What is Credit Karma?

Established in 2007, Credit Karma* provides a way for people to access their credit report for free. Unlike Experian, Equifax or TransUnion, it doesn't create the credit reports or calculate a credit score. Instead, it uses data given to it by TransUnion, which is updated weekly, and passes that on to users. In addition, it alerts people if their TransUnion credit score has changed because of new entries being added to their report, as well as suggesting ways to improve the overall score.

Credit Karma states it doesn't - and will never - sell users' data to third-party companies. However, it does work as a credit broker, presenting its customers with loans and credit card deals from a number of financial institutions and earning commission on sales of those products. From the consumers' point of view, Credit Karma is free and it can help identify credit products that they are likely to be accepted for based on their TransUnion credit report. However, it lacks some of the features offered by other credit-reference companies, particularly those with paid subscriptions.

Credit Karma key features

  • Sends a free weekly credit report to users, based on data from TransUnion
  • Suggests ways to improve TransUnion credit score
  • Works as a broker, matching financial products from its panel of lenders to customers, based on the credit scores it has for them
  • Provides a free eligibility checker to give a good indication of whether someone is likely to be approved for the credit products it markets
  • Has an energy-switching service to help reduce energy bills
  • Notifies users of any changes to their credit report

How does Credit Karma work?

In terms of providing credit reports, Credit Karma presents the information it sources from TransUnion, which is based on people's past financial behaviour, as well their current credit agreements. This is updated weekly and users can also receive notifications if their credit report or score with the agency changes. This is important as lenders use the information contained in credit reports from TransUnion, Equifax and Experian to decide whether to approve applications for products such as mortgages, loans or credit cards. If you have a poor credit rating, you are less likely to be approved, be offered a low interest rate or get a high credit limit.

The way Credit Karma makes money is by acting as a credit broker, working with a panel of lenders to match users' credit ratings with products they are likely to be accepted for. If people take out these products, Credit Karma earns commission. From a consumer's perspective, it can be useful to know how likely you are to be approved for credit before you apply for it as, if you are turned down, it can have a further negative effect on your credit score. With this in mind, Credit Karma has an eligibility checker, giving approval odds of between 10-95% to show you whether you are likely to be successful. There is also an indication of whether you have 100% approval odds, although this doesn't act as a guarantee. If you don't meet the lender's criteria outside of your credit rating - for example, if you already have a product with them - you may still be turned down.

Is Credit Karma accurate?

As Credit Karma sources its credit report data direct from TransUnion, it doesn't control the accuracy of the information it provides. However, while there may be errors in your report or out-of-date entries, Credit Karma does have a mechanism in place to resolve those types of issues. If you notice a mistake, it's a good idea to contact both Credit Karma and TransUnion to inform them as correcting it could help to improve your credit rating.

In general, it pays to check your reports with all three credit reference agencies - Experian, Equifax and TransUnion - so you have a full picture of your financial health. As they each have access to information from different lenders and other official sources, there may be discrepancies across all three and, unless you are aware and can correct the errors, you will be at greater risk of unexpectedly being turned down for credit in the future.

Credit Karma pros and cons


  • It's free to use and doesn't require you to provide your debit or credit card details to sign up
  • It gives you an indication of how likely you are to be accepted for certain credit products, reducing the chances of you being turned down, which could have a detrimental effect on your credit file
  • It includes an energy-switching service, which can help reduce your energy bills


  • It doesn't offer a distinct identity protection element in the same way as Experian and Equifax do
  • It doesn't have a facility to let you improve your TransUnion credit score, while Experian has this through Experian Boost
  • It is still necessary to check your reports with Experian and Equifax to make sure you have insight into any potential problems before applying for credit in the future

Should you sign up with Credit Karma?

Credit Karma is free, so there is little downside to signing up in order to check your TransUnion credit report. You will be able to see products that your credit file suggests are a good fit for your finances and check out tips to improve your TransUnion credit score. However, it you are only planning a one-off check of your credit score, there may be free trials on other services that give you more insight and access to other credit unions beyond TransUnion.

Alternatives to Credit Karma
