What Are the Biggest Expenses in Retirement? (2026 Guide)
What are the biggest expenses in retirement in Australia? For homeowner retirees, the four largest budget categories in 2026 are housing costs (even without a mortgage), healthcare and out-of-pocket medical, food and groceries, and utilities. For renters, housing jumps to the top by a wide margin. And through the whole retirement, retirees face higher effective inflation than the general population, because the categories they spend most on have risen fastest.
This guide breaks down where retirement money actually goes using ASFA’s December 2025 quarter budget data, how those costs shift through the different phases of retirement, and the specific expense patterns that catch most Australians off guard.
