About the Inflation Calculator

Inflation erodes the purchasing power of money over time. ₹1,00,000 today will buy significantly less in 10 years due to rising prices. India's CPI (Consumer Price Index) inflation has averaged around 5–6% annually over the past decade, peaking above 8% in 2022–23 due to global factors. Understanding inflation is essential for long-term financial planning - especially for retirement.

Inflation-Adjusted Value

Future Value = Present Value × (1 + inflation rate)^years

To find present value of a future sum: PV = FV / (1 + r)^t · Real return = ((1 + nominal return) / (1 + inflation)) − 1

Worked Example

Monthly expenses of ₹50,000 today - what will they cost in 20 years at 6% inflation?

Current Monthly Expenses:₹50,000
Inflation Rate:6% p.a.
Years:20

Future monthly expenses ≈ ₹1,60,357 · You'll need 3.2× more income just to maintain the same lifestyle

Tips & Insights

  • 1

    Your investments must beat inflation to grow your real wealth - FDs at 7% with 6% inflation give only 0.94% real return.

  • 2

    Food and healthcare inflation in India has historically been higher than headline CPI - budget accordingly for these categories.

  • 3

    Use 6% as a conservative inflation estimate for general planning, 8% for healthcare, and 10% for education costs.

  • 4

    Equity mutual funds have historically delivered 10–15% returns in India - well above the 6% average inflation.

  • 5

    Retirement corpus planning must account for 25–30 years of inflation, meaning you need 4–5× your current annual expenses.

Why this matters for you

A retirement corpus that seems large today may be inadequate in 20 years. At 6% inflation, ₹1 crore becomes worth only ₹31 lakh in real terms after 20 years. This is why financial planners insist on inflation-adjusted retirement planning - and why equity investments (not FDs) are necessary for long-term goals.
