A Fixed Deposit (FD), also known as a term deposit or time deposit, is a secure investment option where you deposit a lump sum of money for a fixed period at a predetermined interest rate. Banks and other financial institutions offer FDs, and they provide guaranteed returns. While the money is locked in for the agreed-upon term, the interest rate and returns are fixed, offering a safe and predictable way to grow savings. Fixed Deposits investments can be one time or recurring. Likewise, the interst can be taken monthly, quarterly, half yearly, yearly or at maturity.
