Real Yield Calculator (Fisher Equation)
Exact real yield from a nominal yield and expected inflation via the Fisher equation — and the error of the simple subtraction.
Formula
At Indian inflation levels the simple nominal-minus-inflation shortcut overstates the real return by 10+ bp; at hyperinflation it fails completely. Real yield is what compounds your purchasing power — the only return that matters over decades.
