Definition, Calculation, & Factors That Affect It

Investors who ignore inflation may overestimate future investment values, especially when inflation is high. Real returns give a more accurate picture at least, giving investors a sense of whether their holdings are actually increasing in value. The purchasing power of money earned from an investment is directly affected by inflation and so inflation plays a big role in how the nominal rate of return is interpreted. The nominal rate is the raw percentage gain or loss– it is not adjusted by inflation but over time inflation eats away the value of money.

Nominal Rate of Return in Portfolio Analysis

Market participants also react to inflation data, adjusting their strategies based on anticipated changes in nominal rates. For instance, bond investors might demand higher yields on long-term bonds if they expect inflation to rise, leading to an increase in nominal rates. Similarly, mortgage lenders might adjust their rates to reflect changing inflation expectations, impacting the housing market and consumer behavior. For example, if the nominal interest rate offered on a three-year deposit is 4% and the inflation rate over this period is 3%, the investor’s real rate of return is 1%. On the other hand, if the nominal interest rate is 2% in an environment of 3% annual inflation, the investor’s purchasing power erodes by 1% per year.

This formula calculates the total percentage gain or loss on an investment, without adjusting for factors like inflation or taxes. One example of a nominal interest rate is an interest rate quoted at a bank on any given day. If a bank advertises an annual interest rate of 2.59% on a car loan, this is the nominal interest rate. It is the amount of interest a person would pay in a year for borrowing funds to buy a car. Lowering interest rates can boost economic activity and encourage borrowing, while increasing interest rates can slow growth and reduce inflation.

Measuring raw performance is useful however, the nominal rate doesn’t measure an investment’s true value over time.
