Professional Liability Insurance (Errors & Omissions, or E&O) protects service providers against claims of negligence, mistakes, or failure to perform professional services. For U.S.-based firms, E&O premiums vary widely by profession, revenue, claims history, and location. This guide gives practical, commercial-focused pricing benchmarks, vendor price signals, and actionable steps to get transparent quotes in major U.S. markets like New York, Los Angeles, Chicago, Houston, and Miami.
Quick takeaways
- Typical annual premiums for a $1,000,000 per claim / $1,000,000 aggregate policy (the common “1M/1M”) range from $300 to $12,000+ depending on profession and firm size.
- Small solo consultants and real estate agents often pay $300–$2,000/year. Tech/software firms, architects/engineers, and large accounting firms pay more.
- Geography matters: New York City and San Francisco typically face higher rates than smaller metro areas.
- Compare both reputation and policy terms — cheaper premiums may have narrower coverage or higher deductibles.

National pricing benchmarks by profession (USA-focused)
Below are representative annual premium ranges for a standard $1M/$1M policy and a typical deductible (commercial U.S. market). These are estimates based on industry marketplaces and insurer guidance; actual quotes will vary.
| Profession | Typical annual premium (1M/1M) | Typical deductible | Notes (claims & risk drivers) |
|---|---|---|---|
| Independent consultant / coach (sole proprietor) | $300 – $1,500 | $500 – $2,500 | Low-risk services—premium depends on client type and contract terms |
| IT consultant / software developer | $800 – $3,000 | $1,000 – $5,000 | Higher due to potential for data/system failures and downstream losses |
| Marketing / advertising agency | $600 – $3,500 | $1,000 – $5,000 | Reputation and IP risks; social media ad errors increase exposure |
| Accountant / CPA firm (small) | $1,200 – $6,000 | $1,000 – $5,000 | Financial advice and tax filings raise exposure |
| Architect / Engineer (small firm) | $3,000 – $12,000+ | $2,500 – $10,000 | High exposure from construction defects and project values |
| Real estate agents / brokers | $300 – $2,000 | $500 – $2,500 | Varies by transaction volume and state licensing rules |
| Insurance agents / brokers | $800 – $4,000 | $1,000 – $5,000 | Errors in policy placement cause claims |
| Legal professionals (attorney malpractice) | Varies widely; typically separate legal malpractice policies | Varies (often higher) | Lawyers typically purchase professional liability from specialized carriers; premiums can be significantly higher than other professions |

How location affects your premium (examples)
- New York City and San Francisco: Higher litigation frequency, larger client contracts, and higher legal defense cost -> +20%–50% on baseline premium.
- Chicago, Los Angeles: Mid-to-high market; industry mix (tech, finance, creatives) creates varied risk.
- Houston, Miami, Phoenix: Typically lower than NYC/SF but industry concentration (energy, international transactions) can raise costs for certain professions.
If you're a small architecture firm in Los Angeles vs. Phoenix, expect higher premiums in LA due to construction litigation trends and higher average project values.
Key cost drivers (brief)
- Revenue / payroll: Higher revenue increases limit need and premium.
- Claims history: Past claims materially increase premiums and surcharges.
- Contractual risk transfer: Contracts requiring additional insureds or indemnities raise underwriting scrutiny.
- Industry/profession: Some professions have intrinsic higher exposure (A/E, accounting).
- Limits & deductibles: Higher limits and lower deductibles raise premiums.
- State regulations & licensing: Some states have higher malpractice or consumer-protection activity.

What firms should ask insurers (buyer’s checklist)
- Is the policy claims-made or occurrence? (E&O is usually claims-made; retroactive date matters.)
- Are subcontractors and vicarious exposures covered?
- Are defense costs inside or outside the limit?
- What endorsements are excluded (e.g., cyber, IP)?
- How does prior act coverage work on policy changes?

Ways to lower premium (legally)
- Increase deductible (if cashflow allows).
- Improve contract language to reduce risk allocation.
- Bundle policies (package general liability + professional liability) with the same carrier for multi-policy discounts.
- Implement risk management programs, documented processes, and client engagement letters.
- Shop multiple carriers and use a marketplace/broker — price differences between carriers on the same application can be substantial.

Final checklist before you buy
- Confirm policy form, exclusions, and retroactive date.
- Get multiple quotes from both specialty carriers (Chubb, CNA) and digital-first insurers (Hiscox) or marketplaces (Insureon).
- Consider higher limits if contractually required by clients.
- Document internal controls and share them with underwriters for potential credits.
By combining marketplace benchmark data, targeted underwriting improvements, and strategic carrier selection, most U.S. firms can find a commercially viable E&O solution that balances price and coverage.
