When it comes to credit scores, there’s almost always room for improvement. If you’ve pulled your score and you’re not satisfied with the number you received, there are several strategies to boost it. But first, you need a little insight into how that score is calculated.

How is My Score Generated?

VantageScore, the company that generates the credit score you see here, uses five major categories of information, all of which were reported to the credit bureaus by your lenders to generate scores that range from 350 to 850 (higher is better, of course).

Each category is weighed differently. Here’s how your VantageScore* breaks down:

40% Payment History. Lenders want to see a history of consistent, on-time payments.

23% Credit Usage. Also known as credit utilization, is the ratio between the total balance you owe and your total credit limit on your accounts.

• Tip:  Try to keep your credit utilization at 30 percent or below. The reason is that if you are consistently maxing out your credit cards, it may look like a sign of desperation in the eyes of a lender.

21% Credit Age. This is the age and type of credit you have. This percentage factors into how long you’ve had different kinds of credit accounts open. The older your credit history, the better.

11% Account Mix. Your credit account mix considers the number and type of accounts you have. Your score may be higher if you have a mix of both installment credit, like mortgages or car loans, and revolving credit, like credit cards.

5% Inquiries. This is based on recent credit applications. Opening multiple credit accounts in a short period could represent a greater risk for lenders — multiple recent inquiries may worry lenders that you are applying to so many places because you are unable to qualify for credit — or because you need money in a pinch — so avoid opening too many accounts too quickly.

• Tip: You don’t have to worry about this if you’re shopping for a mortgage or car loan. All inquiries within 14 days count as a single inquiry.

Raise Your Score by Doing the Following:

• Pull your credit reports. The three major credit scoring bureaus, TransUnion, Equifax, and Experian, will each allow you one free copy of your report each week. Plus, if your financial institution is a SavvyMoney partner you have access to your report and score daily. If you get a copy directly from the credit scoring bureaus I suggest spreading them out by pulling one every four months). If you find an error in your report, you should dispute it. Simple mistakes – the wrong address or a misspelling of your name – can be fixed by calling the creditor and asking for an update. If they won’t oblige, or the error is more complicated, you should dispute directly with the credit bureaus. You can do this online.

• Pay your bills on time. One day late is still considered late, and just one late payment can lower your score.

• Pay down credit card debt. You don’t want to be using more than 30% of the total credit available to you. Keeping your utilization well below that (closer to 10%) can give your score a boost.

• Hang onto old cards. Your credit score benefits from long relationships with lenders, so cut them up, but don’t cancel them if you can help it.

• Be thoughtful about shopping for new credit. Every time you apply for a new card or loan, the lender takes a peek at your credit history, which may ding your score.

• Spread your debts around. The mix of credit you have in your file—mortgages, student loans, auto loans, credit cards—shows that you can manage debt from multiple sources.

Remember that time – and patience – are key. You shouldn’t expect a change overnight, but you will see improvement over the course of 12 to 18 months – shorter, if your score is already fairly high and you’re just looking for a bit of a jump.
