Worth in today’s money—
Enter your assumptions to calculate.
A fixed annual inflation rate; your spending basket may differ.
What this calculation assumes
Assumes the same inflation rate each year. Shows a fixed amount’s purchasing power in today’s dollars and the future amount needed to match today’s spending. Not a CPI forecast.
The formula
Today-equivalent value = amount ÷ (1 + inflation rate)^years. Future amount needed = amount × (1 + inflation rate)^years.
