how does fixed deposit work

A fixed deposit (FD) is a financial instrument offered by banks and financial institutions. It is a type of investment where you deposit a lump sum amount with the institution for a specified period, known as the tenure or maturity period. In return, the institution pays you a fixed rate of interest on your deposit at regular intervals (usually monthly, quarterly, or annually).

Investment Amount:

You start by depositing a specific amount of money (principal) in the fixed deposit account. This can be a one-time lump sum.

Interest Rate:

The financial institution offers a predetermined interest rate, which is applied to your principal amount. This interest rate is fixed for the entire tenure of the deposit.


You choose the duration for which you want to keep your money invested. Common tenures range from a few months to several years.

Interest Payouts:

The interest earned on the fixed deposit is paid out regularly, according to the agreed-upon frequency (monthly, quarterly, or annually). Some fixed deposits offer the option to reinvest the interest.


At the end of the specified tenure, the financial institution returns your principal amount along with the final interest payout. This lump sum is known as the maturity amount.
