Inflation
Inflation
Definition
Inflation is the gradual increase in prices over time, which reduces the purchasing power of money.
Why This Matters
Inflation changes what your money can actually do, not just what it is worth on paper.
Even modest inflation compounds over time. What feels like a manageable cost today can become a significantly larger expense over a long retirement. This is especially important for early retirees because they intend to live off their assets for an extended retirement.
For retirees, inflation directly impacts sustainability. Fixed or semi-fixed income sources may not fully adjust with rising costs, which means a greater portion of spending must come from the portfolio. Over time, this increases pressure on investments and raises the risk of running out of money if growth does not keep pace.
Inflation also does not affect all expenses equally. Certain categories, such as healthcare, tend to increase at a faster rate than general inflation, while others may rise more slowly. This uneven impact can make planning more complex than applying a single inflation assumption.
One Common Misconception
“Inflation is only a concern when it is unusually high.”
Inflation does not need to be extreme to have a meaningful impact.
A steady, moderate inflation rate can significantly reduce purchasing power over time. Over a 20 to 30 year retirement, even small annual increases can compound into much higher costs. Planning that ignores inflation often overestimates how far income and assets will actually go.
Planning Considerations
Retirement spending should be expected to increase over time
Guaranteed income sources may not fully adjust for inflation
Portfolios typically need some growth exposure to offset long-term inflation
Healthcare costs have historically grown faster than average inflation, while discretionary spending may grow more slowly
Managing inflation risk requires balancing growth, stability, and flexibility
