Deductible

Also known as: Excess (UK/AU) Self-insured retention

A deductible is the fixed dollar amount (or percentage of the claim or insured value) that a policyholder must pay out of pocket before the insurer pays the remainder of a covered claim, up to the policy limit.

How a deductible works

Suppose your home insurance has a $1,000 deductible and a covered storm causes $6,000 of damage. You pay the first $1,000; your insurer pays the remaining $5,000. If the damage had been $800 — less than your deductible — you would pay the full $800 and the insurer would pay nothing.

This is why it is generally not worth claiming for small losses that are close to or below your deductible: you absorb the cost either way, and making a claim may affect your no-claims bonus or future premiums. Our guide to deductibles and out-of-pocket maximums walks through a detailed worked example with a claims-cost table.

Types of deductible

Fixed dollar

The most common type. A fixed amount — e.g. $500 or $1,000 — applies to each claim regardless of the total loss size. Used in auto, home contents, and most commercial policies.

Percentage-based

Calculated as a percentage of the insured value or claim amount — e.g. 2% of the home's insured value. Common for windstorm, hurricane, and earthquake coverage in high-risk regions.

Annual (aggregate)

Applies once per policy year. After you have paid the deductible total across multiple claims in a year, the insurer covers 100% of subsequent claims. Typical in health insurance.

Per-occurrence

Resets with each separate claim event. Most auto and property policies use per-occurrence deductibles, meaning you pay the deductible again each time you file a new claim.

The deductible–premium trade-off

A higher deductible lowers your premium because you are agreeing to absorb more of the cost of frequent, small losses yourself. Insurers price risk on expected claim costs, so transferring the small-loss risk back to you reduces their expected payout.

The right deductible level depends on your financial position: if you cannot comfortably afford to pay a $2,000 deductible from savings, choosing one to save $200 per year on premium is a poor trade. The Insurance Information Institute recommends keeping an emergency fund equal to at least your deductible. The NAIC consumer guide has state-by-state average premium data to benchmark your own costs.
