There are few numbers in life that matter as much to your financial outlook and well-being as your credit score. However, confusion is the norm for consumers when it comes to this important financial gauge.

The History of Credit Scores

Prior to the creation of standardized credit scores, lenders and loan officers would often develop their own "score card" to assess the risk of lending to a particular borrower. This score card could vary drastically from one lender to the next. The major issue with this original method was that it was based on a loan officer's ability to judge risk, rather than a common set of rules and specific calculations.

So, in the 1980's, the Fair Isaac Corporation set up the first general purpose credit scoring system based on credit bureau information in order to help remove the inherent inconsistencies that arose from having each lender perform their own credit diagnostics. It has since become known as the FICO score and the algorithm has been widely adopted by America's largest credit reporting agencies.

Why would my score differ between credit agencies?

The three major credit bureaus are Equifax, Experian and TransUnion. If you're seeing different scores from each bureau, there could be a few reasons for this. Here are some of the most common ones.

  1. The scores are from different dates. Since your score can change at any time, it's important to compare credit scores from the same date.
  2. The scores were calculated using different scoring models. We'll get into this in the next section, but it's important to know that there are many scoring models out there. When you compare scores among bureaus, make sure they are calculated using the same model. Even with the same model, your scores could vary because each bureau may store information or calculate the score a little differently.
  3. The information in your credit reports varies among credit bureaus. This actually isn't uncommon. Some lenders report to all three credit bureaus, but others report to just two or one or none at all. The information in your credit reports may also be updated at different times at each bureau. In other words, one credit bureau may be missing an account or other information that either helps or hinders your score.

Of course, it's also a good idea to check your credit reports for errors periodically since an error could affect your score. You can check your TransUnion and Equifax credit reports for free on Credit Karma and your Experian report on www.AnnualCreditReport.com.

Why would my score differ between the same credit agency?

Like a thumbprint, no credit score model is exactly the same. Each credit score model has a slightly different formula for weighing credit score factors. The credit bureau can use dozens of different credit score models based on the requirements of different lenders. As an example, a mortgage lender may use a different scoring model than an auto lender because they each place importance on different factors.

Though your scores may vary, they're all based on information in your credit reports. So focusing on what's in your reports could help you build your credit overall.

Other Available Scores

While FICO is the most famous, there are several other versions and providers of credit scores, such as VantageScore, NextGen, BEACON and EMPIRICA. Some scores are directly developed by credit bureaus, while others are developed by outside companies.

Is there a "best score"?

In a word, no. In order to protect revenues, credit reporting agencies will often position their scores as the best or the most predictive. In reality, all scores must adhere to similar guidelines to be truly predictive, regardless of the final output number. All credit scores are built from the same base set of data and statistical procedures.

Like many products and services in the marketplace, there are a plethora of different options for you (and the businesses that serve you) to choose from, simply because every buyer is different. Based on cost and effectiveness in each buying situation, there are credit scores for sale to satisfy each customer.

Score Ranges

Just as a point of reference, it may be important for you to know what the score ranges are for each of the major scoring systems. The higher your score, the better, as it is a general gauge of your overall creditworthiness in the eyes of lenders.

  • FICO Score: 300 -850
  • Score from Experian: 330-830
  • Score from Equifax: 300-850
  • Score from TransUnion: 300-850
  • VantageScore 3.0: 300-850

Bottom Line

Because there are hundreds of credit scores that measure many different probabilities, consumers generally do not need to be overly concerned with the type of score or even their number. It's also important to note that your credit score is a variable which can change every time your credit report changes. For these reasons, monitoring changes within a single score over time can be a better way to gauge your overall credit health.

These complicated facets of credit scores are exactly why we developed Credit Karma. By keeping the bureau and credit scoring model consistent, we are hoping to provide consumers with a single, easier-to-follow point of reference on their credit health. Best of all, it's always free to check your credit score with us. In this way, you can access your score as often as you want and always have a consistent baseline to better understand how your score is changing.

Why does my vantagescore take 10 point hit for showing a $171 balance on a discovercard with a $30k limit ?

Transrisk score didnt & doesnt change.  Your page indicates some revolving debt is better than none but vantagescore CLEARLY penalizes me for even a miniscule amount. $171 on a $30k card and of $85k total revolving accounts.

I can & will pay it off every month prior to the statement date but I thought not doing so would help my score,not hurt it.

What other scores?

I am not so much interested in how I compare to the rest of the world as in where I fall in the ranges you are using. In other words, which of these are you using?

FICO: traditionally between 300 and 850.

Experian: 330 - 830

Equifax: 300 - 850

TransUnion: 150 - 950

VantageScore: 501 - 990 (often assigned a letter grade, A - F)

My CK score started out at 589 about 6 months ago.

I got a prepaid Capital One card and within a couple of months my score went up to 609 and eventually 618 where it is now.

I recently had my credit pulled in order to buy a house and my actual FICO is 676.

High enough to qualify for a mortgage.

I had known from this article that there was a difference between the different credit reports.

My Experian score is now 665 by way of Credit Inform, which is a service from Capital One.

It started out at 634.

My Equifax score last month was 632. I had to purchase that one.

Since there is a large difference between the scores,

don't get discouraged with a low CK score.

It seems to be the lowest of the 3, so it you can get it to improve, the other scores will be substantially higher.

i agree with most everyone else on this forum. does credit karma simply take the credit report from TransUnion and make their own score? because when i applied for a Sallie Mae loan (which i got denied from. not sure if it was because i applied before the whole debt ceiling negotiations or because of my short credit history. probably a good mix of both), apparently my credit score was 733. creditsesame pulls my experian and my score on there is 738. but creditkarma says my score is 689. that's a PRETTY big difference, especially since TransUnion says i have a 733!!!

From what I understand Credit Karma is using TransUnion to determine the score -- at least on Feb. 16 they are...

I see above that Karma uses Transunion as their provider. Why would my score not be reported as the same between Karma (742) and Transunion (726). Moreover, the other two agencies report my score even lower with both coming in at 705...

This article explains the reasons why. Lastly, TrueCredit uses Vantage and Credit Karma uses TransRisk.

My credit was excellent ten years ago until my divorce, should I be held accountable for another individual opening up credit cards in my name and not paying them, not to mention not paying a car payment that I was paying her monthly to do? I would say not. Do people realize and there are multiple articles written about this, forty two percent of all negative reporting done on credit bureaus are either wrong or false. You would need forty eight hours in a day to keep up. Now here is a question to ponder, if the reporting is wrong forty two percent of the time and a credit bureau can’t dictate a recession, divorce, accident, illness, loss of employment, life great accidents, then why are they in place? Legalized interest extortion, something to ponder.

shouldnt have open'd them in your name for someone else. Its not the lenders fault that you personal life didnt go right. consider going ofter your spouse in court and having him/her pay them.

My credit is score is very poor! The main thing that I have on my credit is medical bills. I didn't think that medical could show up and or effect your credit score! Is there any way to get around the medical bills to improve my score?????

I was in the same position. Try to work out with the medical provider, they work with you. A plan with installment payments will work best, this way, the provider will clear your name from the credit bureau and you are not burdend with all the payments at one time.
