What is a Fixed Deposit?

Fixed deposits are one of the savings options for consumers seeking guaranteed returns on deposits. A fixed deposit is an account opened with a bank in which the bank guarantees the interest rate on the funds deposited for a set length of time. Creating a FD enables you to earn better returns on idle funds in your Savings Account. 

How Do Banks Operate?

Banks operate in two distinct verticals: borrowing and lending. A bank provides a secure location for people and businesses to store their assets. Banks pay clients interest on their deposits, depending on the type of account.

  • Savings Bank accounts earn interest but have limits on the number and quantity of withdrawals.
  • Current accounts always offer liquidity and have no account or fund usage restrictions. As a result, they do not demand any interest payments.

Along with Savings and Current Accounts, banks encourage customers to open Fixed Deposits and Recurring Deposits by offering higher interest rates. This raises revenue for the bank. Technically, the bank is 'borrowing' money from you.

The bank undertakes lending operations using cash accumulated through various accounts. Most banks provide a wide range of home, business, personal, and car loans and charge interest on them.

The bank's income is calculated as the difference between the interest it makes on loans and the interest it pays out on deposits. Now that we understand how a bank operates, let's learn how an FD works.

How Does a Fixed Deposit Work?

Banks offer Savings Accounts and Current Account services. Depositors in these accounts can withdraw their funds at any time. Current accounts have zero balance requirements and cannot be estimated. Banks require a consistent supply of capital to disburse loans, and the best option for them to raise this cash is to provide Fixed Deposits. 

In a FD, the bank holds a specific amount of money for the deposit period. Banks allow depositors to create fixed deposits for seven days to ten years. The deposit's interest rate is determined by how long the money is held in the bank.

The depositor is not permitted to withdraw money before the due date. Some banks allow early withdrawals but at a lesser interest rate. The bank transfers the principal and interest to the depositor's account on maturity. 

Thus, if you decide to open an FD, you should know the interest rate, tenure, and other essential aspects of the offering before locking away your assets for a set period. You can also use the FD calculator to calculate the FD amount and interest you will earn, allowing you to make an informed decision.

Advantages of Fixed Deposit-

Fixed Deposits are one of the most preferred investment options for individuals seeking stability and predictability in their returns. They offer a simple way to grow savings without being affected by market fluctuations, making them suitable for conservative investors. With flexible options and easy accessibility across banks, FDs continue to be a reliable choice for both short-term and long-term financial planning. Some of the advantages of fixed deposits are mentioned below-

Assured Returns-

The assured rate of return is the primary reason individuals prefer to invest in FDs. When you invest your money in a fixed deposit account, you are assured of getting the specified rate of return. Banks also feature a fixed deposit interest calculator on their websites, allowing customers to determine the interest they earn for investing a specific amount of money for a particular time. 

Tax Threshold For Interest-

Banks are not required to deduct tax on interest unless it exceeds the income tax threshold, which provides relief to small deposit holders.

Flexible Tenure- 

The deposit holder determines the tenure of the fixed deposit. Each bank has minimum tenure standards, although the deposit holder can decide. The deposit holder can also choose whether to redeem or extend the FD simultaneously. 

Liquidation- 

Fixed deposits can be liquidated very easily. FDs booked online can also be liquidated online using net banking. Otherwise, most bank locations provide a form for liquidating the FD. 

Loan Against FD- 

Obtaining a loan against a fixed deposit is relatively simple. Depending on the bank, you can take out a loan for up to 95% of your FD. This makes it a reliable investment.
