# FAQs about Calculated Attributes

The following are some of the frequently asked questions about Calculated Attributes:

<AccordionGroup>
  <Accordion title="How many calculated attributes can I create?">
    You can create as many calculated attributes as allowed by the pricing package that you have taken. If you want to create more calculated attributes than allowed by your package, reach out to your Customer Success Manager.
  </Accordion>

  <Accordion title="Where can I use calculated attributes?">
    You can use calculated attributes to define segmentation criteria for your user cohorts in Audiences. You can also use calculated attributes to filter users and events coming through a real-time streaming source.
  </Accordion>

  <Accordion title="How can I see or validate calculated attributes?">
    Currently, calculated attributes are not available in the the Zeotap CDP App UI for a sanity check. However, you can check them by accessing the profile\_store\_scylla and dmgr tables in your GCP bucket.
  </Accordion>

  <Accordion title="How frequently does a calculated attribute get refreshed? ">
    Currently, calculated attributes in the active state are refreshed once, every day. However, note that Paused calculated attributes are not refreshed.
  </Accordion>

  <Accordion title="After a user performs an event, how long does it take for the corresponding calculated attributes to get refreshed?">
    In the above scenario, there are two separate delays resulting in the overall delay.

    * One is the delay in the Zeotap systems that are processing the event performed by the user - this delay is 24 to 48 hours.
    * The other delay is the calculated attribute's refresh delay. Calculated attributes get computed once in every 24 hours.

    Therefore, in the worst case, it may take 48 + 24 = 72 hours for an event to reflect in the calculated attribute values. Usually, it may take between 24 to 36 hours.
  </Accordion>
