Non-Guaranteed Bonus (Insurance) Singapore

Why the extra return quoted on your endowment or whole life plan isn’t promised

A non-guaranteed bonus is the portion of a participating (par) insurance policy’s projected payout — whether an endowment, whole life plan, or annuity — that depends on the insurer’s actual investment and business performance, rather than being contractually promised at purchase.

Key Takeaways

  • Non-guaranteed bonuses come in two forms: reversionary bonuses (declared periodically and, once vested, generally become guaranteed) and terminal bonuses (paid only at maturity, surrender, or claim, and never guaranteed until then).
  • MAS requires insurers to illustrate non-guaranteed benefits using two standardised rates (currently up to 3.00% and 4.75% p.a.) so consumers can compare across insurers on a like-for-like basis.
  • The actual bonus paid depends on how the insurer’s participating fund performs against the assumptions used when the policy was priced.
  • A policy illustration showing an attractive total return can still fall short in practice if bonuses are not fully declared as projected.
  • Reviewing an insurer’s historical bonus track record, not just the current illustration, is one of the better ways to judge how realistic a projection is.

What Is a Non-Guaranteed Bonus?

Participating policies in Singapore — endowments, whole life plans, and some annuities — pool policyholders’ premiums into a “participating fund” that the insurer invests across a mix of bonds, equities, property, and other assets. When that fund performs well, the insurer shares a portion of the profit with policyholders in the form of bonuses. When it doesn’t, bonuses can be reduced or, in poor years, not declared at all.

This is the defining difference from a non-participating policy: par policyholders get a guaranteed base benefit plus the potential for these additional, non-guaranteed bonuses — but nothing above the guaranteed base is ever promised.

MAS requires life insurers to illustrate non-guaranteed benefits at two standardised investment rates of return (currently up to 3.00% p.a. and 4.75% p.a.) precisely so that consumers see a range, rather than a single optimistic number, when comparing par products across insurers.

How Does It Work in Singapore?

Non-guaranteed bonuses generally take two forms:

Bonus Type How It Works
Reversionary bonus Declared periodically, often annually, as a percentage of the sum assured. Once declared and added to the policy, it typically becomes part of the guaranteed value going forward, even though the decision to declare it each year is non-guaranteed.
Terminal bonus A one-off bonus paid only when the policy matures, is surrendered, or a claim is made. It is never guaranteed until the moment of payout, and can be reduced or withheld entirely depending on fund performance.

An insurer’s board typically reviews the participating fund’s performance annually and decides how much surplus, if any, to distribute as bonus versus retain within the fund. This is why two insurers illustrating similar headline returns at policy inception can end up delivering meaningfully different actual payouts over 10, 15, or 20 years, depending on how disciplined and consistent their bonus declarations have been.

A useful due-diligence step before buying a participating policy is asking your adviser or the insurer directly for the fund’s historical bonus declaration rates over the past 5 to 10 years, and comparing those to what was illustrated to policyholders who bought a decade ago. Insurers with a track record of declaring bonuses close to their lower illustrated rate consistently are generally more conservative and predictable than those whose historical declarations have swung more widely between the two illustrated bounds.

Non-Guaranteed Bonus Example

An investor’s whole life policy illustration shows a maturity value of $150,000 at the higher 4.75% illustrated rate, of which only $90,000 is guaranteed and $60,000 is non-guaranteed (comprising reversionary and terminal bonuses). If the insurer’s par fund underperforms over the policy’s lifetime and only declares bonuses consistent with roughly a 3.00% p.a. track, the actual payout might land closer to $115,000 — still above the guaranteed floor, but well short of the higher illustrated figure originally shown at purchase.

Why Non-Guaranteed Bonuses Exist (and Their Upside)

  • Genuine upside potential. In strong market and business conditions, bonuses can meaningfully increase your eventual payout above the guaranteed floor.
  • Smoothing across market cycles. Insurers typically try to smooth bonus declarations to avoid sharp swings, aiming for more stable long-term policyholder outcomes than a direct market-linked product might deliver.
  • Track record is checkable. Unlike a black box, insurers publish historical bonus rates and fund performance, letting you sanity-check how close past illustrations came to reality.
  • You still keep the guaranteed floor. Even if bonuses disappoint entirely, the guaranteed portion of your policy remains contractually protected.

Risks and Limitations

  • Illustrations can create unrealistic expectations. Policyholders sometimes anchor on the higher illustrated rate as if it were promised, when it is explicitly not.
  • Terminal bonuses can be cut or withheld with little notice. These are the least certain component of your projected payout.
  • Insurer-specific performance varies widely. A weaker-performing insurer’s par fund can consistently under-deliver relative to its own historical illustrations.
  • Bonuses are not comparable to guaranteed government instruments. Unlike an SSB or T-bill, there’s genuine variance in what you’ll actually receive.

Guaranteed Benefit vs Non-Guaranteed Bonus

Feature Guaranteed Benefit Non-Guaranteed Bonus
Contractual promise Yes, fixed in the policy contract No, depends on fund performance
Can it be reduced? No Yes, at the insurer’s discretion based on results
Illustrated at One fixed figure Two rates (e.g. 3.00% and 4.75% p.a.) per MAS guidelines
Where it comes from Priced directly into your premium Insurer’s participating fund surplus

The Bottom Line

For Singapore policyholders, treating the non-guaranteed bonus portion of any illustration as a possibility rather than a promise is essential — always anchor your financial planning around the guaranteed figure, and treat any bonus above that as a bonus in the literal sense, not a certainty.

Frequently Asked Questions

What is a non-guaranteed bonus in insurance?

A non-guaranteed bonus is the portion of a participating policy’s projected payout that depends on the insurer’s investment and business performance, rather than being contractually promised at the outset.

What's the difference between a reversionary bonus and a terminal bonus?

A reversionary bonus is declared periodically and, once added to the policy, generally becomes part of the guaranteed value. A terminal bonus is paid only at maturity, surrender, or claim, and is never guaranteed until that point.

At what rates do Singapore insurers illustrate non-guaranteed bonuses?

MAS requires insurers to illustrate non-guaranteed benefits at two standardised rates, currently up to 3.00% p.a. and 4.75% p.a., so consumers can compare policies on a like-for-like basis.

Can a non-guaranteed bonus be reduced after I buy a policy?

Yes, particularly terminal bonuses, which can be adjusted based on how the insurer’s participating fund performs relative to its original assumptions.

Should I rely on the higher illustrated rate when planning my finances?

No. Financial planning should be anchored on the guaranteed benefit, treating any non-guaranteed bonus as a potential upside rather than a certainty.
