Your credit score is a three-digit number that follows you around. It affects whether you can rent an apartment, get a car loan, or qualify for a credit card. A higher score means better options and lower costs. A lower score means fewer choices and higher interest rates.

The good news is your score isn't fixed. It moves. And the things that move it are things you can control.

What a credit score actually is

Your credit score is calculated from your credit history. It's a snapshot of how reliably you've borrowed and repaid money over time.

Scores range from 300 to 850. Most lenders consider anything above 670 good. Above 740 is very good. Below 580 makes it hard to qualify for most things without a cosigner or a deposit.

You don't need a perfect score. You just need one that's moving in the right direction.

What goes into your score

Five things make up your score. Two of them matter most.

Payment history is the biggest factor. It's about 35% of your score. Pay on time and your score goes up. Miss a payment and it drops. Even one missed payment can hurt your score for years.

Credit utilization is the second biggest factor. About 30%. This is how much of your available credit you're using. If your credit card limit is $500 and you have a $400 balance, your utilization is 80%. That's too high. Keeping it below 30% helps your score. Below 10% is even better.

The other three factors are length of credit history, the mix of accounts you have, and how often you apply for new credit. These matter but they're harder to control in the short term.

The fastest ways to move your score

Pay every bill on time. Set up autopay for the minimum if you have to. A single late payment does more damage than most people expect.

Pay down balances on credit cards. Even getting from 80% utilization to 50% can move your score noticeably within a month or two.

Don't close old accounts. Length of credit history matters. An old card you don't use is still helping your score by existing.

Don't apply for several new accounts at once. Every application triggers a hard inquiry that dips your score slightly. Space them out.

If you don't have much credit history

Building credit from scratch takes time but it's straightforward. A secured credit card, where you put down a deposit that becomes your credit limit, is the most common starting point. Use it for small purchases and pay it off every month. After six to twelve months of on-time payments, your score starts to build.
