Inflation is the general rise in prices across an economy. When inflation is 6% a year, something that costs ₹100 today costs about ₹106 next year. The flip side is that ₹100 held as cash buys a little less every year.
Why it matters
Inflation is the quiet force in every long-term plan. A retirement 25 years away, a child’s education 15 years away, a home 10 years away — each will cost far more in future rupees than it does today. Plans built on today’s prices tend to under-save. Inflation is also the hurdle every investment must clear before it adds to your real wealth.
How to read it
- Headline inflation in India is measured by the Consumer Price Index (CPI). Your personal inflation can differ, depending on what you spend on.
- Category inflation varies. Education and healthcare costs have often risen faster than general prices, which is why planning tools let you set a different rate for each goal.
- Small differences compound. Over 20 years, 6% inflation multiplies costs by about 3.2 times; 8% multiplies them by about 4.7 times.
Common misconceptions
- “My money is safe in a savings account.” Its rupee value is stable, but if the interest after tax is below inflation, its purchasing power falls each year.
- “Inflation is a one-year number.” For planning, the long-run average over your horizon matters far more than this year’s figure.
In India: The government has retained a 4% CPI inflation target for the Reserve Bank of India, with a tolerance band of 2% to 6%, for April 2026 to March 2031. CompoundX tools use editable, hypothetical inflation assumptions, not forecasts.
Formula
Future cost = Today’s cost × (1 + Inflation rate)^Years. Today’s value of a future amount = Future amount ÷ (1 + Inflation rate)^Years
Worked example
For illustration, assume a goal costs ₹10,00,000 today and inflation averages 6% a year. In 15 years it would cost about ₹10,00,000 × 1.06^15 ≈ ₹23,97,000.
