Asset Allocation for Your Age

~15 min  ·  You'll know exactly how to split your portfolio by asset class  ·  ← Lesson 7  ·  Glossary

The decision that matters more than which stock you pick

Studies consistently show that over 90% of a portfolio's long-term returns and volatility are explained by asset allocation — how you divide money across broad asset classes — not by which specific stocks or funds you choose. You can spend months agonising over Fund A vs Fund B and it won't matter as much as getting this one thing right.

The three main asset classes for an Indian retail investor:

The rule of thumb: 100 minus your age

A classic starting point for equity allocation:

Equity % = 100 − Your Age

At 30: 70% equity, 30% debt + gold. At 50: 50% equity, 50% debt + gold. The logic: younger investors have more time to ride out market downturns and recover, so they can afford more equity. As you approach retirement, you shift toward stability.

This is a guideline, not a rule With longer life expectancies and decades of compounding available, many modern planners use 110 or 120 minus age instead of 100. And if you have a stable job, low fixed costs, and a full emergency fund, you can lean higher on equity. Use this as a starting point, not a rigid constraint.

What to put in each bucket

Equity (growth engine)

Debt (stability)

Gold (hedge)

For your situation You have an EPF (mandatory) and a home loan. Your EPF contributions already act as your debt allocation. This means your SIP allocation can lean heavier into equity than the raw 100-minus-age calculation suggests. Run the numbers with your actual EPF balance included.

Rebalancing: one task per year

Over time, your allocation will drift — equities tend to grow faster and will become a larger share of your portfolio. Rebalancing corrects this by trimming what's grown too large and adding to what's fallen behind.

Check your understanding

Q1 — You are 32 years old. Using the 100-minus-age rule, what is your suggested equity allocation?

Q2 — Your portfolio is 80% equity vs a 70% target. Markets were up this year. What should you do at year-end?

Q3 — Which is the best way to hold gold as part of your portfolio?

  1. Use the slider above to find your suggested allocation for your age.
  2. Add up your current holdings by category (EPF = debt, any FDs = debt, any equity funds = equity).
  3. Compare your current allocation to the target. Note where you are under-weight — that's where new SIP money should flow first.
