How does the Inflation Calculator work?

Inflation represents the steady erosion of money's purchasing power over time, meaning more money is needed to purchase the exact same basket of goods and services.

The Reserve Bank of India (RBI) operates under an inflation target band of 4% (+/- 2%), with the official headline measure tracked by the Consumer Price Index (CPI-Combined) published by MOSPI.

Future Value Projection Formula: Future Expense = Present Cost x (1 + Inflation Rate / 100)^Years.

Rule of 72: Divide 72 by the annual inflation rate to find approximately how many years it takes for your money's purchasing power to be halved (e.g., at 6% inflation, purchasing power halves in 12 years).

Income tax capital gains use the Cost Inflation Index (CII) notified annually by the CBDT to index the acquisition cost of qualifying assets.

Inflation Calculator formula

Future Cost = Present Cost x (1 + r/100)^t; Purchasing Power Loss % = ((Future - Present) / Future) x 100

Present Cost
= Current monthly or annual expenditure in rupees
r
= Expected annual inflation rate (historical Indian CPI average: 5% to 7%)
t
= Time horizon in years

Lifestyle inflation in healthcare and education often runs at 8% to 10% in urban India.

Inflation Calculator: frequently asked questions

What is the long-term average inflation rate in India?
Over the past two decades, India's Consumer Price Index (CPI) inflation has averaged between 5% and 6.5% annually. The Reserve Bank of India has a formal target of 4.0% with a tolerance band of 2% to 6%.
How much will ₹1,00,000 today be worth in 10 years at 6% inflation?
At 6% annual inflation, you will need ₹1,79,085 in 10 years to purchase what ₹1,00,000 buys today. Your purchasing power will drop by about 44.2%.
What is the Rule of 72 in inflation?
The Rule of 72 estimates how quickly prices double (or purchasing power halves). Divide 72 by the annual inflation rate. At 6% inflation, 72 / 6 = 12 years to halve purchasing power.
What is the Cost Inflation Index (CII) in India?
The Cost Inflation Index (CII) is a benchmark notified each year by the Central Board of Direct Taxes (CBDT) under Section 48 of the Income-tax Act to adjust the purchase price of long-term capital assets for inflation.
Why is education and healthcare inflation higher than general CPI?
General CPI is heavily weighted towards food and beverages (approx. 45%). Services like higher education and private healthcare experience higher wage growth and capital expenditure, leading to 8% to 12% inflation annually.
Which investments beat inflation in India?
Historically, diversified equity mutual funds (11% to 14% CAGR) and physical gold (8% to 10% CAGR) have beaten inflation over 10+ year periods. Fixed deposits (6.5% to 7.5%) often match or lag inflation after accounting for taxes.
