How Insurance Deductibles Work

The basic idea

A deductible is the portion of a covered loss you are responsible for before the insurer's payment is calculated under the policy.

For example, if a covered property loss is $5,000 and the applicable deductible is $1,000, the policy may pay based on the remaining covered amount, subject to limits, valuation terms, exclusions, and other policy provisions.

Deductibles can differ by coverage

One policy can contain more than one deductible. Auto collision and comprehensive coverage may have separate deductibles. Home policies can also use different deductibles for certain causes of loss, and some property policies use percentage-based deductibles.

Do not assume the deductible shown most prominently applies to every claim.

Higher deductible, lower premium—usually with more risk

Choosing a higher deductible can reduce premium in some cases because you agree to absorb more of a covered loss yourself.

The tradeoff is liquidity. A deductible that looks attractive at renewal may be difficult to pay after a sudden loss.

When comparing quotes, ask whether you could comfortably cover the deductible from savings without relying on high-cost debt.

Deductibles do not replace coverage limits

A deductible and a coverage limit answer different questions. The deductible is your share of a covered loss; the limit is the maximum amount the policy will pay for the applicable coverage, subject to policy terms.

A low deductible does not compensate for inadequate limits, and a high limit does not eliminate the deductible.

Compare quotes apples to apples

Two quotes can appear very different in price because the deductible structures are not the same.

Compare:

• deductible amount,
• whether it is fixed-dollar or percentage-based,
• which coverages it applies to,
• policy limits,
• exclusions,
• valuation method, and
• endorsements or optional protections.

See Insurance Comparison Guide for a broader checklist.
