How to Build Good Credit

I built my credit from essentially zero starting at 22. No credit history, no one to co-sign, a checking account with $300 in it. The first secured card I got required a $200 deposit and gave me a $200 limit. Within three years I had a credit score above 750. It’s not magic — it’s just knowing which actions actually move the needle and being consistent about them.

Here’s what actually works.

Start with a Secured Credit Card

A secured card is the most accessible starting point if you have no credit or damaged credit. You put down a cash deposit — typically $200-500 — that becomes your credit limit. The card works like a regular credit card in every way that matters for credit building: it reports monthly to all three bureaus, it establishes a payment history, and it demonstrates responsible revolving credit use.

Use it for small regular purchases — gas, groceries, a subscription — and pay the full balance every month. Don’t use it to spend money you don’t have. After 12-18 months of on-time payments, most issuers will upgrade you to an unsecured card and return your deposit.

Discover it Secured and Capital One Platinum Secured are two of the better options because they report to all three bureaus and have clear paths to graduation to an unsecured product.

Become an Authorized User

If a parent, spouse, or trusted person with good credit is willing to add you as an authorized user on their card, their positive payment history on that account can help establish yours. You don’t even need to use the card or have it in your possession — just being listed as an authorized user can cause the account to appear on your credit report.

The key word is “trusted.” The primary cardholder’s credit score is unaffected by adding you, but their credit could be harmed if you’re given the physical card and run up a balance they’re responsible for. This works best within families with clear communication.

Apply for a Credit Builder Loan

Credit builder loans are specifically designed for people with no credit or poor credit. The structure is unusual: the lender holds the loan amount in a locked savings account while you make monthly payments. When you’ve paid off the loan, you receive the accumulated funds. The monthly payments get reported to the bureaus, building your payment history.

Self (formerly Self Lender) is the most visible national option. Many credit unions offer similar products. These loans won’t enrich you — the interest you pay is essentially the cost of the credit building service — but for someone who can’t qualify for any other product, they work.

Payment History Is Non-Negotiable

Payment history is the single largest component of your credit score — roughly 35% of your FICO score. One 30-day late payment can drop a good score by 50-100 points and stays on your report for seven years. Set up autopay for at least the minimum payment on every account. I use autopay for the full balance to avoid ever carrying interest; the minimum autopay is a floor, not a target.

Keep Credit Utilization Low

Credit utilization — the percentage of available credit you’re using — is roughly 30% of your score. Using $900 of a $1,000 limit looks very different to a scoring model than using $900 of a $10,000 limit. Two ways to improve utilization: pay down balances, or increase limits (either by asking for a limit increase on existing cards or opening new accounts).

Most guidance says keep utilization below 30%. For the best scores, below 10% is better. On a $1,000 limit, that means keeping your reported balance under $100. If you use the card for daily purchases and pay in full monthly, make sure your balance is low on the day the issuer reports to the bureaus — which is usually around your statement closing date, not your payment due date.

Monitor Your Credit Report

You’re entitled to a free credit report from each bureau every 12 months at annualcreditreport.com. Pull all three annually and look for errors — wrong accounts, incorrect late payments, addresses or employers you don’t recognize, accounts that should have fallen off after seven years but haven’t. Errors are more common than most people realize.

Disputing errors is done by writing to the bureau (Equifax, Experian, TransUnion) with documentation. Bureaus have 30 days to investigate and must correct or remove information that can’t be verified. This process has significantly improved scores for people I know who caught inaccuracies.

Limit Hard Inquiries

Each time you apply for credit, the lender does a hard pull on your report, which causes a small temporary dip — usually 5-10 points. The impact fades within a year and falls off the report after two years. Multiple hard inquiries in a short period send a signal that you’re aggressively seeking credit, which scoring models treat as mildly negative.

Mortgage and auto loan inquiries get special treatment — multiple inquiries within a 14-45 day window are often counted as a single inquiry, because rate shopping is recognized as a smart consumer behavior. But for credit cards, each application is a separate inquiry.

Maintain a Mix of Credit Types

Credit mix — having a combination of revolving accounts (credit cards) and installment loans (auto, mortgage, student loans) — accounts for about 10% of your FICO score. Having only credit cards or only installment loans is mildly suboptimal. You don’t need to take out loans you don’t need to optimize this; it’s just something to be aware of as your credit profile develops.

Keep Older Accounts Open

The average age of your accounts factors into your score — the longer your credit history, the better. Closing an old account removes it from your average age calculation over time. If an older card has no annual fee and you’re not using it, the smart move is usually to make a small purchase on it every few months to keep it active, then pay it off. Banks occasionally close inactive accounts, which you don’t want.

Building credit takes time. There’s no way to shortcut years of payment history. But the compound effect of 2-3 years of responsible credit use is surprisingly powerful — scores that started at 580 can reach 720+ within three years with consistent habits. Start with the basics, be patient, and don’t make it more complicated than it needs to be.
