Errors & Omissions Insurance Consultant 2027 Calculator

E&O (Errors & Omissions) insurance is mandatory in most B2B consulting contracts. This 2027 calculator estimates annual premium for management, IT, HR, marketing, and strategy consultants based on revenue, claim history, and policy limits.

Why Consultants Need E&O Insurance

Consulting deliverables are intangible. When a client believes your strategy, code, recommendation, or training caused them financial loss, they sue. E&O covers defense costs (often $50K-$300K even on dismissed claims), settlements, judgments. Without E&O, one suit can end your firm. Most B2B MSAs now require $1M-$2M proof of coverage before signing — coverage gates revenue.

How Premium Is Priced In 2027

Carriers (Hiscox, CNA, Travelers, AIG, Berkshire Hilltop) use these factors: revenue (the biggest), specialty (IT > strategy), claim history (one prior claim = 25-60% surcharge), policy limits, deductible, retroactive date (more retro = more premium), number of consultants. Solo consultants in low-risk fields can pay as little as $400-$700/year; small IT firms easily clear $5,000.

E&O vs General Liability vs Cyber

E&O: claims your advice caused financial harm. General Liability: bodily injury or property damage (slip-and-fall, broken equipment). Cyber: data breach, ransomware, regulatory fines. A consultant needs all three. Bundle E&O with GL via a Tech E&O or Miscellaneous Professional Liability package — most carriers save 10-15% on bundled premiums.

What To Look For In The Policy Wording

Pricing is one part — but coverage wording matters more. Look for: defense outside limits (defense costs don't erode the per-claim limit; rare but valuable), worldwide coverage (matters if you work with international clients), prior-acts coverage back to your business start date (or buy nose coverage when switching carriers), spousal coverage (defends spouse named in a claim), independent contractor coverage (your subs covered while working under you), regulatory defense for state professional board investigations. Cheap policies often strip these.
