Every year, the things you buy get more expensive. That's inflation — and understanding it is critical for making smart financial decisions.

## What Is Inflation?

**Inflation** is the rate at which the general level of prices for goods and services rises over time, reducing the purchasing power of money.

If inflation is 6%, something that costs ₹100 today will cost ₹106 next year. Your ₹100 buys less — unless your income or investments grow faster than inflation.

## India's Two Inflation Measures

### CPI (Consumer Price Index)

- **Published by:** National Statistical Office (NSO)
- **Frequency:** Monthly
- **Base Year:** 2012
- **Measures:** Price changes experienced by consumers at the retail level
- **RBI's target:** 4% ±2% (i.e., 2-6% band)

CPI is the **primary inflation measure** used by RBI for monetary policy decisions.

### CPI Basket Composition

| Category | Weight in CPI |
|----------|--------------|
| Food & Beverages | 45.86% |
| Housing | 10.07% |
| Fuel & Light | 6.84% |
| Clothing & Footwear | 6.53% |
| Transport & Communication | 8.59% |
| Health | 5.89% |
| Education | 4.46% |
| Others | 11.76% |

**Key insight:** Food alone makes up nearly half the CPI basket. This is why vegetable price spikes (tomatoes, onions) can push headline inflation up sharply.

### WPI (Wholesale Price Index)

- **Published by:** Office of Economic Adviser, Ministry of Commerce
- **Frequency:** Monthly
- **Base Year:** 2011-12
- **Measures:** Price changes at the wholesale/producer level

### CPI vs WPI

| Feature | CPI | WPI |
|---------|-----|-----|
| Perspective | Consumer (retail) | Producer (wholesale) |
| Services included | Yes | No (only goods) |
| Food weight | ~46% | ~24% |
| Used for | RBI policy, dearness allowance | Industrial monitoring |
| Impact on you | Direct | Indirect (feeds into CPI later) |

## What Causes Inflation?

### Demand-Pull Inflation
Too much money chasing too few goods:
- Rising incomes and consumption
- Government stimulus spending
- Excess liquidity in the system

### Cost-Push Inflation
Rising input costs pushing prices up:
- **Crude oil prices** — India imports 85% of its crude; higher oil = higher transportation and production costs
- **Food supply shocks** — Poor monsoon, crop failure, global food price spikes
- **Rupee depreciation** — Makes imports more expensive

### Structural Factors Specific to India
- **Inefficient supply chains** — Farm-to-fork losses of 20-30% for perishables
- **Agricultural dependency on monsoon** — One bad monsoon can spike food inflation
- **Import dependency for energy** — Crude oil and natural gas prices affect everything

## The Rule of 72: Inflation's Hidden Tax

**72 ÷ Inflation Rate = Years for prices to double**

| Inflation Rate | Prices Double In |
|---------------|-----------------|
| 4% | 18 years |
| 6% | 12 years |
| 8% | 9 years |
| 10% | 7.2 years |

At 6% inflation, something that costs ₹1 lakh today will cost ₹2 lakh in 12 years. Your investments must beat this rate just to maintain purchasing power.

## Real Returns = Nominal Returns - Inflation

This is the most important formula in personal finance:

| Investment | Nominal Return | After 6% Inflation | Real Return |
|-----------|---------------|-------------------|-------------|
| Savings Account | 3.5% | -2.5% | **Losing money** |
| FD | 7.0% | +1.0% | **Barely positive** |
| PPF | 7.1% | +1.1% | **Modest** |
| Equity (long-term) | 12-15% | +6-9% | **Wealth creation** |

## How to Protect Your Money from Inflation

1. **Invest in equity** — Stocks have historically outpaced inflation over 10+ year periods
2. **Avoid excess cash** — Money in savings accounts loses value every year
3. **Consider inflation-indexed bonds** — RBI issues these periodically
4. **Real estate** — Property values tend to rise with or above inflation (but illiquid)
5. **Gold** — Traditional inflation hedge, especially during currency weakness
6. **Increase your income** — Negotiate salary hikes that at least match inflation (6-8%)
7. **Review FD rates annually** — Lock in when rates are high, but ensure they beat inflation

## How to Track Inflation

- **CPI data:** Released by NSO around the 12th of each month (for the previous month)
- **WPI data:** Released by the Ministry of Commerce around the 14th
- **RBI MPC statements:** Discuss inflation outlook and projections
