Real Cost
Work out the real cost after inflation adjustments.
About Real Cost
The real cost is what a nominal amount is worth later, after inflation compounds it upward. Planning with real rather than nominal figures avoids underestimating future costs when inflation is significant.
Formula
Real Cost
Real cost = nominal x (1 + inflation)^years
- growth factor
- Compounded price growth over the period
Worked example
With the default values below, Real Cost returns Real Cost 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 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.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
