Asset Allocation and Rebalancing: How to Split Money Between Equity, Debt and Gold
Your mix of equity, debt and gold decides most of your long-term result and most of the pain along the way. Rebalancing keeps that mix from drifting, and forces you to buy low and sell high without predicting anything.

Key takeaways
- Asset allocation, the split between equity, debt, gold and cash, sets both the expected return and the size of the falls you must live through.
- Start from the goal: money needed within three years should not depend on equity; money for goals 7 or more years away can carry more equity.
- Markets push a portfolio away from its target. Rebalancing brings it back, which means trimming what has risen and adding to what has fallen.
- Rebalance on a schedule (once a year) or when an asset drifts more than about 5 percentage points from target, whichever comes first.
- Rebalance with new money and SIP redirection first; when you must sell, use the ₹1.25 lakh yearly exemption on long-term equity gains and avoid short-term gains.
Ask most investors how their portfolio is doing and they will name a fund or a stock. Ask how it is split, between equity, debt and gold, and many will not know. Yet that split, called asset allocation, decides most of what happens to their money: how much it is likely to grow, and how much it can fall in a bad year.
This guide explains how to set an allocation, why it drifts, and how to rebalance it in a way that is simple, disciplined and tax-aware in India.
What each asset class does
| Asset class | Examples | Role | Main risk |
|---|---|---|---|
| Equity | Index funds, equity mutual funds, shares | Long-term growth above inflation | Falls of 30% to 50% in bad years; can stay down for years |
| Debt | EPF, PPF, FDs, debt funds, bonds | Stability, income, money for near-term goals | Inflation eroding returns; credit or interest-rate risk in some funds |
| Gold | Gold ETFs, gold funds, existing SGBs | Diversifier, often rises when equity or the rupee is under stress | No income; long flat periods |
| Cash | Savings account, liquid fund | Emergency fund and spending money | Low return |
The point of combining them is that they do not all fall together. In March 2020, the NIFTY 50 fell 38% in about two months, while high-quality debt barely moved and gold rose. A portfolio with some debt and gold fell much less, and its owner was in a far better position to hold on, or even buy.
Setting your allocation
Start from the goal, not from the market
Each goal has a time horizon, and the horizon decides how much short-term volatility the money can survive:
| When you need the money | Typical equity share | Why |
|---|---|---|
| Within 3 years (house down payment, car, fees) | 0% to 20% | An equity fall of 30% just before the goal could not be recovered in time |
| 3 to 7 years | 30% to 50% | Some growth, but a bad year must be absorbable |
| 7 years or more (retirement, children's higher education) | 50% to 80% | Time to recover from several bad years; inflation is the bigger risk |
Then adjust for you
- Income stability. A government employee with a pension can carry more equity than a freelancer with irregular income.
- Existing debt assets. Count EPF, PPF and FDs. A salaried person with a large EPF balance may already have 40% in debt without any debt funds.
- Behaviour. The right allocation is the one you will not abandon in a crash. If a 30% fall in your equity would make you sell, hold less equity.
Multiply your equity amount by 0.4. That is roughly what a severe bear market could take away. If that number in rupees would cause you to sell, your equity share is too high.
Why portfolios drift
Suppose you start with ₹10 lakh at 60% equity and 40% debt. A year later the mix depends on what markets did:
| Scenario | Equity | Debt | Total | Rebalancing trade |
|---|---|---|---|---|
| Start | ₹6,00,000 (60%) | ₹4,00,000 (40%) | ₹10,00,000 | — |
| Equity rises 30%, debt earns 7% | ₹7,80,000 (64.6%) | ₹4,28,000 (35.4%) | ₹12,08,000 | Sell ₹55,200 of equity, buy debt |
| Instead, equity falls 30%, debt earns 7% | ₹4,20,000 (49.5%) | ₹4,28,000 (50.5%) | ₹8,48,000 | Buy ₹88,800 of equity from debt |
After a strong year you hold more equity than you planned, so your portfolio is riskier than you chose. After a weak year you hold less. Left alone over several good years, a 60:40 portfolio can drift to 70:30 or more, just as valuations are high and a fall would hurt most.
A real-data illustration, 2019 to 2026
To see how this works in practice, we ran ₹10 lakh at 60:40 through the actual monthly path of the NIFTY 50 from 1 Feb 2019 to 5 Oct 2026, assuming debt earned a steady 7% a year. One version rebalanced back to 60:40 every January; the other never rebalanced.
| Portfolio | Final value | Equity share at the end | Worst fall from a peak |
|---|---|---|---|
| 60:40, rebalanced every January | ₹19,18,307 | 55.0% | -18.7% |
| 60:40, never rebalanced | ₹19,06,903 | 64.8% | -19.1% |
| 100% NIFTY 50 (price index) | ₹20,58,259 | 100% | -32.2% |
Over this short and specific period the two 60:40 versions ended close together; rebalancing is not a reliable way to earn extra return. What it did was keep the risk where the investor chose it. Note also that both balanced portfolios fell far less than the all-equity one in the 2020 crash, which is the main reason to hold debt at all.
How and when to rebalance
Two rules, used together, cover most needs:
- Calendar: review once a year on a fixed date, such as your birthday or the start of the financial year.
- Threshold: also rebalance whenever an asset class drifts more than about 5 percentage points from its target, for example equity above 65% or below 55% on a 60% target.
Rebalancing does not have to mean selling. In order of preference:
- Direct new money, including SIPs, bonuses and maturing deposits, to the asset that is below target.
- Redirect SIPs temporarily: pause the equity SIP and raise the debt SIP for a few months, or the reverse.
- Sell only if you must, and do it tax-efficiently: sell equity units held over 12 months, keep each year's long-term gains near the ₹1.25 lakh exemption, and avoid units under 12 months old, which are taxed at 20% as short-term gains.
Gains on debt mutual fund units bought on or after 1 April 2023 are taxed at your slab rate however long you hold them. When rebalancing from debt to equity, it can be cheaper to use EPF/PPF contributions or FD maturities than to redeem debt funds with large gains.
Changing allocation over time
As a goal approaches, gradually move money from equity to debt so that a late crash cannot derail it. For retirement this is often done by reducing equity by a few percentage points a year in the last decade before retirement, sometimes called a glide path. For a child's education fund due in 2032, you might start shifting from equity to short-term debt from about 2029.
The bottom line
Choose an allocation from your goals and your ability to sit through losses, write it down, and rebalance it once a year or when it drifts by more than five points. Use new money first and sell only tax-efficiently. It is unglamorous, it requires no forecasts, and it is one of the most reliable habits in investing.
Frequently asked questions
Is "100 minus age in equity" a good rule?
It is a reasonable starting point for retirement money, because it reduces equity as the time horizon shortens. But it ignores your goals, income stability and other assets. A 30-year-old saving for a house in three years should not hold 70% equity for that goal.
Should EPF and PPF count as debt?
Yes. EPF, PPF, fixed deposits, debt funds and bonds are all part of your debt allocation. Many salaried people already have a large debt allocation through EPF without realising it.
Does gold belong in a portfolio?
Gold has tended to rise when equities are under stress and when the rupee weakens, so a small allocation (often 5% to 15%) can smooth a portfolio. It produces no income and can go years without rising, so a large allocation is hard to justify.
How often should I rebalance?
Once a year is enough for most people, plus an extra check after a big market move. Rebalancing more often adds costs and taxes without a clear benefit.
Is rebalancing market timing?
No. Timing tries to predict the market. Rebalancing follows a fixed rule regardless of forecasts; it only reacts to how far the portfolio has drifted.
