The 5 FICO Factors: Your Score at a Glance
Your credit score has 5 ingredients. Let's open the recipe.
In this lesson you will learn to
- Name the five FICO factors and the weight of each
- Explain why payment history and utilization matter most
- Calculate your utilization on one credit card
- Decide which factor to work on first
Your FICO score comes from five categories of information. Each one carries a weight, a percentage that sets how much it moves your score. Once you know the weights, you know where to put your effort first.
Payment History
Amounts Owed (Utilization)
Length of Credit History
Credit Mix
New Credit & Inquiries
Why These Specific Percentages?
FICO spent decades studying millions of credit files to find which factors best predicted future payment behavior. The percentages are not arbitrary. They reflect how strongly each factor tracks with loan default in real data. Payment history carries the most weight for a simple reason: nothing predicts future behavior better than past behavior. The other percentages reflect real statistical links between each factor and the odds of default.
Try it: hover, tap, or use the arrow keys on a factor to see its weight and the one habit that moves it.
Payment history (35% of your score)
Do you pay on time? The model looks at how late (30, 60, or 90+ days), how recent, and how many accounts it touched.
The habit that moves it: Pay at least the minimum on time, every month. Autopay makes that automatic.
Notice that payment history and utilization together make up 65% of the wheel. That is where effort pays off first.

Which two FICO factors carry the most weight, and how much do they add up to?
Factor 1: Payment History (35%)
This is the big one. Have you paid your accounts on time? Every on-time payment builds your record as a reliable borrower. Every late payment is a red flag. The model looks at how late (30, 60, or 90+ days), how recent, and how many accounts it touched. One 30-day late payment from 4 years ago hurts less than a 90-day late from 6 months ago.
Factor 2: Amounts Owed, or Utilization (30%)
This factor looks at how much of your available credit you are using, mostly on revolving accounts like credit cards. If your card has a $10,000 limit and you carry a $3,000 balance, your utilization is 30%. Lower is better. Lenders read high utilization as a sign of financial stress. This is one of the fastest factors to improve. It changes as soon as you pay balances down and the card issuer reports the new balance.

Factor 3: Length of Credit History (15%)
How long have your accounts been open? This includes the age of your oldest account, your newest account, and the average age of all of them. A longer history gives lenders more data to judge. This is the one factor you cannot rush. Time is the only fix. But you can protect it by keeping old accounts open.
Factor 4: Credit Mix (10%)
Have you handled different types of credit? Revolving credit (credit cards, lines of credit) and installment credit (car loans, mortgages, student loans) behave differently. Having both shows lenders you can manage more than one kind of debt. This factor matters less than the others, so do not open new accounts just to add variety. The risk usually outweighs the gain.
Factor 5: New Credit & Inquiries (10%)
When you apply for new credit, the lender pulls your credit report. That is a hard inquiry. Each one has a small, short-lived negative effect. This factor also counts the average age of your newest accounts. People who apply for a lot of new credit in a short time can look desperate for money, and that worries lenders.
Why Two Factors Are Each Just 10%
Credit mix and new credit each carry 10% because FICO's data showed they have real but minor links to default risk. They are worth understanding and managing. But obsessing over them while ignoring the top two factors (payment history and utilization, 65% of your score together) is a mistake many people make.
Real-World Examples
Real-World Example
Two people, same income, very different scores
The Situation
Rachel and Kevin both earn $70,000 a year. Rachel has a 780 score. Kevin has a 620.
What Happened
Rachel: 3 credit cards, all under 15% utilization, no missed payments, oldest account 8 years old. Kevin: 2 cards, one at 85% utilization, one 60-day late payment last year, oldest account 2 years old.
Key Takeaway
Income is not part of your credit score at all. The score is about how you manage debt, not how much you make. You can earn $200,000 a year and have terrible credit.
Rachel and Kevin, side by side
| Detail | Rachel | Kevin |
|---|---|---|
| Income | $70,000 | $70,000 |
| Credit cards | 3 | 2 |
| Utilization | All under 15% | One card at 85% |
| Missed payments | None | One 60-day late last year |
| Oldest account | 8 years | 2 years |
| Score | 780 | 620 |

Where to Focus First
If you want to improve your score quickly, start with utilization (Factor 2). Paying down card balances can raise your score within 30 days, once the card issuer reports the lower balances. Then protect your payment history (Factor 1) by paying on time from here forward. Factors 3, 4, and 5 tend to take care of themselves when you manage the first two well.
Dee Picks One Factor
Dee had three things on her report that bothered her: a 60-day late from last year, two cards near their limits, and a credit history only three years old. She wanted to fix all of it at once and did not know where to start.
She wrote the five factors on a sticky note with their weights. The late payment was already on the record, and only time would fade it. The short history would only grow with time too. But amounts owed count for 30% of the score, and she could change her balances this month.
So she stopped worrying about the parts she could not move. She put her tax refund toward the two cards and set both on autopay for the minimum. When the issuers reported the lower balances, her score moved up. Not all the way, but in the right direction, and she had done it on purpose.
What to remember
- Five factors: payment history 35%, utilization 30%, length of history 15%, credit mix 10%, new credit 10%.
- Payment history and utilization together are 65% of your score. Start there.
- Utilization is the fastest factor to move. Pay balances down and it can change within 30 days.
- Length of history only grows with time. Keep old accounts open.
- Income is not in the score. How you manage debt is what counts.
Do this today
Pick one credit card. Find its current balance and its credit limit on the statement or in the app. Divide the balance by the limit. That number is your utilization on that card. Write it down; you'll use it again in the utilization module. No card yet? Write down 0% and note that Module 9 covers how to open your first account.
Nice work
You can now name all five FICO factors, and you know the two that carry most of the weight. That alone puts you ahead of most borrowers. Next: the three credit bureaus, and why your score can differ from one to the next.
