What is Inflation Calculator?

Calculate how inflation erodes purchasing power in India. Find the value of money over time with historical CPI inflation rates. Productivity tools to help you work smarter and faster. TekPulse's Inflation Calculator is completely free — no signup, no ads in results, and no data stored on our servers.

How to Use Inflation Calculator Online

  1. Enter the original amount (e.g. ₹1,00,000)
  2. Enter the annual inflation rate (India's long-term average is approximately 6%)
  3. Enter the number of years to project forward or backward
  4. View the inflation-adjusted value and the purchasing power loss over time
  5. Use the reverse mode to find what today's amount was worth in a past year

Inflation Calculator Formula & Calculation

Future-equivalent Value = Amount × (1 + Inflation Rate)^Years

This tool projects what a given amount of money from one year would be "worth" (in nominal terms) in another year, by compounding a chosen annual inflation rate over the number of years between them — the same compound-growth formula used for compound interest, applied here to rising prices rather than rising savings.

Purchasing power lost is then derived as the inverse: Retained % = (Original Amount ÷ Inflated Amount) × 100, so a higher inflation projection shows a lower retained percentage, meaning the original amount buys proportionally less by the target year.

Example: ₹1,00,000 in 2010 at an assumed 6% average annual inflation, projected to 2024 (14 years): Adjusted = 1,00,000 × (1.06)¹⁴ ≈ ₹2,26,090 — meaning what cost ₹1 lakh in 2010 would "cost" about ₹2.26 lakh in 2024 nominal terms, and your original ₹1 lakh retains only about 44% of its 2010 purchasing power.

Key Factors That Affect Your Result

  1. Assumed inflation rate — The result is entirely sensitive to the rate you pick; India's actual CPI inflation has varied roughly 3-7% year to year historically, so a single flat assumed rate is only an approximation, not a lookup of real historical CPI data.
  2. Compounding effect over time — Because inflation compounds, small differences in the assumed rate produce large gaps over long periods (e.g., 5% vs 7% over 20 years is the difference between ~2.65x and ~3.87x).
  3. Nominal vs real-value framing — This calculates what a past/future amount is nominally equivalent to, not what your actual investment would have grown to; it's a purchasing-power erosion estimate, not an investment return calculator.

Frequently Asked Questions

Inflation is the rate at which the general price level of goods and services rises over time, reducing purchasing power. If inflation is 6% annually, something that costs ₹100 today will cost ₹106 next year.

India's CPI (Consumer Price Index) inflation has averaged around 5–7% per year over the past decade. The RBI targets a 4% inflation rate (with a 2% tolerance band). Higher inflation periods include 2022–23 when it exceeded 6%.

If your savings earn less than the inflation rate, your real purchasing power decreases. For example, if FD rates are 6.5% and inflation is 6%, your real return is only 0.5%. This is why equity investments targeting higher returns are important for long-term wealth.

CPI (Consumer Price Index) measures the average price change of goods and services purchased by households — this is what affects everyday people. WPI (Wholesale Price Index) tracks prices at the wholesale/producer level. CPI is more relevant for personal financial planning.

Future Value = Present Value × (1 + inflation rate)^years. So ₹1,00,000 today at 6% inflation for 10 years = ₹1,79,085. Conversely, the present value of a future amount = Future / (1 + rate)^years.
