Fisher Effect Calculator

Calculate the relationship between nominal rate, real rate, and expected inflation.

Fisher Equation:
(1 + Nominal) = (1 + Real) × (1 + Inflation)
Approximate: Nominal ≈ Real + Inflation
Exact Real = [(1+Nom)/(1+Inf)] − 1

The Fisher Effect

The Fisher Effect, proposed by economist Irving Fisher, states that the real interest rate equals the nominal rate minus expected inflation. In the long run, nominal rates adjust one-for-one with inflation expectations.
