I did some searching and found a few older threads with varying opnions on this one, but if memory serves, I think I remember a penalty of sorts negatively affecting one's Fico score for some time after opening a new account.
As it's been about five months since I last opened an account, I'm hoping for a score bump sometime next month...
Does that sound right?
Your ding on your score has to do with a few things. First of all it is a credit inquiry, having those will lower your score. Second, New accounts lower your account age average. Lastly If you carry a balance it could lower your score due to Credit Utilization. So to say it will come right back on a set time frame is hard to say. After I have opened accounts it has taken between 6 months to a year to come all the way back! My credit history is long so a new card doesn't afftect my credit age much. If you are new to credit then a new cc could cut your age in half.
My opinion around 6 months you should start to see the increase again.
Hope that helps!
Good Luck
