The complete DIY credit picture

Credit can feel like a hundred separate problems. It's really a handful of pieces that fit together. Here's every major piece, one short paragraph each, so you can see the whole map before you start.

Reports. Your three credit reports are the record everything else is built on. Get them free every week at AnnualCreditReport.com and review them line by line.

Scores. A score is a number calculated from your report. Payment history and amounts owed matter most. There are many scoring versions, so your numbers will vary.

Disputes. You have the legal right to dispute information you believe is inaccurate, incomplete or unverifiable. The bureau generally has to investigate. Accurate negative information can usually stay for its full reporting period.

Utilization. How much of your card limits you're using. Lower is generally better, and it's based on the balances on your latest reports.

Authorized users. When someone adds you to their credit card, that card's history may show up on your report. It can help if they use it well, and hurt if they don't. Not every lender or scoring model weighs it the same.

Tradelines. Some companies sell spots as an authorized user on a stranger's card. It's expensive, the results aren't guaranteed, and some lenders discount it. Never use a "CPN" (credit privacy number) in place of your Social Security number. Using one to get credit can be a federal crime.

Rent reporting. Services can report your on-time rent payments to one or more bureaus, sometimes for a fee. Some newer scoring models count it, but many lenders' scores may not.

Building new credit. Secured credit cards and credit-builder loans are common ways to add positive history when you have little or none. Pay on time and keep balances low.

• Authorized user: someone allowed to use another person's credit card, without being responsible for the debt.
• Secured card: a credit card backed by a deposit you put down.
• Credit-builder loan: a small loan where your payments are saved for you and reported as you pay.
• CPN: a "credit privacy number" sold as a way to start a new credit file. Avoid it.

Bri's plan, in order: pull all three reports, highlight two items that look wrong and gather proof, pay her highest-utilization card down before its closing date, set autopay on everything, and open a secured card because her file is thin. Each step is small. Together, they cover reports, accuracy, utilization, payment history and building credit. (Made-up example.)

• Order matters. Start with accurate reports, then work on the factors you control.
• Be skeptical of anyone who promises a specific score, a deletion or a timeline.
• Shortcuts like CPNs or false identity theft claims can create legal trouble, not better credit.
