Hello Sreeparna,
First of all Welcome to QuickSight Community.
there are two approach on Pricing in in Quikcisght
- User-based pricing
- Capacity pricing
Yes - For Author its $24 /m irrespective of any of pricing model, $50/m for Pro Author
Readers
For User based pricing
its $3/m for Reader
Capacity pricing - Reader
its session based - you are not charged $3/m but instead your QuickSight account are allotted session.
example: for $250 /m you get 500 sessions/m. a session is a 30 minutes period.
these sessions are consumed by your readers (shared among readers) and it gets subtracted from your allotted sessions. once the 500 sessions is exhausted, you need to purchase additional sessions. exhausting session does not mean user will not be able to access the dashboard but you will be charged based on Additional session charge as shown in your screenshot.
Please see here for more details.
NOTE: you cannot have both pricing model, either user-based or Capacity pricing.
Hope this helps.
Cheers,
Deep
