## Re: Utilization 9% --> 8%; FICO 8 +7

Confirming that the flip from rounded 9% to rounded 8% in aggregate utilization actually affected FICO 8, today the aggregate utilization oscillated back from 8% to 9% .... and 7 points dropped off.

That's very interesting!

In that topic I started, 'Utilization Intervals, Brackets, etc.', @Creditguyindixie posted that he believes all division calculations are rounded up.

This would occur prior to being compared to FICO breakpoints (10%, 30%, etc.). 9.00 stays at 9, 9.01 gets rounded up to 10. In mathematics, it's a ceiling function - ⌈9.00⌉ = 9,  ⌈9.01⌉ = 10.

For your 9% figure,  if your  ((Sum of statement balances)/(Sum of credit limits) * 100 ) > 9.00, that would be 10 inside the FICO algorithm, and hit the 10% threshold, if Creditguyindixie is correct about the rounding method.

It is clear to me that EX is rounding up and down, and that the score moves with the rounded percentage not the actual percentage. It treated 8.95% as 9%, 8.14% as 8%, and today is treating 8.93% as 9%.

This is based on daily realtime observation over a period of about 4 months.

I just randomly visited some of my older EX reports to test this and confirmed:

12.25% = 12%

8.95% = 9%

6.43% = 6%

9.16% = 9%

This observation applies only to EX, and only to aggregate revolving utilization percentages.

So your own calculated aggregate utilization moved from 8.14% to 8.93%, and you lost 7 points. That really shakes up the common wisdom on these forums.

Thanks for starting the topic and posting all that!

What makes it possible is this new EX subscription. It's amazingly informative to have daily reports and FICO scores.

Unfortunately, like the MyFICO monitoring products, it's expensive.

Is that Experian CreditWorks Premium for \$24.99 a month? I have that now after signing up for the \$4.99 first month trial. I was thinking of canceling it after I get updates next week to changes from 0.47% aggregate to 7% aggregate. And 7% individual utilization on each card with 2 cards total. So number of accounts with balances will change from 1 to 2. Not a great report to use for comparison, but next month's at 6/6/6 util will be perfect for that.

I also have the \$39.95 myFICO Ultimate 3B+, and I like it a lot, but ECP updates are definitely more granular than myFICO. I'm mostly interested in TU updates. If TU had an ECP like service I'd probably stick with that exclusively.

Yes that's the one. I find it to be an awesome product. Daily EX report plus 7 EX scores on a daily basis. I especially love that I can compare the mortgage score's behavior to that of FICO 8.

I have that too, certainly the best for completeness, but does not give that 'real time' precision EX is giving me, which frequently enables me to pinpoint the precise reason for a score change.

but ECP updates are definitely more granular than myFICO. I'm mostly interested in TU updates. If TU had an ECP like service I'd probably stick with that exclusively.

For me it works out well because EX is by far the most important bureau for me. And TU's daily service, to which I do subscribe, is junk in my book.

Just an FYI, CWP is \$19.99 a month in the app. Same product at a lower price

The next step is to replicate this actual Aggregate Utilization change, actual percentage not EX display rounded percentage, when that single card utilization is not crossing 10% on its way to a zero value.

Absent that, this score change is caused by individual card utilization, individual card going to zero, not aggregate utilization.
