Health plan websites and printed marketing materials provide premium and other cost information. Don’t sign up for a plan without carefully reviewing all the terms of the coverage and comparing all costs: not only the monthly premium, but also deductible and copayment/coinsurance amounts. For example, if you or a dependent have a chronic illness it may be more cost-effective for you select a plan with a higher premium, but a lower deductible. (Then again, you may come out ahead with a lower premium and a higher deductible. There's no single right answer that works for everyone.) If you are buying insurance through the health insurance marketplace/exchange in your state, the marketplace will help you review the available options and compare their costs. An online or in-person broker who is certified by the marketplace can help you make sense of the available options and understand how much you'd pay in both premiums and out-of-pocket medical costs. If you are eligible for Medicare, one helpful resource for comparing options is the Medicare Plan Finder tool, which lets users compare Medicare Advantage, Medigap, and Medicare Part D plans, including expenses and coverage. If you are comparing health plan options through your employer, check with your employer's human resources department. They often can point you to online tools to help you compare the options. These tools help you evaluate the types of healthcare services you might need over the plan year and help you choose the plan that makes the best financial sense for you and any dependent you plan to cover under your policy.
