You want your money to work harder. But every dollar paid in fees is a dollar that stops compounding for you. In Singapore, the difference between a 0.2% expense ratio and a 1.5% one can cost you six figures over a 30 year investing career. That is why finding the best low cost index funds Singapore 2026 has to offer is one of the smartest moves you can make.
The best low cost index funds Singapore 2026 are dominated by a handful of globally diversified ETFs and unit trusts with expense ratios under 0.30%. By combining a low cost brokerage like Interactive Brokers or a robo advisor like Endowus with funds tracking the S&P 500, developed world bonds, or a global equity index, you can build a world class portfolio for less than the cost of a kopi a day.
Why Low Cost Index Funds Matter More Than Ever
A 2025 study from Morningstar showed that fees were the single best predictor of future returns for passive investors. The logic is simple. An index fund that tracks the market will deliver the market return minus its fees. If the market returns 7% a year, a fund with a 0.10% fee gives you 6.90%. A fund with a 1.00% fee gives you 6.00%. Over 30 years on a $50,000 starting portfolio with $500 monthly contributions, that 0.90% gap costs you over $120,000 in missed growth.
For Singapore based investors, the challenge is that many local unit trusts carry expense ratios above 1%. The good news is that you have more low cost options in 2026 than ever before.

How to Buy These Funds From Singapore
You cannot just walk into any bank and get these low fees. The process matters. Here is a numbered list showing the steps to set yourself up.
- Open a brokerage account that gives you access to low cost ETFs. For UCITS ETFs (the European listed ones), Interactive Brokers (IBKR) is the most popular choice. For local unit trusts, a CPF Investment Account with a low cost provider like Endowus or FSMOne works well.
- Fund your account. For IBKR, deposit at least SGD 2,000 to avoid monthly inactivity fees. For Endowus, there is no minimum for cash based accounts.
- Choose your core fund. Most experts recommend starting with a single globally diversified fund like the Amundi Index MSCI World (available on Endowus) or the iShares Core S&P 500 UCITS ETF (available on IBKR).
- Set up a recurring buy. On IBKR, you can schedule a monthly purchase of your chosen ETF. On Endowus, you can automate a monthly investment into your chosen fund.
- Ignore it. Check your portfolio once a quarter at most. Tinkering leads to trading costs and emotional mistakes.
What to Look for in a Low Cost Fund
Not every cheap fund is a good fund. You need to check three things.
- Total Expense Ratio (TER). This is the fee that comes out of your returns every year. Aim for under 0.30%. Many of the best low cost index funds Singapore 2026 offer rates well below that.
- Tracking error. A fund that claims to track the S&P 500 but lags behind by 0.5% every year is not doing its job. Check the fund factsheet for past performance vs benchmark.
- Liquidity. Some unit trusts have high minimum holding periods or exit fees. ETFs trade like stocks, so you can sell them any day the market is open.
A rule of thumb from John C. Bogle, the founder of Vanguard: “The best investment you can make is to minimize the cost of investing. Costs matter over the long term. They are the only thing you can control.”
The Trade Off Between Unit Trusts and ETFs
Both options have pros and cons. Here is a bulleted list to help you decide.
- Unit trusts (like those from Lion Global Invest and Nikko AM) let you buy fractional shares. You can invest $100 and own a piece of the fund. They also allow CPF and SRS investing.
- ETFs (like the iShares S&P 500 UCITS) trade on exchanges. You need to buy whole shares, and you pay brokerage commissions. But the expense ratios are often lower, and you can trade them on global markets.
- For most investors starting with less than $10,000, a unit trust through a low fee platform like Endowus is the better choice. The convenience and fractional ownership outweigh the tiny fee difference.
- For investors with more than $10,000, buying the UCITS ETF directly on Interactive Brokers can shave another 0.05% to 0.10% off your fees.
Common Mistakes to Avoid When Picking Low Cost Funds
Even experienced investors make errors here. Here is a table of the most common pitfalls.
| Mistake | Why It Hurts You | Better Approach |
|---|---|---|
| Chasing the lowest fee without checking the benchmark | A fund tracking a narrow index may be cheap but not diversified | Pick a fund that covers the whole global market, like the MSCI World |
| Buying multiple overlapping funds | You end up with 5 funds that all own Apple and Microsoft stock | Stick to one or two funds: one global equity and one bond fund |
| Ignoring FX and brokerage fees | A 0.07% ETF fee means nothing if you pay 1% to convert SGD to USD every month | Use SGD denominated funds or platforms that offer zero commission FX |
| Forgetting CPF and SRS eligibility | Some cheap UCITS ETFs cannot be held in your CPF Investment Account | Check eligibility before buying. Lion Global Invest funds are CPF eligible |

Taking Action on Your Investment Plan
Knowing which funds are best is only half the battle. You also need to decide where to hold them. If you are using your Supplementary Retirement Scheme (SRS) account, you can buy unit trusts that are SRS eligible. If you are investing cash, the UCITS ETFs on Interactive Brokers give you the lowest fees. And if you want a hands off approach, a robo advisor like Endowus or Syfe will build a low cost portfolio for you using the exact same funds listed above.
