Hi b3hdad,
As far as I know, different location of the web app will cause the price of that web app is not same.
I suggest you could firstly check the location of the web app in the Azure calculator to make sure the your portal's web app pricing is as same as the Azure calculator's.
Like below:
From protal:
Notice: This pricing is the estimated value.

From the Azure calculator:

They are almost same.
Best Regards,
Brando
