How Much Does Professional Liability Insurance Cost?
Professional liability insurance — also known as Errors & Omissions (E&O) insurance — costs between $500 and $5,000 per year for most professionals and small firms. The average cost for a $1 million policy is roughly $1,000 to $3,000 annually, though some high-risk professions pay significantly more.
Professional liability protects you when a client claims your advice, services, or work product caused them financial harm. It covers legal defense costs and settlements, which can easily reach six figures even for unfounded claims. Understanding the cost factors helps you budget and find the best value.
Professional Liability Cost by Profession
Your profession is the biggest factor in E&O pricing. Professions where bad advice can cause significant financial harm pay more.

|---|---|---|---|
| IT Consultant | $1,000 – $3,000 | Medium-High | System failures, data loss, project delays |
| Management Consultant | $800 – $2,500 | Medium | Bad strategic advice, missed deadlines |
| Accountant / CPA | $1,000 – $3,500 | Medium-High | Tax errors, audit failures, misstatements |

| Healthcare (malpractice) | $3,000 – $30,000+ | Very High | Patient injury, misdiagnosis |
Professional Liability Cost by Revenue
As your revenue grows, so does your E&O exposure — higher revenue typically means larger client engagements and bigger potential claims.
| Annual Revenue | Average E&O Cost (Annual) | Typical Limits |
|---|---|---|
| Under $50K | $400 – $800 | $250K – $500K |
| $50K – $100K | $500 – $1,200 | $500K – $1M |
| $100K – $250K | $800 – $2,000 | $1M |
| $250K – $500K | $1,200 – $3,000 | $1M |
| $500K – $1M | $2,000 – $5,000 | $1M – $2M |
| $1M – $5M | $3,500 – $10,000 | $2M – $5M |
| $5M+ | $8,000 – $25,000+ | $5M+ |
What Affects Your Professional Liability Premium?
Carriers evaluate multiple factors when pricing E&O coverage:
- Profession / industry — The type of advice or service you provide determines your base risk profile
- Revenue — Higher revenue means larger engagements and more exposure
- Years in business — Newer businesses may pay more due to lack of track record
- Claims history — Prior E&O claims significantly increase premiums
- Coverage limits — $2M costs roughly 40–60% more than $1M
- Deductible — Higher deductibles ($2,500–$10,000) reduce premiums
- Contract values — Working on large contracts increases your risk exposure
- Client type — Serving enterprise or government clients often requires higher limits
Claims-Made vs. Occurrence Policies
Professional liability policies are almost always written on a "claims-made" basis, which is important to understand for cost planning:
| Policy Type | How It Works | Cost Implications |
|---|---|---|
| Claims-Made | Covers claims made during the policy period | Premiums start lower, increase annually for 5–7 years until reaching "mature" rate |
| Occurrence | Covers incidents that occurred during the policy period | Higher initial premiums, no tail coverage needed |
With claims-made policies, you may need "tail coverage" (an extended reporting period) when you cancel or switch carriers. Tail coverage typically costs 150–200% of your final annual premium as a one-time charge.
How to Reduce Professional Liability Costs
- Maintain detailed contracts — Clear scope-of-work agreements and limitation of liability clauses reduce your risk profile
- Document everything — Thorough records of advice given, decisions made, and client approvals protect against claims
- Get client sign-offs — Written approvals at key milestones create a paper trail
- Choose higher deductibles — Increasing your deductible from $1,000 to $5,000 can save 10–15%
- Compare carriers — E&O pricing varies significantly; specialty carriers often offer better rates for specific professions
- Bundle policies — Packaging E&O with GL or a BOP may qualify for multi-policy discounts
Why Compare E&O Quotes?
Professional liability is a specialty market where pricing varies dramatically between carriers. A carrier that specializes in IT consulting E&O might offer rates 30–50% lower than a generalist carrier for the same coverage. Conversely, that same carrier might be expensive for accounting E&O.
