A Beginners Guide to Calculate Future Value of Money

The money in your hand today is worth much more than tomorrow. If you do not invest regularly, an inflation parasite eats into it. So, whether you are planning for retirement or evaluating investment opportunities, understanding how to calculate the future value of money using inflation matters.

In this article, we will explore the concept of future value, discuss the factors that affect it, and give a step-by-step guide on calculating it accurately.

What is Future Value? 

Future value refers to the value that an investment or a sum of money will grow over a specific period, considering the effects of compounding. In other words, it quantifies the worth of an asset at a future date, assuming a particular rate of return.

Understanding the Formula:

Three important aspects must be considered to calculate the future worth of money: the original investment amount (present value), the interest rate, and the period. The following formula is used to determine future value:

Future Value = Present Value × (1 + Interest Rate) ^ Number of Periods

Let's break down the formula into its components to understand how each factor determines the future value.

  • Present value: The present value represents the initial money you invest or save. It works as the starting point for calculating the future value. For example, if you invest Rs 1,000 today, your present value would be Rs 1,000.
  • Interest rate: It is denoted in decimal or a percentage and determines the growth rate of your investment over time. It represents the return you expect to earn on your investment. For example, if the investment's interest rate is 5%, you would use 0.05 in the formula.
  • Number of periods: The number of periods refers to the time it will take for your investment to increase. It might be measured in years, months, or any other acceptable unit. For instance, if you wish to invest for five years, the number of periods is five.

How to Calculate the Future Value of Money?

Let's consider an example to demonstrate how to calculate the future value of money. 

Suppose you invest Rs 5,000 in a fixed deposit account with an annual interest rate of 4% for three years. To find the future value, we can apply the formula as follows:

Future Value = Rs 5,000 × (1 + 0.04) ^ 3

Simplifying the equation:

Future Value = Rs 5,000 × 1.04 ^ 3

= Rs 5,000 × 1.124864

= Rs 5,624.32

Therefore, after three years, your investment of Rs 5,000 would grow to approximately Rs 5,624.32.

The Power of Compounding

The formula for calculating future value incorporates the concept of compounding. Compounding refers to earning interest not just on the initial capital investment but also on the interest accrued over time. As a result, your investment can grow exponentially, especially when the interest is reinvested.

It is crucial to understand that compounding may work in your favor when investing, but it can also work against you when borrowing money. When borrowing, the future value indicates the amount owed, and interest compounds to increase the total repayment amount. A compound interest calculator can be used to determine how much your loan will increase over time.

Considerations and Practical Applications

  • Inflation: When calculating the future value, it is crucial to consider the effects of inflation. Inflation lowers the purchasing power of money over time. You may need to adjust the interest rate accordingly to account for inflation. You can use an inflation calculator to see how much your money will lose its value over time. This will help you make informed financial decisions, such as how much to save for retirement or how much to spend on a new car.
  • Different compounding periods: In practice, compounding periods can vary. Some investments compound annually, while others compound monthly, quarterly, or semi-annually. Adjust the rate of return and the number of compounding periods accordingly to match the investment's characteristics.
  • Financial planning: Understanding this concept enables better financial planning. It helps set realistic financial goals, evaluate investment opportunities, and determine the required savings or investment amounts to achieve specific targets.
  • Comparing investment options: By calculating this value, you can compare investment options to identify the one with the highest potential growth. This evaluation can guide you in making informed investment decisions.


As time progresses and economic factors fluctuate, the value of money has the potential to change dramatically. Through compounding and the power of investment, you can harness the future value of money to grow your wealth and achieve financial goals. However, it is crucial to remember that the future value of money is not guaranteed and is subject to various risks and uncertainties.
