What factors affect the cost of key person insurance premiums?

Key person premiums turn on the same drivers as personal cover (age, occupation, health, smoking, cover type, sum insured) plus business-specific factors (revenue, financial evidence, ownership structure). The largest movers are age and sum insured.

Key person cover uses standard panel pricing engines. Each insurer applies the same actuarial models used for individual retail cover, with additional financial-underwriting requirements at higher sums.

The nine main premium drivers

1. Age of the key person

The single largest factor. A 35-year-old key person and a 55-year-old key person on the same cover can differ by 200% or more in annual premium. Older key persons face higher mortality and morbidity probabilities, which flow through to the premium.

2. Sum insured

Direct linear relationship at lower sums. At higher sums (typically above $5M for Life cover), incremental pricing tiers may apply and additional financial underwriting kicks in.

3. Cover type and structure

Life only is the cheapest base. Adding TPD increases the cost by approximately 30 to 50% on a like-for-like sum. Adding Trauma (Critical Illness) adds materially more. Business Expenses cover priced as a monthly benefit follows a separate rating engine.

4. Occupation class

Each panel insurer publishes an occupation guide. Professional and white-collar classes (P1, P2, A) attract the lowest premiums. Heavy-manual classes (M, X) attract the highest. ClearView is explicit that some Class C/CC occupations cannot access Business Expense Cover at all (ClearView ClearChoice PDS (13 May 2024, update 5 June 2025), occupation guide).

5. Smoking status

Non-smokers pay materially less than smokers across all panel insurers. The differential is typically 30 to 50% on a like-for-like quote.

6. Health status and medical history

Full medical underwriting at application. Pre-existing conditions can attract premium loadings, exclusions, or declined cover. The insurer reviews GP reports, specialist reports, and (above defined thresholds) medical examinations.

7. Premium structure (stepped vs level)

Stepped premiums start cheap and rise with age. Level premiums start higher and stay flatter to a stated trigger (often age 65). See AIA Priority Protection PDS (Version 32, 9 November 2025), Section 7; Zurich Wealth Protection PDS (1 November 2025), variable age-stepped section.

8. Waiting and benefit periods (for IP-style cover)

For Business Expenses or IP-style key person cover, a shorter waiting period and longer benefit period both increase the premium.

9. Number of key persons covered

A policy covering 3 key persons costs more than a policy on 1. Multi-life policies may attract small administrative discounts but the underlying risk premium scales linearly with each life insured.

How business factors interact with the price

Beyond the personal-cover drivers, key person cover prices in:

• Industry risk profile: a construction business and a professional-services firm with identical key person ages may price differently if the industry exposure is material.
• Business financials: at higher sums, the insurer reviews the business's financial accounts. Volatile or declining financials may attract additional scrutiny.
• Ownership structure: company-owned, partnership-owned, and trust-owned policies attract identical premium rates. The ownership wrapper does not change the underlying actuarial risk.
• Documentation at application: a clearly evidenced key person valuation can result in a smoother underwriting process and faster issue.

Levers a business can use to reduce premium

1. Right-size the cover: avoid over-insurance. A defensible valuation method (Topic 4 above) prevents premium waste.
2. Choose the cover mix carefully: Life only is cheaper than Life + TPD + Trauma. If the budget is tight, prioritise the cover that addresses the largest financial risk.
3. Use longer waiting periods on Business Expenses cover: a 30-day waiting period costs materially more than a 90-day wait.
4. Match the benefit period to the actual recovery timeline: a to-age-65 benefit period is rarely needed for revenue replacement; 12 to 24 months may suffice.
5. Compare across the panel: identical cover structures can vary 30 to 50% between the cheapest and most expensive insurer for a given key person.
6. Lock cover in early: premiums for a 35-year-old key person are dramatically lower than for a 55-year-old. Securing cover before age and health changes is a structural saving.
7. Maintain healthy lifestyle factors: non-smoker rates apply to confirmed non-smokers; quitting smoking can result in a re-rating after a typical 12-month abstinence period.

What does NOT reduce the premium

• Changing ownership structure (company, partnership, trust) is tax-driven, not price-driven.
• Claiming the cover is for capital purposes vs revenue purposes does not change the underlying premium (it changes the tax treatment).
• Volume discounts are not standard across the panel for key person cover.

This is general advice only. Actual premium quotes depend on the specific key person's age, health, occupation, smoking status, sum insured, and cover mix. Comparing 3 to 5 panel insurers on the same structure is the practical approach to finding value. Discuss with a licensed insurance adviser before locking in cover.
