How to Invest in the ASX 200
Want exposure to Australia's 200 biggest companies? How to invest in the ASX 200 simply and cheaply, without picking a single stock.
By Timothy Hirou GaschereauPublished 8 min read
The ASX 200 is Australia's benchmark index of the 200 largest listed companies. You cannot buy the index itself; you buy a low-cost fund that tracks it. This guide covers the main options, how to actually invest step by step, and the pros and cons worth understanding first.
🎯 The essential: The ASX 200 tracks Australia's 200 biggest listed companies. You get exposure through an ETF that tracks it: the main options are IOZ (about 0.05%), A200 (about 0.04%), VAS (0.07%, actually the ASX 300) and STW. To invest, open a broker, fund it, search the ticker and place a buy order. It is low-cost and diversified, but heavily concentrated in banks and miners, so most long-term investors pair it with a global share fund.
What is the ASX 200?
The S&P/ASX 200 tracks the 200 largest companies on the ASX, weighted by float-adjusted market value, and covers roughly 80% of Australia's total listed market. When people say "the market is up 1% today", they usually mean the ASX 200. It is heavily weighted to two sectors: financials (the big four banks and others) and materials (BHP, Rio Tinto, Fortescue and other miners), which together often make up around half the index.
For the full detail on how the index works, see our guide to what the ASX 200 is.
You cannot buy the index directly: you buy a fund that tracks it
The ASX 200 is an index, not a product. You buy a fund designed to replicate its returns. There are two vehicles: ETFs, which are ASX-listed and trade like shares through a broker (the practical route for most people), and index managed funds, bought directly from a provider like Vanguard, which suit investing a set dollar amount each month without worrying about brokerage. For most beginners, ETFs are simpler. See the best ETFs in Australia for context.
The main ASX 200 (and ASX 300) index ETFs
Four ETFs cover most Australians' ASX 200 exposure. Three track the ASX 200 directly; VAS tracks the slightly broader ASX 300.
| ETF | Tracks | MER | Notes |
|---|---|---|---|
| IOZ | S&P/ASX 200 | ~0.05% p.a. | iShares. Low-cost, highly liquid |
| A200 | Solactive Australia 200 | ~0.04% p.a. | Betashares. Cheapest, near-identical holdings |
| VAS | S&P/ASX 300 | 0.07% p.a. | Vanguard. Adds ~100 small caps. Very popular |
| STW | S&P/ASX 200 | ~0.13% p.a. | SPDR. The oldest ASX ETF, higher fee |
IOZ, A200 and VAS all hold essentially the same large companies and behave almost identically. A200 uses a Solactive index rather than S&P, but the holdings are near-identical, and VAS's extra 100 small caps make little difference day to day. See our guides to A200 and VAS.
How to actually invest, step by step
- Open a brokerage account. You need an online broker (CommSec, Stake, Pearler, SelfWealth). Compare fees first; see how to buy shares in Australia.
- Verify your identity. A standard 100-point ID check, usually a few minutes online.
- Fund your account by bank transfer (typically one to two business days).
- Search the ticker (IOZ, A200, VAS or STW) to see the price and details.
- Choose an order type. A market order fills at the current price; a limit order sets your maximum but may not fill straight away.
- Place the order and confirm. Your units appear once the order settles (T+2).
The pros of an ASX 200 index fund
- Low cost. Fees start around 0.04%, so about $4 a year on $10,000.
- Instant diversification. One purchase gives you 200 companies across many sectors, no stock-picking.
- Franking credits. Australian dividends carry tax credits that can cut your tax bill or generate a refund.
- Simplicity and liquidity. Buy it, hold it, reinvest the dividends. ASX 200 ETFs are among the most traded securities on the ASX.
The cons and things to know
- Concentration in financials and materials. The top holdings can be 40% or more of the fund, so a bad run for banks or miners hits the whole thing.
- Home-country bias. Australia is roughly 2% of the global sharemarket, so an ASX-only portfolio misses the other 98%.
- No international exposure. Zero Apple, Microsoft, LVMH or Samsung. If global markets outperform, your returns lag.
- Tied to the Australian economy. A China slowdown or a domestic downturn can weigh on the index.
None of these are reasons to avoid an ASX 200 fund. They are reasons to understand what you own.
Should you add global shares too?
Most index-fund advocates suggest pairing Australian shares with a global fund: you keep the Australian dividends and franking credits, and add the rest of the world's growth. The most popular global ETF here is VGS (1,500-plus companies across developed markets). A simple two-fund portfolio of VAS (or A200) plus VGS covers both bases. There is no single right split; 50/50 or 70/30 Australian/global are common starting points, but your circumstances and goals matter.
How much does it cost?
The main cost is the MER, deducted automatically from the fund: about $4 a year on $10,000 for A200, $5 for IOZ, $7 for VAS and $13 for STW. On top of that, brokerage (from $0 to around $10 per trade) applies each time you buy or sell, which matters most for small, regular investments. A tiny bid-ask spread also applies, though it is very small on liquid funds like IOZ and VAS. There are no entry, exit or performance fees.
You get ASX 200 exposure by buying a tracking ETF (IOZ, A200 or VAS are the low-cost favourites), not the index itself. It is cheap, diversified and simple, with franking credits as a local bonus, but it is concentrated in banks and miners and holds no international shares. That is why most long-term investors pair it with a global fund like VGS.
❓ Frequently asked questions
What is the best ASX 200 ETF?
+
There is no single best answer, but IOZ and A200 are the most cost-competitive at around 0.05% and 0.04% p.a. respectively. VAS is the most popular by funds under management and covers the ASX 300 for slightly broader exposure. STW is the oldest ASX ETF but carries a higher fee. For most investors, the difference between IOZ, A200 and VAS is negligible; pick one and stick with it.
Can I buy the ASX 200 directly?
+
No. The ASX 200 is an index, not a product, so you cannot buy it directly. What you can buy is an ETF or index managed fund designed to track the index's performance as closely as possible.
How much do I need to invest in the ASX 200?
+
The minimum is roughly the price of one unit, typically $50 to $150 depending on the ETF and current price. Some brokers apply the ASX minimum of $500 for a first parcel. There is no ongoing minimum once you hold units.
Does an ASX 200 ETF pay dividends?
+
Yes. ASX 200 ETFs distribute income (called distributions) quarterly or half-yearly depending on the fund. Australian company dividends often carry franking credits, which can reduce your tax bill or generate a refund depending on your income.
Is the ASX 200 a good investment?
+
Historically the ASX 200 has delivered strong long-term returns when dividends are reinvested, though past performance does not guarantee future results. The main things to understand are the heavy concentration in financials and materials, and the lack of international exposure. For many long-term investors it forms a solid core, especially when paired with global shares.
What is the difference between IOZ, A200 and VAS?
+
IOZ tracks the S&P/ASX 200 (iShares). A200 tracks the Solactive Australia 200 (Betashares), holding virtually the same companies under a different index provider. VAS tracks the broader S&P/ASX 300 (Vanguard), adding around 100 smaller companies. In practice all three behave very similarly and the cost differences are tiny.
