Category: Cost
IP premium varies by age, gender, occupation class, smoking status, waiting period, benefit period, monthly benefit, and optional features. A 35-year-old white-collar non-smoker insuring $5,000 per month with a 90-day wait to age 65 will pay materially less than a 50-year-old manual worker with a 30-day wait. Quotes are the only way to size the actual cost.
IMFL's quote engine pulls live rates from each panel insurer using your specific occupation, age, and structure. Below is the framework of what drives the number.
The single largest factor. Premiums rise steeply through your 40s and 50s as disability claim probability rises. A 30-year-old quote and a 50-year-old quote for the same cover can differ by 200% or more.
Women typically pay more for IP than men at younger ages, reflecting historical claims experience. The differential narrows with age.
Each panel insurer publishes an occupation guide. Class codes range from professional (P1, P2) at the lowest premium to heavy-manual (M, X) at the highest. The class drives both premium and which benefit periods are available. ClearView explicitly restricts CC2 and CC5 classes to 2- or 5-year benefit periods. See ClearView ClearChoice PDS (13 May 2024, update 5 June 2025), occupation guide.
Non-smokers pay materially less than smokers across all panel insurers. The differential is significant: often 30-50% on a like-for-like quote.
Shorter waiting periods cost more. A 30-day wait costs materially more than a 90-day wait. A 2-year wait is the cheapest option on the panel. See AIA Priority Protection PDS (Version 32, 9 November 2025) and Zurich Wealth Protection PDS (1 November 2025) on waiting-period options.
Longer benefit periods cost more. A 2-year benefit period is materially cheaper than a to-age-65 benefit period for the same monthly amount. The cost difference reflects the insurer's expected lifetime claim exposure.
Increasing Claim Option (in-claim CPI escalation), Super Contribution Option (employer SG paid while on claim), Day 1 Accident Benefit, Specified Injury Benefit. Each option adds a percentage to the base premium. See AIA Priority Protection PDS Section 7 (Built-in and Optional Benefits); TAL Accelerated Protection PDS (12 December 2024) Section 2.6.3.
The default on most panel contracts. Premium recalculates at each policy anniversary based on your current age. Starts cheap. Rises steeply in later years.
Flat for a defined period or until a stated age (often 65). Starts higher than stepped. Cheaper in aggregate if you hold the policy for many years.
A stepped structure that also tracks insurer-driven rate changes. See Zurich Wealth Protection PDS (variable age-stepped premium structure).
The choice between stepped and level is a separate decision worth modelling against your expected holding period. A long-term policyholder may save with level premiums even though the up-front cost is higher.
Each panel PDS sets out premium calculation rules:
For an identical cover structure, panel premiums can vary by 30-50% between the cheapest and most expensive insurer. The cheapest is not always the right pick because definitions, mental-illness handling, and occupation-class treatment differ (see the FAQ on comparing IP policies). Comparing 3-5 insurers across IMFL's panel for your specific structure is the practical approach.
Any premium range cited here is illustrative. Your actual quote depends on your specific age, gender, occupation class, smoking status, health history, structure choices, and the insurer underwriting your cover. Use a licensed adviser to walk through the panel quotes side-by-side under general advice.
