Interpretation

What does this loss of purchasing power mean?

Due to 6% annual inflation, a lifestyle or item costing ₹1,00,000 today will cost ₹1,79,085 in 10 years. Conversely, ₹1,00,000 kept idle in cash will buy only ₹55,839 worth of goods — losing 44% of its value!

  • Inflation is the hidden tax that hurts idle cash and low-interest bank savings accounts.
  • To preserve your wealth, your investment portfolio must earn a post-tax return greater than retail inflation (typically 6–7% in India).
  • Education, housing, and healthcare inflate at 8–12% annually, well above official headline CPI indices.
Calculation Methodology

How This Calculator Works

The compound inflation formula computes future expenditure requirements, while the purchasing power multiplier (1 / (1 + Inflation)^t) measures how much a fixed sum shrinks in real terms.

Future Cost = Present Cost × (1 + Inflation)^t

Variables in Formula:

Future Cost: Equivalent rupee amount needed to buy the same basket in year t
Future Purchasing Power: Value of today's money expressed in future purchasing units
Purchasing Power Loss: Percentage of real purchasing capability eroded by price rise
Real-World Scenario

Worked Step-by-Step Example

Keeping ₹5 Lakhs in a standard savings account earning 3% for 15 years with 6% annual inflation.

Starting Capital₹5,00,000
Future Cost of ₹5L Basket₹11,98,280 (2.4x)
Real Purchasing Power Left₹2,08,630 (58% loss)

Key takeaway: Keeping money in 'safe' cash over long periods is actually high risk because inflation guarantees the loss of your purchasing power.

Common Traps

Common Mistakes to Avoid

Focusing solely on nominal returns instead of real returns

A 7% Fixed Deposit taxed at 30% yields ~4.9% post-tax. If inflation is 6%, your real return is -1.1% per year.

Using headline CPI to plan for college or hospital costs

Higher education and private healthcare in India inflate much faster than food and fuel indices. Build higher assumptions for these specific goals.
