How Does a Fixed Deposit Work: A Comprehensive Example


Investing your hard-earned money is an important financial decision, and one popular option is a fixed deposit. Fixed deposits, also known as term deposits or time deposits, are a type of investment offered by banks and financial institutions. In this article, we will explore how a fixed deposit works through a comprehensive example, shedding light on its mechanics, benefits, and considerations.

To illustrate the concept, let’s consider an individual named Alice. Alice has recently received a bonus from her employer and decides to invest a portion of it in a fixed deposit. She approaches her bank, which offers competitive interest rates and flexible deposit tenures.

Step 1: Choosing the Bank and Tenure Alice begins by researching various banks to find the one that suits her needs. She compares interest rates, tenure options, and any additional benefits provided. After careful consideration, she selects Bank XYZ, which offers an interest rate of 7% per annum for a tenure of three years.

Step 2: Opening the Fixed Deposit Account Alice visits Bank XYZ and meets with a customer service representative to open her fixed deposit account. She provides the necessary identification documents, fills out the required forms, and deposits her desired amount of money, let’s say $10,000, into the account. The bank issues her a fixed deposit receipt, which outlines the terms and conditions of the deposit.

Step 3: Interest Calculation The interest on a fixed deposit is typically calculated on a compound interest basis, which means it accrues on the principal amount as well as any interest that has already been earned. In Alice’s case, the interest will be compounded annually.

Step 4: Monitoring the Deposit Throughout the tenure, Alice can monitor the progress of her fixed deposit. She can access her account details through the bank’s online banking platform or by contacting the customer service department. Alice can keep track of her investment, including the interest earned and the remaining tenure.

Step 5: Maturity and Redemption At the end of the three-year tenure, Alice’s fixed deposit matures. The bank notifies her about the maturity date and options for redemption. Alice has the choice to either withdraw the entire amount or reinvest it in another fixed deposit. If she decides to reinvest, she can explore different tenure and interest rate options available at that time.

Step 6: Interest Payout When Alice’s fixed deposit matures, she receives the maturity amount, which includes the principal amount and the interest earned over the three-year period. In this case, the interest earned will be calculated based on the 7% interest rate compounded annually. Let’s calculate the interest amount:

Principal amount: $10,000 Interest rate: 7% Tenure: 3 years

Year 1 interest: $10,000 * 7% = $700 Year 2 interest: ($10,000 + $700) * 7% = $770 Year 3 interest: ($10,000 + $700 + $770) * 7% = $854

Total interest earned over three years: $700 + $770 + $854 = $2,324

Maturity amount: Principal amount + Total interest earned = $10,000 + $2,324 = $12,324

Alice receives $12,324 at the time of maturity, and she can choose to reinvest this amount or utilize it for other financial goals.

Key Considerations:

  1. Interest Rates: Higher interest rates can significantly impact the returns on your fixed deposit. It’s essential to compare rates offered by different banks before making a decision.
  2. Tenure: Longer tenures generally offer higher interest rates. However, it’s crucial to align the tenure with your financial goals and liquidity requirements.
  3. Premature Withdrawal: If you need to withdraw the funds before the maturity date, banks usually impose penalties or reduce the interest rate earned. Make sure to understand the terms and conditions regarding premature withdrawals.
  4. Taxation: The interest earned on fixed deposits is subject to taxation as per the prevailing tax laws in your jurisdiction. Ensure you are aware of the tax implications and plan accordingly.
  5. Reinvestment Options: At the time of maturity, you have the option to reinvest the amount in another fixed deposit or explore alternative investment avenues. Evaluate your investment goals and market conditions to make an informed decision.


Fixed deposits are a popular investment choice for individuals seeking a secure and predictable return on their savings. Through the example of Alice, we have explored how fixed deposits work, including choosing a bank, opening an account, interest calculation, maturity, and redemption. As with any investment, it’s crucial to conduct thorough research, understand the terms and conditions, and consider your financial objectives before investing in a fixed deposit.
