Amid so many complicated financial products available in the market, fixed deposits or FDs are popular with conservative investors who want a decent return and complete safety for their investments. An FD allows investors to lock the principal amount for a period ranging from a few days to years. During this lock-in period, investors get interest on their deposits and the interest rate depends on the bank or financial institutions that offer the product. If you are keen on investing in FDs, you would want to know how much interest you will get. Our FD calculator will make your task easier. Let’s learn more about this useful tool.

Fixed deposit calculator, explained

Fixed deposit or FD calculator is an online utility tool that allows users to calculate the interest they will gain once their investment reaches its maturity date. The calculator offers flexibility, allowing users to play around with different principal amounts, rates of interest, and tenure to select the best option available. 

Different uses of an FD calculator

Although a simple tool, an FD calculator can help investors in several ways other than just estimating the returns from an FD investment. For one, the calculator provides investors with quick and error-free results since manual computation can take a lot of time and mistakes could creep in easily. Users can also compare FD options provided by various institutions. Thus, the FD calculator online helps individuals to plan their investments better.

The math behind calculating the FD maturity amount

If you would like to stretch your mind a bit, there are two formulas you can use to calculate the maturity amount of an FD—simple interest formula and compound interest formula. 

Simple interest (SI) formula 

(SI) = P × T × R ⁄ 100


In the formula above, 

P indicates the initial principal balance

R indicates the annual interest rate

T indicates time 


Compound interest formula


A = P(1 + r/n)^nt


In the formula above, 

A indicates the maturity amount

P indicates principal amount

r indicates the rate of interest

n indicates the number of times the interest is compounded annually

t indicates the overall tenure.


But the easy and accurate way out is to use the FD interest calculator online.
