Fixed Deposit or FD is an investment option given by banks and non-banking financial companies (NBFCs). It is one of the easiest ways to earn interest on your money. You can deposit a large amount with the bank or NBFC and earn a regular income in the form of interest, which is higher than savings account interests and carry no market-related risks.
For building your savings for short-term goals, a savings account can be the most preferred option. When you have surplus cash, depositing this in your savings account will fetch you interest. This interest is taxable.
