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 5% a year, something that costs ₹100 today will cost about ₹105 next year.
What inflation is
A little inflation is normal in a growing economy. The problem is when it is too high, eroding savings and making planning hard, or when prices fall persistently, called deflation, which can discourage spending and investment. Central banks aim to keep inflation low and stable.
How it works in India
India's main measure is the Consumer Price Index (CPI), published monthly by the National Statistics Office, which tracks prices of a basket of goods and services bought by households, including food, fuel, housing and services. The Wholesale Price Index (WPI) tracks prices at the wholesale level.
The Reserve Bank of India (RBI) follows a flexible inflation targeting framework, with a CPI inflation target of 4%, within a band of 2% to 6%. Its Monetary Policy Committee sets the repo rate, the key interest rate. Raising rates tends to cool inflation by making borrowing costlier; cutting rates supports growth when inflation is under control.
Causes of inflation
Demand-pull inflation happens when demand exceeds what the economy can supply. Cost-push inflation happens when costs rise, for example fuel, raw materials or wages, and businesses pass them on. In India, food prices, affected by monsoons and supply conditions, often have a large influence on inflation.
A simple example
You keep ₹1,00,000 in a savings account earning 3% while inflation is 5%. After a year you have ₹1,03,000, but goods that cost ₹1,00,000 now cost ₹1,05,000. Your money has lost about 2% of its purchasing power. Your real return, return minus inflation, is negative.
Why it matters for investors
Inflation erodes savings held in cash or low-yield deposits, influences interest rates and therefore bond prices, and affects company profits: firms with pricing power can pass on higher costs, while others see margins squeezed. Over long periods, investments such as shares have historically offered a better chance of beating inflation than cash, though with more risk.
Inflation and your financial plan
When planning for long-term goals, include inflation. A goal that costs ₹10 lakh today could cost about ₹18 lakh in 12 years at 5% inflation. Planning with today's prices can leave you well short of what you need.
Inflation and different investments
Different assets respond differently to inflation. Cash and fixed deposits can lose purchasing power when rates lag inflation. Bonds with fixed coupons lose value when inflation and rates rise. Shares of companies with pricing power can grow earnings over time, offering potential protection. Gold has historically been seen as a hedge during high inflation, though its returns vary. A diversified mix helps manage inflation risk.
Common misconceptions
"Inflation affects everyone equally." It depends on what you buy; your personal inflation can differ from CPI.
"Deposits are always safe." They can lose to inflation in real terms.
"Zero inflation is ideal." Most central banks prefer low, positive inflation.

Summary
Inflation is the rise in general prices that reduces money's purchasing power. India measures it mainly through CPI, and the RBI targets 4% within a 2% to 6% band, using the repo rate. Inflation erodes cash savings, shapes interest rates and affects company margins, so long-term plans and returns should always be judged in real terms.
