What affects the price of life insurance in South Africa?
Life insurance is priced on measured risk. Age, smoking status, health, occupation and hobbies set the personal side; the cover amount and how the premium is structured over time set the product side.
Two people with identical cover can pay very different premiums, because the price is not attached to the policy — it is attached to the person, measured at underwriting.
The personal factors
- Age — the single biggest driver; the risk being insured rises every year
- Smoking status — smokers and non-smokers are priced as different risk pools
- Health — current conditions, medical history and family history all feed the assessment
- Occupation — some jobs carry measurably more risk than others
- Avocations — hazardous hobbies like diving or motorsport are priced in when disclosed
Underwriting: where the price is set
Underwriting is the insurer's assessment of the applicant — health questions, sometimes medical tests — before cover starts. Its output is the actual offer: a standard premium, a loaded (increased) premium for higher measured risk, an exclusion carving a specific condition out of the cover, or occasionally a decline.
This is why quoted premiums and final premiums can differ: the quote prices an assumed person, underwriting prices the real one.
Cover amount and escalation
A larger sum assured costs more — that part is simple arithmetic. The subtler lever is escalation: many policies grow the cover amount each year so it keeps pace with inflation, and the premium pattern grows alongside it. A policy can escalate cover, premiums, both or neither, and each combination produces a different cost path over the decades.
Level vs age-rated: the crossover
Age-rated premiums start lower and increase every year as age (and risk) climbs. Level premiums start higher and stay flat, because the insurer averages the lifetime risk into one price.
Plot both over time and the lines cross: age-rated is cheaper in the early years, level becomes cheaper in the later ones. Which pattern costs less in total depends entirely on how long the policy is kept — a mechanic worth seeing clearly, because the cheaper-today option and the cheaper-overall option can be different products.
The disclosure duty
The whole pricing machine runs on what the applicant declares. Insurers price the disclosed person — and at claim stage, they check. Material non-disclosure — the smoking not mentioned, the condition left off the form — can lead to a claim being reduced or declined and the policy voided, sometimes years after the premiums started.
The mechanic is symmetrical: accurate disclosure is what makes the policy enforceable when it matters. How much cover the premium is buying is its own question — this library covers it in "How much life cover does a person need?"
