Endowments vs T-bills vs Singapore Savings Bonds vs fixed deposits vs CPF top-ups

The short answer

An endowment is a life insurance policy that pays a guaranteed amount plus, in participating plans, non-guaranteed bonuses at the end of a fixed term, usually 10 to 20 years, and costs money to leave early. T-bills, Singapore Savings Bonds (SSB) and fixed deposits are short or redeemable instruments whose returns are known in advance. A CPF cash top-up is irreversible saving into the national retirement system, paid back as lifelong CPF LIFE income from 65 or later. Each answers a different question.

MoneySense warns that "Endowment products are sometimes incorrectly marketed as fixed deposits" (Understanding Endowment Insurance, 28 September 2026). The table compares general features, not particular products. Current rates for T-bills, SSB and deposits, and how to apply, are covered in detail by the sister site savings.sg; this page compares those instruments with endowments.

T-bill yields change every auction, SSB rates monthly and bank promotions without notice; check the official page before acting. The sister site savings.sg tracks T-bills, SSB and fixed deposits in more detail. The endowment row is not comparable as it stands: 4.25% and 3.00% are assumed fund returns, not the return on your premiums, and LIA states they are not limits. The comparing returns page shows how to turn an illustration into a like-for-like figure.

Guarantees and who stands behind them

The word "guaranteed" carries a different backer in each column. T-bills and SSB are Singapore Government Securities, and CPF Board states that "CPF LIFE savings are guaranteed by the Singapore Government". A fixed deposit is an obligation of the bank, insured by SDIC up to S$100,000 per depositor per member bank. An endowment's guaranteed maturity and surrender values are obligations of the insurer; if an insurer fails, the Policy Owners' Protection Scheme covers guaranteed benefits — including bonuses already declared and vested — up to S$100,000 of aggregated guaranteed surrender value per life assured per insurer, and nothing that has not yet been declared.

The second difference is how much of the outcome is fixed. A T-bill, an SSB and a fixed deposit fix the whole return at purchase; a participating endowment fixes only the guaranteed part, and the rest depends on future bonus declarations. A capital-guaranteed design guarantees that the surrender value from a stated policy year will not fall below premiums paid, subject to the policy terms — a floor, not a return. See endowment plans for how bonuses are declared.

Liquidity and the cost of leaving early

Liquidity is where the instruments differ most. An SSB can be redeemed in any month with no penalty; MAS returns principal and accrued interest, so the cost of leaving early is only the higher step-up coupons you give up. A T-bill can be sold before maturity in the secondary market, at a price that "may rise or fall" (MAS). A fixed deposit can usually be broken early, but promotional rates are generally paid only if the deposit is held to maturity, and terms vary by bank.

An endowment is built to be held to maturity. In the early years the guaranteed surrender value is typically well below premiums paid, because distribution and other costs are recovered up front; LIA's participating-policy guide warns that a policyholder who surrenders very early may "lose all or nearly all of the total premiums paid". A policy loan avoids surrender, but its interest "can be steep" (MoneySense). A CPF top-up cannot be withdrawn at all: CPF Board states that top-ups "are irreversible". Decide first how much of the sum might be needed within the term; that part belongs in redeemable or short-dated instruments.

Tax, protection and funding sources

For individuals, IRAS does not tax interest on deposits with approved banks, and MAS states that interest on Singapore Government Securities is tax exempt for individuals. Endowment premiums are excluded from life insurance relief; IRAS's treatment of maturity and surrender proceeds should be checked against its current guidance for your circumstances. CPF cash top-ups attract relief of up to S$8,000 for yourself and S$8,000 for family members each calendar year, except top-ups that attract the matching grant, all within the S$80,000 overall personal relief cap.

Funding source changes the picture. SRS money can buy T-bills, SSB, fixed deposits and single-premium insurance; SRS deposits with member banks are DI-insured, and withdrawals are taxed under SRS rules regardless of the instrument (see SRS and insurance). CPF savings can buy T-bills, and insurance only through CPFIS: single or recurring single premium, from a CPFIS-included insurer, with the member as life insured, and an endowment maturity no later than the 62nd birthday or the prescribed minimum retirement age, whichever is later (CPF Annex A). See CPF and savings plans.

Matching the tool to the job

None of the five is better in the abstract; it depends on the job the money has.

1. Emergency reserve or money needed within a year: a savings account, fixed deposit or T-bill keeps it accessible; an endowment does not.
2. Flexible medium-term savings: SSB combine a fixed schedule with monthly redemption, within the S$200,000 limit.
3. A known sum at a fixed date several years away, paid without touching it: an endowment's guaranteed maturity value may suit, provided the guaranteed-only return is acceptable on its own and early surrender is unlikely.
4. Lifetime retirement income for a Singapore citizen or PR aged 55 or over: a Retirement Account top-up raises CPF LIFE payouts; a private annuity is a layer on top — see CPF LIFE vs private annuities.
5. SRS money with a long horizon: compare instruments inside SRS on the same terms, remembering the withdrawal rules.
