A key term when reviewing and comparing the different Part D plans is the Estimated Annual Drug Costs: This number is the sum of the annual premium costs (+) out of pocket drug costs. The plan with the lowest Estimated Annual Drug Costs is the one that should cost the least amount overall, plan and drug costs included.
In the screenshot below You can see the monthly premium is $16.20, which would equate to $194.40 in annual premium payments. This means the annual drug costs in this example would be $154.60 ($349.00 total cost less the $194.40 in premium costs), for a total expected annual outlay of $349.
