Inflation affects planning because a dollar amount that seems sufficient today may buy less in the future.
Inflation compounds
Each year’s increase applies to a higher price level.
The longer the timeline, the more sensitive the result becomes to the inflation assumption.
Use category-specific thinking
A broad inflation average may not match a household’s actual costs.
For important goals, test a higher rate for categories rising faster or representing a large budget share.
Compare growth after inflation
Savings or investments should be evaluated in real purchasing-power terms.
For emergency funds, safety and access matter; for long-term goals, growth potential may matter too.
