Is ₹40,000/Month for 18 Years the Right Plan for You?
A ₹40,000 monthly SIP sustained for 18 years is a specific commitment: ₹480,000 every year, ₹86,40,000 across the full tenure. The right question isn't whether the number looks big but whether it's sustainable. A rule of thumb: your monthly SIP should be no more than 25–30% of your take-home pay if you also have EMIs and living costs, and ideally you have a 6-month emergency fund parked in liquid funds or FD before committing to a long-horizon equity SIP.
At the 18-year mark, compounding contribution to final value is substantial. Of the ₹3,06,17,569 you hold at 12%, only ₹86,40,000 is your own money — the rest, ₹2,19,77,569, is market-driven compounding. This ratio grows dramatically with tenure: a 10-year SIP is mostly your capital with modest gains, while a 25-year SIP is mostly gains with modest capital. If you can stretch the horizon or amount, the curve bends sharply in your favor.
Fund allocation for a 18-year horizon: Equity-heavy is appropriate. Consider 70–80% in diversified equity (flexi-cap, large & mid-cap) with 20–30% in hybrid or debt for stability.
Step-up reality check: If you increase this ₹40,000 SIP by just 10% annually, your final 18-year corpus at 12% would be roughly ₹5,76,58,653 instead of ₹3,06,17,569 — an increase of about 88%. Most salaried investors can afford this because their income also grows annually.
