How the projection works
The calculator compounds the rate once per year. It is useful for budgets and planning scenarios where you choose the inflation assumption.
FormulaFuture cost = current amount × (1 + rate)years
Example: at 3% annual inflation, $1,000 becomes about $1,344 after 10 years.
Historical inflation is different
Comparing two past periods normally uses the ratio between their Consumer Price Index values. This calculator does not download or claim to use live CPI data.
