How are the read numbers calculated as a result of function calls?

I have 5000 item in a collection.
I wrote a function to calculate the total sum and count of the item in this collection.
The function using the index as you know to get data and pagination size is 100k.

I want to know Fauna how to calculate the reading count of using this function.
Per call will calculate as one?
Can you explain please?

The only cost is to get a single Page of data from and Index. The rest is compute time.
