Normally your credit score updates at the soonest every month, sometimes longer. This can make it seem like something drastic has happened when in reality it could have been something that happened over that time period. Things that can have a significant impact on your score are maxing out your credit, missing a payment, applying for credit too often, or sometimes closing of accounts. You should use a credit monitoring tool that allows you to see exactly what caused the change and why. Credit karma, the turbotax credit score software from intuit, and many other free options are out there. This will help take the guesswork out of your situation and will most likely give you steps to rectify the problem.
