A fixed deposit or FD is a relatively secure investment that banks and financial institutions offer. In this type of investment, investors lock in the deposit for a predetermined period, which varies from a few months to several years. So, before investing in an FD, you would want to know how much interest you will get in the end. While the math involved is simple, it can be made simpler still with an FD calculator.

What is the fixed deposit calculator?

Our FD calculator is an online tool that helps you estimate the maturity amount of your FD. It also can be used to compare different tenures with different interest rates from different institutions. In this way, it makes deciding which bank and what tenure to choose a lot easier. All you need to do is go for the highest maturity amount.

How can an FD calculator help you?

The benefits of an FD calculator should be somewhat clear from the discussion above. But to make things clearer still, let’s break down how it can help investors a little more. The calculator can help in the following ways:

  • The calculator can help investors factor in multiple variables.
  • The calculator reduces the time taken for the calculation.
  • FD calculators like the one above help compare the maturity amount and interest rates of various schemes. This lets investors choose the most suitable one with ease.

Formula to calculate FD maturity amount

FD are of two types—simple interest FDs and compound interest FDs. The fixed deposit calculator here is for simple interest FDs and relies on the following formula:


MV = (P x r x t)/100


MV is the total amount at the end of the FD tenure

P is the principal amount or initial deposit

r is the rate of interest; and 

t is the tenure of the FD in years


Please note that some variations of the formula may consider additional factors such as compounding intervals or the inclusion of simple interest.


The FD calculator we have does the math for you, though.

Benefits of using an FD Calculator 

The FD calculator above comes with several benefits for new as well as seasoned investors. Let’s identify some of them here.

  • Simplifies investment calculations

With an FD calculator, investors can quickly determine the potential returns on their investments without the need for complex manual calculations. It takes key variables into account and calculates the maturity amount and interest earned. This tool thus equips people to make informed decisions by helping compare different investment options.


  • Evaluates associated risks

A fixed deposit calculator’s primary role is to calculate returns from FDs. However, it can be used to evaluate risks associated with it, too. Because when potential returns are low, the risk is high. For investors who are risk-averse, the calculator thus serves as a valuable tool.

  • Saves time

Crunching numbers is not everyone’s cup of tea, and even for those good in calculations, it can take a lot of time. An FD calculator helps investors save time by automating complex calculations and providing accurate results instantly.

  • Helps you make informed decisions

FD calculators like the one here encourage investors to adopt a broader perspective on their financial journey. By gaining clarity on potential returns, investors can explore additional investment opportunities and diversify their portfolios.


They also help optimize returns and reduce risk. This ensures that they are better equipped to adopt a more strategic and effective financial plan.


An FD calculator is a tool that estimates the maturity amount and interest earned on FDs. It helps calculate and compare potential returns quickly. The tool is also free and easy to use. We hope you use it to your advantage.
