Nominal return on investment

What Is Nominal Return on Investment?

Nominal return on investment refers to the percentage change in the value of an investment over a period, without accounting for the effects of inflation or taxation. It represents the raw, unadjusted growth of an investment and is a key concept within the broader field of investment performance analysis. When evaluating the success of an investment, understanding the nominal return on investment is the initial step before considering factors that impact real purchasing power.

History and Origin

The concept of measuring investment returns in nominal terms has been fundamental to financial accounting and analysis for centuries. As formal markets developed, particularly with the rise of modern corporations and stock exchanges, the need to track the unadjusted growth of capital became apparent. Early forms of investment tracking would naturally focus on the direct increase in monetary value. The distinction between nominal and real returns became more formally recognized and critical with the widespread understanding and measurement of inflation. Economists began to rigorously differentiate between the two, especially during periods of significant price level changes. Academic work, such as that by Huizinga and Campbell, has explored the relationship between inflation, nominal interest rates, and real returns on various assets, highlighting the importance of considering these factors in financial analysis.²⁰, ²¹

Key Takeaways

• Nominal return on investment is the unadjusted percentage gain or loss of an investment.
• It does not account for the impact of inflation or taxes, which reduce purchasing power.
• Nominal return is the initial measure before calculating the real return.
• While useful for understanding raw growth, nominal return does not reflect an investor's true increase in wealth or purchasing power.
• Regulators, such as the U.S. Securities and Exchange Commission (SEC), emphasize transparent reporting of investment performance, including net returns that consider fees and expenses.¹⁸, ¹⁹

Formula and Calculation

The nominal return on investment is calculated using a straightforward formula. It expresses the profit or loss from an investment as a percentage of the initial investment.

The formula for nominal return on investment is:

Where:

• Current Value is the current market value of the investment.
• Initial Investment is the original amount invested.

This calculation provides the raw percentage gain, reflecting the capital appreciation of the asset.

Interpreting the Nominal Return on Investment

Interpreting the nominal return on investment involves understanding that it represents the absolute monetary growth of an investment. A positive nominal return indicates that the investment has increased in dollar value, while a negative nominal return signifies a decrease. For example, a 10% nominal return means that for every $100 invested, the investment is now worth $110. However, this figure alone does not tell the complete story of an investor's financial well-being. To understand the true increase in purchasing power, investors must consider inflation. A high nominal return can still result in a low or even negative real return if inflation is sufficiently high, eroding the value of the monetary gain. Therefore, while a positive nominal return is generally desirable, its full implications are best understood in conjunction with inflation data.

Hypothetical Example

Consider an investor who purchased 100 shares of XYZ Corp. at $50 per share on January 1, 2024, for a total initial investment of $5,000. On January 1, 2025, the shares are trading at $55 per share, making the current value of the investment $5,500.

To calculate the nominal return on investment:

In this example, the nominal return on investment is 10%. This means the investor's money increased by 10% in dollar terms. However, this calculation does not account for factors like trading fees or the prevailing inflation rate over that year.

Practical Applications

Nominal return on investment is widely used across various facets of finance and investing. It forms the basis for reporting investment gains and losses on account statements and in financial news. Investment managers often quote nominal returns to showcase the gross performance of a portfolio or a specific asset. In corporate finance, businesses analyze the nominal return on various projects or capital expenditures to assess their profitability before considering broader economic factors.

For individual investors, understanding nominal return is crucial for basic performance tracking. For instance, when evaluating a mutual fund, the reported historical returns are typically nominal. However, regulatory bodies like the SEC issue investor bulletins to educate the public on understanding performance claims, emphasizing that past performance is not indicative of future results and encouraging investors to consider all factors, including fees and expenses.¹⁶, ¹⁷ Additionally, the nominal federal funds rate, set by the Federal Reserve, influences borrowing costs and investment returns throughout the economy.¹², ¹³, ¹⁴, ¹⁵

Limitations and Criticisms

While straightforward, the nominal return on investment has significant limitations. Its primary critique is its failure to account for inflation, which erodes purchasing power over time. A seemingly positive nominal return can, in reality, be a loss in terms of what an investor can actually buy. For instance, if an investment yields a 5% nominal return, but inflation is 7%, the investor has experienced a real loss of 2% in purchasing power. This discrepancy can mislead investors into believing their wealth is growing when, in fact, it is diminishing.

Furthermore, nominal return does not consider taxes, which are a direct reduction in an investor's take-home profits. The actual return an investor realizes after taxes are applied is known as the after-tax return. The SEC frequently warns investors about performance claims that might not fully disclose all costs and fees, which can significantly impact an investment's true return.¹⁰, ¹¹ Focusing solely on nominal returns without considering these crucial factors can lead to poor financial decisions and an inaccurate assessment of financial growth. Academic research often delves into the complexities of real versus nominal returns, particularly in the context of bond yields and stock market performance, highlighting how inflation can distort perceived gains.⁸, ⁹

Nominal Return vs. Real Return

The key distinction between nominal return and real return lies in their treatment of inflation. Nominal return measures the absolute monetary gain or loss on an investment without any adjustment for changes in the cost of living. It simply reflects the percentage increase or decrease in the dollar value of the investment.

In contrast, real return adjusts the nominal return for inflation, providing a more accurate picture of an investor's true increase or decrease in purchasing power. Real return answers the question of how much more (or less) an investor can buy with their money after accounting for rising prices. For example, if a nominal return is 8% and the inflation rate, as measured by the Consumer Price Index (CPI), is 3%, the real return is approximately 5%.³, ⁴, ⁵, ⁶, ⁷ While nominal return is important for tracking the growth of capital in dollar terms, real return is critical for understanding the preservation and growth of wealth over time.¹, ²

FAQs

What does nominal return on investment tell me?

Nominal return on investment tells you the raw percentage gain or loss your investment has made in monetary terms. It shows how much the dollar value of your investment has increased or decreased over a specific period. This is the unadjusted return, before considering factors like inflation or taxes.

Why is nominal return on investment not enough to assess performance?

Nominal return on investment is not enough because it does not account for inflation. Inflation erodes the purchasing power of money, meaning that even if your investment has a positive nominal return, your ability to buy goods and services might not have increased, or could have even decreased. To understand the true growth of your wealth, you need to consider the inflation rate.

How does inflation affect nominal return?

Inflation reduces the real value of your nominal return. For example, if you earn a 7% nominal return on an investment but inflation is 4%, your actual purchasing power only increased by approximately 3%. In periods of high inflation, a seemingly good nominal return could still result in a loss of real wealth.

Is nominal return always positive?

No, nominal return is not always positive. If the value of your investment decreases, you will experience a negative nominal return, also known as a loss. Investment values can fluctuate due to market conditions, company performance, or other economic factors, leading to both positive and negative nominal returns.

What is the difference between nominal and effective return?

Nominal return is the stated or unadjusted return over a period. Effective return, often called the effective annual rate, takes into account the effect of compounding interest over a year. For example, a nominal interest rate of 6% compounded monthly would have a higher effective annual return than 6% compounded annually, because the interest earned in earlier months also earns interest.
