What is the Inflation Calculator?
The Inflation Calculator shows you how the purchasing power of money changes over time due to inflation. Inflation is the gradual increase in prices across the economy — meaning ₹100 today will buy less than ₹100 five years from now. Understanding inflation is crucial for financial planning, retirement planning, and setting realistic investment goals.
This calculator helps you answer two important questions: (1) How much money will I need in the future to maintain today's standard of living? (2) What is my current ₹X worth in the future after inflation erodes it?
Why Inflation Matters in India
India has historically experienced inflation rates of 4-8% per year. At 6% annual inflation, your money loses half its purchasing power in just 12 years (Rule of 72: 72/6 = 12). This makes it essential for long-term investors to factor inflation into every financial plan — your retirement corpus, your child's education fund, and all major goals need to be inflation-adjusted.
Inflation and Investment
To truly grow wealth, your investment returns must exceed inflation (the "real rate of return"). If FDs offer 7% but inflation is 6%, your real return is just 1%. This is why equity investments (mutual funds, stocks) that historically return 12-15% are favored for long-term goals — they significantly outpace inflation.
How Does the Inflation Calculator Work?
1. Enter Current Amount: The value of money today (e.g., ₹1,00,000).
2. Enter Inflation Rate: The expected annual inflation rate (India's average is around 5-6%).
3. Enter Years: How many years into the future you want to project.
4. View Results: See the future equivalent (what you'd need to maintain purchasing power), purchasing power loss, and what your current amount will be worth in the future.
Formula & Calculation Method
Future Equivalent = P × (1 + r)^n
Where P = current amount, r = annual inflation rate/100, n = years
Purchasing Power Loss = Future Equivalent − P (extra money needed to maintain today's value)
Real Value = P / (1 + r)^n (what current ₹P will buy in n years in today's terms)
Example: ₹1,00,000 today at 6% inflation for 10 years:
Future Equivalent = 1,00,000 × (1.06)^10 = ₹1,79,085
You'll need ₹1,79,085 in 10 years to buy what ₹1,00,000 buys today.
Example Calculation
Example 1 — Child's Education: College fee is ₹10 lakh today. At 8% education inflation for 15 years: Future cost = ₹31.7 lakh. You need to save for ₹31.7 lakh, not ₹10 lakh.
Example 2 — Retirement: Monthly expenses of ₹50,000 today at 5% inflation for 25 years = ₹1,69,317/month needed at retirement.
Example 3 — Purchasing Power: ₹5 lakh at 6% inflation after 12 years: Real value = ₹2.49 lakh. Nearly half the purchasing power is lost!
