Annual E&O coverage costs for small business owners range from $400 to over $7,000. 43% of TechInsurance customers pay less than $75 per month for their E&O coverage, while another 28% pay between $75 and $150 monthly.
Your unique risks and the type and amount of coverage you choose can impact your policy rates.

Here are the top factors that impact your errors and omissions insurance costs:
The cost you pay for errors and omissions insurance (also known as professional liability insurance or malpractice insurance) depends on your coverage limits. Most small business owners (56%) opt for an E&O policy with a $1 million per-occurrence limit and a $1 million aggregate limit.
11% of TechInsurance customers select the next most popular choice: a policy with $2 million/$2 million limits.
For some professionals, such as real estate agents, your state laws will determine the amount of coverage you need.
Businesses that offer professional services or advice that affects a client's income should consider higher policy limits as they’re more susceptible to client lawsuits. Higher limits cost more, but they cover more expensive claims.
E&O liability coverage helps protect against client lawsuits arising from the quality of work, such as missed deadlines, errors, or accusations of negligence. This includes legal costs, such as attorney fees.
If you need E&O coverage beyond the standard policy limits, you can carry excess liability insurance to increase these limits. Excess liability coverage starts once you’ve exhausted the limits of your primary E&O policy.
This policy provides an additional layer of protection for higher-risk businesses; however, the higher your total coverage limit, the more risk your insurance provider is taking on, which increases your rates.
Consult a TechInsurance agent if you have questions about the right coverage for your needs.

Your specific industry can impact how much you'll pay for your errors and omissions coverage. High-risk professions generally pay significantly more than low-risk ones.
Examples of industries and how much they pay include:
Other professionals, including healthcare professionals and lawyers, may be required to carry E&O coverage to obtain licensure or to sign a client contract.
Even if it's not legally required, E&O coverage is highly recommended since it can help protect your business from costly legal fees arising from professional blunders, missed deadlines, or perceived negligence.
The following chart outlines how E&O insurance costs can vary based on your profession:
E&O insurance by itself won't protect you if a client sues over a cyberattack that results in a data breach. However, it's often bundled with cyber liability insurance in a package called technology errors and omissions insurance, also referred to as tech professional liability insurance.
Tech E&O coverage costs depend on the amount of data and the number of employees who can access it. The more people in your company who have access to sensitive data, the greater the chance of a data breach.
For example, large cybersecurity companies and businesses with sensitive digital assets would pay more for their tech E&O policy than a smaller technology company with fewer employees.
Your E&O coverage costs can be impacted by your business location. Insurance providers factor in location when determining your risks and establishing premium rates. Some areas may have state-specific policy requirements or greater legal costs.
California and New York businesses, for example, may face higher premiums than those in other regions due to the business environment, including legal and historical claim trends.
If your business has locations in several states or serves clients in multiple jurisdictions, your policy price and structure may also be impacted.
The following table shows how the cost of E&O insurance varies across states:
Insurance companies evaluate your claims history to establish how risky your business is to insure. Companies with a history of errors and omissions claims will pay more than those without.
Risk management is critical to keeping your insurance costs down. Small businesses without a history of claims often benefit from lower rates and other discounts.
Minimize risks at your workplace through strict protocols, employee training, safe business practices, and documented communications with clients. These risk management strategies can help keep your overall insurance costs lower.
The more employees you have, the more opportunities there are for a client to file a lawsuit. Larger workforces can increase the likelihood of miscommunications, mistakes, and incidents that lead to E&O claims.
While errors and omissions insurance is recommended for many small businesses, most state laws require small business owners to carry workers' compensation if they have employees, and commercial auto insurance if they have business-owned vehicles.
If you are a freelancer, independent contractor, or sole proprietor, it's still a good idea to carry E&O coverage to protect yourself from the high costs of legal defense.
Higher annual business income often leads to higher errors and omissions liability premiums for most small businesses.
The bigger the size of your business and the more contracts and clients you take on, the more likely you or your employees are to make an error or commit an accident, which could lead to a lawsuit and a subsequent insurance claim.
Smaller companies with lower revenue often have lower E&O insurance costs.
Growing your business and taking on more jobs, contracts, and employees can increase professional liability insurance rates.
Errors and omissions insurance is a crucial coverage option for businesses that provide expert advice or specialized services.
Seasoned professionals can still make errors, oversights, or gaffes and may provide guidance that causes financial loss for their clients. If the client sues, legal expenses and settlements can escalate to the point where they could sink your business.
Even if you or your employees have done nothing wrong, you could still face a costly lawsuit. For example, your business could fall behind on a projected deadline due to no fault of your own or your team, or a client could sue over scope creep that was out of your hands.
Lawsuits are exceptionally expensive, even frivolous ones. If you lose the lawsuit, you could end up paying a significant amount in a court-ordered judgment or a settlement.
Errors and omissions insurance covers legal expenses related to lawsuits, and because the premium is based upon your level of risk and your industry, many small businesses pay a fairly low amount for this type of insurance.
It’s easy to save money on your errors and omissions insurance policy without compromising coverage.
Some strategies to keep costs down include:
A good risk management strategy to reduce E&O claims includes:
You can’t eliminate risk. If that were possible, insurance companies would be out of business. But risk management helps you sidestep common pitfalls that lead to liability claims and higher errors and omissions (or professional liability) insurance costs.
