A Systematic Withdrawal Plan (SWP) is a facility offered by mutual fund companies that allows investors to withdraw a fixed amount or a specified number of units from their mutual fund investment at regular intervals. SWP is essentially the opposite of a Systematic Investment Plan (SIP), where instead of investing money regularly, investors withdraw money systematically. SWP is commonly used by investors who are looking to generate regular income from their investments, such as retirees or those in need of supplemental income.
