, credit builder loan) scores better than having only one type. This is why adding a credit builder loan while you only have credit cards — or vice versa — can add points quickly. Strategy: Add the account type you do not currently have. If you only have cards, add a credit builder installment loan.
Factor 5: New Credit — 10%
Every time you apply for new credit and a lender does a hard inquiry, your score dips slightly. Opening multiple new accounts in a short period also reduces your average account age. FICO sees this as a risk signal. Strategy: Space out credit applications. If you are rebuilding, focus on one or two credit builder products and avoid applying for new cards until your score is above 650.
The Big Picture
Most people underestimate how much leverage they have over their score. Factors 1 and 2 together make up 65% of your score — and both are largely within your control right now. Factors 3 and 4 can be improved with credit builder products. Factor 5 can be managed by being selective with applications.
