Fisher Equation
Real return = ((1 + Abstract return/100) / (1 + Inflation rate/100)) - 1 Future value = investment × (1 + nominal abstract return/100)^n Actual purchasing power = investment × (1 + actual return)^n
The importance of real returns.
Investors tend to focus on abstract returns, but real returns tell us how much purchasing power actually increases. Investments that yield less than inflation mean that purchasing power decreases even though the amount of money increases.
Frequently asked questions
What is Real Return?
The real return is the return after deducting the inflation effect. The formula is (1 + nominal return) / (1 + inflation rate) - 1. If the nominal return is 7% and inflation is 3.5%, the real return would be about 3.4%, not 3.5%.
What's the average inflation rate in Thailand?
The average inflation rate in Thailand in the last 10 year was around 1-3% per year, but in some periods of the year 2022-2566 it was as high as 5-7% due to higher energy and food prices. Using the average 3-3.5% is a reasonable estimate.
Why calculate the real return?
Because inflation erodes the purchasing power of money, even if investments yield a return of 5%, if inflation is 3.5%, the purchasing power actually increases only to 1.4%. Knowing the real return helps to accurately compare investment options.
