Real Return Calculator

What you see is rarely what you get. Use this calculator to convert a nominal return into a real (inflation-adjusted) return — the only number that matters for long-term wealth. A 7% FD in a 6% inflation world barely moves the needle.

Real return uses the Fisher equation: (1 + nominal) / (1 + inflation) − 1. A 7% FD in a 6% inflation world is barely keeping up — a 12% equity return is what actually builds wealth.

Methodology

How we calculate this

Real return (Fisher equation)
(1 + r_real) = (1 + r_nominal) / (1 + i)

The exact form. The shortcut r_real ≈ r_nominal − i works only for small numbers.

Frequently asked

Is real return the same as nominal − inflation?
Close, but not exactly. The exact formula is (1 + nominal) / (1 + inflation) − 1. Subtraction is a good approximation at low rates.
Why can real return go negative?
When inflation exceeds your investment return, your purchasing power shrinks. Holding cash in a high-inflation period is a silent capital loss.
