Level 1 · Module 1 · Money
Inflation & Purchasing Power
Your money can shrink while the number in your account stays the same.
In this lesson
What you'll be able to do
- Define inflation and purchasing power
- Compute a real return
- Understand why cash alone is risky
Think about it
A samosa cost ₹5 in 2005 and ₹20 today. Did samosas get better, or did your rupee get weaker?
Story
Let's picture it
Suppose your grandfather kept ₹1,00,000 in a steel almirah in 2005. Today that note bundle is still ₹1,00,000, but the basket of goods it can buy is roughly a third of what it once bought. He didn't lose a rupee, and yet he lost. That silent loss is inflation.

Real return in one line
Nominal return
What the product advertises, e.g. 7% FD
− Inflation
e.g. 6% CPI
= Real return
≈ 1%, what you actually gained
Plain English
The simple explanation
Inflation is the general rise in prices over time. Purchasing power is how much one rupee can buy, they move in opposite directions.
India measures inflation mainly with CPI (Consumer Price Index), which tracks a basket of everyday goods. The RBI targets 4% with a ±2% band.
The number that matters to you is real return = nominal return − inflation. A 7% fixed deposit during 6% inflation is a 1% gain, before tax.
Real world
Amul milk
A litre of toned milk was about ₹20 in 2010 and roughly ₹54 by the mid-2020s. That is inflation you can taste, and a useful personal price index.
Watch out
Common mistakes
- Comparing returns without subtracting inflation
- Keeping long-term goals fully in cash
- Assuming your personal inflation equals CPI, education and healthcare usually run hotter
Did you know?
At 6% inflation, prices roughly double every 12 years (Rule of 72: 72 ÷ 6 = 12).
Your turn
Mini challenge
Ask a parent what their first salary was and what a movie ticket cost then. Divide. That ratio is your family's real inflation story.

Summary
Inflation quietly reduces what your money can buy. Judge every return after subtracting it.
- Real return = nominal − inflation
- CPI is India's headline inflation measure
- Cash is safe nominally, risky in real terms
