Auto sweep facility is a feature offered by banks that connects your savings account to a fixed deposit account, allowing you to earn higher returns on the excess or idle money in your savings account. The auto sweep feature "sweeps" excess funds from savings into a fixed deposit account, and you must connect these two accounts and establish a monetary limit. Whenever the amount in the savings account crosses that defined limit, the excess money is transferred automatically into the fixed deposit. The sweep-in FD facility helps you build a corpus that you can access in an emergency without liquidating any other assets and offers a higher interest rate. Auto sweep accounts charge penalties for premature withdrawal of funds, so you cannot withdraw money from this account until maturity, or else you must pay the penalty. The auto sweep facility is beneficial for maintaining a healthy balance between your savings and investments, and it ensures a good return on your funds. The best use of this auto-sweep facility is when your savings account has stagnant excess deposits to avoid penalties for premature withdrawal. The sweep-in facility provides the same liquidity as a savings or current account.
