What determines a term life premium: age, sex, smoking, health, term, sum assured and riders

A term life premium is the price an insurer puts on your position in its risk pool: the higher the risk, the more cover and the longer it runs, the higher the premium usually is. The LIA Guide to Medical Underwriting (April 2024, v3.0) puts it this way: the premiums paid by all policyholders go into a common pool of funds, and premiums must be commensurate with risk for the pool to keep paying claims over the long run. This article divides the drivers of the premium into two groups, personal risk factors and product structure factors, and explains which premiums are guaranteed to stay level and which are recalculated on renewal or conversion. This site does not publish any insurer's premium figures; obtain actual numbers through compareFIRST or an insurer's quotation.

The logic underneath: the risk pool and the principle of commensurate premiums

Insurance is risk sharing: many people pay premiums into the same pool of funds, and the few who suffer an insured event are paid from it. The LIA guide notes that insurers adjust premiums or cover according to each person's risk profile so that it remains fair relative to the others in the pool. In general, the older a person is, the more likely they are to fall ill, become disabled or face a higher risk of premature death; younger people usually have a longer life expectancy and a lower likelihood of critical illness, and so usually pay lower premiums. An applicant with a medical history may have a loading applied to the application, or may even be declined.

LIA's 2018 protection guide, in its advice to young people, says to insure early: start while healthy and premiums are low, because premiums rise with age (Apr 2018). Beyond the cost of risk, premiums also have to cover the insurer's operating and other costs; each insurer's assumptions and expense structure differ, which is why quotations differ for the same profile.

Personal risk factors: what the insurer looks at

The LIA guide lists the factors an insurer considers when assessing a risk profile. The table below is built on that list, with smoking status added as the standard filter on comparison platforms.

Smoking status deserves a separate note. compareFIRST includes "smoking status" among its filters, and the LIA guide's case examples distinguish a "non-smoker" from a "social smoker". But how "non-smoker" is defined (whether e-cigarettes or nicotine replacement products count, and how long after quitting someone is rated as a non-smoker) is set by each insurer in its application questionnaire, and the questions must be answered truthfully. How underwriting handles loadings, exclusions, postponement and declines is covered in Underwriting for term life.

Product structure factors: sum assured, term, payment mode and riders

Besides personal risk, the structure of the product itself drives the premium: the larger the sum assured and the longer the policy term and premium term, the more risk the insurer carries and the higher the premium usually is. In its comparison of term and bundled products, MoneySense also notes that a term policy with a higher sum assured and longer cover and premium terms may cost more than a bundled product (updated 28 Sep 2026).

Does a longer term always mean a higher total premium?

The annual premium usually rises as the term lengthens, so the total paid naturally rises too. The more meaningful comparison is therefore not "which is cheaper" but "to cover the same period of liability, which structure keeps total cost and uncertainty more under control". The table below uses three paths to show the difference.

It is often said that locking in a long term while young usually costs less overall. The comparison is with buying again at an older age, and it assumes that the applicant will still pass underwriting then. The actual total cost also depends on how many years of cover you really need and on future rates and health, so it should be taken from insurers' quotations rather than concluded directly from rules of thumb.

Which premiums are guaranteed and which are recalculated

"Guaranteed renewal" and "guaranteed premium" are two different things. MoneySense's position is that the premium stays constant throughout the period except when the policy is renewed, converted or reinstated; the premium on renewal is often not guaranteed and is revised according to age after renewal.

Where to compare publicly

compareFIRST is a joint effort by the Consumers Association of Singapore (CASE), the Monetary Authority of Singapore (MAS), the Life Insurance Association Singapore (LIA) and MoneySENSE; it is a purely informational portal that does not sell insurance itself (LIA consumer guide, May 2020). It can filter by date of birth, sex, smoking status, premium type, policy term and premium term, premium amount, sum assured and whether critical illness cover is included, and spans Direct Purchase Insurance, term, whole life, endowment and investment-linked categories (accessed 22 Oct 2026).

When comparing, hold five conditions fixed: date of birth, sex, smoking status, sum assured and policy term, then check riders and options separately. The comparison result is only a starting point; the actual premium depends on the insurer's underwriting outcome and formal quotation.
