How Much Does Errors & Omissions (E&O) Insurance Cost? [2026 Update]

Errors and omissions insurance cost depends on your profession, revenue, and risk profile. Errors and omissions (E&O) insurance, also called professional liability, protects your business if a client claims your work, advice, or a missed deadline caused them a financial loss. This 2026 guide breaks down errors and omissions insurance cost by industry, profession, and business size, and shows how to lower your premium.

Average Cost of E&O Insurance in 2026

Most small and midsize businesses fall into these ranges:

• Low-risk industries: $500 to $1,000 per year
• Most small businesses: $500 to $3,000 per year, with many professional service firms between $700 and $1,500
• Higher-risk industries: $3,000 to $12,000 or more per year

Actual pricing varies based on industry, revenue, employee count, coverage limits, and claims history.

What Affects the Cost of E&O Insurance?

• Type of industry. Your profession is the single biggest driver. Consulting and many service businesses sit at the low end; IT, marketing, media, and real estate are moderate; engineering, architecture, accounting, and finance carry the highest rates because their mistakes carry the largest financial consequences.
• Annual revenue. Higher revenue signals larger clients and more complex work, which raises premiums.
• Number of employees. More people doing professional work means more chances for an error, which raises exposure and premium.

Errors and Omissions Insurance Cost by Profession

Here is a quick errors and omissions insurance cost benchmark by profession, per year and per month:

Errors and Omissions Insurance Cost by Industry

Errors and omissions insurance cost varies most by industry, because the size of a potential mistake drives the price. Low-risk service businesses such as consulting and interior design sit at the bottom of the range, IT services, marketing, media, and real estate fall in the middle, and engineering, architecture, accounting, and finance carry the highest rates. In practice, low-risk industries pay roughly $500 to $1,000 per year, while the highest-risk fields run $3,000 to $12,000 or more.

E&O Cost for Small Business

For most small businesses, E&O insurance costs $500 to $3,000 per year, or about $40 to $250 per month, with many professional service firms landing between $700 and $1,500. The biggest factors are your revenue, employee count, and claims history. Most small businesses choose $1 million per claim and $1 million aggregate limits, which satisfies the majority of client contracts. Carriers frequently discount E&O when it is bundled with cyber liability and your general liability or business owners policy.

Average E&O Premium

The average E&O premium for a small professional services firm falls between $700 and $1,500 per year, though solo providers can pay as little as $300 and higher-risk firms much more. Because pricing swings so widely by profession and revenue, an average is only a starting point.

How to Lower Your E&O Premium

• Maintain strong documentation and use clear, current contracts
• Put quality-control steps in place and keep client communication tight so small disputes never become claims

• Bundle: carriers frequently discount E&O when it is written alongside cyber liability and your general liability or business owners policy
