Inflation Adjustment
Adjust a current amount for inflation to a future value.
About Inflation Adjustment
Inflation compounds, so a current amount needs multiplying by a growth factor to keep the same purchasing power in the future. Value erosion measures the share of spending power lost to that inflation. Failing to inflate future costs means routinely underestimating how much money will be needed later.
Formula
Inflation Adjustment
Future = amount x (1 + inflation)^years
- multiplier
- compounded price growth over the period
Worked example
With the default values below, Inflation Adjustment returns Future Amount of $1,343.92. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take tax or fees or charges into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.
