Trying to Calculate Retention Rate

Hi, I'm currently trying to calculate retention rate, but I'm currently running into errors since I'm not yet familair with the process.

Currently I have:

Retention Rate =

DIVIDE( Calculate(Count('Table13'[name]), FILTER( 'Table13', 'Table13'[Status]="Recieved"))

-( Calculate(Count('Table13'[name]), FILTER( 'Table13', 'Table13'[Status]="Rejected" AND "Terminated")

,

DIVIDE( Calculate(Count('Table13'[name]), FILTER( 'Table13', 'Table13'[Status]="Recieved"))

)

The Equation is suppose to look like :

Retention Rate = (Total Recieved)-(Rejected+Terminated)/(Total Recieved)
