The mechanism of systematic withdrawal and transfer, and which one suits which purpose
Published by The Retail Trader · JUL 31, 2026 · Mutual Funds & AMC
A SIP is the systematic way to put money in. It has two siblings — SWP for taking money out, and STP for shifting from one fund to another. All three share the same logic: decide once, execution is automatic.
In an SWP, a fixed amount arrives in your bank every month. To fund it, as many units are redeemed as are needed at that day's NAV.
In an STP, a fixed amount moves every month out of one scheme and into another, often from debt towards equity.
They are generally used in these situations:
• An SWP for regular income after retirement, because there the control is yours.
• An STP to put a large amount into equity gradually.
• An STP also to shift from equity to debt as a goal approaches.
• In both, every transaction is a redemption — which means both tax and load can apply.
If the SWP amount is set higher than the portfolio's growth, the corpus slowly runs out — that is not a flaw, just arithmetic. Deciding the withdrawal rate in advance is the real decision in this whole mechanism.
