How long does it take to build credit?
You need at least six months of account history before a FICO Score can be calculated at all, per FICO's own minimum scoring criteria. From there, most people who pay on time and keep balances low reach "good" credit (670+) within roughly a year, and "excellent" (760+ or 800+) takes several years more, because age of credit history is 15% of your FICO Score, and age is the one factor that only comes from time. Negative marks fade too, but slowly: late payments and collections drop off after 7 years, Chapter 7 bankruptcy after 10.
What's the minimum time to get a FICO Score at all?
Six months. FICO's published minimum scoring criteria require a credit file to have at least one account open for six months or more, and at least one account that has reported activity to a credit bureau within the past six months, before a FICO Score can be generated. Miss either condition and there is no score yet, not a low one, no number at all.
If you are approved for a new account today and it is used and reported normally, you should have your first FICO Score in about six months. VantageScore can sometimes generate a score sooner, but FICO Scores are what most U.S. lenders actually pull, so six months is the realistic floor.
How long does it take to reach a "good" credit score (670+)?
There is no official published timeline. Neither FICO nor the credit bureaus commit to a fixed number of months, because the answer depends heavily on your starting point and how you use credit in the meantime. What credit-reporting company Experian tells consumers directly: reaching good credit "can take a year or more, depending on your habits and starting point," and building a solid credit history "often takes years, not months." That lines up with the mechanics: payment history (35% of your FICO Score) and amounts owed (30%) respond within a few billing cycles, but you need enough of a track record, several months of on-time payments reported consistently, before those categories score you well.
In practice, someone who opens one account, uses it lightly, and pays it off in full every month tends to clear 670 somewhere in the second half of their first year of credit history, assuming no missed payments and no other accounts dragging on the file. That is a general pattern, not a guarantee.
How long does it take to reach "excellent" credit (760+ or 800+)?
Longer, and here the age factor becomes unavoidable. Length of credit history is 15% of a FICO Score, and it is calculated from the age of your oldest account and the average age of all your accounts. You cannot shortcut this the way you can shortcut utilization by paying down a balance. Experian's own guidance is blunt: there is no set timeline to reach any specific score, and taking a score "from middling to excellent will take months, if not years, of steady, prudent credit management."
Realistically, a thin, brand-new file cannot hit 760+ in its first year even with flawless payments, simply because the average account age is too young. Excellent credit is less a target you sprint toward and more a byproduct of several years of clean history, low balances, and no new-credit churn.
How long do late payments, bankruptcy, and other negatives stay on your report?
This is set by federal law, not by FICO, and it does not depend on how quickly you improve your habits afterward. The Fair Credit Reporting Act (FCRA) fixes how long credit reporting companies can report most negative information, and the Consumer Financial Protection Bureau (CFPB) publishes the same limits for consumers.
| Item | Time on report | Counted from |
|---|---|---|
| Late payment | 7 years | The date of the missed payment |
| Collection account / charge-off | 7 years | The date the account was first placed for collection or charged off |
| Chapter 7 bankruptcy | 10 years | The filing date |
| Chapter 13 bankruptcy | 10 years | The filing date |
| Civil judgment | 7 years, or until the statute of limitations expires, whichever is longer | The judgment date |
| Hard inquiry | About 2 years | The date of the credit application |
| Positive, on-time payment history | Indefinitely, as long as you keep paying on time | Not time-limited |
Sources: 15 U.S.C. § 1681c (Fair Credit Reporting Act); CFPB, "How long does information stay on my credit report?"; myFICO, "The Timing of Hard Credit Inquiries."
Two nuances worth knowing. First, a hard inquiry (a lender pulling your report because you applied for credit) sits on your report for about two years, but myFICO notes that FICO Scores only count inquiries from the last 12 months, so its scoring impact fades well before it disappears from the report entirely. Second, none of this is optional or negotiable through a "credit repair" service: the FCRA time limits apply regardless of who you pay, and a company cannot legally remove accurate negative information before its time is up.
Why does age of credit history matter so much?
Because it is one of the five official FICO Score factors, worth 15% of the total, and it is the only one you cannot accelerate. myFICO's own breakdown of "what's in my FICO Scores" lists payment history at 35%, amounts owed at 30%, length of credit history at 15%, new credit at 10%, and credit mix at 10%. The first two respond to behavior you control this month. Length of history responds to nothing but the calendar: it looks at how long your oldest account has been open and the average age across all your accounts.
This is also why opening a pile of new accounts to "build credit fast" can backfire. Each new account starts at age zero and pulls your average account age down, working against the 15% you are trying to grow. Patience is not just advice here, it is built into how the score is calculated.
What's the fastest legitimate way to build credit?
Rank the levers by how quickly they can move a score, and the honest order looks like this:
- Pay on time, every time. Payment history is 35% of your score, the single largest factor, and a track record of on-time payments starts compounding from your very first bill.
- Keep utilization low. Amounts owed is 30% of your score, and it recalculates every time your balance is reported, usually monthly. For the mechanics and the 30%/10% guidelines, see what is credit utilization.
- Get a starter product that reports to the bureaus. The CFPB points to secured credit cards, credit-builder loans, and retail store cards as accessible ways to start a credit file, provided the issuer actually reports your activity to the credit reporting companies.
- Consider becoming an authorized user. myFICO describes this as a way to establish a score without applying for credit of your own: if a friend or family member adds you to a card in good standing and the issuer reports the account under your name too, that history can help your file. myFICO also warns it cuts both ways, an account with late payments or a high balance can hurt you the same way a good one helps.
- Then wait. None of the above substitutes for time. Length of history only grows one way.

A worked timeline: zero credit to "good"
Here is a realistic, if generalized, walk from no credit file to crossing 670, assuming on-time payments throughout and no other negative marks:
| Month | Milestone |
|---|---|
| Month 0 | Open a secured card or become an authorized user; first activity begins reporting to the bureaus |
| Months 1 to 5 | Payment history accumulates; no FICO Score exists yet |
| Month 6 | Minimum scoring criteria met (one account open 6+ months, reporting within the last 6 months); a first FICO Score becomes available |
| Months 6 to 12 | Score typically climbs out of the "fair" range as on-time payments and low utilization accumulate |
| Around 12 months | Many consumers with clean payment histories cross into "good" (670+) |
| Several years | "Excellent" (760+/800+) becomes realistic once average account age, not just behavior, has caught up |
Source: CobaltProsper illustration based on FICO's minimum scoring criteria and FICO Score factor weights (myFICO), and Experian's stated guidance that there is no fixed timeline and reaching good credit typically takes a year or more. Individual results vary with starting point, account mix, and payment history.
Notice what does not appear on this table: a shortcut. Every faster-sounding trick, disputing accurate items, opening several cards at once, buying an "authorized user tradeline," either does nothing or works against the length-of-history factor you are trying to build.
The flat truth on how long credit takes
Credit-building has exactly one speed limit, and it is time. Six months to get a score, roughly a year to get a good one if you do everything right, and several years to get an excellent one, because a third of what makes a score excellent is simply how long your accounts have existed. Negative marks run on the same clock in reverse: seven years for late payments and collections, ten for a Chapter 7 or Chapter 13 bankruptcy, whether or not you have since become a model borrower.
The only genuine lever is behavior sustained over that time: pay every bill on time, keep balances low, open new accounts sparingly, and let the calendar do the rest. For what a given score actually gets you once you arrive, see what is a good credit score.
