Mercer Super's SmartPath default adjusts investments with age. Its range also includes ready-made portfolios, passive and sustainable choices, and direct investing in eligible plans.
Individuals can join Mercer SmartSuper, or employees can join their employer's Mercer plan. Access to particular investments and insurance features depends on the plan.

MLC's MasterKey range includes employer, personal and Super & Pension Fundamentals accounts. The investment and insurance terms depend on which product you hold.
MasterKey Super Fundamentals is designed for individual members. Business Super is arranged through employers, and employer discounts or insurance subsidies can affect the comparison.

Source: APRA Comprehensive Product Performance Package 2026, published 28 August 2026. Fees reflect the reporting year to 30 June 2026, are net of tax, use standard arrangements and exclude member-activity fees. Dollar figures are rounded. They are not a current quote. Check the latest PDS for changes, insurance premiums and any separately charged advice.
Returns are annualised historical results. Different return bases, risk levels and periods cannot be treated as interchangeable. MySuper net returns use a $50,000 representative balance even when you change the fee balance. A lifecycle stage return does not track a person moving between stages. Missing figures mean not reported, not zero. Past returns do not predict future returns. Read our method and APRA's definitions.
| What to compare | Mercer Super | MLC |
|---|---|---|
| Membership and access | Individuals can join Mercer SmartSuper, or employees can join their employer's Mercer plan. Access to particular investments and insurance features depends on the plan. Sources1 | MasterKey Super Fundamentals is designed for individual members. Business Super is arranged through employers, and employer discounts or insurance subsidies can affect the comparison. Sources24 |
| Accounts and products | Mercer SmartSuper and Mercer Super Trust employer plans. Virgin Money and restricted employer MySuper products need separate labels. Mercer SmartSuper Mercer employer plans Mercer SmartRetirement Income Mercer Direct where available Sources14 | MLC MasterKey products in MLC Super Fund. Expand, Plum and NAB-specific plans are separate product propositions. MLC MasterKey Business Super MLC MasterKey Personal Super MLC MasterKey Super and Pension Fundamentals MLC MySuper Sources17 |
| Investment choices | Mercer SmartPath, subject to the employer plan's own product. SmartPath gradually changes the investment mix as members age. Ready-made options let members choose a risk level without assembling every asset class. Select-Your-Own includes sector, passive and sustainable options. Mercer Direct provides selected shares, ETFs and term deposits where the plan permits it. Sources2 | MLC MySuper for eligible MasterKey Business and Personal Super members; check the selected investment in Fundamentals. MasterKey Super Fundamentals offers ready-made choices, lower-cost and socially responsible portfolios, plus asset-class options for a member-built portfolio. MLC MySuper invests across mainstream asset classes with some private and alternative assets and uses active and passive managers. Sources23 |
| Insurance | Most Mercer Super Trust members have group insurance through AIA Australia, but the fund says the applicable plan determines the cover. Obtain the employer-plan insurance document and compare benefits, exclusions and subsidies before moving to another account. Sources5 | The insurance offer differs between Business, Personal and Fundamentals accounts. Business and Personal Super can include both an insurer premium and an insurance administration fee; Fundamentals insurance charges consist of the insurer premium. Check the applicable guide rather than assuming all MLC insurance is priced the same way. Sources47 |
| Retirement income | Mercer SmartRetirement Income offers allocated pensions. Its Smart Bundle combines a SmartPath investment strategy with preselected pension payments and timing, which members can change. It is still an allocated pension arrangement, so it should not be described as a guaranteed income for life. Sources34 | MasterKey Pension Fundamentals provides account-based and transition-to-retirement pension pathways. A member can assess the pension menu as part of planning a move into retirement, but the pension fee schedule must be checked separately. Sources67 |
| Advice and support | Mercer's product information directs members to obtain advice appropriate to their circumstances. This research has not verified a single free personal-advice entitlement for every Mercer plan; ask the fund for the available service and fee. Sources5 | Members can use MLC without a financial adviser. If they engage an adviser, fees for super-related advice may be deducted with consent and subject to product rules. Advice fees should be included in the overall cost of an advised arrangement. Sources4 |
| Fee details to check | Compare the actual plan fee schedule, including any employer subsidy or negotiated discount. The cost also depends on SmartPath cohort or chosen investments. Mercer Direct and its underlying investments can carry additional charges. Sources123456 | An employer may have negotiated reduced fees, shown in the plan's Features At A Glance document. Changes from 1 April 2026 removed the insurance-fee cap for affected Business and Personal Super members and reduced the cap on the percentage administration fee. These are distinct changes: lower administration fees do not necessarily mean a lower total cost for an insured member. Sources45 |
| Comparing investment performance | A quoted SmartPath result belongs to a particular cohort and period. Mercer sometimes illustrates returns using one of its largest groups of members; that is not a single return received by everyone. Use the same age, product and fee basis in the competing account. Do not apply Mercer SmartSuper figures to Virgin Money or every employer plan in the same legal fund. Treat the sustainable-options judgment as a dated finding about specified claims and options. Sources2 | Compare the exact MySuper portfolio or chosen MasterKey investment. Age and product matter, and a return from one underlying fund is not the return from an entire member account after every administration, insurance and advice charge. Show the MasterKey product name and employer discount assumptions. Separate insurance premium, insurance administration charge and adviser fee where relevant. Sources1234567 |
THE SUPERGURU VIEW
Mercer's appeal depends heavily on the employer plan. A plan with useful insurance or negotiated fees can look quite different from the standard public product. SmartPath offers a convenient default, while the retirement bundle may reduce setup decisions, provided the chosen payment rate fits the retiree's spending needs.

THE SUPERGURU VIEW
MLC deserves an account-level review rather than a verdict based on the brand. The breadth of investments can help someone with a deliberate portfolio, while a workplace subsidy may change the price materially. For current members, the 2026 insurance-fee-cap change is a practical reason to check the statement.

Use the membership rules to establish which accounts are available to you. Then compare the total price of the investment option and cover you need. A lower fee or higher historical return alone does not tell you which fund is suitable.
Ask both funds to confirm insurance acceptance, exclusions, waiting periods and whether cover would change when you leave your employer. Obtain advice before giving up a defined benefit or an insurance policy you may not be able to replace. ASIC Moneysmart explains the comparison checks.
