Worst-case year = 12 × (monthly plan premium − any Part B giveback) + in-network maximum out-of-pocket. The giveback is money back on the Part B premium ($202.90 a month in 2026), which is otherwise the same for everyone, so a large one can push the worst-case year below $0; drug costs are capped separately at $2,400 in 2027. Other extras are the yearly maximums each plan filed with CMS and don’t change the order. Methodology
