Inflation is the rate at which the general price level of goods and services rises over time, eroding the purchasing power of money. In India, inflation is measured primarily by the Consumer Price Index (CPI), which tracks prices of a basket of goods and services. India's average CPI inflation has been approximately 5–6% over the last decade, with food inflation sometimes reaching 8–10% and core inflation (excluding food and energy) staying around 4–5%.
The inflation calculator answers two key questions: (1) What will ₹1 lakh buy in 10 years? — the future value of today's money. (2) What is the real value of ₹1 lakh received 10 years from now? — the purchasing power in today's terms. The formula is straightforward: FV = PV × (1 + r/100)^n, where r is the annual inflation rate and n is the number of years. At 6% inflation, ₹1 lakh today will cost ₹1.79 lakh in 10 years — meaning your money has to nearly double just to maintain purchasing power.
Inflation is the most commonly overlooked factor in financial planning. A retirement corpus that appears sufficient today may be woefully inadequate 20 years later. For example, if you retire with ₹50 lakh at age 60 and live to 80, even at 5% inflation your expenses in year 20 are nearly 2.65× your current expenses. Inflation-adjusted planning — also called 'real return' planning — is essential for long-term goals.

- Parents are estimating the cost of an engineering college that currently costs ₹3 lakh/year, 10 years from now.
- Someone who received a settlement of ₹10 lakh today wants to know its real value if they won't receive it until 5 years from now.
- A financial planner is explaining to a client why their corpus of ₹2 crore will have only ₹75 lakh worth of purchasing power in 20 years at 5% inflation.
- A retiree wants to know how much their monthly pension of ₹30,000 will be able to buy in 15 years.
Tips for best results
- 1For financial goal planning, always inflate your target amount. If your child's college education costs ₹5 lakh today and is 15 years away, plan for ₹12+ lakh at 6% inflation.
- 2Equity investments have historically beaten inflation in India by 6–8% annually (real return). ₹1 lakh in equities for 20 years at 12% nominal / 6% inflation provides a real return of ₹3.21 lakh.
- 3Healthcare inflation in India runs at 10–14% annually — significantly higher than general CPI. Plan your health insurance sum assured to grow by 10% per year to keep pace.
- 4Real estate, gold, and equities are good inflation hedges in the long run. Bank FDs and fixed-income instruments barely keep pace with inflation after tax, especially for those in the 30% bracket.
- 5Use the 'Rule of 70': divide 70 by the inflation rate to find how long it takes for prices to double. At 6% inflation, prices double every 11.7 years.
Frequently asked questions
- Is Konnect2Tools free?
- Yes. These in-browser tools are completely free to use with no account required for core functionality.
- Do my files leave my device?
- Browser document operations run locally, except where the operation uses an external service, such as AI summarisation. Read the processing note before using sensitive inputs.
- Is the Inflation Calculator tool safe to use?
- Local operations process document content on your device. External-service operations may send inputs as described in the processing note. Keep originals and inspect the output.
- What is India's current inflation rate?
- India's CPI inflation has been approximately 4–6% in recent years, though it spiked to 7–8% during 2022–23 due to global commodity price increases. The RBI's inflation target is 4% (+/- 2%). Food inflation tends to be higher and more volatile. For long-term planning, use 5–6% as a conservative inflation assumption.
- What is the difference between inflation and deflation?
- Inflation is a rise in the general price level (money loses value). Deflation is a fall in the general price level (money gains value). India has rarely seen deflation — the last instance was during the Great Depression era. Mild inflation (2–4%) is generally considered healthy for economic growth.
- How does inflation affect my FD returns?
- A bank FD at 7% with 30% tax leaves a post-tax return of 4.9%. If inflation is 6%, the real return is negative at −1.1% — you are actually losing purchasing power. This is why fixed-income investors in high tax brackets need to consider inflation-beating instruments.
- What is the difference between WPI and CPI inflation?
- WPI (Wholesale Price Index) measures prices at the producer or wholesale level. CPI (Consumer Price Index) measures prices at the retail consumer level. CPI is more relevant for individuals and is the primary inflation measure used by the RBI for monetary policy. WPI can sometimes diverge from CPI based on input cost dynamics.
