Inflation-Adjusted Return Tool

A 10% return sounds great — until you realize inflation ate 3% of it. Your real return is closer to 6.8%, and over 20 years that difference compounds into a massive gap. Understanding the difference between nominal and real returns is essential for setting realistic retirement goals and evaluating investment performance honestly.

Enter your nominal return, the inflation rate, your investment amount, and time horizon. See exactly how much purchasing power you gain versus how much inflation takes.

The Math: Fisher Equation

Real Return = (1 + Nominal Return) / (1 + Inflation Rate) - 1

The common shortcut (nominal minus inflation) works as an approximation but understates the real return slightly. The Fisher equation gives the exact figure.

Why This Matters

• Retirement planning: If your target is $1M in future dollars, you need much more in today's purchasing power. A 3% inflation rate over 30 years means $1M buys what $412K buys today.
• Comparing across eras: Stock returns in the 1970s looked decent nominally but were terrible after accounting for double-digit inflation. The 2010s looked modest but delivered strong real returns.
• Bond evaluation: A 5% bond yield with 4% inflation gives you only 1% real return. Bonds can lose purchasing power even when they pay positive nominal interest.

Protect Your Purchasing Power

• Screen for high-growth stocks — companies growing faster than inflation protect your real returns.
• Or find dividend growers with pricing power — businesses that can raise prices (and dividends) with inflation.
