Per-occurrence vs aggregate limit is one of the most misunderstood parts of a business insurance policy. Most owners see “$1 million in coverage” on their declaration page and assume they are fully protected. However, that number could mean very different things depending on whether it is your per-occurrence limit or your aggregate limit. Getting this wrong can leave you paying a massive claim out of pocket. In most cases, you need to understand both numbers before you sign anything.
Per-Occurrence Vs Aggregate Limit: The Key Differences
The per-occurrence vs aggregate limit distinction controls how your insurer pays claims. Think of the per-occurrence limit as a cap on any single event. A customer slips in your store and sues for $800,000. If your per-occurrence limit is $1 million, the policy covers it in full. A second slip-and-fall later that year also gets up to $1 million. Each incident is treated separately.
Your aggregate limit, however, is the total budget for the entire policy period. As a result, every claim payment chips away at it. Once that total is gone, your insurer stops paying — even if you have months left on your policy. Here is how the two limits compare side by side.
| Factor | Per-Occurrence Limit | Aggregate Limit |
|---|---|---|
| What it caps | One single claim or incident | All claims combined for the policy year |
| Resets after each claim? | Yes — each new incident gets the full limit | No — it is a running total that only resets at renewal |
| Typical amount | $1 million (standard) or $2 million | $2 million (usually 2× the per-occurrence limit) |
| What happens when exhausted | You pay the excess on that one claim | You are effectively uninsured for the rest of the year |
| What owners overlook | Defense costs may count against this limit | Multiple small claims can quietly drain it before a big one hits |
| Who should pay attention | Owners facing large single-event risk (fire, injury lawsuits) | Owners in high-claim-frequency trades (restaurants, contractors) |
Most general liability policies also include a separate products-completed operations aggregate. This is a second bucket that only covers claims arising from your finished work or products you sold. For example, a plumber’s faulty installation that causes water damage six months later draws from this aggregate — not from the general one. Understanding the per-occurrence vs aggregate limit structure means knowing you actually have three caps, not two.
When Each Limit Is the Better Focus
Your per-occurrence limit matters most when your biggest risk is a single catastrophic event. For example, a general contractor working on a commercial build faces the possibility of one serious injury lawsuit that could exceed $1 million. In that situation, the per-occurrence vs aggregate limit question tilts toward maximizing the per-occurrence number. Many commercial contracts now require $2 million per-occurrence before you can bid on a job.
Your aggregate limit matters more when you face frequent smaller claims. A busy restaurant with 200 daily customers might see several slip-and-fall claims in one year. Each one might cost $100,000 to $300,000 to settle. Individually, none of them threatens the per-occurrence limit. However, four or five of them together can exhaust a $2 million aggregate. Retail stores, food trucks, and child-care centers face the same pattern. In most cases, these businesses should prioritize a higher aggregate.
Typically, the smartest move is to look at your claim history and your industry’s loss data. If you have never had a claim but your trade carries catastrophic risk, focus on the per-occurrence number. If you see steady small claims year after year, the aggregate is where you are exposed. The per-occurrence vs aggregate limit balance should match your actual risk profile.
The Costs and Trade-Offs
A standard $1M per-occurrence / $2M aggregate general liability policy costs most small businesses about $1,474 per year, or roughly $123 per month. However, that average hides huge variation by trade. A solo consultant might pay $50 per month. A plumbing contractor with a crew could pay $180 per month or more.
| Business Type | Typical Limits | Annual Premium | Monthly Cost |
|---|---|---|---|
| Consultant (desk-based) | $1M / $2M | $600 | $50 |
| Retail store | $1M / $2M | $500 | $42 |
| Restaurant | $1M / $2M | $876–$1,692 | $73–$141 |
| Electrician (solo) | $1M / $2M | $500–$800 | $42–$67 |
| General contractor | $1M / $2M | $750–$2,500 | $63–$208 |
Doubling your limits from $1M/$2M to $2M/$4M does not double your premium. The increase is typically modest — often 15% to 30% more — because the insurer is only covering a less likely layer of loss. As a result, when a client contract demands higher limits, it is usually affordable to comply. The per-occurrence vs aggregate limit jump from standard to doubled coverage might add $20 to $50 per month for most trades.
The real trade-off is between premium savings and gap risk. A $500K per-occurrence / $1M aggregate policy saves money upfront. However, one serious lawsuit can blow through both limits and leave you personally liable. For most owners, the standard $1M/$2M is the floor, not the ceiling. If your contracts or your claim frequency suggest higher exposure, an umbrella policy — typically $200 to $400 per year for $1 million in additional coverage — is far cheaper than paying a gap out of pocket.
How the Per-Occurrence vs Aggregate Limit Varies by Trade and State
The per-occurrence vs aggregate limit you need depends heavily on your trade and your state. Construction trades face the tightest requirements because the stakes are highest. Many states set minimum liability insurance limits for contractor licensing, but those minimums are often far below what clients actually require.

| Washington | $250,000 combined single limit | $1M / $2M | $1,400/year |

| Texas | No state GL mandate for most trades | $1M / $2M | $1,000–$2,500/year |
High-litigation states like California and New York carry the highest premiums. Typically, the per-occurrence vs aggregate limit structure stays the same nationwide — $1M/$2M is standard everywhere. However, what you pay for those limits can vary by 50% or more depending on your ZIP code. Always confirm exact requirements with a licensed insurance agent and your state’s contractor licensing board before purchasing a policy.
Frequently Asked Questions
What happens if my aggregate limit runs out mid-year?
Your insurer stops paying claims for the rest of the policy period. You are responsible for any additional covered losses out of pocket. In most cases, you can purchase an umbrella or excess liability policy that “drops down” to act as your primary coverage once the underlying aggregate is exhausted. This is one reason understanding the per-occurrence vs aggregate limit matters — a drained aggregate leaves you exposed even with months left on your policy.
Can I raise just my per-occurrence limit without changing the aggregate?
Typically, no. Most insurers tie the two together at a standard ratio — usually 1:2. A $1M per-occurrence policy comes with a $2M aggregate. However, some carriers offer custom structures, especially for higher-risk trades. An excess liability policy can also boost your per-occurrence limit independently. Ask your agent about the per-occurrence vs aggregate limit options available for your specific trade.
Do defense costs count against my limits?
On a standard commercial general liability policy, defense costs are typically paid in addition to the policy limits. This means hiring a lawyer to fight a lawsuit does not reduce your per-occurrence or aggregate limits. However, some professional liability and specialty policies include defense costs within the limit. Always check your policy’s “duty to defend” language. The per-occurrence vs aggregate limit on your declarations page may or may not include legal defense — and the difference can be hundreds of thousands of dollars.
