Complete Guide to Inflation, Purchasing Power & Future Value
Inflation is the silent destroyer of wealth. As consumer price indices rise year after year, the purchasing power of a fixed rupee or dollar progressively diminishes. Calculating inflation-adjusted future values is mandatory when setting long-term retirement targets, child education funds, and emergency savings.
Future Value Inflation Formula
- Future Cost (FV) = PV × (1 + r)ⁿ
- Future Value of Today's ₹1 = 1 ÷ (1 + r)ⁿ
- Rule of 72 = 72 ÷ Annual Inflation % (Years to Double)
- Real Rate of Return = [(1 + Nominal Return) ÷ (1 + Inflation)] - 1
Category-Specific Inflation Rates
- General CPI (Food/Clothing): ~5.5% - 6.5% per annum.

Frequently Asked Questions (FAQs)
What is the "Rule of 72" in inflation?
The Rule of 72 is a quick mental math shortcut to estimate how many years it takes for prices to double due to compounding inflation. Divide 72 by the annual inflation rate (e.g., 72 ÷ 6% = 12 years; 72 ÷ 8% = 9 years).
Why does keeping cash in a savings bank account lose wealth?
Standard savings bank accounts offer 2.5% to 3.5% interest, while inflation averages 6%. After factoring in income taxes and price rises, your real net return is negative (-3% to -4% per year), meaning your idle cash loses real purchasing power every single year.
Which asset classes beat inflation historically in India?
Historically, diversified Indian Equity Mutual Funds / Nifty 50 Index (12% to 14% CAGR), Physical Gold (9% to 11% CAGR), and prime commercial real estate have consistently outpaced headline CPI inflation over 10+ year holding horizons.
