@IndirajithuRanjith-8274 Thanks for the question and apologies for any confusion between the two pages.
For the pricing details mentioned in the pricing page
Let us assume for a standard tier we have only 1000 no. of transactions for a resource. In this case, according to the above table the charges should be 1$ for transactions and for storage if we have 1000 faces the charge should be 0.01$. So, the total for this resource is $1+$0.01=$1.01
Using the calculator if we use the same numbers it displays the same dollar value.
I think there might be a confusion with the transactions box mentioned in the calculator page as it represents thousands/month to simplify entering the details for large numbers. Also, as the number of transactions increase the price/thousand requests goes down hence the different slabs are mentioned in the pricing page.
We hope this has helped you use both the pages and estimate your costs correctly.
