Inflation-Adjusted Return: What It Is and How to Calculate It

An inflation-adjusted return, also called the real return, is your investment return after removing the effect of inflation. It tells you how much your buying power actually grew, not just how much your balance grew.

Which of the Following Is an Inflation-Adjusted Return?

If you came here from a quiz question, the answer is: the real rate of return. The nominal return is the number you see on your statement. The real return is the nominal return minus the effect of inflation.

The Inflation-Adjusted Return Formula

Real return = ((1 + nominal return) ÷ (1 + inflation rate)) − 1

This is the exact formula, known as the Fisher equation. A quick shortcut is nominal return minus inflation, which is close when the numbers are small.

Example 1: 10% Return, 6% Inflation

1. 1.10 ÷ 1.06 = 1.0377
2. 1.0377 − 1 = 0.0377

Real return = 3.77%. The shortcut (10% − 6%) gives 4%, which is close but not exact.

Example 2: When Inflation Beats Your Return

You earn 5% on a savings account, and inflation is 7%.

1. 1.05 ÷ 1.07 = 0.9813
2. 0.9813 − 1 = −0.0187

Real return = −1.87%. Your balance grew, but you can buy less than before.

Example 3: What It Means in Money Terms

You invest 10,000 and earn 8% for one year, so you have 10,800. With 5% inflation, that 10,800 has the buying power of about 10,286 in today's money (10,800 ÷ 1.05). Your real gain is about 286, not 800.

Real Return Over Many Years

For long periods, calculate the CAGR of your investment first with our CAGR calculator, then adjust it with the same formula using the average yearly inflation rate.

Why It Matters

• It shows whether your savings are really growing.
• It helps you compare a fixed deposit, a mutual fund and a stock fairly.
• It helps you set realistic goals, such as retirement or education savings.

Common Mistakes

• Comparing a nominal return to a real target
• Using the wrong inflation rate (use the one for your own country)
• Forgetting that tax also reduces your return
• Using the shortcut for large numbers, where it becomes less accurate
