See how inflation erodes purchasing power over years. Enter amount, rate, and time — get the future value in today's money.
Equivalent value
$381.55
Total inflation
281.55%
Annualized rate
3.09%
Uses approximate US CPI-U annual averages (1914–2024) with linear interpolation between anchor years.
What it does
Adjust historical US dollar amounts for inflation between 1914 and today using CPI-based approximations. Enter an amount, a start year, and an end year — the calculator shows what that money would be worth in today's terms (or any other year), plus the total and annualized inflation rate for the period.
Values are linearly interpolated between anchor years, so results are estimates, not official BLS figures. Still, it's close enough for context: salary comparisons across decades, property value trends, or thinking about long-term savings goals. See also compound interest for the flip side — how investments can outpace inflation over time.
How to use it
- Enter the original dollar amount.
- Pick the start year (year of the original amount).
- Pick the end year (what year to translate it into).
- Review the equivalent value, total inflation, and annualized rate.
