The narrow, legal meaning
"Guaranteed" refers specifically to the contractually specified minimum figures in your policy -- typically a guaranteed cash value at each policy year and a guaranteed maturity value. These are the numbers the insurer is legally obligated to pay, full stop, regardless of how markets or the insurer's fund perform.
What it does NOT cover
Any bonus -- reversionary or terminal -- is by definition non-guaranteed, even after it's been declared once. Illustrated totals that combine guaranteed and projected bonus figures are not themselves guaranteed, even though they sit on the same page and often in a similarly formatted column. Marketing headlines like "guaranteed to grow" typically refer to the guaranteed component only continuing to accrue, not the total illustrated figure being locked in.
Why the distinction actually matters
See Capital Guaranteed Plans and Guaranteed + Bonus Plans for how large the gap between these two categories tends to be in practice -- often several percentage points of annualised return, which compounds into a meaningful dollar difference over a 10 to 25-year term.
A simple test before you buy
Ask directly: "If every non-guaranteed bonus were paid at zero from today, what would I receive at maturity?" That answer is the true floor of the product. Compare that floor -- not the illustrated total -- against CPF, SSB, or T-bill rates before deciding whether the plan's non-guaranteed upside is worth the trade.
Once a bonus is declared, is it guaranteed after that?
Reversionary bonuses, once declared, are typically locked in for policies that stay in force -- but terminal bonuses generally remain non-guaranteed until maturity or full surrender, and future reversionary bonus rates can still be revised for new declarations.
Do all insurers use the word 'guaranteed' the same way?
The regulatory definition is standardised across Singapore insurers for benefit illustration purposes, but marketing language around it varies -- always check the specific guaranteed cash value column in your own illustration rather than relying on cover-page language.
