Comparison of Robo-Advisor Fee Structures for SRS Investment Accounts

Singapore’s Supplementary Retirement Scheme (SRS) allows tax-advantaged saving, with 1.6 million account holders holding a combined S$172 billion as of early 2026 (Ministry of Finance). Robo-advisors have become a primary conduit for deploying these funds into diversified portfolios, yet their fee architectures remain poorly understood. The total cost difference between the cheapest and most expensive SRS-compatible robo-advisor can exceed 0.40% per annum — a gap that, on a S$100,000 investment, compounds to more than S$15,000 over two decades.

Understanding the Layers of SRS Robo-Advisor Fees

Three distinct cost layers apply to any SRS robo-advisor portfolio. First, the management fee — the platform’s headline charge, typically 0.30% to 0.80% p.a. Second, the underlying fund expense ratios of the ETFs or unit trusts held; these range from 0.03% for institutional share classes to 0.35% for niche factor funds. Third, ancillary charges such as foreign exchange spreads on non-SGD assets, custody fees, and rebalancing transaction costs. A proper comparison must sum these layers into an effective annual cost.

Endowus: Single-Fee Simplicity with Full Trailer Fee Rebates

Endowus charges a 0.60% p.a. management fee on SRS portfolios, with no platform, custody, or transaction fees. The platform rebates 100% of trailer fees from fund managers, a mechanism that reduces the effective cost of unit-trust-based portfolios. For its SRS flagship multi-asset portfolio, the underlying fund expenses average 0.12% p.a. (Endowus 2026 fee schedule). Total cost of ownership thus sits at 0.72% p.a., fully disclosed. The absence of currency conversion charges for SGD-denominated portfolios eliminates the hidden drag that plagues US-dollar-heavy strategies.

StashAway: Tiered Pricing with FX and Rebalancing Costs

StashAway applies a tiered management fee starting at 0.80% p.a. for the first S$25,000, dropping to 0.70% for the next S$25,000, and 0.60% beyond S$50,000 (StashAway 2026 pricing). Its SRS portfolios use US-listed ETFs, incurring a foreign exchange spread of 0.08% per transaction when converting SGD to USD and back. Underlying ETF expense ratios average 0.15% p.a. For a S$50,000 SRS account, the blended management fee works out to 0.75% p.a., pushing total annual costs to approximately 0.98% once the FX spread and fund costs are incorporated. Rebalancing events generate additional trading costs of roughly 0.05% per year, borne by the investor.

Syfe: Flat Fees and a 0.65% Management Charge for Equity Portfolios

Syfe’s SRS-eligible Equity100 portfolio levies a flat 0.65% p.a. management fee with no tiering (Syfe 2026 product disclosure). The portfolio holds a concentrated set of US-focused ETFs; fund-level expense ratios run at 0.07% p.a. Unlike StashAway, Syfe does not charge an explicit FX spread on the management fee portion, but currency conversion for ETF trades incurs a spread of approximately 0.10%. For a S$75,000 SRS allocation, the effective annual cost — management fee, fund expenses, and estimated FX drag — reaches 0.83% p.a.

Autowealth: Transparent, Low-Cost Fee Structure

Autowealth’s standard pricing applies to SRS accounts without modification: a 0.50% p.a. management fee and a fixed US$18 annual platform fee (Autowealth 2026 fee table). Portfolio construction uses US-listed ETFs, so currency conversion at around 0.12% per trade adds friction. Underlying fund expense ratios average 0.10% p.a. For an SRS portfolio of S$40,000, total annual costs approximate 0.72% p.a., making Autowealth highly competitive for accounts below S$500,000. The US$18 platform fee becomes negligible as assets grow, reducing the effective rate.

A 10-Year Fee Projection for a S$50,000 SRS Portfolio

Assuming a 6% p.a. gross return, the difference in fees compounds meaningfully. After 10 years, an Endowus SRS portfolio (0.72% total cost) grows to approximately S$83,500, while a StashAway portfolio at the blended 0.98% cost reaches about S$80,900. Syfe’s 0.83% cost yields roughly S$82,400, and Autowealth’s 0.72% matches Endowus at S$83,500. The S$2,600 gap between the lowest- and highest-cost option equals 5.2% of the original principal, underscoring why fee analysis deserves as much scrutiny as investment strategy when selecting an SRS robo-advisor.

Hidden Drags: Tax Withholding and Sub-Account Fees

No robo-advisor charges SRS-specific account maintenance fees, but two subtle costs persist. US-listed ETFs held in SRS accounts are subject to a 30% dividend withholding tax at the fund level, reducing the net yield of equity portfolios by roughly 0.45% p.a. compared to Ireland-domiciled alternatives (Morningstar 2026). Only Endowus currently offers SRS-accessible portfolios constructed with Irish UCITS ETFs, which face a 15% withholding rate. Additionally, some providers — though none of the four analyzed — levy a 0.05% to 0.10% p.a. “technology fee” that is not always highlighted in headline pricing. Investors must request a total cost breakdown before committing capital.

FAQ

Can I transfer my existing SRS funds into a robo-advisor without triggering tax penalties?
Yes. The SRS operator (DBS, OCBC, or UOB) permits free-of-charge transfers of SRS funds between approved institutions. A 2026 MAS guideline confirms that no withdrawal taxes or penalties apply when moving funds to a robo-advisor’s SRS account, provided the money remains within the scheme. Processing takes two to four business days.

Do robo-advisors charge a fee for SRS withdrawals upon retirement?
Robo-advisors generally do not impose redemption or closure fees on SRS accounts. However, statutory SRS rules apply: withdrawals before the prescribed retirement age are subject to a 5% penalty on the full sum and 100% of the amount is taxed as income. After the retirement age, only 50% of each withdrawal is taxable. No platform-specific exit fees were identified across the four majors in 2026.

How do SRS robo-advisor fees compare to traditional bank-distributed unit trusts?
The average expense ratio for Singapore-domiciled unit trusts with SRS eligibility is 1.65% p.a., according to Morningstar’s 2026 fee database. That figure rises to 1.80% when including front-end loads. By contrast, the four robo-advisors examined here carry all-in annual costs between 0.72% and 0.98%. On a S$100,000 investment held for 20 years at 6% gross return, the unit trust path costs an extra S$58,000 in fees relative to the cheapest robo-advisor option, net of return.
