Total Balance Owed Thresholds

[Zoostation1]

I have a dirty revolver only profile - 7 CCs and a BK7 that's about to hit 8yrs old.  I know about the individual revolver utilization thresholds and the muddiness around aggregate utilization percentages, but am wondering if the 3 point drop I just got on EX8 is due to aggregate utilization or aggregate balances.  My reported overall utilization went from 4% ($2635) to 6.2% ($4091) on $66.2k of total CL and my EX8 score dropped 3ptsfrom 703 to 700 with that.  I know the myFICO alerts and the score changes shown aren't necessarily related, but it's the only change that could have effected it and Experian also notified me the same day as myFICO of the changes and score decrease. Trying to figure out if I crossed an aggregate utilization % threshold or an aggregate balance (in raw dollars) threshold.  I tend to think raw dollars initially because when my total CL was lower I never lost points on any FICO 8 score until I crossed over 9% on aggregate utilization %. It's not enough of a drop to matter, but any thoughts?

An aggregate of 5% and a total balance at $3000 have both been suggested as possible thresholds based on past poster data. However, no real justification for picking $3000 vs $2800 or $3200. The testing on total balance thresholds is limited and not at all rigorous.

Did highest % utilization on an individual card change? If yes, what were before/after values? Also, any change in quantity of cards reporting balances?

[Zoostation1]

@Thomas_Thumb No change in number of cards reporting. I stayed at 3/7.  Individual utilization changes were:

Card1:  increase from 6.9% to 7.9%

Card2: increase from 1.6% to 12%

Card3: decrease from 6.8% to 4.8% 

[Thomas_Thumb]

To summarize, your highest utilization on a single card went from 6.9% to 12%. That crosses above 9% which may or may not be important for the individual card metric.

It looks like you have 3 possible influencers. Consider some follow-up testing to isolate the possibilities.

Went on-line a couple days ago to check my AMEX account. It provides an EX Fico 8 score. My score had been tracking at 847-848 for quite a few months. Then 1 update ago score dropped to 837. This last update was 842. 

I know my utilization has increased recently as I don't paydown/off balances before statement close dates. A couple eye surgeries, new glasses, new recliner sofa and insurance premium spiked usage.

After some investigation here is what I found:

EX F8 @848:

- 2 of 5 cards reporting, highest card UT - 1 @ 10%, AG UT @ 2%.

EX F8 @837:

- 5 of 5 cards reporting, highest card UT - 2 @ 13%, AG UT @ 7%.

EX F8 @842:

- 4 of 5 cards reporting, highest card UT - 1 @ 13%, AG UT @ 4%.

I suspect the big drop from 848 to 837 is partially due to an increase in AG UT%. Threshold at 5% or 6%? I think 5% but some sources suggest 6% (including a reference from an EX web site). Likely 100% of cards with balances was a contributing factor.

The big question is why only a 5 point gain 837 => 842 dropping back below 5% AG UT? Sure, 4 of 5 cards are still reporting balances but, EX is somewhat insensitive to cards with balances if under 100% and QTY reporting does not exceed 6.

[Zoostation1]

Haven't done much to try to isolate my changes yet, but pretty sure I can confirm $4000 isn't a raw dollar threshold.  My utilization dropped ever so slightly to get be below at $3993, but no other material changes with 6.0% aggregate and highest card only going from 12% to 11%.  No EX8 score change.

[Zoostation1]

 I don't have any new data regarding that 3pt drop on EX8, but looking at my data again I can come to some conclusions about TU8 for my profile now that I'm at 8 months with no changes to my TU8 score (still 700).

• vs 3/7 reporting makes no difference on TU8.
• 4%-6.7% overall utilization and anything in between makes no difference on my profile.  Individual utilization never went about 14% during this 8 month stretch total reported balances ranged from $2625-$4119 (there were some CLIs during the stretch but seem to have been immaterial

For EQ8, 2/7 vs 3/7 reporting also doesn't matter, but have an oddity at where at 4% aggregate 3/7 with no card at 10% i had 704 and then a 708. No HPs reporting for either.

@Zoostation1 - Threshold points that I've found related to raw dollars of revolving debt have been around $2k, $5k and $10k. Since my total revolving balances rarely go much above $12-13k, I haven't been able to test above that. Around each of those 3 values that I mentioned, I've seen score changes exclusive of aggregate utilization; aggregate utilization would have been in the 1%-4% range in all cases. I'm on a clean/thick/mature scorecard though, so it's not out of the question that your scorecard could see different results.

@Thomas_Thumb - Do you not believe that EX8 is bulletproof to AWB% changes? I've tested it plenty of times and have never lost a single FICO point in moving from AZEO to 100% AWB and back to AZEO, and I know plenty of others that have reported the same thing. We're on the same scorecard, so I'd expect your results to mirror mine.

 I have no open loans and only a few cards. While my file is not thin per se, it is not thick. Since my loan closed my EQ and TU F8 scores have been fluctuating as number of cards reporting balances has changed. I do see minor +/- 1 point changes on EX Fico 8 and EX Fico 9 now of undetermined origin. Never tried to investigate cause.

Pre mortgage closure none of my F8 or F9 scores changed regardless of 

# of accounts or % of cards reporting balances. The buffer played a role. Only mortgage Ficos showed the sensitivity and industry option scores. 

Years ago I compared Fico 04 and Fico 8 reason code lists for all 3 CRAs. The line item for "too many accounts with balances" had the same code number for EQ and TU but was blank for EX, iirc. My links to those lists are dead but, I may have saved a few. I'll see what I can find and possibly post a screen shot.

I just checked my EX F8 and F9 score history over the last year. There were a handful of 1 point changes. Not sure what triggered those because I have no associated reason code history. Most months showed no change. Could the +/- 1 relate to crossing a low level $2k threshold for total balance? 

AMEX reported a -10 point EX F8 change on 9/29 followed by +5 on 10/13 and another +5 on 10/29. WF reported -13 for EX F9 in Oct and then +13 in Nov. I recall purchasing furniture back then and paying some insurance and medical bills. Those EX score changes were definitely due to changes in balance reporting. AG UT remained at or below 4%  most of the time. However, on a 10/17 summary report from Discover my AG UT went to 6% and also would have exceeded $5k on TB.  So, I did cross above a possible 5% AG threshold. The 2 step paydown and EX F8 5 point score rises could be due, in part, to crossing below a $ threshold for total balance. If highest card UT dropping below 9% is a thing, that could have been in play as well. (Side note: TU Fico 8 reported -6 in Oct and then +6 in Nov).

I would need to pull a EX and TU reports to determine monthly aggregate reported balances.

Below are a couple Fico 8 historical score summary tables to go with my prior post commentary. The 1st is EX Fico 8 as provided by American Express. They include actual pull date which is nice. However, no retained info on aggregate utilization or accounts reporting balances. The 2nd table is TU Fico 8 as provided by Discover. Their extracted summary does not show pull date but, recent statements show Dec 17th and Nov 17th for pull dates. On the plus side, the Discover summary does list aggregate utilization.

Comparing the tables suggest a card with a significant balance reported after 9/17 but before 9/29. Then a different card updated with a reduced balance or $0 balance before 10/13. So, the 10/17 TU pull does not capture the peak total balance or peak aggregate utilization which reached 7%.

Influence of high number or % of cards reporting a balance on TU?

 - My experience is EX Fico 8 lacks sensitivity to number or % of cards reporting balances.
