What is the difference between a savings account and a fixed deposit account?

A Fixed Deposit Account is one in which the customer deposits a big sum of money (Usually a few thousands and upwards. There is actually no limit to the amount of money you can deposit in a FD) for a fixed duration of time (Atleast 3 months or higher). Since you agree to keep the money deposited with the bank for a fixed/agreed upon duration, the bank gives you a very good interest as payment for keeping the deposit

A savings account is one in which customers save their monthly savings and they are not like the current account. Though the money is available at any time for the customer to withdraw, money is not as frequently deposited/withdrawn from it like the current account. Hence banks offer a meager interest rate for the money held in this account
