quarterly vs. monthly app(s)
 

General wisdom seems to be that it is better for your credit score to apply for a bunch of cards on the same day (quarterly?) than to space them out one or two per month. Is this a theory or proven? How does quarterly affect your score differently than monthly if the total number of cards applied for ends up being equal? Where can I find information/discussion that supports this or can someone chime in on the reasoning behind it? Appreciate the input! Thanks.

Based on what I've seen, I doubt it matters much at all.

A credit pull dings your credit score by maybe a point or two, and it rebounds over time. I space my card applications so that I can make the minimum spends, I have never applied for two on the same day, and I have never gotten turned down (except once when Chase said I had too much credit, and then they just transferred part of my line from one card to another). I really think most people worry too much about applications and their credit scores. Now maybe if my credit score was borderline I might worry more.

It makes no difference to your credit score over the long run. It just increases your chance to get approved. If you do a churn every 6 months as I do, it is much better to have 4-5 inquires that are all 6 months old than 4-5 inquires that are anywhere from 1 month to 6 months old. Inquires older than 6 months supposedly have less effect on your score. If you apply every 3 months, it probably makes less of a difference but still helps.

i try to apply all cards on same day ,so that they all fall of same month.so far none of the card got rejected ,some needed to call recon line to get approved.

I think the reason why most prefer quarterly or semi annual churns is because inquiries seems to matter less over time. So if you plan to get 12 cards a year you could do one a month but after the first few months you'd always have several recent queries on your credit statement. But if you did six cards twice a year you will have no recent i inquiries when you apply for new cards thus increasing your score, how the card companies view you and your chances.
