What is an Inflation Calculator?

An inflation rate calculator measures the change in the purchasing power of money over time through an increase in the cost of goods or services due to inflation. The online calculator quantifies how inflation affects the real value of money by adjusting past and current figures for price changes.

An Inflation Rate Calculator shows how prices going up affect your money's worth over time. It is helpful for investors to see if their investments are growing more than their prices. It also helps decide where to put your money, like stocks or real estate, which can prove to be better against inflation than investments with fixed returns like Fixed Deposits (FDs).

This tool uses the Consumer Price Index (CPI) to measure how prices change. The CPI is a measure of how much it costs to buy a set amount of goods and services. It is adjusted regularly to reflect changes in the economy, so an Inflation Calculator can accurately tell you how your money's worth is changing. By understanding how inflation affects your money, you can decide where to invest it to get the best returns.

The rupee inflation calculator or the Indian rupee inflation calculator in the Indian scenario, serves as a valuable tool for people who are concerned about the purchasing power of their savings and investments. It empowers individuals to make informed financial decisions and adapt to the ever-changing economic landscape. By visualising the decline of their money's real value due to inflation, people can better plan for the future, ensuring their financial goals remain achievable.

How is Inflation Calculated?

Inflation is calculated primarily using the Consumer Price Index (CPI) and the Wholesale Price Index (WPI) and by measuring the change in the same over time. The inflation adjustment calculator helps in estimating the future value of goods or services by applying the inflation rate to compound the present value of the same for a desired period through the below formula:

Adjusted Value (Future Value) = Current Cost x (1 + Inflation Rate)^ Period (No of Years)


  • Current Cost – means the current value of goods and services.
  • Inflation Rate (per annum) – means an assumption of the percentage of inflation in the economy. (For India - the inflation has typically varied between 4% to 6% in recent times).
  • Period (No of Years) – means the duration over which the impact of inflation is considered.

Consumer Price Index (CPI):

The CPI in India is used to measure retail inflation, which reflects the changes in prices that consumers pay for a basket of goods and services.

The CPI is divided into several sub-indices, each representing different categories of goods and services, such as food, housing, clothing, transportation, and more.

Data is collected regularly from various locations across India to track the prices of items in the CPI basket.

The CPI is calculated by comparing the current cost of the basket of goods and services to a fixed base year. The index is expressed as a percentage relative to the base year.

Wholesale Price Index (WPI):

The WPI is used to measure wholesale inflation and reflects changes in prices at the wholesale level, typically for goods that are traded in bulk.

It tracks the price changes of commodities traded in the primary and secondary markets.

The WPI includes three major groups:

Primary Articles, Fuel and Power, and Manufactured Products. These are further divided into various sub-groups.

Similar to the CPI, the WPI uses a base year for comparison to calculate inflation.

Calculation of Inflation:

The inflation rate is calculated by comparing the CPI or WPI in the current period with the CPI or WPI in a previous period. This is expressed as a percentage increase.

In India, the most commonly reported inflation rates are Consumer Price Inflation (CPI) and Wholesale Price Inflation (WPI).

In recent times, inflation in India has remained in a narrow band of 4% to 6% and one of the aims of RBI is to manage inflation within a targeted band.

Impact of Inflation on Your Savings-

Inflation corrupts the purchasing power of savings, making them worth less over time, which can lead to reduced real wealth and financial security. This means that if savings don't outpace inflation, people may struggle to afford the same goods and services, potentially risking their financial goals. For when you hear your grandmother tell you stories about how Ghee used to be sold at 75 Paise per kilogram in 1947 and you pay more than Rs. 500 for the same today, it is the inflation which played the villain and resulted in the price rise.

Here is how inflation impacts how you plan your savings -

Financial Planning -To safeguard your savings from the impact of inflation, it's important to engage in comprehensive financial planning. This includes setting clear goals, creating a budget, and adjusting your strategy as your circumstances change.

Economic Factors-Inflation rates are affected by economic factors like government policies, monetary actions, global events, etc. Staying informed about these factors can help you adjust your savings and investment strategies as and when needed.

Poor Financial Goals-It is important that your savings grow faster than inflation. And if it does not then it becomes difficult to afford expensive things like home, education or comfy retirement. Inflation makes things cost more over time, so your savings also need to grow. It is important to invest and save wisely to keep up with rising prices.

Necessity to Invest Wisely-To combat the negative impact of inflation, you need to invest your savings wisely. Investments like stocks, bonds, and real estate have the potential to outpace inflation and protect your purchasing power. But also remember that these investments involve risk so it is suggested to conduct deep research before investing.

Reduced purchasing power-Inflation reduces the real value of money over time. The same amount of money saved today will have less purchasing power in the future, meaning you can buy fewer goods and services in the future as compared to how much and what you can buy today.

Inflation is like a never-ending aspect. It will gradually reduce the real value of savings, which can hamper financial goals. To balance this impact, you must invest wisely, diversify your portfolio, and take a long-term approach to financial planning.
