Step Up SIP Calculator

An Inflation Calculator helps you measure how inflation affects the purchasing power of money over time. Enter an amount and time period to instantly see how the value of money changes and plan smarter financial decisions.

Latest Inflation Update:

The Reserve Bank of India (RBI) released an expected inflation, as measured by the Consumer Price Index (CPI), to average around 3.7% for the financial year 2025–26. The quarterly breakdown is:

• 2.9% in April–June (Q1).
• 3.4% in July–September (Q2).
• 3.9% in October–December (Q3).
• 4.4% in January–March (Q4).

Although these numbers appear stable, inflation still means that prices are gradually rising, which can erode the purchasing power of your money over time.

That’s why using an inflation calculator can be helpful. It shows you how inflation affects the value of your money, helping you plan better for the future. By understanding this, you can make more informed financial decisions to protect your savings and investments from losing value.

What is the Inflation Calculator?

An inflation calculator is a financial tool that helps you understand how the value of money changes over time due to inflation. By entering an amount of money, a base year, and a target year, the calculator displays the value of that amount in today's terms or in the future, taking into account inflation. 

This helps you measure the real purchasing power of your money across different time periods, making it useful for budgeting, investment planning, and setting long-term goals.

Why Inflation Calculator Used for?

An Inflation Calculator helps you understand how the value of money changes over time due to inflation. By entering the current amount and number of years, the calculator quickly shows how much that money will be worth in the future or how much prices may increase. 

This makes it easier to plan for future expenses, savings, retirement, and investments by giving a clear idea of how inflation can impact your purchasing power.

How to use the Inflation Calculator?

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

• Step 1: Enter the value of the current expenses.
• Step 2: Mention the inflation rate percentage. It should be the current rate.
• Step 3: Enter the period in years for which you want to understand the future price.
• Step 4: The calculator will display the exact amount based on the information you entered.

You can even use it as an inflation calculator by year to understand how the prices will change.

Formula to Calculate Inflation

To understand how an inflation calculator works, you need the Consumer Price Index (CPI) values for two different time periods. These values allow you to calculate the inflation rate using the formula:

Inflation Rate = [(CPI in Year 2 – CPI in Year 1) / CPI in Year 1] × 100

Let’s apply this using RBI’s projected CPI data.

Assume the CPI for 2024–25 is 100 (base value), and for 2025–26 it is expected to rise by 3.7% (based on RBI’s average projection for 2025–26).

That means the CPI in 2025–26 will be:

CPI in 2025–26 = 100 + (3.7% of 100) = 103.7

Now applying the formula:

Inflation Rate = ((103.7 – 100) / 100) × 100 = 3.7%

This confirms that with a 3.7% increase in CPI, the inflation rate is 3.7%. 

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

Where,

• 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 following components are required.

• PV = 2,50,000
• I = 12%
• Time period = 5 years

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