Understand What Impacts Your Credit Score
Credit scores aren't random. They're built from patterns lenders see in your report — not guesswork. This guide walks through the five major FICO score factors and how each one generally shapes the score you see today.
Quick answer: What are the 5 credit score factors?
FICO scores weight five categories differently — payment history and utilization drive most of the movement.
- Payment history:~35% — on-time vs. late payments.
- Utilization:~30% — reported revolving balances vs. limits.
- Credit age:~15% — average age of your accounts.
- Credit mix:~10% — revolving plus installment.
- New credit:~10% — recent inquiries and new accounts.
1. Payment history
Payment history is widely considered the single largest factor in most FICO scoring models — generally around 35% of the score. It reflects whether revolving accounts, installment loans, and other tradelines have been paid as agreed.
Lenders look at how recent a late payment is, how severe it was (30, 60, 90+ days), and how often it has happened. Older, isolated late payments typically influence a score less than recent or repeated ones.
2. Credit utilization
Utilization is the ratio between your reported revolving balances and your total revolving credit limits. It's generally the second-largest factor in most FICO models (~30%).
Because utilization is based on what's reported — not what you owe in real time — the statement balance a card issuer sends to the bureaus is what most scoring models actually see.

3. Length of credit history (credit age)
This factor considers the age of your oldest account, the age of your newest account, and the average age across all accounts. Generally about 15% of the score.
Closing an old account doesn't necessarily wipe its history right away, but it can reduce your average age over time and may affect future score potential.
4. Credit mix
FICO models reward consumers who have demonstrated they can responsibly manage multiple account types — for example, revolving credit (credit cards) alongside installment credit (auto loan, mortgage, personal loan). Generally about 10%.
Mix is a small factor and isn't a reason to open accounts you don't need.

5. New credit and inquiries
Applying for new credit generates a hard inquiry, which can have a small, temporary effect on your score. Opening several accounts in a short period may signal additional risk to lenders. Generally about 10%.
Most scoring models distinguish "rate shopping" (multiple inquiries for the same kind of loan within a short window) from broad credit-seeking behavior.
Why strategy matters
Knowing the five factors is one thing — knowing what order to address them in is another. A high-utilization profile, a thin file, and a profile recovering from a collection account each respond to different strategies.
That's what The 700 Score System™ is built to teach: how to read your own profile, identify which factors are working against you, and make structured educational decisions instead of reactive ones.
