Formula:

The Fisher Equation Formula

(1 + i) = (1 + r)(1 + π)

  • i = Nominal Interest Rate (the stated interest rate before inflation)
  • r = Real Interest Rate (the interest rate adjusted for inflation)
  • π = Inflation Rate (the rate at which prices increase)

This formula precisely relates nominal interest rates to real interest rates and inflation, revealing the true purchasing power of returns.
