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.
