Inflation Calculator

Inflation is the gradual rise in the price of goods and services. It quietly shrinks what your money can buy — the same ₹1,000 buys less every year. India tracks inflation through the Consumer Price Index (CPI), a weighted basket of everyday items (food, housing, transport, fuel, health and more) measured month to month. Because food is a heavy component of India's basket, headline CPI here can swing more than in most economies when vegetables or edible oils spike — a reminder that the "headline" number is an average, not your personal bill.

The formula

Future value = amount × (1 + rate)^years

With ₹1,00,000 at an average 6% inflation over 6 years (2020 → 2026):

Future value = 1,00,000 × (1.06)^6 ≈ ₹1,41,852

That means a basket of goods costing ₹1,00,000 in 2020 costs about ₹1,41,852 in 2026. Your money's purchasing power did not grow — prices did. Equally useful is the amount in reverse: ₹1,00,000 in 2026 is worth only about ₹70,500 in 2020 rupees, which is what "₹1 lakh won't be worth a lakh in a decade" really means.

Reading the result

• Future value — the nominal amount you would need later to buy the same things.
• Price multiplier — how many times prices grew (here 1.42×).
• Real loss — the "extra" amount (₹41,852) is not extra value, it is the erosion of purchasing power.

Why inflation matters

• Savings — if your FD pays 6% while inflation is 6%, your real return is zero. Real return ≈ nominal interest − inflation.
• Salary — a 5% raise in a 6% inflation year is a real pay cut.
• Long-term planning — retirement and education costs must be inflation-adjusted. A ₹50,000-a-month retirement lifestyle at 6% inflation needs about ₹90,000 a month in 10 years to stay identical.
• Debt — inflation quietly helps borrowers (a fixed EMI is paid in cheaper rupees later) and punishes lenders and fixed-income savers.

Real vs nominal

Economists split every money number into nominal (what it says on the note) and real (adjusted for inflation). When the GDP calculator shows nominal GDP, deflating it by the GDP price index converts growth to real terms — the same logic this calculator applies to your personal money. Whenever someone quotes a "return" on an investment, ask yourself: nominal or real? A 10% stock-market year in a 7% inflation year is only about a 3% real gain.

Using the calculator

• For a goal like "college fees in 2032", input today's cost and your best guess of 6–8% for education inflation — that real number is usually higher than headline CPI.
• For retirement, run your current monthly spend out to your retirement year, then feed that figure into the SWP calculator to see what corpus actually supports it.
• Inflation averaging 6% over six years is this tool's default; the RBI's stated comfort zone is usually expressed for CPI around the 2–6% band, but your own effective rate depends on your spending mix.

Inflation is uneven: food and housing often rise faster than the headline CPI number.
