Although there are several credit models, the most commonly used is FICO, based on a model created by Fair, Isaac Company. Their consumer website is myfico.com, and you can find information about the FICO credit scores there.

Your FICO credit score can be used to determine your interest rate and how much credit a lender will give you. So taking care of your score, and keeping your credit clean will save you money.

Getting and improving your credit score is not hard at all, just takes time. Here is a tip or two that will help you improve and increase your score.

FIRST: Get a copy of your Credit History

There are many reasons you may have no credit history. Maybe you're just starting out, maybe you pay cash for everything and have never needed a loan. In any case, if you have no credit history, your FICO score is likely to be low.

A fast and easy way to improve or start a credit history is to get a loan and pay it off on time. "Installment loans" are looked at as more important than credit cards. You will show a stronger score if your installment loans are paid up to date and on time then say a consumer credit card.

Another way to acquire a better credit history is to take $1000 and open a 6 month CD account at a financial institution. Now, get an installment loan for $1000, using that CD as collateral. Now, here's the trick. Take the $1000 loan, and open another 6 month CD account at another institution. Take another loan for the $1000 at the second institution. Do this one more time.

Let the CD's mature, paying only the minimum for the 6 months. Once they mature you cash them out and pay off all three loans. Congratulations...you now have a credit history.

SECOND: Maintain Your Good Credit History

Good job - you have paid your bills on time, and do not have high credit card debt. Here's some ideas to keep your FICO score as high as possible.

You don't need to close old accounts. (Unless you're being charged a fee to keep the account open.) Part of the FICO formula is based on the amount of credit available vs. how much you have used.

Another thing to be aware of is how you manage your money. Here's the scenario: you have a $2000 credit card. Every month, you charge about $1800 to that card. And, every month you pay it off. But here's what happens - your credit card company reports your credit information monthly to FICO. However if they report it on the day before you pay it off...the credit agency sees you carry a balance every month. If you can try changing the days you pay off your credit card.

THIRD: Fix your bad credit

Ok we all at some point have poor credit history. However you can improve your score. It takes time but can be done. If you're really unsure of the steps you need to take contact a credit counselor. You can find several good services offered online.

The most heavily weighted part of your score is based on your payment history. The first thing to do to start repairing your credit history is to pay your bills on time. The mortgage is the most important, followed by installment loans, and finally credit cards.

The next largest factor on your credit is how you have used it. You can improve it by paying off your credit cards.

At the end of all this, make sure you review your credit report. Get one report from all three credit agencies. Read every page. (I know it reads like stereo instructions in Greek) Look at the entries and call and contact the creditors to have them remove any errors.

Your FICO score is an important part of your financial life, and using these strategies may help improve your FICO score. Before making any drastic changes to your finances, consult with a financial advisor.
