Policy Limits — Insurance Definition (2026)
Policy limits define the maximum dollar amount an insurance carrier will pay for a covered loss. Limits are not a single number — they operate as a layered system of per-person, per-occurrence, and aggregate caps, plus sublimits for specific categories of coverage. Understanding which limit applies to a given loss is as important as knowing the limit amounts.
Auto Liability: Reading the 100/300/100 Shorthand
The most common limit notation in personal auto insurance encodes three distinct caps:
100 / 300 / 100
First number (100): Bodily injury liability per person ($100,000 maximum per injured person)
Second number (300): Bodily injury liability per occurrence ($300,000 maximum total per accident)
Third number (100): Property damage liability per occurrence ($100,000 maximum)In an accident where the policyholder is at fault and injures three people, each injured party can collect up to $100,000 individually, but the total payout for all bodily injury claims from that single accident cannot exceed $300,000. Property damage to the other vehicle and any other property damaged in the same accident is capped at $100,000.
State minimum limits vary considerably. California requires 15/30/5 — limits that were set in the 1960s and provide essentially no meaningful protection in a modern multi-vehicle accident. Most insurance professionals recommend 100/300/100 as a practical floor for drivers with significant assets; umbrella coverage extends beyond this for further protection. See our umbrella policy entry.
Homeowners Limits: Coverage Letters A Through F
Standard HO forms structure limits across six coverage components:
| Coverage | Description | Typical Limit |
|---|---|---|
| Coverage A (Dwelling) | Main structure | Replacement cost |
| Coverage B (Other Structures) | Fences, detached garage | 10% of Coverage A |
| Coverage C (Personal Property) | Contents | 50–70% of Coverage A |
| Coverage D (Loss of Use) | Additional living expenses | 20–30% of Coverage A |
| Coverage E (Personal Liability) | Third-party bodily injury / property damage | $100,000–$500,000 |
| Coverage F (Medical Payments) | Minor injuries to guests | $1,000–$5,000 |
Coverage B, C, and D limits are typically expressed as percentages of Coverage A, automatically scaling with the dwelling limit. This is important: if Coverage A is underinsured relative to actual replacement cost, all percentage-based sub-limits are also underinsured proportionally.
Sublimits: The Gaps Within the Policy
Most homeowners policies impose sublimits for specific categories of personal property that are lower than the overall Coverage C limit:
- Jewelry and watches: Typically $1,500–$2,500 per item / $5,000–$10,000 aggregate
- Silverware and goldware: Often $2,500
- Firearms: Often $2,500
- Business property at home: Often $2,500
- Electronic data: Often $1,500 or excluded
High-value items above these sublimits require a scheduled personal property endorsement (a floater) with stated-value or agreed-value coverage. Sublimits are among the most commonly encountered coverage gaps at the time of a theft or fire claim.
Per-Occurrence vs. Aggregate Limits
Per-occurrence limits cap the carrier’s liability from any single event. Aggregate limits cap total payments over the policy period (typically one year). Most personal lines policies use per-occurrence limits. Commercial general liability (CGL) policies commonly include both: a per-occurrence limit and an annual aggregate, meaning a series of separate incidents can collectively exhaust the annual aggregate even if no single incident reaches the per-occurrence cap.
2026 Context: Minimum Limits Adequacy
Auto liability minimum limits set by state statutes have not kept pace with medical costs or average vehicle values. An at-fault driver with only state-minimum limits in most states faces personal asset exposure — anything above their policy limit can be pursued as a judgment against personal property, wages, and savings. The practical advice from any plaintiff’s attorney: carry 100/300/100 or higher, and consider an umbrella.
Why It Matters
Limits interact with exclusions: A policy limit of $500,000 for personal liability coverage (Coverage E) is irrelevant if the claim falls under an exclusion. Limits cap covered losses; exclusions define what is covered.
The umbrella layer: An umbrella policy provides liability coverage in excess of the underlying auto and homeowners limits, typically starting at $1M increments. The umbrella kicks in only after the underlying limits are exhausted — making the underlying limits both a floor for out-of-pocket exposure and a prerequisite for umbrella activation.
