Understanding how your investments perform after accounting for inflation is crucial for realistic financial planning. This guide compares inflation-adjusted return to its primary alternatives: nominal return, real return, and after-tax return. We’ll explore what each means, their pros and cons, and when to use them.
What is Inflation-Adjusted Return?
Inflation-adjusted return (also known as real return) measures the profit on an investment after removing the effects of inflation. It reflects the true increase in purchasing power.
Formula:
This metric is essential for understanding the authentic growth of your investment over time.
