Key Takeaways

  • A deductible is the amount the insured pays out-of-pocket before insurance pays — higher deductibles mean lower premiums
  • Flat deductibles are a specific dollar amount ($500, $1,000); percentage deductibles are a % of coverage (10%, 20%)
  • Policy limits can be per-occurrence (each event), aggregate (total for policy period), or split limits (separate limits for different coverages)
  • Sublimits cap coverage for specific types of property (cash, jewelry, firearms) at amounts lower than the overall limit
  • The relationship: higher deductibles = lower premiums; higher limits = higher premiums

Deductibles and Policy Limits

Deductibles and limits define how much the insured pays versus how much the insurer pays. Understanding these concepts is essential for proper coverage.

What Is a Deductible?

Definition: The amount the insured must pay out-of-pocket before insurance coverage kicks in.

Purpose of Deductibles:

  • Eliminate small nuisance claims
  • Reduce premium costs
  • Encourage loss prevention (insured has "skin in the game")
  • Share risk between insured and insurer

Types of Deductibles

1. Flat Deductible (Per-Occurrence)

Definition: A specific dollar amount that applies to each loss.

Examples: $500, $1,000, $2,500

How It Works:

  • Loss: $5,000
  • Deductible: $1,000
  • Insurance pays: $4,000

Common For: Homeowners, auto, general property policies

2. Percentage Deductible

Definition: A percentage of the covered property value or coverage amount.

Examples: 2%, 5%, 10%, 20%

How It Works:

  • Dwelling coverage: $400,000
  • Earthquake deductible: 15%
  • Deductible amount: $60,000
  • If $100,000 earthquake loss: Insured pays $60,000, insurer pays $40,000

Common For: Earthquake, hurricane/wind, flood coverage

3. Aggregate Deductible

Definition: A total deductible amount for all losses during the policy period.

How It Works:

  • Annual aggregate deductible: $5,000
  • First loss ($2,000): Insured pays $2,000 (remaining aggregate: $3,000)
  • Second loss ($4,000): Insured pays $3,000, insurer pays $1,000
  • Third loss ($3,000): Insurer pays full $3,000 (aggregate satisfied)

Common For: Commercial policies, umbrella policies

4. Split Deductible

Definition: Different deductible amounts for different perils.

Example:

  • All perils: $1,000 flat deductible
  • Wind/Hail: 2% of Coverage A
  • Earthquake: 15% of Coverage A

Deductible vs. Premium Trade-off

Deductible LevelPremium ImpactBest For
Low ($250-$500)Higher premiumsThose wanting maximum protection
Medium ($1,000)Moderate premiumsAverage homeowners
High ($2,500+)Lower premiumsThose who can self-insure small losses

Rule of Thumb: Increasing your deductible from $500 to $1,000 can reduce premiums by 10-20%.


Policy Limits

Definition: The maximum amount an insurer will pay for a covered loss.

Types of Limits

1. Per-Occurrence Limit

Maximum payment for any single event/loss.

Example: $300,000 per-occurrence limit

  • One fire causes $400,000 damage
  • Insurer pays maximum $300,000

2. Aggregate Limit

Maximum total payment for all losses during the policy period.

Example: $1,000,000 annual aggregate

  • Multiple claims throughout the year
  • Total payments cannot exceed $1,000,000

3. Split Limits

Separate limits for different coverages or categories.

Auto Example: 100/300/100

  • $100,000 per person bodily injury
  • $300,000 per accident bodily injury
  • $100,000 property damage

4. Combined Single Limit (CSL)

One limit covering all damages in an occurrence.

Example: $500,000 CSL

  • Covers bodily injury AND property damage
  • More flexible than split limits

Sublimits

Definition: Maximum amounts for specific categories of property that are LOWER than the overall policy limit.

Common Homeowners Sublimits

Property TypeTypical Sublimit
Cash/Currency$200
Securities/Documents$1,500
Jewelry/Watches$1,500
Firearms$2,500
Silverware$2,500
Business Property$2,500
Electronics$5,000

Example:

  • Personal property limit: $150,000
  • Jewelry sublimit: $1,500
  • $10,000 ring is stolen
  • Maximum payment: $1,500 (sublimit applies)

How to Increase Sublimits

  • Scheduled Personal Property Endorsement — List specific items with agreed values
  • Floater policy — Separate policy for valuables
  • Increased sublimit endorsement — Raise category limits

Limits and Deductibles Working Together

Example Calculation:

Given:

  • Policy limit: $250,000
  • Deductible: $2,500
  • Loss: $100,000

Payment: $100,000 (loss) - $2,500 (deductible) = $97,500 paid by insurer

If Loss Was $300,000: $250,000 (limit, less than loss) - $2,500 (deductible) = $247,500 paid


Other Insurance Clauses

When multiple policies cover the same loss:

Pro Rata (Contribution by Limits)

Each insurer pays proportionally based on their limit.

Formula: (Policy Limit ÷ Total of All Limits) × Loss

Primary and Excess

One policy pays first (primary), other pays only if primary is exhausted (excess).

Example:

  • Homeowners is primary: Pays first $300,000
  • Umbrella is excess: Pays amounts above $300,000
