A Systematic Withdrawal Plan (SWP) calculator helps you manage your investments by estimating regular withdrawals, allowing you to receive a steady income over time. By inputting your investment amount, expected rate of return, withdrawal frequency, and time period, the calculator determines how much you can withdraw periodically without exhausting your funds. This tool is useful for retirees or anyone seeking to plan their cash flow, offering insight into how long their investments will last while meeting financial needs. It is especially helpful for those aiming to balance withdrawals with potential growth in their portfolio.
