How long does it take to build credit?

The realistic timeline

The first milestone is the concrete one. FICO's general scoring models require at least one account that has been open for six months or more, with activity reported to that bureau within the last six months. Until then you are not "unscoreable because your credit is bad" — you have no file to score.

Everything after that is a slope rather than a set of gates.

Why the early months are slow

Two of the five scoring factors are functions of time. Length of credit history is 15% of a FICO score, and it starts at the floor and can only rise. New credit is another 10%, and a brand-new account counts against you there for a while.

So a new file starts with about a quarter of the model working against it for reasons that have nothing to do with your behavior. That is not something to fix; it is something to wait out.

Meanwhile the two factors you can control — payment history and amounts owed — are worth roughly 65%. Which is why the advice for a new file is so short: pay on time, keep the balance low, and do not apply for anything else.

What to do in month one

A secured card is usually the most direct route. You put down a deposit, typically equal to your credit limit, and the account is reported to the bureaus like any other card. The deposit is what makes the issuer willing to approve someone with no history. Check that the issuer reports to all three bureaus — the card is useless for this purpose if it does not.

A credit-builder loan works the other way round: the money you borrow is held in an account and released when you have finished repaying. You are effectively paying to have an installment payment history reported.

Becoming an authorized user on someone else's well-managed card can add their account history to your file, depending on the issuer and the scoring model. It is the fastest of the three, and it depends entirely on the primary cardholder's behavior — if they miss payments, that lands on your report too.

A student card may be available if you are enrolled, with more forgiving approval criteria.

Rebuilding takes longer than building

Starting from zero, you have nothing working against you but time. Starting from damage, you have both.

• A 30-day late payment generally stays on your report for seven years.
• A collection account generally stays for seven years from the original delinquency.
• A Chapter 7 bankruptcy generally stays for ten years.

Their weight decays. A late payment from year six barely registers next to one from last month. But the item remains visible, and a lender reading the report — as opposed to just the score — can see it.

The one thing that speeds this up is new positive history accumulating alongside it. Six months of perfect payments on a secured card does more for a damaged file than waiting does.

What to do while you wait

1. Automate the minimum payment. Not because minimums are a good idea to carry, but because an automated payment cannot be forgotten. Pay the rest manually.
2. Keep reported balances low. Use the credit utilization calculator to see where you stand and what to repay.
3. Do not close your first account. It will one day be your oldest, and that is worth more each year.
4. Stop applying. Every application resets part of the "new credit" clock.
5. Check your report. An error you have been carrying for two years is the one thing on this list that can improve overnight.
