What is inflation?

By definition, inflation measures the general price rise in an economy. In layman’s terms, what you can buy with ₹100 today will cost you ₹104 the following year if the prevailing inflation rate in the economy is 4%. 


Inflation measures the price fluctuations for a pre-determined basket of goods and services. The rate of inflation is expressed in percentage terms.  

Inflation calculator explained

The inflation rate that you see on news channels is declared and monitored by the Reserve Bank of India every month. Calculating inflation is a complex process. A department under the Ministry of Statistics and Programme Implementation collects data every month to calculate the Consumer Price Index (CPI). 


Since calculating the inflation number is complex, you won’t be able to do it yourself. Thankfully, the CoinSwitch calculator will help you measure the impact of inflation on your investments and expenses in the coming years. Knowing how your costs will increase in the coming years will help you save in a way that might help you beat inflation. 

How to use the inflation calculator


The inflation calculator is easy to use. You need to fill in the following details in the appropriate fields to get the inflation-adjusted number: 


  • The present value of your expenditure 
  • The inflation rate for the year 
  • The period for which you wish to check the impact of inflation


Let’s understand the impact of inflation on expenditure. Your current monthly household expense is ₹60,000 and the inflation rate in the economy is 5.5%. This means your inflation-adjusted expense for next year will be ₹63,300. This denotes the increase in your expenditure even if you maintain the same standard of living and do not incur any extra expenses.
