​Financial planners say there are two broad approaches. One is valuation-based, where investors redeem or book profits when markets appear expensive and then use or redeploy the proceeds. The other is to set up a systematic withdrawal plan (SWP), which allows investors to withdraw a fixed amount at regular intervals, typically on a pre-defined date each month. To meet this payout, the fund house redeems the required number of units based on the prevailing NAV, while the remaining corpus continues to stay invested.
