Short answer

E&O Insurance Cost Calculator

$2,000Estimated annual premium

E&O pricing scales sub-linearly with limits — doubling coverage from $1M to $2M costs roughly $1,138 more, not double. Clients requiring certificates of insurance often set the limit, not you.

How it's calculated: $167/mo for $1,000,000 of E&O coverage on $250,000 revenue. Adjust the inputs below to recalculate for your own numbers.

Disclaimer: Estimates only — not insurance, tax, or legal advice. Actual premiums depend on underwriting, state, carrier, claims history, and plan details. Confirm numbers with a licensed agent, broker, or Healthcare.gov before acting.

Formula used

Premium = revenue × profession rate × limit factor

E&O covers claims that your professional work caused a client financial loss — missed deadlines, bad advice, errors in deliverables. Rates are driven by profession risk (advice-heavy fields pay more), revenue, and claims history.

E&O premium ≈ revenue × base rate × (limit ÷ $1M)^0.65

Who actually needs E&O

Anyone paid for advice or professional services where a mistake costs the client money: consultants, agents, accountants, designers, IT professionals. General liability covers bodily injury and property damage — it does NOT cover financial loss from your work product, which is the far more common claim.

  • Claims-made policies: you need continuous coverage (or tail coverage) to stay protected.
  • Many contracts require $1M E&O before you can start work.
  • Defense costs count toward the limit on some policies — check 'defense outside limits'.

FAQ

How much does E&O insurance cost for a consultant?

A solo consultant with $150K revenue typically pays $600–1,500/year for $1M of coverage. Higher-risk professions (financial advisors, engineers) pay 2–4× more.

Is E&O the same as professional liability?

Yes — different names for the same coverage. 'E&O' is common in insurance, real estate, and finance; 'professional liability' and 'malpractice' (medical) elsewhere.

What does E&O not cover?

Intentional wrongdoing, criminal acts, bodily injury (that's general liability), employee lawsuits (EPLI), and cyber incidents (cyber liability). E&O is strictly for financial-loss claims arising from your professional services.
