WHAT IS THE INFLATION CALCULATOR?
The Inflation Calculator helps you understand how inflation erodes the purchasing power of money over time. Inflation is the general rise in prices of goods and services, which means the same amount of money buys fewer goods each year. In India, the Reserve Bank of India (RBI) targets a CPI (Consumer Price Index) inflation rate of 4% ± 2%.
Understanding inflation is crucial for financial planning. If you keep ₹10 lakh in a savings account earning 4% interest, but inflation is at 6%, your money is actually losing real value at 2% per year. This calculator shows you the future cost of today's expenses and helps you plan investments that outpace inflation.
Inflation particularly impacts retirement planning. What costs ₹50,000/month today may cost ₹1.6 lakhs/month in 20 years at 6% inflation. Planning for this inflation-adjusted expense is essential for a comfortable retirement.

HOW TO USE THIS TOOL
- Enter the initial amount — today's price of something or your current savings amount.
- Enter the annual inflation rate — India's average CPI inflation has been around 5–6% over the past decade. Use 6% as a conservative estimate.
- Enter number of years — how far into the future you want to project.
- Click Calculate — see the future equivalent cost and the real value of your money.
// Formula
THE FORMULA EXPLAINED
Future Value = Present Value × (1 + inflation rate)^years
Real Value = Present Value ÷ (1 + inflation rate)^years
Example: ₹1,00,000 today at 6% inflation for 10 years → Future cost = ₹1,79,085. Your ₹1 lakh today will only have the buying power of ₹55,839 after 10 years.

// FAQ
FREQUENTLY ASKED QUESTIONS
What is India's current inflation rate?
India's CPI inflation fluctuates. The RBI targets 4% inflation with a ±2% band. Long-term planning at 6% is a reasonable conservative estimate. Check RBI's website for the latest CPI figures.
What is the difference between CPI and WPI inflation?
CPI (Consumer Price Index) measures retail inflation — the price change experienced by consumers. WPI (Wholesale Price Index) measures wholesale-level prices. CPI is more relevant for personal financial planning.
Why does inflation reduce money's value?
When prices rise, each rupee buys less. If inflation is 6%, something that costs ₹100 today will cost ₹106 next year — meaning your ₹100 note effectively bought 6% less than it did.
