How quickly do credit scores change/update?

[SunnyD]

Curious - since factors like debt load and credit line usage literally change daily, I'm wondering how often credit scores get updated.

Every time your credit is run, the formulas take what is currently on your report to get your score.

If something new reported on your credit every day, it could change every day.

Credit scores are not updated, a score is calculated off of a snapshot of your report (which changes daily).

In reality most creditors report only monthly, and they may lag behind by a cycle or two. So if you've made changes and want to see the score impact wait at least a month.
