Inflation Calculator

Inflation is the gradual rise in the general price level. It means a given sum buys less each year, so long-term goals must be planned in future rupees, not today's.

Enter an amount, an assumed annual inflation rate and the number of years.

Assumptions used
  • A single constant inflation rate for the whole period.
  • Category-specific inflation (education, healthcare) can be much higher than the headline rate.

Inflation formulas

Future cost = Present amount × (1 + i)^n

  • i = annual inflation rate ÷ 100
  • n = number of years

Future purchasing power of today's amount = Present amount ÷ (1 + i)^n

Worked example

  1. A ₹1,00,000 annual expense, 6% inflation, 10 years.
  2. Future cost = 1,00,000 × (1.06)^10 ≈ ₹1,79,085.
  3. The same ₹1,00,000 kept idle would buy only about ₹55,840 worth of goods in today's terms.

Why this matters for planning

  • Retirement: your monthly expense at 60 will be far higher than today's. Plan the corpus on the inflated figure.
  • Education: fees for professional courses have historically risen faster than general inflation.
  • Investments: an asset must beat inflation after tax just to preserve your wealth.

Real vs nominal return

Real return ≈ (1 + nominal return) ÷ (1 + inflation) − 1. A 7% fixed deposit with 6% inflation gives a real return of under 1% before tax, which is why long-term goals usually need some growth assets.

Frequently asked questions

What inflation rate should I use for India?

Headline CPI inflation in India has often hovered around 5–6% over the past decade, with specific categories like education and healthcare running higher. Use a rate that reflects your own basket of expenses.

What is purchasing power?

The quantity of goods and services a unit of money can buy. Inflation reduces purchasing power over time, so the same rupee amount buys less in the future.

How does inflation affect my savings?

Money kept in cash or a low-interest account loses real value every year. To protect purchasing power, the after-tax return on your savings must at least match inflation.

Is a fixed deposit enough to beat inflation?

Often only marginally, and sometimes not after tax. FDs are useful for stability and short-term goals; long-term goals usually need a mix that includes growth assets.
