Understanding Inflation
Inflation is the rate at which the general level of prices for goods and services is rising, and, subsequently, purchasing power is falling. Central banks attempt to limit inflation, and avoid deflation, in order to keep the economy running smoothly. For an investor, inflation is the 'invisible enemy' that erodes the real value of returns over time.
What is Inflation?
It is the rise in the prices of most goods and services of daily or common use, such as food, clothing, housing, recreation, transport, consumer staples, etc. Inflation measures the average price change in a basket of commodities and services over time.
Inflation Formula
The calculator uses the standard compound interest formula to project future costs:
The Formula:
- FV= PV × (1 + r/100)^n
- FV= Future Value (Future Cost)
- PV= Present Value (Current Cost)
- r= Rate of Inflation (%)
- n= Time Period (Years)
Calculation Example
If your monthly household expense is ₹50,000 today, and inflation is 6%:
- Current Cost: ₹50,000
- Inflation Rate: 6%
- Time: 20 Years
- Future Cost = 50,000 × (1.06)^20
- Result = ~₹1,60,356 per month
