(CNN) Your credit score could soon go down -- or up.

FICO announced Thursday its latest version of the FICO score, a three-digit number that assesses a person's credit risk . The new scoring model will take consumers' debt levels into account and will more closely track personal loans.

Previous scoring models took snapshots of a person's payment history. The new model will take a historical view of payments over time and can process much more information, including account balances for the previous two years, aiming to give lenders more insight into how individuals are managing their credit, FICO said.

About 80 million people will see a shift of 20 points or more, according to a statement from Dave Shellenberger, vice president of product management at FICO. Of those, about half will see scores go up, while the other half will see their scores drop.

Those who have a high amount of credit card debt relative to their overall credit, or who have recently missed payments, could see a more significant drop.
