AAoA and Oldest Account Thresholds

[Anonymous]

What is know about the magic numbers for attained AAoA and Oldest Account thresholds? Where do the score changes occur?

[Anonymous]

When I had my AMEX accts reaged, my oldest acct age and AAoA were affected, and my TU score went up 8 pts.  Specifically for TU, the AAoA didn't change, but the oldest age went above 20 years.

You can see that message here  (scroll down to the highlighted message - I think it's the third one down)

When my credit history aged from 29 to 30 years, my EX score increased from 831 to 842.  I posted my experience here:

I experienced the 5 year oldest account threshold and I know in this bucket there is a major score change between 1 year AAoA and 2 year AAoA. Well I should say I assume its the same bucket

The simple answer is that no one can answer this. The FICO scoring algorithm is a proprietary trade secret, and how AAoA aging affects FICO scoring is not published.  All we have are anecdotal experiences.

Since AAoA and oldest account aging occurs as just one factor in overall credit scoring, it is almost impossible to isolate their affect with any degree of precision.

Y'all feel free to continue speculating and anecdotizing.

Nature is also 'secretive' and 'proprietary' yet scientists use experimental data to try and figure out what's around us.

If the only thing that changes in your credit report is the oldest age when you see a score bump, you can reasonably assume that's what caused the increase.  It's valid 'speculation', until otherwise proven wrong.

For those who haven't been on the forums since the beginning (and I include myself in that number), pretty much everything that we know about FICO scoring now is the result of anecdotizing and speculating.

It's an online version of the scientific method.

So OK, HTSU - got something good to add the rumor mix?

Nope, all we can do is post what we've seen on our own reports, give as much info as possible about our overall credit picture, to allow for bucketing differences, and toss it out there. Then everyone else gets to jump in and tear it to shreds!

That's kinda how it works. FICO isn't going to hand over the keys to the vault. We're pretty lucky that every now and again, we can get Barry to toss us some scraps from the table.

And btw, for those who sometimes discover amazing new "facts" about scoring, etc. on the internet, be advised that pretty much everything we know is from analyzing info posting by everyday people, often with a lot of assumptions, incorrect data, and missing info to confuse the picture. And this includes what you might find posted online with perfect confidence.

Sort of a credit forensics action.
