Inflation-Adjusted Return Calculator
A 10% return sounds good, but if prices rise 6% a year, you are only about 4% better off. The real return strips inflation out, showing how fast your buying power actually grows.

A 10% return with 6% inflation is a real return of 3.77%. ₹5,00,000.00 grows to ₹12,96,871.23, worth ₹7,24,166.12 in today's money.
Show the calculation steps
- Real return = (1 + nominal) ÷ (1 + inflation) − 1 = 1.1 ÷ 1.06 − 1 = 3.774%.
- Nominal value after 10 years = ₹5,00,000.00 × (1 + nominal)^years = ₹12,96,871.23.
- Value in today's purchasing power = ₹5,00,000.00 × (1 + real)^years = ₹7,24,166.12.
- The exact formula divides (1 + nominal) by (1 + inflation). Simply subtracting inflation from the return is only an approximation.
Nominal versus real
The nominal return is the number you see on a statement. The real return is what remains after inflation and is what determines what you can buy with the money.
Why it matters over time
Inflation compounds too. Over a decade the gap between the nominal and real value can be large, which is why long-term goals should be planned in inflation-adjusted terms.
Formula
Real return = (1 + nominal) ÷ (1 + inflation) − 1
Real value = Amount × (1 + real return)^years
Where:
- nominal
- = Return before inflation, as a decimal
- inflation
- = Inflation rate, as a decimal

Step-by-step
- Real return = (1 + nominal) ÷ (1 + inflation) − 1 = 1.1 ÷ 1.06 − 1 = 3.774%.
- Nominal value after 10 years = ₹5,00,000.00 × (1 + nominal)^years = ₹12,96,871.23.
- Value in today's purchasing power = ₹5,00,000.00 × (1 + real)^years = ₹7,24,166.12.

Frequently asked questions
How do I calculate the real rate of return?
Divide (1 + nominal) by (1 + inflation) and subtract 1. Subtracting inflation from the return is only an approximation.
What inflation rate should I use?
Use a long-run average for your country, or the rate you expect for the goal you are saving for.
Can a real return be negative?
Yes, when inflation is higher than the nominal return, your buying power falls.
