How inflation is measured in India
CPI, WPI, and what the headline inflation number actually tracks.
The inflation rate reported every month isn’t the price of any one thing rising — it’s a single number built from tracking a large, fixed basket of goods and services over time. That basket’s composition is exactly why the headline figure can feel disconnected from what you personally notice getting more expensive.
CPI is a basket, not a single price
India’s headline retail inflation figure is the Consumer Price Index (CPI), which tracks the changing cost of a fixed basket of goods and services — food, housing, fuel, clothing, health, education, transport, and more — each carrying its own weight in the overall number. Food and beverages carry the single largest weight in that basket, which is one reason food-price swings move the headline figure so noticeably. A separate index, the Wholesale Price Index (WPI), tracks prices at the producer/wholesale level instead of what consumers actually pay, and doesn’t include services at all — it’s a different measure used for different purposes, not an alternative reading of the same thing. Since 2016, the RBI has formally targeted CPI inflation within a 4% ± 2% band as part of its flexible inflation targeting framework, which is why CPI (not WPI) is the number that drives interest rate decisions.
Why your own inflation rate can differ from the headline number
The basket’s weights reflect an average household’s spending pattern, not yours specifically. If your own spending leans heavily toward categories that have historically run hotter than the headline rate — healthcare and education are commonly cited examples in India — your personal cost of living can rise meaningfully faster than the reported CPI figure, even though both are describing the same underlying economy.
What a higher personal rate actually costs you
Using the Inflation Calculator’s own defaults — ₹1,00,000 over 10 years — at a 6% headline CPI rate, you’d need ₹1,79,085in 10 years to match today’s buying power, and today’s ₹1,00,000 would be worth just ₹55,839in today’s terms by then — a 44.2% erosion. At a 9% personal rate (closer to what a healthcare- and education-heavy budget might actually experience), the same exercise needs ₹2,36,736 instead, and erosion rises to 57.8%. That’s ₹57,651more required for the identical purchasing power, purely from assuming the headline rate applied to a budget that didn’t actually track it.
See what today's money will actually be worth years from now.
When projecting a specific future goal — a child’s education, medical costs in retirement — consider using a higher assumed rate for that specific category rather than the headline CPI figure, since those are exactly the categories most likely to have historically run ahead of the average.
