A bank account is a financial account maintained by a bank for a customer. There are several types of bank accounts including current accounts, savings accounts, fixed deposits, recurring deposits, and no-frills accounts. Current accounts are for businesses and allow prompt transactions without interest. Savings accounts are for individual depositors and earn modest interest. Recurring deposits require regular fixed deposits over a period of time, while fixed deposits involve lump sums for a set time at higher interest rates than savings accounts. No-frills accounts provide basic banking facilities with zero or low fees.
