These FICO Secrets Could Be Hurting Your Credit Score

Discover what credit reporting bureaus don’t like to tell you. These hidden gems will help you improve your score and keep you from making mistakes that you don’t even know can hurt your credit score.

Do you know your FICO score? The Fair Isaac Corporation, or FICO, is the standard credit risk score used by 90% of the banking, credit card, mortgage, auto and retail industries. Your score affects many aspects of your financial life, from the interest rates you pay to the ability to rent an apartment, get hired for a job and more. According to, credit scores range between 300 and 850, with 850 being the best.

Generally speaking, a score below 620 is considered to be a sub-prime category where borrowers will pay much higher interest rates while a score of 720 or higher typically rewards consumers with the best rates. Frequently when you see ads for low interest rates on purchases, the small disclaimer will require a 720 or 730 score or higher to get the low rates or best deals.

Many people know that paying bills on time is typically the most important and obvious factor in building and keeping a good credit score but may not know how – and why – other aspects of their financial history also play a large part in determining their scores. There may be a few surprises.

Credit Score Building Blocks

hidden-score-elements-2 The general construction of a credit score consists of five categories, although the final impact of each depends on one’s overall financial history and how FICO places you within one of their 12 score cards models. Some financial activities may add points to your credit score and others may subtract points.

35%: Payment history – pay bills on time. A 30-day delinquency could lower your score by 60 to 110 points according to

30%: Capacity available – a ratio of your credit balances to your total available credit. The more capacity available, the better. In other words, maxed out credit is bad for your score.

15%: Length of credit – uses the average age of your credit lines factoring in your oldest established credit. Keeping your oldest revolving credit accounts open, even if mostly unused, helps to sustain a higher score.

10%: Accumulation of recent credit – new credit accounts and credit inquiries can cause you to lose points off your score and several together in a short time period is worse.

10%: Mix of installment versus revolving credit – you’re better off having more in revolving credit than installment credit and/or a good mix of credit types is preferable to just having one type.

Surprising “Gotcha”

We’ve all seen the deals from furniture, appliance and electronics stores declaring, “Pay no interest for 24 months,” or, “Same as cash” offers. One would naturally think that paying no interest by financing directly through the store makes sense, but wait. According to most experts including the Dupaco Credit Union and the Federal Trade Commission, this type of financing is generally offered through a finance company, considered to be a “lender of last resort” and as such, can hurt your score. Finance companies typically deal with sub-prime borrowers and several such purchases can have an increasingly negative impact on your score.

Other Hidden Elements of Your Score

hidden-score-elements-3 Do When you first begin a credit history, you, of course, have a minimum length of credit time value. It takes several years for this value to reach its maximum assuming there are no recent new hard credit inquiries or credit accounts. When you add new credit, it can temporarily lower your score as part of the accumulation of new credit scoring factor.

Just one derogatory public record can severely impact your credit score with the depth of the impact depending on your existing score and your FICO scorecard category. According to, derogatory public records can be bankruptcy filings, tax liens, and judgments or collection items and these can take from 7 ½ to 15 years to completely roll off your history.

Here’s another “gotcha.” When applying for credit, you may be wrongly advised to pay off an old medical collection bill, for example. Paying off a dormant bill can reset the timing counter from an aging derogatory obligation to a current one and could cost you significant points off your credit score simply because there was new activity on the unpaid obligation that had been aging off your score.

Have some credit? Use it wisely. A key credit score factor is how you build and use your overall credit capacity or debt utilization rate. According to an article in, a utilization rate of 10% or less is highly desired. In other words, if you have $10,000 in total credit line availability, try to keep your actual total balances below $1,000. A lower utilization rate is even better.

Summary and Where to Learn More

hidden-score-elements-4 Do As you can see, even just a few well-intentioned acts could easily damage your credit score and cause you to pay much higher interest rates. In summary:

  • In general, say no to new, unsolicited or unwanted offers of credit or credit cards.

What difference does your credit score really make? The out of pocket difference between having a 530 FICO score and a 730 score could easily exceed $250,000 or more over your credit lifetime depending on your habits and utilization of credit.
