Inflation-Adjusted Return Calculator
Project nominal investment growth, then express the ending balance and return in today's dollars after an inflation assumption.
Nominal and real ending value
Read the future statement balance beside what that balance may buy in present-day dollars.

Why purchasing power changes the result
The calculator projects contributions at the nominal return, then discounts the ending amount by the entered inflation rate. The real figure expresses the future balance in today's purchasing power.
- Nominal and real results answer different questions.
- Contributions are modeled monthly.
- Taxes, fees and uneven market returns are not included.
Future balance and future buying power are not equal
A goal written in today's dollars needs a real comparison or an inflated future target.

Use nominal and real values for different questions
The nominal balance is the amount that may appear on a future statement under the model. The real balance estimates what that amount could buy in today's dollars.
A goal written in today's prices should be compared with the real result or inflated into future dollars. Mixing a future balance with a present-day target creates a false surplus.
Remember that inflation is not one household number
Food, health, education, housing and transport can change at different rates. A broad inflation assumption is a starting point, while a specific goal may need its own cost-growth estimate.
Run more than one inflation case. A small annual difference compounds over a long period and can materially change the purchasing-power result.
Keep fees, taxes and risk outside the headline return
If the entered return is before fees or tax, the projection overstates money available for the goal. Use an after-fee assumption and review tax treatment for the actual account.
Returns also arrive unevenly. A real-return estimate improves planning language but does not remove market loss, sequence risk or the need to match allocation with the withdrawal date.

Common questions about this calculator
What is the difference between nominal and real value?
Nominal value is the future dollar balance in the model. Real value discounts that amount by inflation to express approximate purchasing power in today's dollars.
Should one inflation rate be used for every goal?
Not automatically. A broad rate is a starting point, while education, health, housing or another specific goal may require its own evidence-based cost scenario.
