Inflation historical data of India Source: World bank
In a simple term, inflation means an increase in the price of goods and services over a certain period. If the price of a pen was Rs 100 last year and the inflation is 4% means then the price of the pen this year is Rs 104. The value of Rs 100 last year and Rs 104 in current are the same. So as per the rule of 70(inflation)
Duration of your wealth reduced into half = 70/ current inflation rate
14 = 70/5
Assume inflation rate as 5% for next few years. Then 70/5 is 14. In 14 years the value of your wealth is reduced to half. If you bought 10 pens for Rs 100 the after 14 years you can buy only 5 pens for Rs 100. So you should wisely choose an investment plan which is more than an inflation rate.
Comparison.
Suppose if you invested Rs 1 lakh in fixed deposit at 7% rate of interest. In the same years, the inflation rate also the same 7%.
As per the rule of 72, 72/7 = 10.28 years
According to the rule of 70, 70/7 = 10 years
As per the rule of 72, your 1 lakh looks like grown into 2 lakhs in 10.28 years. But if you look closely at inflation the worth of 2 lakhs after 10 years is equal to the worth of 1 lakh in the current year. But when the inflation rate is 3% choosing an investment plan at 8% or more will makes your money grow.
