What is a Systematic Withdrawal Plan (SWP)?
A Systematic Withdrawal Plan (SWP) is an investment structure that allows investors to withdraw a fixed amount of money at regular intervals from a mutual fund, ETF, or investment portfolio. SWPs are commonly utilized by retirees to generate regular monthly income from their accumulated retirement nest egg.
The Mathematics of SWP Balance Growth
The balance of an SWP account changes monthly based on the regular withdrawal deductions and the compounding growth rate:
If the monthly withdrawal amount is lower than the monthly interest earned on the principal, the initial investment will continue growing over time. Conversely, if withdrawals exceed interest, the principal will deplete.
