How to Build Credit From Scratch at 18 to 25

Open one account that reports to all three credit bureaus, keep its balance small, and pay it on time every month for six months. Six months of history is the minimum FICO needs to give you a score at all. The hard part of building credit from scratch is choosing the right first account and not wrecking it in year one.

Quick version

• Debit cards, prepaid cards and cash do not build credit. Only reported accounts count.
• Pick one starter: a secured card, a credit-builder loan, authorized-user status, or a student card.
• Before you sign, ask whether it reports to Equifax, Experian and TransUnion.
• Turn on autopay for at least the minimum, and keep the balance well under 30% of the limit.
• Expect a first FICO score after about six months of history.

How credit actually gets built

A credit score is a summary of your credit report, and your report only contains accounts that lenders send to the bureaus. That’s why someone with a paid-off phone and five years of on-time rent can still have no score: none of that was reported.

FICO’s own breakdown shows what moves the number. Payment history is 35% of the score, amounts owed is 30%, length of history 15%, new credit 10% and credit mix 10%. For a beginner, the first two matter most. Pay on time, and don’t run the card up.

The CFPB’s research on how people first get a credit record is useful here. In a sample of more than a million people, almost 80% of first credit records appeared before age 25. Credit cards started more records than any other product, and about 1 in 4 people got their first history from an account someone else was also responsible for (a co-signed loan or authorized-user status).

Pick your starter account

Read across the row that matches your situation.

If you’re unsure, a secured card from your own bank or credit union is the simplest single move. If you can’t spare a deposit, a credit-builder loan or authorized-user status gets you started without one.

How to build credit from scratch in six months

1. Pull your reports first. Go to AnnualCreditReport.com. The three bureaus have permanently extended free weekly reports there, and checking your own report does not affect your score. You’re looking for two problems: accounts that aren’t yours, or a file that doesn’t exist yet.
2. Choose one starter from the table. One is enough. Opening several at once adds hard inquiries, and Ramit Sethi’s site warns that a burst of applications can look like financial desperation to lenders.
3. Ask the reporting question. Before you apply, ask: “Do you report to Equifax, Experian and TransUnion?” A product that skips a bureau leaves you with a blank file at that bureau.
4. Set autopay the day the account opens. At minimum, autopay the minimum due. Better, autopay the full statement balance. One missed payment can sink a new file.
5. Use it lightly. Put one small recurring bill on the card, like a phone bill or a streaming plan, and nothing else. Keep the balance well below 30% of the limit. On a $500 limit, that’s under $150, and lower is better.
6. Check your reports again at month two or three. The new account should be listed at each bureau it reports to. If it isn’t, call the issuer.
7. At month six, check for a score. FICO needs at least one account open six months or more and one account reported in the last six months. Many banks and card apps show a free score.
8. After six to twelve months of clean payments, ask about upgrading. Many secured cards convert to unsecured cards and refund the deposit. Keep that first account open even after you get a better card, because its age helps your history.

What does not count

The CFPB lists debit cards, cash, prepaid cards and payday loans as products that don’t build credit, because they aren’t reported to the nationwide bureaus (payday loans often aren’t reported even when you pay on time). “Buy here, pay here” car lots may report only your late payments. If someone sells you a product as a credit builder, ask whether your on-time payments reach the bureaus. If they don’t, it won’t help.

Once your first card is open, keep it boring. Don’t let free trials pile up on it; our guide on how to cancel subscriptions shows how to find and kill them. If you’re starting a first job at the same time, how to negotiate salary and how to fill out a W-4 are the other two money tasks worth doing this month.

The under-21 rule

Under the Truth in Lending Act, a card issuer generally can’t give you a credit card before 21 unless you can show you can pay on your own, or someone over 21 co-signs and takes on responsibility for the debt. A part-time job usually counts as independent income. A parent’s income that you merely have access to usually doesn’t. If that rules out a regular card, the secured card, credit-builder loan and authorized-user routes still work.

What the pros say

• Rod Griffin, who runs consumer education at Experian, suggests students start as an authorized user, which he calls very safe because the user isn’t responsible for the debt, or with a secured card from a bank or credit union. In a 2025 WDBJ interview he recommends thinking about credit at 18 to 20 and starting with a low-limit card.
• Ramit Sethi, author of I Will Teach You to Be Rich, lays out the same three on-ramps (secured card, a card from the bank you already use, authorized user) and says to check that the issuer reports authorized users before you bother. He also suggests asking for a credit limit increase about every six months, as long as your spending doesn’t climb with it, to keep utilization low.
• Matt Schulz, then an industry analyst at CreditCards.com, told Consumer Reports a secured card is a good way to build credit while keeping risk low. For co-signed cards, he advised the co-signer to keep full access to the account, since they’re on the hook for payments.
