@Anonymous wrote:For those that checked their scores just before their youngest account reached 1 year and then again after, what type of increase did you see scoring wise? What was your AoOA and AAoA as well? I'm a couple of months away from my youngest account hitting 1 year, but more than likely I'll app again before that point in time arrives so I'm doubtful I'll be able to test this datapoint myself any time soon.
On my dirty file, I got nothing for Age of Youngest Account going over a year: Dixie Flatline style, FICO 04 and FICO 8 models. Was tracking everything with lots of datapoints on a zealously fixed during my mortgage process, and happened to tick beyond the 1 year mark on my most recent account. AAOA was somewhere north of 2 years at the time, oldest account was from 08 so that would've been roughly 7 years at the time.
May be different on clean files to be sure.
@Anonymous wrote:Very interesting question. I have been wondering that myself. I track my FICO scores and credit on a weekly basis and have been for almost 2 years. Your question is exactly what I was looking at for this month. Last year in March I applied for and was approved for 4 credit cards. 2 on 03/27, 1 on 03/28 and one on 03/30. I was also wondering if my scores would get a bump on my one year anniversary because FICO does not include hard inquiries in their FICO 8 scoring model after 1 year (but they do stay on your report for another year), and my 4 tradelines would hit the 1 year mark.
To give a little history about my credit profile, I have 16 tradelines – 2 mortgages, 1 student loan (my sons), and 13 credit cards. All my credit cards every single month always report $0 balance (I pay them off before they hit the credit bureaus). My mortgages and co-signed student loan drop a little each month. Not much changes in my FICO reports and scores each month. However, I was looking forward to this month because those 4 accounts reaching the 1 year mark, and those 4 hard inquires dropping from the FICO 8 scoring model.
Today I saw your question and decided to order a 3 bureau report. My FICO scores on March 26th were Experian: 797 Equifax: 803 Transunion: 809. Today March 28 they are – Experian: 811 Equifax: 816 and Transunion: 809.
Experian breakdown. On March 26 my score was 797. I had 3 hard inquiries due to come off this month (1 year). 2 on 03/27 and 1 on 03/28. I checked my score yesterday 03/27 and it had jumped to 807. Today I checked and it had jumped to 811. Because my credit report does not change much due to always having a $0 balance on all my credit cards, I can only assume that the 1 year Hard inquiry drop and the tradelines becoming a year old were responsible for the 14 point bump in score. 4 to 5 point jump for each one. Yesterday when 2 accounts aged 1 year and Hard inquiry drop, I got a 10 point bump (5 points each), and today when 1 account aged 1 year and 1 hard inquiry drop I got a 4 point bump.
Equifax breakdown. On March 26 my score was 803. I had 2 hard inquires due to come off this month and the same 2 tradelines to age 1 year – 1 on 03/27 and 1 on 03/28. Today March 28 my score jumped to 816. Apply same logic above under Experian breakdown. The only difference is for Equifax my score jumped an average of 8 points per tradeline reaching 1 year and both hard inquires no longer included in the FICO 8 scoring model.
Transunion breakdown. Very interesting for this one. My FICO scores stayed the same from March 26 809 to today 809. I have 1 tradeline aging a year on 03/30 and its accompanying hard inquiry being dropped from FICO 8 scoring model on that same day. So no change activity to report for Transunion because it hasn’t reached 03/30 yet (Friday). This kind of supports the logic above and bumps in scores for Experian and Equifax but NOT Transunion.
Everyone’s credit profile is different and I am not saying this will happen for you. But, for me, I believe that the 1 year AoYA and the Hard Inquiries dropping from FICO 8 scoring model gave me a nice bump in scores. I will look at my Transunion score on 03/30 and see if I get at 4 to 8 point bump. Would be nice.
Great info above! Thanks for taking the time to post.
I guess the tough thing to consider here is that since there are 2 variables reaching the 1 year mark (Inquirie(s) and AoYA) it's impossible to decipher how many points each one is "worth" when considering the increase. I'd tend to think that the AoYA reaching 1 year matters more scoring wise than year-old inquiries. From my experience in the past, getting hit with inquiries often only impacts score a couple of points, then more points can be lost when the "new account" reports. If the inquiry itself though is only worth say 3 points at the time it happens, I'd think that in a year it's probably only impacting score maybe a point, if at all actually. From my experience it seemed like any points lost from inquiries AND new accounts came back in 4-6 months. Obviously there are other factors at play, but that's always been my feeling on it.
I'll be curious to see what happens with your TU score in the next week or so.
Also, out of curiosity, you said that you always make sure all of your credit cards report zero balances. Have you ever let one of them report a small balance to see what type of score bump you'd get? Typically many find it to be in the 15-20 point range, which would yield you some sweet 820's-830's more than likely 
@Anonymous wrote:The different bureaus can weigh pieces of the FICO puzzle slightly differently I believe. So one bureau may give a few more points of value to a certain event happening compared to that identical event on another bureau.
I'm curious as to why you think inquiries at the 1 year mark are carrying so much weight/value? As I said earlier, I've never seen an inquiry impact my score more than 2-3 points and that was right when it happened. Within 4-6 months IMO all points were recovered. I wouldn't think at the 1 year mark there would be any points gained back other than maybe 1 per inquiry. Of course it depends on your profile, but I think a reasonably thick file wouldn't be impacted much if at all at the 1 year mark due to inquiries falling off. There have been people with a ton of inquiries (double-digit+) that have felt they weren't impacting their score inside of a year.
Well for EQ FICO 5 I can state emphatically they count for the entire year.
This can be tested if one spaces out some applications over a year if you know where a breakpoint is. For example on EQ FICO 5 (a FICO 04 model) if I'm at 2 inquires I'm at 700, if I'm at 3 inquiries I'm at 693. This has been accurate for over the past 2 years that I've basically been flatlined on that particular score.
Specifically:
Was at 700 and 2 inquiries.
Took mortgage inquiry, 30 days later (grace period) at 3 inquiries down to 693.
An inquiry from a rental application fell off, back to 700
Took another mortgage inquiry, non-dedupe, 30 day grace period back to 693.
An inquiry from VZW dropped off, back to 700.
Went on a spree post closing, took some inquiries on EQ, back to 693 and I'm still stuck on that score as of last month with 4 inquiries counting on EQ.
That's pretty conclusive data that inquiries count for the entire year that they're on there, sum up, sort into a bin, allocate penalty based on which bin you fall into... the penalty is assuredly dependent on scorecard, but I truly doubt the mechanics are any different when we're talking algorithm implementation. I doubt this has changed for FICO 8 either, I've never understood people's comments that inquiry damage fades after a year as most people's files are way too busy to really test it concretely and most don't garden for a year on a fixed file (where age / thickness and in my case a negative which may or may not be needed limiting my scorecard to some theoretical maximum) to stringently test it. It's actually really hard to test.
