- The equation states that the real interest rate (), is equal to the nominal interest rate () minus the expected inflation rate (). The equation is an approximation; however, the difference with the correct value is small as long as the interest rate and the inflation rate is low.

The Fisher equation is expressed through the following formula: (1 + i) = (1 + r) (1 + π) Where: i – the nominal interest rate. r – the real interest rate. π – the inflation rate. However, one can also use the approximate version of the previous formula: i ≈ r + π. Fisher Equation Example. Suppose Sam owns an investment portfolio.
In financial mathematics and economics, the Fisher equation expresses the relationship between nominal interest rates, real interest rates, and inflation. Named after Irving Fisher, an American economist, it can be expressed as real interest rate ≈ nominal interest rate − inflation rate.

Interpreted in this way, the Fisher equation implies that the sum of two F t+1-measurable random variables is F t-measurable, which at first seems puzzling. But the Fisher equation is actually an accounting identity that defines the ex post real rate r t+1. The forces that really determine the nominal interest rate i t are the expected real rate

The Fisher equation provides the link between nominal and real interest rates. To convert from nominal interest rates to real interest rates, we use the following formula: \[real\ interest\ rate ≈ nominal\ interest\ rate − inflation\ rate.\]
Feb 28, 2024 · The basic equation for the quantity theory is called The Fisher Equation because it was developed by American economist Irving Fisher. In its simplest form, it looks like this:
The equation states that the real interest rate (), is equal to the nominal interest rate minus the expected inflation rate (). The equation is an approximation; however, the difference with the correct value is small as long as the interest rate and the inflation rate is low.
