How to calculate the quality point deficit?

I’m kinda puzzled about how to calculate the quality point deficit. According to the UB website, it’s calculated by taking (GPA hours x 2) - (Cumulative quality points). I’m not sure how cumulative quality points are figured out. Is it the GPA point scale multiplied by the credits? Or is it just the cumulative points on the scale? Does it include only the credits I’ve completed, or all credits? I’m really confused and could use some help.

Not sure how it is calculated. But would like you to connect with the Academic Advisor. He/She will be the best person who can guide you through it.
Thank You !!
