How do I compare total annual cost instead of just monthly premium?

Monthly premium is the number everyone looks at first, and it's the least useful number on its own. Two plans with the same premium can cost you very different amounts by December 31.A more honest comparison adds up four things. Start with your annual premium, which is just your monthly premium multiplied by twelve. Then add your estimated drug costs, which Medicare's Plan Finder can calculate based on the medications you take. Next, think through your likely copays for doctor visits, specialist appointments, and any procedures you expect. Finally, look at the plan's deductible, which is the amount you pay before coverage kicks in.Add those together and you get something much closer to your actual annual cost.There's also a safety net number worth knowing: the out-of-pocket maximum. That's the most a plan can require you to pay in a year for covered services. It doesn't mean you'll hit it, but knowing the ceiling tells you what your financial risk is if something unexpected happens, like a hospital stay or a new diagnosis.This kind of total-cost comparison takes an extra twenty minutes but can reveal thousands of dollars in difference between plans that look similar at first glance. Plan costs and structures change annually, so recalculate each fall during Open Enrollment rather than assuming last year's math still applies.
