One of the most important investment decisions you will make is how to divide your money between different asset classes. The right asset allocation strategy evolves over time, balancing long-term growth in earlier years with greater capital protection as retirement approaches — this sits within a broader framework where you can explore how investment strategies are structured in practice.
This guide breaks down age-appropriate asset mixes, explains why your time horizon matters, and shows you how to adjust for your own goals and risk tolerance. Whether you are in your 20s building wealth or in your 60s preparing for regular withdrawals, you will find concrete ranges to guide your thinking.
Quick Answer: Age-Based Asset Allocation Snapshots
These are general educational guidelines to help you understand typical allocation patterns. They are not personal financial advice, and your individual circumstances will shape the right mix for you.
Here are example asset allocation models by life stage:
Teens and early 20s:
90–100% growth assets (shares, diversified equity ETFs)
0–10% defensive assets (bonds, cash)
Late 20s to 30s:
80–90% growth assets
10–20% defensive assets
40s:
60–80% growth assets
20–40% defensive assets
50s:
40–60% growth assets
40–60% defensive assets
60s:
30–50% growth assets
50–70% defensive assets
70s and beyond:
20–40% growth assets
60–80% defensive assets
Growth assets include Australian and global shares, listed property, and diversified growth funds. Defensive assets include investment-grade bonds, government bonds, corporate bonds, term deposits, and savings accounts.
These snapshots serve as starting points. Your actual allocation should reflect your risk level, income sources, tax situation, and financial goals. Before making significant changes to your investments, consider speaking with a licensed financial adviser who can provide financial advice tailored to your situation.
Understanding Asset Allocation and Why Age Matters
Asset allocation is the process of dividing your investment portfolio across various asset classes—primarily growth assets like shares and property versus defensive assets like bonds and cash. This mix determines both your growth potential and your exposure to market volatility and forms the foundation of building a structured investment portfolio aligned with your financial goals.
Age influences your allocation through several key factors:
Time horizon: A 25-year-old has 30+ years for money invested to compound and recover from market downturns. A 60-year-old may have only 5–10 years before drawing on those funds. This highlights the importance of maintaining discipline — especially when considering how to stay invested during market volatility.
Recovery capacity: While still working, you can ride out market swings and even buy more at lower prices. After retirement, market downturns during withdrawals can permanently damage your financial future.
Income needs: Later life often demands steady, reliable income and capital protection rather than maximum growth.
Growth assets have historically delivered returns of 7–10% annually for global equities but come with higher risk. During the 2008 financial crisis, the stock market dropped nearly 50%. Defensive assets like government bonds and term deposits offer lower returns (typically 2–5%) with minimal volatility.
Younger investors can often tolerate portfolios of mostly stocks because they have several decades for recovery. Older investors typically shift toward capital preservation, accepting lower returns to manage risk more conservatively.
Age is only a starting point. Your life stage—whether you are a business owner, new parent, or approaching retirement—and your investment goals also drive the right allocation.
General Rules of Thumb for Asset Allocation by Age
Several well-known rules of thumb offer quick guidance on how much risk you might take at different ages. These formulas are rough guides rather than prescriptions.
The Classic “100 Minus Age” Rule
Subtract your age from 100 to find your target percentage in shares. The remainder goes to bonds and cash.
Age | Shares | Bonds/Cash |
|---|---|---|
25 | 75% | 25% |
40 | 60% | 40% |
55 | 45% | 55% |
70 | 30% | 70% |
Modern Adaptations
Longer lifespans and lower bond yields have prompted updated versions:
110 minus age: Adds 10% more to shares, reflecting that retirements may last 25–35 years
120 minus age: Even more aggressive, suitable when planning for a 30-year retirement period
Using “120 minus age,” a 30-year-old would hold 90% in growth assets, while a 70-year-old would still maintain 50% in shares.
When to Adjust These Rules
These formulas need modification for:
Very conservative or aggressive risk preferences
Non-portfolio assets such as investment properties or business ownership that add concentration risk
Planning for retirement spanning several decades
Individual circumstances like job stability or health considerations
Treat these as starting points to adapt. Money Path focuses on structured, goal-based planning rather than relying solely on simple age formulas.
Asset Allocation in Your Teens and 20s
Starting early is powerful. With 40+ years until retirement, your money has maximum time to compound. A $10,000 investment at 7% annual returns grows to approximately $150,000 over 40 years—compared to just $38,000 over 20 years.
Typical Allocation for Long-Term Investors
For someone investing toward retirement 40+ years away, a common educational example is:
90–100% growth assets (low-cost Australian and global equity index funds or ETFs)
0–10% defensive assets (high-interest savings accounts or short-term bond funds) as a small stabiliser
What to Focus On
This stage is about building good habits:
Regular contributions: Automate investing from each pay to build discipline
Broad diversification: Focus on market-wide funds rather than picking individual stocks
Separate emergency fund: Keep 3–6 months of expenses in cash, separate from long-term investments
Understanding the Trade-Offs
Large short-term falls are normal with this allocation. A 30–50% drop during major market downturns can feel alarming, but historical data shows that diversified portfolios have recovered fully over longer periods. The 2008 crash, for instance, saw global equities fully recover by 2013.
If you have unstable income from casual work or an early-stage business, you might keep a slightly higher cash buffer. However, your long-term investments should remain growth-oriented to capture the equity premium over several decades.
Asset Allocation in Your 30s
Many investors in their 30s balance long term growth with growing responsibilities. Mortgages, children, and career development all compete for attention and resources.
Example Allocation Range
For a typical 30-something investing toward retirement 25–35 years away:
80–90% growth assets (equities and property)
10–20% defensive assets (bonds and cash)
How to Structure This in Practice
Use diversified equity funds spanning Australian and global markets
Add a core bond fund or term deposits for the defensive portion
Maintain a separate emergency fund (3–6 months of expenses) outside your investment portfolio
Key Trade-Offs
Growth focus: Sustaining higher risk tolerance allows you to pursue long-term goals like retirement or your child’s education, where you need returns exceeding inflation.
Defensive cushion: Holding enough in bonds and cash prevents panic-selling during 20–30% market corrections.
When to Review
Major life events trigger natural reassessment points:
Buying a home
Having children
Changing careers
Starting a business
Adjust your asset mix as your financial situation evolves, but avoid making dramatic changes based on short-term market conditions. These decisions often overlap with questions such as whether to prioritise investing or paying down debt.
Asset Allocation in Your 40s and 50s
These are typically peak earning years. You have built substantial wealth, but protecting what you have becomes increasingly important as retirement approaches.
Typical Allocation Ranges
Age Group | Growth | Defensive |
|---|---|---|
40s | 60–80% | 20–40% |
50s | 40–60% | 40–60% |
The exact split depends on your planned retirement age and how much risk you are comfortable taking. This also ties into broader decisions around how much to allocate between shares and cash at different stages.
What This Looks Like in Practice
Core growth: Diversified share funds across Australian and global markets
Increased stability: Quality bond funds, term deposits, and cash holdings
Income orientation: Dividend-focused funds or balanced funds as retirement nears
Key Priorities
Sequence risk management: A major downturn immediately before retirement can cut sustainable withdrawal rates significantly. Reducing growth exposure protects against this.
Maximise contributions: Take advantage of higher income to boost superannuation. In 2026, contribution limits allow significant catch-up for those over 50.
Simplify structures: Consolidate into fewer, broader funds to make future income management easier.
Planning Your Transition
Map your desired retirement date and estimate remaining investment years. Phase your shift from aggressive to balanced allocations gradually rather than making abrupt changes.
Asset Allocation in Your 60s and in Retirement
The focus shifts from building wealth to funding regular withdrawals while protecting your principal amount. You need to balance generating income for current expenses against maintaining growth potential for inflation protection over a retirement that may last 25–30 years. This becomes particularly relevant when considering how to structure income withdrawals in retirement.
Example Allocation Ranges
Stage | Growth | Defensive |
|---|---|---|
Early 60s (still working) | 40–60% | 40–60% |
In retirement | 30–50% | 50–70% |
Key Objectives
Ensure enough defensive assets to cover several years of planned withdrawals
Maintain meaningful growth exposure to hedge against 3% annual inflation erosion
Create reliable income streams to supplement other sources
The Bucket Strategy
A practical approach divides your portfolio into time-based buckets:
Short-term bucket (0–3 years of spending):
Cash and term deposits
Money market instruments
Current yields around 4–5%
Medium-term bucket (3–7 years):
Investment-grade bonds and income funds
Provides stability with modest growth
Long-term bucket (7+ years):
Diversified equities
Captures future income and inflation protection
Adjusting for Other Income
Retirees with secure income sources like defined benefit pensions or rental income may tolerate higher growth allocations. Those relying mostly on portfolio withdrawals should lean more conservative to avoid risk losing capital during extended market downturns.
How to Tailor Your Allocation Beyond Age Alone
Age-based guides provide a starting point, but your actual allocation should reflect personal factors that simple formulas cannot capture.
Factors That Justify Modifying the Standard Mix
Risk tolerance: Your comfort with volatility and potential losses. Someone with higher risk tolerance might add 10–20% more to growth assets.
Job security: Unstable income warrants more defensive holdings or a larger emergency fund.
Debt levels: High mortgage or business loans may suggest a more conservative approach.
Other assets: Investment properties or business ownership create concentration in one asset class, potentially justifying more diversification in your liquid portfolio.
Future income expectations: Anticipated inheritances or career advancement might affect how much risk you can accept.
The Sleep-at-Night Test
If market fluctuations keep you awake, you may need more defensive holdings regardless of age. Past performance shows that investors who panic-sell during downturns often lock in losses and miss recoveries.
Natural Reassessment Points
Major life events should trigger allocation reviews:
Marriage or divorce
Selling a business
Health changes
Receiving an inheritance
Using Target Ranges
Rather than targeting a single number (like 70% growth), consider working with ranges (60–70% growth). This provides flexibility and makes adjustments more manageable over time.
Building and Maintaining an Age-Appropriate Portfolio
Having the right allocation is only valuable if you implement it clearly and maintain it over time. Many investors set an initial mix then neglect regular maintenance.
Choosing Investments to Match Your Allocation
For growth assets:
Diversified, low-cost index funds or ETFs across Australian and global shares
Avoid over-concentrating in a single share, sector, or country (limit individual positions to 5–10% of the portfolio)
For defensive assets:
High-quality bond funds or balanced funds
Term deposits and high-interest savings accounts
Money market securities for the most conservative portion
The Importance of Rebalancing
Market movements naturally shift your allocation. If shares outperform, you may end up with more growth exposure than intended.
Review your portfolio regularly:
Check at least once or twice per year
Rebalance after significant market swings
How to rebalance:
Sell some of what has grown beyond target
Add to underweight positions
Use new contributions and dividends to rebalance gradually, minimising trading costs
Practical Considerations
Tax efficiency: In taxable accounts, consider tax implications before selling. In retirement accounts, rebalancing is typically tax-neutral.
Gradual transitions: Adjust allocation slowly through life stages rather than making dramatic shifts
Tracking: Use a simple spreadsheet or platform tools to monitor whether your current portfolio still aligns with your goals
Discipline in maintaining your target mix—rather than trying to time market conditions—has historically added 0.5–1% annually to returns. This reinforces the importance of knowing when and how to rebalance your portfolio effectively.

FAQs: Asset Allocation by Age
Common questions about adjusting your asset mix as you age.
What is the best asset allocation for my age?
There is no single “best” allocation. Typical ranges by decade (20s: 90% growth; 60s: 40% growth) provide starting points, but you must adapt based on your goals and risk tolerance, financial situation, and time horizon.
Should I change my investments just because I had a birthday?
No. Allocation changes should be gradual and tied to meaningful shifts in your time horizon or life stage—not triggered by every birthday. Review portfolio periodically, perhaps annually, and adjust as circumstances genuinely change.
Is the “100 minus age” rule still relevant?
It remains a useful starting point but may be too conservative given modern life expectancy. Many planners now suggest “110 minus age” or “120 minus age” to ensure adequate growth over longer retirements. Your other assets and personal comfort with risk should also influence your decision.
How often should I rebalance my portfolio?
Review once or twice per year, or after large market moves (10% or more drift from targets). Where possible, use new contributions or dividend reinvestment to rebalance gradually, reducing trading costs and tax implications.
What if I’m behind on retirement savings for my age?
Consider these steps:
Increase your savings rate to 15–20% if possible
Explore delaying retirement by a few years
Review spending to free up additional funds
Carefully consider whether a higher growth allocation suits your risk profile—but only if you can genuinely tolerate market swings
Is it ever too late to invest in shares?
No. Even in your 60s and 70s, maintaining 20–50% in growth assets helps manage inflation risk over a retirement that may span 25–30 years. However, allocations should remain conservative and aligned with your spending needs and ability to weather market downturns.
How does my home or investment property affect my asset allocation?
Large property exposure creates concentration in one asset class. If your home or investment property represents significant wealth, your liquid portfolio may need more diversification across other asset classes to manage overall risk. A $500,000 property investment, for example, might justify reducing equity exposure in your share portfolio by 10% or more.
Key Takeaways
Asset allocation should evolve with your age, shifting from growth-focused to more defensive as retirement approaches
Rules of thumb like “100 minus age” are starting points, not prescriptions
Your personal risk tolerance, other assets, and financial freedom goals should shape your actual mix
Rebalance portfolio regularly to maintain your target allocation
Even older investors benefit from some growth exposure to combat inflation over extended retirements
Your investment decision about asset allocation is one of the most powerful factors in achieving financial freedom. Start with age-appropriate guidelines, then refine based on your individual circumstances. Money Path’s tools can help you model different scenarios and build a plan that keeps your portfolio aligned with your evolving goals.
