Experian FICO 3 -- 30 point score drop explanation?

[GZG]

any ideas of what causes Experian FICO 3 to drop when all other experian scores don't fall nearly as far?

Experian FICO 2 is only down 10 points, FICO 8/9 are up, report is still clean

no new accounts, no new inquiries (from when the score was ~786) still ~1-2% reported with AZE3-4, SSL is still all good, not paid off 

AAoA hit 11 years? AAoA nearing 6 years?

extremely sensitive to # accounts reporting and utilization?  

curious what I could be missing, reason codes don't seem to have changed much: 

old: 

new:

Do you have any AU accounts?

EX score 2 is based on the Fico 98 model. EX score 3 is based on the Fico 04 model. EQ score 5 and TU score 4 are based on the Fico 04 model.

My experience is TU and EQ scores based on the Fico 04 model are sensitive to #/% of cards with balances. Score sensitivity to cards with balances was heightened when I had a recent inquiry on these files. I suspect EX score 3 may also have heightened sensitivity to cards with balances given you have new credit.

EX Fico 8, 9 and 10 scores don't react much to increases in qty of cards with balances. EX Fico 98 (score 2) has a rather muted response as well.

I'd say the new account under 12 months coupled with seeking credit HPs are the primary score drop triggers and they may have amped up the penalty for accounts with balances.

Notes:

1. "new account" suggests new. "New account relative recently" can mean anytime in the last 5 years.

2. "Seeking credit" means hard inquiry. "You've recently been looking for credit" means HPs in the last 12 months.

3. "Accounts with balances" relates to quantity.

4. "Short revolving history" means insufficient age on your oldest revolving account. Did your oldest revolver drop off your report or were you removed as AU on an old account?

Granted I'm not on a clean profile, but I when I opened my last account on 4/12/24 I didn't lose anywhere near that much for the account and associated HP. My aggregate utilization has dropped from 10.9% at the time of approval to 7.5%, so that may be a couple points (I only lost 2 pts when before applying when I went up to 10.9%), but am reporting 3/6 cards now and am only 4 pts below my EX3 score when I applied.  (EX3 is now 693 vs 697).

Agree. Opening a new account if you already have a new one under 12 months generally only costs a INQ since the new account penalty is in play.

2 of 6 to 3 of 6 often costs no points as well. Penalty really starts to kick in at 5 of 6 and moreso at 6 of 6 with balances. Also, it is listed 4th for the OP. Usually the top 2 codes have the dominant impact on score.

In the OP's case that's "short revolving history" and "new account". Thus the question on losing an old AU account. That would typically not hurt Fico 8 and newer models but could hurt EX score 3 (likely EX score 2 as well). 

I have no idea what is triggering the new account reason. We can only comment based on info provided.

A big difference between EX score 2/3 and newer models is the treatment of AU accounts. A significant difference between EX score 2 ans EX score 3 is the treatment of NPSL charge cards.

Unfortunately there is no comparitive data for EQ score 5 and TU score 4 which are derived from the same base model as EX score 3.

I never think much about FICO 3, for obvious reasons, but your thread got me thinking. When I ran my test on whether AoYA was really AoYA or AoYRA, I came to the conclusion that it was AoYA for FICO 2, 4, and 5, but AoYRA for the more modern scores FICO 8, 9, and 10, on all 3 bureaus. I just went back to see how EX FICO 3 behaved, and it behaved like the more modern models -- the addition of a new installment loan had no effect.
