Most investors compare returns using numbers printed by banks or investment platforms. A fixed deposit offering 7% or a mutual fund delivering 12% looks attractive at first glance. But these numbers can be misleading because they don’t account for inflation.
Inflation reduces the purchasing power of your money over time. If your investment return does not beat inflation, your wealth is not truly growing.
This guide explains the concept of real returns, how to calculate inflation-adjusted returns, and how to compare investment options like FD, PPF, and SIP properly.
What Is Real Return
Real return is the actual growth in your investment after adjusting for inflation. It shows how much your purchasing power increases rather than just the numerical value of your investment.
For example, if your investment earns 7% but inflation is 6%, your real return is only about 1%. This means your wealth has grown very little in practical terms.
Understanding real return helps make smarter investment decisions.
Why Inflation Matters in Investing
Inflation increases the cost of goods and services over time. As prices rise, the same amount of money buys fewer items in the future.
If investment returns do not exceed inflation, savings lose value in real terms. This is why simply earning interest is not enough — your returns must outpace inflation to build wealth.
Inflation affects long-term goals such as retirement, education, and property purchase significantly.
Real Return Calculation Formula
You can calculate real return using a simple formula:
Real Return = ((1 + Investment Return) ÷ (1 + Inflation Rate)) − 1
This formula adjusts investment growth by removing inflation impact.
For example:
-
Investment return: 8%
-
Inflation rate: 5%
-
Real return ≈ 2.86%
This shows the actual increase in purchasing power.
Simple Method to Estimate Real Return
If you want a quick estimate without calculation, you can subtract inflation from investment return.
For example:
-
Investment return: 10%
-
Inflation: 6%
-
Approximate real return: 4%
This method is simple but less accurate than the full formula.
Comparing FD, PPF, and SIP Using Real Returns
Different investment products offer different inflation-adjusted returns.
Fixed Deposits (FD)
Fixed deposits provide stable and predictable returns but are often close to inflation rates. After tax and inflation adjustment, real returns may be low.
FDs are suitable for safety and short-term goals but may not build long-term wealth significantly.
Public Provident Fund (PPF)
PPF offers government-backed security and tax benefits. Returns are generally higher than fixed deposits and can provide moderate real returns over long periods.
PPF is suitable for long-term, low-risk investors.
Systematic Investment Plans (SIP)
SIPs in equity mutual funds offer higher return potential and better chance of beating inflation over the long term. However, they involve market risk and require longer investment horizon.
SIPs are suitable for long-term wealth creation.
Example Comparison of Real Returns
Consider the following example:
-
FD return: 7%
-
PPF return: 8%
-
SIP return: 12%
-
Inflation rate: 6%
After inflation adjustment:
-
FD real return ≈ 1%
-
PPF real return ≈ 2%
-
SIP real return ≈ 6%
This comparison shows why inflation-adjusted evaluation is important.
Why Many Investors Ignore Real Returns
Many investors focus only on nominal returns because they are easier to understand. Inflation impact is often overlooked, especially during short-term investing.
Common reasons include:
-
Lack of awareness about inflation impact
-
Focus on guaranteed returns
-
Ignoring long-term purchasing power
-
Comparing products without adjustment
Understanding real returns improves financial decisions.
