Calculateur de Real Return
Estimate inflation-adjusted real return from nominal return and inflation rate.
Formula and method
This calculator computes Real return directly in your browser without sending data to an external server.
Mathematical formula
- Real return:
((1+nominal ÷ 100) ÷ (1+inflation ÷ 100)-1) × 100
Variables and parameters
- Nominal return (nominal): default value 7 %.
- Inflation (inflation): default value 3 %.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
