Assumptions & method
- Real value = nominal value ÷ (1 + inflation)years. Real annual return = (1 + nominal) ÷ (1 + inflation) − 1 (the exact Fisher equation).
- Both rates must use the same period (annual here) and compound once a year. If your rates are monthly or quarterly, convert them to annual first.
- No further deposits or withdrawals, and no taxes or fees. Returns and inflation are held constant every year, which real markets will not do.
- The "simple approximation" (nominal − inflation) is shown only for comparison. It overstates the real return when rates are high.

Year-wise Nominal vs Real Value
What are inflation-adjusted returns?
A nominal return tells you how many more rupees you hold. An inflation-adjusted (real) return tells you how much more you can actually buy. When prices rise, each unit of currency buys less, so part of your nominal gain only keeps pace with the cost of living.
The exact relationship is the Fisher equation: (1 + real) = (1 + nominal) ÷ (1 + inflation). This calculator applies it to your investment, then deflates the final value by cumulative inflation to express it in today’s money.
