Quick answer: Most small businesses pay between $500 and $3,000 per year for errors and omissions insurance, or roughly $40 to $250 per month. Low risk professions often land between $500 and $1,000 per year, while higher risk fields such as engineering, architecture, finance, and accounting commonly run $3,000 to $12,000 or more. Your industry, revenue, claims history, and limits drive the final number.
Errors and omissions (E&O) insurance, also known as professional liability insurance, protects your business if a client claims you made a mistake, gave inaccurate advice, missed a deadline, or did not deliver a service as expected. Even when you have done everything right, defending a claim can quickly become expensive. Here is the updated 2026 breakdown of what E&O costs and what moves the price.
Most small and midsize businesses fall into these ranges:
Actual pricing varies based on industry, revenue, employee count, coverage limits, and claims history.
1. Type of industry. Your profession is the single biggest driver. Consulting, interior design, and many service businesses sit at the low end. IT services, marketing, media, and real estate are moderate. Engineering, architecture, accounting, and finance carry the highest rates because their mistakes carry the largest financial consequences.
2. Annual revenue. Higher revenue signals larger clients and more complex work. With higher financial stakes, premiums increase.
3. Number of employees. More people doing professional work means more chances for an error, which raises exposure and premium.
4. Geographic location. Businesses in major metro areas or states with heavy litigation activity usually pay more. Suburban and rural businesses tend to see lower rates.
5. Years in business. Newer businesses often pay more at first. A longer track record with stable operations improves pricing.
6. Claims history. Even one past allegation, whether paid or dismissed, can raise your premium. A clean loss history keeps rates down.
Maintain strong documentation, use clear and current contracts, put quality control steps in place, choose a deductible aligned with your risk tolerance, and keep client communication tight so small disputes never become claims. Bundling also helps: carriers frequently discount E&O when it is written alongside cyber liability and your general liability or business owners policy.
Your exact premium depends on industry, revenue, employee count, claims history, states of operation, coverage limits, and any contract or client requirements. Many Pro Insurance Group clients land between $40 and $250 per month depending on business size and risk profile. A precise number requires a personalized quote, and as an independent broker we shop multiple carriers to find the best fit.

In some professions, yes. Real estate agents, insurance producers, and certain financial roles are required by law or licensing boards to carry E&O in many states. Even when it is not legally required, client contracts frequently demand proof of coverage before work begins, which makes it effectively mandatory for most professional service firms.
Most small businesses choose $1 million per claim and $1 million aggregate limits, which satisfies the majority of client contracts. Businesses with larger contracts, bigger clients, or higher risk work often carry $2 million or more. Check your client agreements first, since required limits are usually spelled out there.
It varies by carrier. Some policies extend coverage to subcontractors working on your behalf, while others require each subcontractor to carry their own E&O policy. If you rely on subcontractors, confirm how your policy treats them and collect certificates of insurance before work starts.
The retroactive date is the earliest date of work your policy will cover. E&O is claims made coverage, so a claim is only covered if the work happened after the retroactive date and the claim is reported while the policy is active. When switching carriers, preserving your original retroactive date is critical to avoid a gap.
Yes. A clean claims history, strong internal processes, and steady operations all improve pricing at renewal. Working with an independent broker also helps, since carriers compete differently for mature, low claim accounts and remarketing your policy periodically keeps your rate honest.
No. E&O covers honest mistakes, oversights, and negligence in your professional work. Intentional acts, fraud, and criminal conduct are excluded across the market, and so are bodily injury claims, employee injuries, and data breaches, which belong to other policies.
