"""Always-On reflected in bills: Currently the side-by-side bills still include the cost of always-on even though it will be retired when the new pricing launches (to be replaced by min idle instances). We’re working on a fix for this. Until then you can comfortably subtract 48 instance hours per day from the estimate. """

Please don't provide a calculator for a new billing system and then ask your customers to manually adjust the output of the calculator. Terrible user experience and in this case it inflates the apparent bill.
