How to Calculate Inflation Rate in India

In India, inflation is calculated using the consumer price index. The weighted average value of each is used to assess changes in goods and service pricing.

CPI = (Cost of Fixed Basket of Goods and Services in Current Year/ Cost of Fixed Basket of Goods and Services in Base Year) x 100

Remember to get the CPI for two years to calculate the inflation rate.

How to Use ClearTax Inflation Calculator

Using the ClearTax inflation calculator, knowing and understanding how inflation can affect your overall savings is very easy. To use the calculator, follow the below steps:

  • Enter the value of the current expenses.
  • Mention the inflation rate percentage. It should be the current rate.

  • The calculator will tell the exact amount based on your entered information.

How to Calculate Future Value

You can use the future value calculator or the formula below to calculate this value. This value is the value of a particular asset in the future on a specific date based on a certain growth rate. The formula for calculating future value is:

FV = PV*(1+i)^n

In this formula, 

  • PV = present value of the goods
  • I = interest rate
  • N = number of periods

Let’s understand how to calculate this value using an example:

Let’s assume Ajay holds an asset and wants to know its value in the future. The different components that are required are as follows.

PV = 2,50,000

I = 12%

Time period = 5 years

So, FV = 2,50,000*(1+12%)^5 equals to 4,40,585

Impact of Inflation on Savings

Let’s understand how inflation impacts your savings using the cost of a product or service. For instance, if today the expense of child education is INR 15,00,000/-, this rate will change with inflation. Now, if there is an inflation of 6%, you will have to save another 6% for your child’s education. So, with this inflation rate, the cost of education in the next ten years will be INR 26,86,000/-.

With inflation, the same goods or services are expected to cost more in the coming future. That is why investing and saving money is imperative to fight inflation.
