LET YOUR MUTUAL FUND PORTFOLIO MANAGE YOUR SABBATICAL

1. As you're aware, a sabbatical is short-term in nature as compared to retirement, and a 3-yr sabbatical would entail an outgo of 36 times your monthly expenses by way of monthly Systematic Withdrawal Plans (SWPs).
2. For this, you will require a corpus of 30-33 times of your monthly SWP amount to be invested at 11%-7% CAGR.
3. Being a short duration need, you could :-
a) Hive off this corpus amount into a single liquid fund, or a flexi-deposit account linked with your savings account, @ 7% CAGR, after redeeming part of your existing funds, and then activate monthly SWPs, or
b) Utilize your existing funds for activating monthly SWPs directly from them, while their corpus continues to grow at 8%-11% CAGR, albeit with moderate risk, starting with large cap funds and availing LTCG tax benefits to the maximum extent possible.
4. During this exercise, you could also weed out funds that may have outlived / underperformed, in order to declutter your portfolio, which will hold you in good stead after the sabbatical.
5. During the sabbatical, you could also keep reinvesting your net savings from your monthly SWPs (by exploring options of optimizing monthly expenses) into your decluttered portfolio, even as lumpsum ad-hoc amounts whenever possible, for continuous growth of your corpus.
