How to Build a ₹50 Lakh Corpus by Age 40

The exact monthly SIP needed at different starting ages, and the asset mix that gets you there.

6 min read8/5/2026

₹50 lakh is a popular early-life milestone — enough for a down payment in tier 1 cities, a child's foreign education seed, or a long sabbatical. The SIP you need depends almost entirely on how early you start.

Asset Mix

  • 10-15 years to goal: 90% equity index funds + 10% debt
  • 5-10 years: 70% equity + 30% debt
  • < 5 years: shift to 50:50 and rebalance annually

Step-Up to Make It Realistic

Most people can't start with ₹21,750 SIP at age 30, but they can start at ₹10,000 and step up 10-15% a year. A ₹10,000 SIP stepped up 15% annually reaches ₹50 lakh in roughly 11 years at 12% — without ever feeling the pinch.

Frequently Asked Questions

Is 12% return realistic over 10-15 years?

Nifty 50 has delivered 11-13% CAGR over rolling 15-year periods historically. 12% is a reasonable but not guaranteed planning assumption. Recalculate yearly and adjust SIP if returns lag.

Should I include EPF in this ₹50 lakh?

EPF is locked till retirement, so do not count it toward an at-40 lumpsum goal. Build this corpus separately in equity mutual funds.

What about real estate vs MF for this goal?

For a ₹50 lakh target with 10-15 year horizon, equity mutual funds win on returns, liquidity, and transaction costs. Real estate makes sense only for the home you live in.
