About This Inflation Calculator – How We Calculate Your Money’s Value
Inflation quietly reduces the purchasing power of your money. That ₹100 note from a few years ago no longer buys the same goods today. Our India Inflation Calculator helps you see exactly how much you need today to match the value of an amount from any year between 2015 and 2026. All calculations follow the official Consumer Price Index (CPI) published by the Ministry of Statistics and Programme Implementation (MOSPI) and are cross‑checked with the Reserve Bank of India (RBI).
Where the Data Comes From
This calculator uses the CPI Combined (Rural+Urban) with base 2015=100. The index numbers from 2015 to 2024 are derived from the annual CPI inflation rates released by MOSPI and the RBI Handbook of Statistics. For 2025 and 2026, we use the RBI’s monetary policy projection of 4.5% inflation (the midpoint of the 2‑6% target band). Every state‑wise index is adjusted proportionally from the national series using regional CPI differentials obtained from official state‑level data.
How the Calculation Works
The equivalent amount is computed using the standard inflation formula:
Equivalent Amount = Original Amount × (CPIend ÷ CPIstart)
Total inflation rate = (CPIend ÷ CPIstart − 1) × 100%.
Annual average inflation is calculated as the compound annual growth rate (CAGR) over the selected period. Purchasing power is simply the ratio of the original amount to the equivalent value.
Why This Calculator is Different
Unlike generic tools that use average national figures, this calculator lets you choose from eight major Indian states, each with its own CPI series. We also show real‑life price changes — rent, petrol, movie tickets, groceries — so you can feel the impact. The results are accompanied by a detailed breakdown: total inflation, annual average, monthly rate, value lost, and remaining purchasing power.
Inflation Calculators for Other Countries
Comparing purchasing power across countries? These use the same CPI-based methodology, built on each country’s own official statistics office.

India Inflation Calculator: What Your Money From 2015 Is Worth Today
If you’re wondering why ₹1,000 doesn’t buy what it used to, or you’re trying to work out a realistic future value for a goal, the India inflation calculator above converts any amount into today’s rupees using India’s official Consumer Price Index — not a rough guess. Enter an amount, pick a year, and optionally a state, and you’ll see the equivalent value, the purchasing power lost, and a few real-world comparisons to make the number concrete.
This page explains exactly where the numbers come from, what the CPI actually measures, and where the tool’s estimates stop being historical fact and start being a projection — because conflating the two is one of the most common mistakes in calculators like this.
What the Consumer Price Index Actually Measures
The CPI tracks the changing cost of a fixed basket of goods and services — food, housing, fuel, healthcare, education — that a typical household buys. When the index rises, the same basket costs more, which means a rupee buys less than it used to.
One correction worth making up front, because a lot of calculators get this wrong: India’s official CPI (Combined) currently runs on a 2012=100 base year, not 2015. MOSPI has proposed rebasing the series to 2024, but as of now 2012 remains the official reference point. This tool uses 2015 as its own starting year for convenience — simply because that’s a clean, recent point most people can relate an old salary or price to — not because 2015 is the government’s base year. If you’ve read elsewhere that the CPI base year is 2015, that’s incorrect; check MOSPI’s own CPI page to confirm the current base year yourself.
Why State-Level Numbers Matter
A national average inflation figure hides real differences between states — food and fuel weightings, local supply conditions, and housing costs all vary. MOSPI publishes state-wise CPI alongside the all-India combined figure, and this calculator uses those state indices rather than applying one flat national number to everyone, which is what most simpler inflation calculators do. If your state isn’t in the list yet, the all-India average is used as the closest available estimate — treat it as an approximation for that state, not a locally-measured figure.
How the Calculation Works
The core formula is straightforward:
From that, the calculator also derives the total inflation rate over the period, the compound annual growth rate (the “annual average” you see in the results), and how much of the original amount’s purchasing power has eroded. For the current year, where the final CPI figure isn’t published yet, the tool uses a projection based on the Reserve Bank of India’s inflation target of 4% (within its 2–6% band) — and that figure is labelled as a projection in the results, not presented as measured data.
Who This Calculator Actually Helps
- Salary negotiations: check whether a raise has kept pace with inflation, or model what an old offer would be worth if made today. Pair it with a take-home salary calculator to see the net effect.
- Retirement and goal planning: a retirement corpus target set five years ago in today’s rupees is already understated — this tool shows by how much. If you’re building that corpus through SIPs, our SIP calculator can model the investment side alongside this inflation figure.
- Real returns on investments: a lump-sum or SWP projection that ignores inflation overstates what your money will actually buy later. Run the nominal numbers in our lump-sum calculator or SWP calculator, then use this page to see the real, inflation-adjusted figure.
- Relocating between cities or states: comparing a salary offer in one state against your current cost of living in another.
Frequently Asked Questions
What is the Consumer Price Index (CPI)?
CPI measures the average change over time in the prices paid for a fixed basket of consumer goods and services — food, housing, transport, healthcare and more. In India, MOSPI publishes it monthly on a 2012=100 base year for Rural, Urban, and Combined indices.
How is inflation calculated from the CPI?
Inflation rate = (CPI at the end of the period − CPI at the start) ÷ CPI at the start × 100. For a multi-year period, the calculator also works out the compound annual growth rate so you can see the average yearly pace, not just the total change.
What is the CPI base year in India — 2012 or 2015?
The official base year is currently 2012=100. MOSPI has proposed moving to a 2024 base year as part of a wider CPI methodology revision, but that change hadn’t taken effect as of this page’s last review. This calculator’s own “2015” starting point is just the earliest year it holds data for — not the CPI’s technical base year.
Why does inflation differ by state?
Consumption patterns, local housing costs, and fuel and food price movements vary by state, so MOSPI publishes separate state-level CPI series alongside the all-India combined figure. A single national average can overstate or understate what’s actually happened to prices where you live.
How reliable is the current-year inflation figure?
Any value for the current year, before MOSPI has published final data, is necessarily a projection — this tool uses the RBI’s inflation target band as its basis and labels it clearly as an estimate. Treat it as a planning assumption, not a historical fact.
Sources and Methodology
Historical CPI figures come from MOSPI’s Consumer Price Index releases and the Reserve Bank of India’s Handbook of Statistics on the Indian Economy. State-level figures use MOSPI’s published state/UT CPI series. The current year’s figure is a projection based on the RBI’s inflation target and is marked as such in the results. Raw datasets are also available on the Open Government Data Platform India if you want to check the underlying numbers yourself.
