Credit, from zero

Your credit score is a number, usually 300 to 850. It tells a lender one thing: how well you pay back money you borrow. It is your track record, turned into a single number.

Here is why it matters so much. That number sets the price of almost everything you borrow. A high score means a lender charges you less interest. A low score means they charge you more, or say no. On a car loan, the gap between a good score and a bad one can add up to thousands of dollars. Same car, different price.

It reaches past loans too. A landlord often checks it before handing you an apartment. A utility company may check it to set your deposit. Some employers glance at a version of it before they hire. Your credit is your money reputation, and a lot of doors open or close on it.

Your score is built from five parts. Each one carries a different weight. Once you know them, the score stops being a mystery.

• On-time payments, about 35%. The biggest piece by far. Pay every bill by its due date and you feed the largest part of your score every single month.
• How much of your limit you use, about 30%. This is your credit utilization. If your card limit is $1,000 and you owe $300, you are at 30%. Lower is better. Under 30% helps, and under 10% helps more.
• Age of your credit, about 15%. How long your accounts have been open. Old accounts are gold, so keep them open and let time work for you.
• Your mix, about 10%. Having more than one kind, like a card and a small loan. Minor, so do not chase it.
• New credit, about 10%. Opening a bunch of new accounts at once looks risky. Space out your applications.

On-time payments and how much of your limit you use make up about 65% of the whole thing. Nail those two and most of the score takes care of itself.

If you have never borrowed, you have no track record, so there is nothing to score yet. That is normal. There are a few plain ways to start one.

A secured card is the most common first step. You put down a deposit, say $200, and that deposit becomes your limit. You use the card for one small bill and pay it in full each month. The card reports that on-time history for you. After a while, many issuers hand your deposit back and turn it into a regular card.

A credit-builder loan is another path. A lender holds a small sum. You make steady monthly payments that get reported. At the end, you get the money back. You are basically paying to build a track record.

Becoming an authorized user is a third way. Someone with good credit, a parent or a partner, adds you to their card. Their good history can then show up on your record. Pick a person who pays on time, because their habits land on you either way.

You get one free look at your full credit report every year, from each of the three big credit bureaus. Those are the companies that keep your record. The one site that is truly free is AnnualCreditReport.com. That is the real one. Other sites may charge you or sign you up for something.

Read it slowly and hunt for mistakes. Accounts you never opened. A balance that is wrong. A bill marked late that you paid on time. Errors are common, and every error can drag your score down for no reason.

If you find one, you dispute it. You tell the bureau in writing what is wrong and why. They have to look into it, usually within 30 days, and fix or remove what they cannot prove. It is free, and you do not need to pay anyone to do it for you.

A lot of credit advice out there is flat wrong. Let us clear the big ones.

Myth: checking your own score hurts it. False. Looking at your own score or report never lowers it. Check it all you want. Only a lender checking it to lend you money leaves a small mark, and even that is minor.

Myth: you must carry a balance to build credit. False, and this one costs people real money. You do not need to leave a balance sitting on the card paying interest. Paying in full every month builds your score just as well, and it costs you nothing.

Myth: you need to be in debt to have credit. False. Using a card and paying it off is a different thing from being in debt. You can hold a strong score while owing nothing at month end.

Myth: one late payment ruins you forever. It hurts, yes. It does not last forever, though. As on-time months stack up behind it, the damage fades. Time and steady payments heal it.

Myth: closing an old card helps. Usually the opposite. Closing a card can shorten your credit age and shrink your total limit, which pushes your utilization up. Often the better move is to keep an old card open and use it lightly.

Not all debt is the same. Some can build your life. Some can bury it. Knowing the difference protects you.

Good debt tends to buy something that grows or earns: a home that can gain value, a skill that raises your pay. The rate is usually low, and the thing outlasts the loan.

Bad debt buys something that shrinks or disappears while you pay for it, at a high rate. The worst of it hides in two places. Payday loans charge fees that work out to rates in the triple digits. They roll over until a small shortfall becomes a deep hole. Rent-to-own stores let you take a couch or a TV home for small weekly payments. By the end, they charge you two or three times what the item costs. Both prey on people who need something right now. Walk around them when you can.

If you already carry debt, there are two clean ways to attack it. The snowball: pay the smallest balance first while paying the minimum on the rest. Then roll that freed-up payment onto the next smallest. You get quick wins that keep you going. The avalanche: pay the highest-rate debt first, which saves you the most money over time. Both work. The best one is the one you will actually stick with.
