I don't know if one would change buckets when going from 5 years AAoA to six. If so, there may be a change, although not significant I wouldn't think.
If you have a major derogatory on your report, then certainly not significant.
Contrary to my learned collegues opinions -- I have seen evidence (not anecdotal) from another website that shall remain nameless. A poster there had researched and tested the algorithms to see their outcomes. Indeed, a user will get a decreasing increase to their scores as your AAoA grows. What he found was there the algorithms (which are supposed to secret) produced score bumps at 6mth, 1 yr, 2 yr, 5 yr, 10yr and 15 yr. with the greatest effect upon reaching the first steps. What kind of increase would you get at the 5 year anniversary -- probably only a few points.
No I won't post the link.The last time I did, the post was deleted because unknown to me the website apparently also promotes illegal ways of debt reduction.
Now for the anecdotal story - mine! Equifax recently calculated my AAoA as 5 years. Since I check my score weekly, I can determine with reasonable accuracy what the reason was for the score change. I had one inquiry aged 2 years and so it dropped off at the same time as the aniversary. The score change was 7 points. You're mileage may vary but a score change of few points is not significant.
