The five weights are not a secret. FICO publishes them, every bank and credit union blog repeats them, and a reader who memorises all five is no closer to knowing which one is holding his number down this month.
Two of the five carry most of the score, and both are built entirely out of what a lender, a card issuer or a collector reported about you. When that report is wrong, the weights work exactly as published and the number is still wrong.
FICO Publishes All Five Weights, and Two of Them Carry 65%
FICO publishes the five category weights itself: payment history at 35%, amounts owed at 30%, length of credit history at 15%, new credit at 10%, and credit mix at 10% (FICO, 2026). Payment history and amounts owed come to 65% between them. FICO also says the weights describe the general population and shift with the data in an individual file, so one move lands differently on two people.
| Factor | Weight | What it reads |
|---|---|---|
| Payment history | 35% | Whether payments arrived on time, across every reporting account |
| Amounts owed | 30% | Total balances and the revolving credit utilization ratio |
| Length of credit history | 15% | Age of the oldest account and the average age of all accounts |
| New credit | 10% | Recent applications and newly opened accounts |
| Credit mix | 10% | Experience with both revolving cards and installment loans |
Treat the percentages as an order of priority. On a thin file, or one carrying a recent bankruptcy, the model leans on the categories it can actually read, so the published split is a guide to where attention pays rather than a formula anybody can run at home.
Payment History Is 35%, and FICO’s Ladder Starts at 30 Days Late
A payment is not late to a credit bureau until it is 30 days past due. FICO publishes the categories creditors report in, 30 days, 60 days, 90 days, 120 days, 150 days and charge off, and says a 90-day late is worse than a 30-day late, and that a recent late weighs more heavily than an old one (FICO, 2026). There is no rung below 30 days, which is why a payment two weeks behind shows up nowhere.
The factor reads every account type at once: cards, mortgages, auto loans, student loans. One missed payment on any of them reaches the 35% category, which is what makes payment history both the heaviest factor in the score and the easiest one to damage by accident.
A late mark can report for up to seven years. Section 605 of the Fair Credit Reporting Act, 15 U.S.C. § 1681c, sets that ceiling for a standalone late payment, measured from the delinquency itself. A collection or a charge-off is measured differently: § 1681c(c)(1) starts the seven-year clock 180 days after the delinquency that led to the collection, so that window runs about seven and a half years from the first missed payment. When a late payment is on the report in error, the fix runs through a dispute, and our guide to removing late payments sets out the steps.
Amounts Owed Is 30%, and Your Statement Date Sets the Number
Amounts owed is 30% of a FICO Score, and the part of it that moves fastest is utilization. Utilization is read off the balance your issuer reports, and that figure is fixed on the statement closing date. Paying the card down before the due date saves you interest and does nothing to the number the bureau sees; paying before the statement closes changes it. That timing decides the ratio for the 45% of credit card owners who carried a balance at least once in the prior twelve months (Federal Reserve Board, 2026), because theirs is the balance the closing date catches.
- Under 30% is the common benchmark for utilization, and under 10% is stronger still.
- Per-card and overall are both read, so one maxed card can cost you while the total still looks fine.
- Recalculated every month, which is why a paydown can show up within one billing cycle.
Utilization has no memory. A high ratio one month does not follow the file once the balance comes down, which makes it the most forgiving of the five and the fastest to move. Our guide to credit utilization covers how the per-card and overall figures interact.
Length of Credit History Is 15%, and Closing a Card Hits Two Factors
Closing an old card takes two things at once. It removes the available credit that was holding your utilization down, and in time it lowers the average account age that the 15% factor reads. The utilization hit lands on the next statement, while the age effect is slow, because a closed account in good standing can keep reporting for up to ten years.
The factor reads the age of your oldest account, the average age of all accounts, and how long specific accounts have been active. A longer record gives the model more behaviour to score, which it treats as lower risk.
A long-held card with no annual fee is usually worth keeping open even when it sits in a drawer. Put a small recurring charge on it and pay it in full, and the account stays active without costing anything.
Credit Mix Is 10%, and Chasing It With a New Account Backfires
Opening an account you do not need, in order to fill a category, costs more than the category is worth. In a randomized evaluation of 1,531 credit union members, a credit-builder loan raised the likelihood of having a credit score for participants with no existing debt but produced a small decrease of roughly 3 points for participants who already carried debt, along with more 30-day delinquencies on their other loans; the report attributes that to borrowers finding a new obligation difficult to absorb alongside the ones they already had (Consumer Financial Protection Bureau, 2020). The decrease travels with missed payments, which is the 35% factor, not the 10% one.
Credit mix is 10%, tied with new credit for the lightest of the five, and it improves on its own. A first auto loan, a mortgage, a card opened because you needed one: each adds a type the model has not seen from you yet. Our guide to credit mix breaks down what counts as revolving and what counts as installment.
New Credit Is 10%, and FICO Pools Your Rate Shopping
New credit is 10% of the score and reads recent applications and newly opened accounts, each of which can leave a hard inquiry. FICO says the effect of a single inquiry is usually small, and it is temporary: a hard inquiry sits on the report for two years, while the score counts only those from the last twelve months (FICO, 2026). Rate shopping is carved out on top of that. FICO ignores mortgage, auto and student loan inquiries for the first 30 days, then counts numerous inquiries of the same type inside a 45-day window as a single inquiry on its newest versions, against a 14-day span on older ones.
Five lender pulls inside one focused fortnight cost a borrower what a single pull costs. Spread the same five applications across four months and every one of them registers separately. Our article on whether hard inquiries hurt a credit score covers how long one stays on the file.
Opening several accounts in a short window does two things to the score at the same time: it stacks fresh inquiries, and it drags the average account age down in the 15% factor. The second effect outlasts the first by years.
Income, Savings and Age Are in No FICO Score at All
The score is built from the credit report and from nothing else. Income, savings, employment, age and marital status sit outside it entirely. A lender may weigh every one of them when it decides whether to approve you, and none of them reaches the five factors, which is why two people on very different salaries can hold the same number.
- Income, savings and bank account balances appear in no FICO score.
- Age, marital status and similar personal details are not scoring inputs.
- Checking your own credit report is a soft inquiry and never lowers a score.
A raise at work moves nothing. What moves the number is a line on the report changing, which is a narrower target than most advice implies and a more useful one.
Does Carrying a Balance Help a Credit Score? No
What the model reads is on-time payment and low utilization, and paying a statement in full satisfies both at once. Rolling the balance into next month adds interest and nothing the score can see. The average annual percentage rate reached 25.2% on general purpose cards in 2024 (Consumer Financial Protection Bureau, 2025), so this particular myth carries a price.
The confusion has a real root. An active account reports more for the model to read than a dormant one does, so activity genuinely matters. A revolving balance left unpaid is simply not what creates that signal: a card used every month and cleared every month reports exactly the same active, on-time pattern, without the interest.
Defaults and Collections Are What Actually Sink a File
A low score is the record of something that already went wrong, and two mass events have been writing that record lately. Federal student loan defaults returned at scale: about 1.0 million were reported to the credit bureaus in the fourth quarter of 2025 and another 2.6 million in the first quarter of 2026, with newly defaulted borrowers seeing an average credit score drop of 91 points, from 567 to 476, between the third quarter of 2024 and the fourth quarter of 2025 (Federal Reserve Bank of New York, 2026).
Collections are the second. About 77 million Americans, 35% of adults with a credit file, carry debt in collections, owing an average of $5,178 and a median of $1,349 (Urban Institute, 2025).
Both of those land in payment history and amounts owed, the two factors carrying 65% of the score. Knowing that payment history is weighted at 35% tells you nothing about how it got damaged. Knowing that defaults and collections are what put the damage there tells you where to look on the report first.
The FTC Found Errors in the Data Those Two Factors Read
The five factors read data somebody else reported, and that data is not always right. One in five consumers had an error on at least one of their three credit reports, and for 5% of consumers the error was serious enough that it could raise the price they pay for credit or insurance (Federal Trade Commission, 2013).
An error gets no line of its own in the five factors. It arrives inside payment history as a late that never happened, or inside amounts owed as a balance that was already paid, and the model weighs it exactly as it weighs a real one. So the arithmetic runs correctly and the number it produces is still wrong.
Section 611 of the Fair Credit Reporting Act, 15 U.S.C. § 1681i, gives Equifax, Experian and TransUnion about 30 days to reinvestigate a dispute and requires them to delete or correct anything they cannot verify. Our guide to finding and disputing credit report errors covers what to send and where.
Read the Reason Codes Before You Work Any Factor
Every score arrives with reason codes, the short phrases printed beside the number by a lender or a free score tool: high utilization, a recent missed payment, too few accounts. They are ranked, and the top one names the factor costing you the most today. Reading them beats guessing which of the five to work on.
Pair the codes with a full read of all three credit reports and you have both halves. The codes say which factor, and the reports say which account. Our guide to improving a credit score works through the order below in detail.
- Bring any past-due account current, so no new late mark gets reported.
- Pay revolving balances down before the statement closing date, not the due date.
- Leave new applications alone while the rest of this is in progress.
- Keep older accounts open, for the account age and the available credit both.
- Dispute anything on the report that is inaccurate, incomplete, unverifiable, or too old to be reported.
The order is deliberate. The first two move within a billing cycle or two, the third and fourth stop new damage, and the fifth is the only one that reaches an item the other four cannot touch.
Skip the paperwork. Start your dispute.
CreditRefresh drafts your FCRA dispute letter and tracks the 30-day investigation window. You review, approve, and send. You stay in control.
Get StartedEach Bureau Holds Its Own File, So One Model Returns Three Scores
Equifax, Experian and TransUnion each keep their own file, and a lender is free to report to one, two or all three. Run the same model against three different files and three different numbers come back, none of them wrong. It is also why a dispute is filed bureau by bureau: correcting an item at one leaves it standing at the other two.
The 35, 30, 15, 10, 10 split describes the general purpose FICO model. VantageScore reads similar inputs on its own weights and can score a thinner file, and the industry versions some auto and card lenders order weigh certain behaviours differently, which is how one consumer holds a dozen valid scores at the same moment. Our comparison of FICO and VantageScore sets out where the two part company.
The Consumer Financial Protection Bureau keeps a consumer guide to the scores in circulation at consumerfinance.gov, and the Federal Trade Commission covers protecting a score at consumer.ftc.gov. Neither of them sells you a score, which is the reason to start there.
The Weights Are Published, and the Data Under Them Is Unchecked
The five weights are the easiest thing about a credit score to look up and the least useful thing to know on their own. Payment history and amounts owed carry 65% between them, and every input to both is a line a furnisher chose to send. Nobody at the bureau confirms those lines are true before the model scores them.
So the practical order is backwards from the way this topic is usually taught. Read all three reports first, find out what the five factors are actually reading, and only then decide which factor is worth your month.
Choosing a tool to check the entries behind your score
Knowing the five factors helps you decide what to work on. You still need to see whether the report has the right balances and payment history. In our September 18, 2026 data, paying CreditRefresh members averaged 38.3% revolving utilization; the median was 22%. The tools below differ in how they help you read the file, watch it change and challenge an error.
| Tool | What you pay | What that buys | Bureaus | Trustpilot |
|---|---|---|---|---|
| CreditRefresh | $49.99/mo, no setup fee, cancel anytime. Mail letters yourself free, or pay RushMail per letter | Checks payment and balance entries across all three reports and drafts a letter for each item you choose to challenge. Monitoring lets you follow changes. You read and sign each letter | All three | 4.3 (9 reviews) |
| Dispute Beast | From $49.99/mo for required monitoring. Mail letters yourself free, or pay Sprint Mail per letter | The dispute tool reads the same data free; the monitoring that finds the errors is not free. Mail the letters yourself at no charge, or pay Sprint Mail per letter | All three | 4.2 (2,067 reviews) |
| DisputeBee | $49/mo personal, $129/mo business | You find the wrong line yourself, draft the letter, and log every bureau’s reply across all three reports | All three | 3.2 (68 reviews) |
| The Credit People | $99/mo standard, $119/mo premium, or $599 for 6 months | Someone else finds and challenges what’s wrong in your file, but you never see which line they’re disputing | All three | 1.7 (17 reviews) |
| Lexington Law | $139.95/mo, invoiced at the end of each service period | A law firm works the file for you, with no self-serve view into what’s actually being challenged | All three | 3.2 (624 reviews) |
| Credit Karma | Free, paid for by lender referrals | Flags that a number moved, but reaches only TransUnion and drafts nothing to fix what moved it | TransUnion | 1.1 (912 reviews) |
Every price here is that company’s own published rate, read off that company’s own site on September 15, 2026. Trustpilot scores and review counts as published on September 24, 2026.
A score tells you where the number stands. The report gives you the entries to check against your own records. New System, a 1 star Trustpilot review of Credit Karma, June 21, 2026: “Paid off $5000 to get a 70 point drop… they dropped me 70 points with the recommendation to sign up for more cards.” When an entry is wrong, the useful next step is a dispute that names it.
Work on the report behind the score with CreditRefresh
A score drop gives you a number to worry about. CreditRefresh gives you the three reports to check and a letter for each item you choose to dispute. If a payment is marked late when you paid on time, you have a clear place to start and a letter you can review before sending.
The next report can show what changed. Our September 18, 2026 member data found that 47.9% of disputed items with a recorded outcome no longer appeared on a later report from the same bureau. Outcomes were recorded for 2.3% of items in mailed rounds, across all dispute types. With monitoring, you can keep checking the balances and payment entries that feed your score.
CreditRefresh is included with Refresh Monitoring for $49.99 a month, with no setup fee, no charge per dispute and no contract. You can cancel any time. You decide what to challenge and sign each letter before it goes out.
It is backed by our 100% money-back guarantee: members who work the full program and see no bureau score rise above where they started can claim back every Refresh Monitoring payment. It is a refund promise, never a score promise.
Frequently asked questions
What are the five C’s of credit, and are they the five score factors?
They are two different things. The five C’s are what a loan officer weighs on one application, including things a score never sees, such as your income and any collateral behind the loan. The five factors here are what the scoring model reads off your credit report, and the model sees no income at all.
Is a 900 credit score possible?
Not on a FICO Score, which runs 300 to 850. Some specialist and industry scores use other ranges, so a number above 850 on a screen is a different scale rather than a better result.
Why did my score drop after I paid off a loan?
Closing out an installment loan ends an active account, which can shorten the average age the 15% factor reads and remove the only installment entry in the mix. Our article on a score drop after paying off a loan goes through what changed and what to expect next.
Does paying a collection in full take it off my report?
No. Paying changes the status to paid, and the item may still be reported. Section 605(c)(1) starts the seven-year clock 180 days after the delinquency that led to the collection, so the window runs about seven and a half years from the first missed payment, not seven. A paid collection is treated more kindly by the newest scoring models than by the older versions some lenders still order.
Does my bank account or debit card affect my credit score?
Neither one is furnished to Equifax, Experian or TransUnion, so a checking balance and a debit card do not reach the five factors. An unpaid overdraft can reach them later, once the bank charges the balance off and sells it to a collector who does report.
Do I need an installment loan as well as a card for a good score?
No. Credit mix is 10% of the score, tied with new credit for the lightest of the five. A file carrying nothing but well-handled revolving cards can score well; taking on a loan you do not need to fill the category costs more than the category is worth.
How long does a change in one factor take to show up?
Utilization can move within one or two billing cycles, because the figure is recalculated every month. Age and payment history move over years, and the weight of a late payment or a collection fades gradually as the item gets older, well before it falls off. There is no fixed timeline, and what happens depends on which items are on the file and how recent they are, so two people taking the same steps may see different results.
