Retirees are often told to plan for 3% to 4% inflation each year. This rule of thumb can be misleading because inflation does not affect all retirement costs equally. In 2026, some costs may be significantly higher than others.
To understand where retirees might feel the most financial pressure, I asked ChatGPT to take a closer look at where retirees are most likely to spend in 2026.
Health care isn’t cheap under the best of circumstances, but retirees may see their health care costs rise significantly this year, ChatGPT said. Medicare Part B premiums and deductibles will rise anywhere from $18 to $26 a month, according to data obtained directly from the Centers for Medicare and Medicaid Services (CMS). Even prescription drug costs can go up, due to inflation-adjusted rates that are unevenly phased. Retirees whose income exceeded the Income-Related Monthly Adjustment Amount (IRMAA) threshold two years ago may see additional charges. Individual filers who report an adjusted gross income between $109,000 and $137,000, for example, will see an IRMAA surcharge of about $81.20, and that number is the most income reported.
Additionally, these are the years of greatest health care use for many retirees, AI noted. Because of the rising nature of these costs, Social Security’s cost-of-living adjustments (COLAs) are often absorbed into health care costs, leaving little buffer for other costs.

Along the same lines, retirees paying for long-term care or at-home help such as home health aides may pay more than usual due to staffing gaps and limited availability at care facilities, AI said. Long-term care costs run well over $100,000 a year, depending on the state, AI reported. While many retirees age in place, finding affordable and reliable care at home can be challenging. The national average hourly rate for an in-home caregiver is $35, AI said, citing data from senior residents. ChatGPT has identified this category as one of the least budget-friendly but fastest-growing retirement expenses.
Home ownership does not directly mean that housing costs are fixed. Even for retirees who own their property outright and don’t have a mortgage, property taxes are rising in some states, AI said. Additionally, homeowners insurance has been steadily increasing over the past few years, especially in climate-prone areas such as Florida or parts of California, ChatGPT said. And retirees who own older homes face increased maintenance and repair costs—tariffs contribute to increased supply and labor costs. Even homeowner association fees may account for increased insurance and infrastructure costs in some areas.
