What ₹1,00,000 of today’s things will cost
₹1,79,085
in 10 years at 6% inflation a year
- Today’s amount₹1,00,000 (56%)
- Extra due to inflation₹79,085 (44%)
- Today’s amount
- ₹1,00,000
- Extra needed
- ₹79,085
- What ₹1,00,000 will buy then (in today’s money)
- ₹55,839
- Future amount needed
- ₹1,79,085
Money kept idle loses 44% of its buying power in 10 years. At 6% inflation, prices double about every 11.9 years — your savings need to grow faster than that.
Impact over time
- Amount needed to buy the same things
- What today’s amount is worth
The gap between the two lines is what inflation takes away.
Complete Guide to Inflation Calculator: Protect Your Wealth
Inflation is the silent killer of wealth. It steadily reduces what your money can buy. A ₹100 note today will not buy the same goods 10 years from now. The Inflation Calculator helps you visualise this erosion and plan your investments to stay ahead of rising prices.
Our interactive Inflation Calculator above shows you the future value needed to match today’s purchasing power, and how much your current money will be worth in the future. You can adjust the inflation rate (historically 5-7% in India) and time period to see the stark reality. Use this knowledge to choose inflation-beating assets like equities, real estate, or gold.
1. The Mathematics of Inflation
Future Value = Present Value × (1 + inflation rate)years
Purchasing Power = Present Value / (1 + inflation rate)years
For example, if you have ₹1,00,000 today and inflation is 6% per year, after 10 years you’ll need ₹1,79,085 to buy the same basket of goods. Conversely, your ₹1,00,000 will have the purchasing power of just ₹55,839 in today’s terms.
2. Why Inflation Matters for Every Indian
- Savings erosion: Bank FDs giving 7% interest might seem good, but if inflation is 6%, your real return is only 1%.
- Retirement planning: A corpus of ₹1 crore today might seem huge, but at 6% inflation, its purchasing power halves in ~12 years.
- Salary growth: If your salary increases 8% annually but inflation is 6%, your real income growth is only 2%.
- Education & healthcare costs: These sectors often see 10-12% inflation, much higher than CPI.
3. Types of Inflation in India
- CPI (Consumer Price Index): Measures retail inflation – most relevant for common people. Current ~5-6%.
- WPI (Wholesale Price Index): Measures wholesale price changes.
- Core inflation: Excludes volatile food and fuel prices.
- Headline inflation: Includes all items.
4. How to Use the Inflation Calculator for Financial Planning
- Retirement goal: If you need ₹50,000 per month today, adjust for inflation to find required monthly amount at retirement.
- Child education: Today’s engineering college fee ₹15 lakhs may become ₹40 lakhs in 10 years at 10% education inflation.
- Investment selection: Compare asset returns after adjusting for inflation (real returns).
- Budgeting: Factor in inflation when planning long-term expenses.
5. Historical Inflation Trends in India (1990-2024)
India has seen wide inflation swings – from double digits in early 1990s (12-14%) to single digits post-2000. The 2010s averaged ~6-7%. Post-COVID, inflation spiked to 6-7% but has moderated to ~5%. Our calculator lets you simulate different scenarios – conservative (4%), moderate (6%), and aggressive (8%).
6. Inflation-Beating Investment Options
- Equity mutual funds: Historically delivered 12-15% returns, beating inflation by a wide margin.
- PPF: Current 7.1% tax-free – real return ~1-2% after inflation.
- Gold: Over long term, gold returns ~8-10%, often beating inflation.
- Real estate: Capital appreciation plus rental income, though illiquid.
- Inflation-indexed bonds: Specifically designed to protect against inflation (NSC, IIB).
7. The Rule of 72 for Inflation
The Rule of 72 tells you how many years it takes for inflation to halve your money’s purchasing power: Years = 72 / inflation rate. At 6% inflation, money loses half its value in 12 years (72/6). At 8% inflation, just 9 years. Use our calculator to see this effect precisely.
