Overview

How the Inflation-Adjusted Return Calculator Works

A 10% return means very different things at 2% inflation vs 8%. This calculator projects both the nominal balance and the real (inflation-adjusted) balance — the purchasing power your future money will actually have in today's dollars.

Formula

The Math Behind the Calculator

Real Rate = (1 + Nominal Rate) / (1 + Inflation Rate) − 1. Real FV = PV × (1 + real)^n + PMT × ((1 + real)^n − 1) / real, using monthly periods.

Example

A Worked Example

$50,000 initial, $500/month, 30 years at 7% nominal return, 3% inflation: nominal FV is about $807,000, real FV is about $332,000 in today's dollars. Nearly $475,000 of that headline number is inflation, not real growth.

How to use

How to Use the Inflation-Adjusted Return Calculator

  1. 1Enter your starting balance and monthly contribution.
  2. 2Enter the expected nominal annual return.
  3. 3Enter expected long-run inflation (2.5–3% is typical for the US).
  4. 4Set the number of years.
Interpretation

What the Results Mean

  • Nominal FV is what your statement will show — the raw dollar amount.
  • Real FV is what those dollars can actually buy in today's terms — the number that matters for retirement planning.
  • Purchasing-power loss is the gap between the two — the amount of headline growth that inflation absorbs.

Common Mistakes to Avoid

  • Planning retirement using nominal numbers and being surprised the money buys less than expected.
  • Using very low inflation assumptions (1%) when the long-run US average is closer to 3%.
  • Comparing bond and stock returns without adjusting for inflation — often changes the ranking.

FAQ

Frequently Asked Questions

What inflation rate should I use?+

US long-run average is 2.5–3%. Use higher for more conservative planning.

Are returns adjusted for taxes?+

No — this is a pre-tax projection. Adjust separately or use a tax-advantaged account model.

How is real return different from nominal?+

Real return strips out inflation, showing the actual growth of purchasing power — the number that matters long-term.
