Reaalikorko, often translated as real interest rate, is a fundamental economic concept that measures the true return on an investment or the true cost of borrowing. It represents the nominal interest rate adjusted for inflation. In simpler terms, it tells you how much your purchasing power actually increases or decreases after accounting for the rise in prices over time.

The formula for calculating the real interest rate is: Real Interest Rate = Nominal Interest Rate - Inflation Rate. For example, if a savings account offers a nominal interest rate of 5% and the inflation rate is 3%, the real interest rate is 2%. This means that while your money grew by 5%, its buying power only increased by 2% because prices rose by 3%.

Understanding the real interest rate is crucial for both investors and borrowers. For investors, it indicates the actual profit they are making on their savings or investments. A positive real interest rate means their wealth is growing in real terms, while a negative real interest rate signifies a loss in purchasing power, even if the nominal amount of money has increased. For borrowers, the real interest rate reflects the true cost of their debt. A negative real interest rate can be beneficial for borrowers as they are essentially repaying the loan with money that is worth less in terms of purchasing power.

Central banks often monitor and influence real interest rates as part of their monetary policy to manage inflation and stimulate or cool down economic activity. The distinction between nominal and real interest rates is vital for making informed financial decisions.
