Deductible (Absolute Deductible)

An insurance deductible (or excess), particularly an absolute deductible, refers to a predetermined amount or proportion of loss specified in a motor vehicle insurance policy that must be borne by the insured. For losses below this threshold, the insurer will not pay compensation; only when the loss exceeds this limit will the insurer cover the excess portion in accordance with policy terms. In motor insurance actuarial practice and risk management, this mechanism is widely employed to mitigate moral hazard and reduce administrative costs associated with processing minor claims.

Operating Mechanism and Calculation Methods of Absolute Deductibles

An absolute deductible applies clear deduction rules during insurance claim settlements, primarily functioning through the following methods:

Absolute Deductible (Fixed Amount):

The policy explicitly stipulates a fixed sum (for example, an absolute deductible of RM500 or RM2,000 per accident). If an accident results in vehicle damage amounting to RM4,000 under a RM500 absolute deductible, the insurer's actual payout will be RM3,500 (RM4,000 - RM500). If the loss is only RM300—falling below the deductible threshold—the entire cost must be borne by the insured, and the insurer will make no payment. 

Absolute Deductible Rate (Proportional Deductible): 

Certain coverages or specific clauses (such as riders/endorsements, designated driving zones, or breaches of specific agreements) apply a percentage-based deductible. For instance, if an absolute deductible rate of 15% is stipulated and the total damage is RM10,000, the insurer will only be liable to pay RM8,500 after deducting the 15% portion (RM1,500).

Core Purpose and Economic Functions of Absolute Deductibles

Introducing an absolute deductible mechanism into the motor insurance market balances the economic interests of both insurance providers and policyholders: 

Curbing Moral Hazard and Adverse Selection:

If motor insurance operated entirely on a "zero deductible" basis, vehicle owners would frequently submit claims even for minor scratches and small dents. An absolute deductible compels motorists to absorb these minor daily repair costs themselves, effectively curbing moral hazard and preventing unnecessary claim applications. 

Lowering Operating Costs for Insurance Companies: 

The labour, surveying, loss assessment, and administrative expenses incurred in processing a minor claim can sometimes approach or even exceed the claim payout itself. By filtering out minor losses, insurers can substantially lower their operating and management overheads, translating these cost savings into more competitive premium rates. 

Differentiated Premium Adjustments: 

Policyholders generally have options when taking up motor coverage. Opting for a policy with a higher absolute deductible will yield a corresponding discount on commercial motor insurance premiums, whereas motorists seeking comprehensive coverage with "zero deductible" must pay higher premiums.

Distinction Between Absolute Deductibles and Related Concepts

In motor insurance jurisprudence and market practice, absolute deductibles are commonly distinguished from relative deductibles and statutory exclusions: 

Absolute Deductible vs. Relative Deductible: 

An absolute deductible (as detailed above) is always deducted from the payout regardless of the total loss amount.

A relative deductible, by contrast, provides no compensation if the loss does not reach the threshold; however, once the loss exceeds the deductible amount, the insurer covers the entire loss in full without any deduction. The vast majority of modern motor vehicle insurance policies adopt absolute deductibles.

Absolute Deductible vs. Statutory Deductible: 

An absolute deductible is a negotiable contractual clause agreed upon within a commercial motor insurance policy. In contrast, statutory deductibles or exclusions are legal restrictions prescribed by laws and regulations that fall outside the scope of insurance coverage (such as losses resulting from drink-driving or drug-driving). The two differ fundamentally in both nature and legal effect.
