Estimate professional liability (E&O) insurance premiums based on revenue, profession risk level, and coverage limits.
Professional liability insurance, also known as errors and omissions (E&O) insurance, protects professionals and businesses against claims of negligence, errors, or failure to perform professional duties. This coverage is essential for consultants, accountants, architects, engineers, attorneys, technology companies, and any professional service provider.
Unlike general liability insurance which covers physical injury and property damage, professional liability covers financial losses resulting from professional mistakes or omissions. Premiums vary significantly based on your profession, revenue, claims history, and coverage limits, typically ranging from $500–$3,000 for low-risk professions to $5,000–$20,000+ for higher-risk specialties.

Base Premium = (Revenue ÷ 1,000) × Base Rate Adjusted Premium = Base Premium × Profession Risk Factor × Claims Factor × Limits Multiplier Final Premium = Adjusted Premium × (1 − Deductible Credit)
Result: $1,710 annual premium
With $300,000 in revenue, a $4.00 base rate, and a profession risk factor of 1.5: Base premium = (300,000 / 1,000) × 4.00 = $1,200. Adjusted for profession risk: $1,200 × 1.5 = $1,800. With 5% deductible credit: $1,800 × 0.95 = $1,710.
Different professions carry different risk levels. Financial advisors, architects, and healthcare providers face higher claim frequency and severity than general consultants or IT firms. Your profession's historical claims data directly impacts your premium.
Most professional liability policies are written on a claims-made basis. This means the policy in force when the claim is made responds, not the policy in force when the error occurred. Retroactive dates and prior acts coverage are important policy features to review.
Implementing quality control procedures, using standardized engagement letters, maintaining thorough documentation, carrying appropriate staffing levels, and conducting regular peer reviews can improve your risk profile and potentially reduce premiums.
Select limits based on your contract requirements, the size of your typical engagements, and your risk tolerance. Standard limits are $1M per claim / $1M aggregate, but larger firms and higher-risk professions may need $2M–$5M or more.
Annual premiums typically range from $500–$3,000 for low-risk professions (general consultants, bookkeepers) to $5,000–$20,000+ for higher-risk professions (architects, engineers, financial advisors). Cost depends on revenue, profession, and claims history.
Claims-made policies cover claims filed during the policy period, regardless of when the incident occurred. Occurrence policies cover incidents that happen during the policy period, regardless of when the claim is filed. Most E&O policies are claims-made.
Yes, general liability does not cover professional errors or negligence. If your work involves providing advice, designs, recommendations, or professional services, you need separate E&O coverage. Many clients and contracts require it.
It covers defense costs and damages for claims of professional negligence, errors, omissions, misrepresentation, breach of duty, and failure to deliver services as promised. It typically covers both the cost of defense and any settlement or judgment.
Tail coverage (extended reporting period) allows you to report claims after a claims-made policy expires. You need it when switching carriers, retiring, or closing your business. Without it, claims from past work would be uncovered. It typically costs 100–200% of the final annual premium.
Revenue is a primary rating factor because higher revenue generally correlates with more clients, projects, and potential for claims. As your revenue grows, expect your premium to increase proportionally. Some carriers offer tiered pricing with discounts at certain revenue levels.
