Expense Ratio
What It Means for Singapore ETF and Fund Investors — Singapore investing guide with key metrics, examples and 2026 data.
The expense ratio is the annual fee charged by a fund or ETF, expressed as a percentage of average assets under management (AUM). It covers management fees, administration, and operating costs — deducted daily from the fund’s NAV. A lower expense ratio means more of the fund’s gross return flows to you as an investor.

What Is Expense Ratio?
Every fund — whether a unit trust, Exchange-Traded Fund (ETF), or index fund — has operating costs. Portfolio managers need to be paid, fund administration requires infrastructure, and regulatory compliance incurs costs. The expense ratio bundles all these costs into a single annual percentage figure deducted directly from the fund’s assets, reducing the net asset value (NAV) you see as an investor.
Crucially, the expense ratio is not charged separately from your account — it is embedded in the fund’s daily pricing. If a fund reports a 6% annual return but has an expense ratio of 1.5%, your net return is approximately 4.5%. The deduction happens automatically, which is why many investors underestimate its long-term impact.
The expense ratio is also known as the Total Expense Ratio (TER) or Management Expense Ratio (MER) in some markets. In Singapore’s unit trust market, funds sold through platforms like FSMOne or robo-advisors typically disclose the TER in their fund factsheets as required by MAS regulations.
How It Works
Expense ratios vary dramatically by fund type. Passive ETFs: 0.03-0.30% p.a. (very low; replicating an index requires minimal active management). Active unit trusts: 1.0-2.5% p.a. (higher; fund manager research and trading cost more). Robo-advisor portfolios: 0.20-0.80% p.a. platform fee on top of underlying ETF expenses.
For Singapore-listed ETFs on SGX, common expense ratios include: Nikko AM STI ETF: 0.30% p.a.; SPDR Straits Times Index ETF: 0.30% p.a.; Lion-Phillip S-REIT ETF: 0.60% p.a.; Vanguard FTSE All-World UCITS ETF (VWRA): 0.22% p.a. (LSE-listed, accessible via FSMOne).
The compounding effect of expense ratios is striking over long horizons: S$100,000 invested at 7% gross return for 30 years grows to S$761,000. The same at net 5.5% (after 1.5% TER) grows to only S$499,000 — a S$262,000 difference entirely from fees.
Expense Ratio in Singapore
In Singapore, retail investors access funds through several channels, each with different expense ratio implications. Under the CPF Investment Scheme (CPFIS), MAS and CPF Board cap expense ratios on CPFIS-eligible unit trusts at 1.75% p.a. for equity funds and 1% for fixed income funds — protecting CPF investors from high-fee products. Even at 1.75%, a CPFIS unit trust must generate returns well above the risk-free CPF OA rate of 2.5% to justify the cost.
SRS-eligible funds have no expense ratio caps, so investors must evaluate costs independently. Robo-advisors like Endowus and Syfe charge platform fees on top of underlying ETF expense ratios. Endowus passes through management fee rebates (trailer fees), which can significantly reduce the effective all-in expense ratio to near-institutional rates.
Always look at the all-in cost when comparing robo-advisors and unit trusts in Singapore. The advertised management fee is often lower than the full TER.
Real-World Examples
Compare two Singapore investors both starting with S$50,000 at age 30. Investor A puts money in an active Singapore unit trust with a 1.8% expense ratio earning 7% gross returns. Net return: 5.2% p.a. By age 65: portfolio grows to approximately S$290,000. Investor B invests in a passive ETF with 0.30% expense ratio at the same 7% gross return. Net return: 6.7% p.a. By age 65: portfolio grows to approximately S$480,000 — S$190,000 more, entirely due to lower fees.
As at Q1 2026, the Nikko AM STI ETF (SGX: G3B) is one of Singapore’s most popular low-cost ETFs, with a 0.30% p.a. expense ratio, providing exposure to Singapore’s top 30 companies including DBS, OCBC, UOB, Singtel and CapitaLand Integrated Commercial Trust.
Why It Matters for Investors
Expense ratio awareness is one of the highest-leverage financial literacy skills for Singapore retail investors. You cannot control market returns, but you can control the fees you pay — minimising expense ratios is one of the few reliable ways to improve long-term portfolio outcomes.
When evaluating any fund on FSMOne or any robo-advisor, always check the full TER in the fund factsheet — not just the advertised management fee, which may exclude fund administration and custody costs. Also check whether the platform charges a separate advisory fee on top of the fund TER.
For CPFIS investors, the MAS expense ratio cap provides baseline protection, but the best strategy is often to prioritise low-cost CPFIS-eligible ETFs over actively managed funds. Use our Dividend Yield Calculator and explore our Best S-REITs 2026 guide as cost-effective income alternatives.
Frequently Asked Questions
What is a good expense ratio for an ETF in Singapore?
For passive ETFs, a good expense ratio is below 0.50% p.a. The best global ETFs (Vanguard, iShares) charge 0.03-0.22% p.a. Singapore-listed ETFs like the Nikko AM STI ETF charge 0.30% p.a. For unit trusts, look for TERs below 1% p.a. — anything above 1.5% erodes returns significantly over a 20-30 year investment horizon.
Is the expense ratio charged yearly in Singapore?
Yes, the expense ratio is an annual charge applied daily as a fraction of the fund’s NAV. It is not a separate invoice — it is embedded in the fund’s daily pricing, meaning the NAV you see already reflects the expense ratio deduction. The annual fee reduces total fund assets, lowering NAV slightly relative to gross returns.
Does CPFIS have an expense ratio cap?
Yes. MAS and CPF Board cap expense ratios on CPFIS-eligible unit trusts at 1.75% p.a. for equity funds and 1.00% p.a. for bond funds. This protects CPF investors from high-fee products. ETFs accessible through CPFIS do not have this cap but tend to have lower fees naturally.
What is the difference between expense ratio and management fee?
The management fee is paid specifically to the fund manager for portfolio management. The expense ratio (Total Expense Ratio/TER) is broader — it includes the management fee plus administrative costs, custodian fees, audit fees, and other operational costs. Always compare TERs rather than management fees alone for a true cost picture.
Do robo-advisors in Singapore charge expense ratios?
Robo-advisors like Endowus and Syfe charge a platform or advisory fee (typically 0.25-0.65% p.a.) on top of the underlying fund’s expense ratios. The all-in cost (platform fee + fund TER) is the relevant figure. Endowus rebates trailer fees back to investors, which can reduce the effective all-in cost significantly versus buying through traditional bank channels.
