If you run a service business and you want one number to start with: most small firms pay somewhere between $40 and $145 per month for errors and omissions (E&O) insurance, with a common middle around $60 to $90 a month, or roughly $700 to $1,100 a year. A solo consultant with clean claims history and modest revenue can land near $35 a month. A financial advisor or engineer carrying real exposure can pay $135 a month or more. Those are typical ranges pulled from carrier and industry data, not a quote for your business. Your actual price depends on what you do, how much you bill, the limits you pick, and your claims record.
I write this as a licensed commercial-lines advisor in Hartford, and I quote E&O (the same product carriers also call professional liability) every week. The spread is wide because the risk is wide. A bookkeeper who fat-fingers a tax filing and a software developer who ships a bug that takes down a client’s storefront are buying the same category of coverage for very different stakes. This guide walks through the real numbers: average cost, cost by profession, what moves the premium up or down, how E&O stacks up against general liability, concrete ways to bring the price down, and how to read a quote so you know what you are actually buying.
What errors and omissions insurance actually pays for
Before the numbers make sense, it helps to know what you are paying for. E&O insurance covers claims that you made a professional mistake, gave bad advice, missed a deadline, or failed to deliver a service as promised, and a client lost money because of it. It pays for your legal defense and any settlement or judgment up to your policy limit, even when the claim turns out to be groundless. Defense costs alone can run into five figures, which is why a $60-a-month policy can be the cheapest insurance you ever buy if a dispute lands on your desk.
What it does not cover: bodily injury, property damage to other people’s stuff, or intentional wrongdoing. Those belong to general liability insurance, which is a separate product most service businesses also carry. The two are complements, not substitutes, and we will compare their costs below. According to the Insurance Information Institute, professional liability responds to claims of negligence, misrepresentation, and inaccurate advice, while general liability handles physical injury and property damage. Different risks, different policies, different prices.
Average errors and omissions insurance cost in 2026
Across small service businesses, the average E&O premium clusters in a fairly tight band once you strip out the extremes. Industry datasets put the typical small-business figure between roughly $60 and $90 a month. Carriers report that a large share of policyholders pay under $75 monthly, and a meaningful slice pay between $75 and $150. At the low end, a notary or a tax preparer with minimal revenue might pay $19 to $25 a month. At the high end, financial institutions and high-exposure professional firms can pay $200 a month or more.
Put another way, here is how the distribution tends to break down for businesses with a handful of employees:
- Solo operators (no employees): roughly $35 to $50 a month for standard limits.
- 1 to 4 employees: roughly $60 to $90 a month, the most common small-business range.
- 5 to 9 employees: roughly $72 to $110 a month.
- 10 to 19 employees: roughly $85 to $130 a month.
- 20 to 49 employees: $105 a month and up, often well into three figures.
These are typical ranges, not a guaranteed rate. Two firms with identical headcounts can be quoted very differently based on revenue, the kind of work they do, and where they operate. Treat the averages as a sanity check: if your quote lands far outside the band for your size and trade, ask why.
E&O insurance cost by profession
Profession is the single biggest driver of price, because it is a proxy for how much money a client can lose when you make a mistake. A bad haircut does not bankrupt anyone. A blown contract clause or a misfiled tax return can trigger a six-figure lawsuit. That gap is exactly what carriers are pricing.
The table below shows typical monthly and annual E&O ranges by profession for a small business carrying common $1 million limits. Figures are drawn from carrier and industry data for 2026 and represent typical ranges, not quotes. Your price will land where your revenue, services, location, and claims history put it.
| Profession | Typical monthly E&O | Typical annual E&O |
|---|---|---|
| Notary / tax preparer | $19 – $30 | $230 – $360 |
| Marketing consultant / agency | $40 – $60 | $480 – $720 |
| Bookkeeper | $40 – $55 | $480 – $660 |
| Real estate agent | $50 – $75 | $600 – $900 |
| IT / technology consultant | $55 – $80 | $660 – $960 |
| Management / business consultant | $50 – $80 | $600 – $960 |
| Accountant / CPA | $65 – $90 | $780 – $1,080 |
| Software developer | $65 – $95 | $780 – $1,140 |
| Insurance agent | $70 – $95 | $840 – $1,140 |
| Engineer | $120 – $160 | $1,440 – $1,920 |
| Financial advisor / planner | $120 – $160 | $1,440 – $1,920 |
Consultants and marketing firms
Consultants and marketing agencies sit on the lower-to-middle end, often $40 to $80 a month. A marketing consultant who advises on strategy carries less financial-loss exposure than one who manages a client’s ad spend and can be blamed for a wasted budget. The closer your advice sits to a client’s money, the higher the rate climbs. Management and business consultants land in roughly the same place, with the rate hinging on whether you produce deliverables a client can sue over or simply offer recommendations they choose to act on. If you take on interim operating roles, manage budgets, or sign off on financial models, expect to sit toward the top of this band. I have seen two consultants in the same vertical, billing similar revenue, quoted thirty dollars a month apart purely because one wrote implementation into the contract and the other did not.
IT and technology professionals
IT consultants and software developers typically run $55 to $95 a month. The fear carriers price for is downtime and data loss: a botched migration or a missed security patch can cost a client real revenue. Many tech firms bundle E&O with cyber liability, because the line between a professional mistake and a security failure is blurry, and a single incident can trigger both. Custom development and integration work tend to price higher than managed services or break-fix support, since custom code carries more room for an expensive defect. Larger client contracts also push the number up: a developer serving Fortune 500 clients faces bigger potential damages than one building sites for local businesses, and underwriters know it. If your contracts name specific clients with deep pockets, mention that when you quote, because it shapes the limits you will be expected to carry.
Real estate and insurance agents
Real estate agents commonly pay $50 to $75 a month, insurance agents $70 to $95. Both face claims tied to disclosure, paperwork, and advice. In several states E&O is effectively required to keep a license active, and some brokerages carry a master policy that agents pay into, which changes the math. Check whether you are buying your own policy or buying onto someone else’s.
Accountants and financial professionals
This is the priciest tier. Accountants and CPAs run $65 to $90 a month, while financial advisors and planners often pay $120 to $160 or more. The reason is simple: when these professionals get it wrong, clients can lose retirement savings or face IRS penalties, and the lawsuits are large. Financial-planning firms frequently pay two to three times what a personal-service business pays for the same limits. Within accounting, the work you take on matters: a bookkeeper handling data entry sits well below a CPA who signs audits or files complex returns, because a signed opinion is something a client and the IRS can both lean on when something goes wrong. Tax season raises the stakes further, since a single missed deadline or miscalculation can cascade across dozens of clients at once. If you offer fractional CFO services or investment advice on top of compliance work, your exposure stacks, and so does the premium. This is also the tier where higher limits stop being optional and start being a practical necessity.
What drives your E&O premium
Profession sets the baseline. After that, a handful of factors push your individual quote up or down. Understanding them is how you get from a sticker shock to a sensible number.
- Annual revenue and business size. More revenue means bigger potential claims, so premiums scale with it. Adding employees and growing sales can push your cost 50% to 80% higher than a solo version of the same business. Carriers usually ask for projected annual revenue, so quote it honestly.
- The services you actually perform. Two consultants in the same field get different rates if one only advises and the other executes work that can be blamed for a financial loss. Underwriters read your scope of services closely.
- Coverage limits. Moving from a $1 million limit to $2 million typically adds $20 to $40 a month. Higher limits cost more but are often required by client contracts, so the choice is not always yours to make.
- Claims history. A single prior professional liability claim can raise your rate 25% to 50% at renewal. A clean record is one of the cheapest discounts you have.
- Deductible. A higher deductible lowers your premium because you absorb more of a small claim yourself. The common average deductible sits around $2,500, but you can dial it up to cut the monthly cost.
- Location. Litigation-heavy states cost more. Businesses in high-litigation states can pay 30% to 35% more than the same firm in a quieter market.
- Experience and credentials. Years in the field, relevant licenses, and documented processes can all help your case with an underwriter.
None of these is a fixed formula. Carriers weight them differently, which is exactly why two quotes for the same business can vary by 40% to 60%. That variation is an opportunity, not a nuisance, and we will use it below.
E&O cost vs. general liability cost
People often assume E&O is the expensive one. In practice the two land in a similar neighborhood for most small firms, and which is pricier depends on your trade.
General liability for a typical small business with 1 to 4 employees runs around $40 to $125 a month, with a median near $45. E&O for the same size of business runs around $60 to $90 a month. For a low-risk office-based consultant, the two are close. For a contractor or a retailer with foot traffic, general liability can cost more because the physical-injury exposure is higher. For a financial advisor or engineer, E&O is usually the larger line item because the professional exposure dwarfs the slip-and-fall risk.
Most service businesses need both, and many buy them together. The U.S. Small Business Administration lists professional liability and general liability as separate core coverages precisely because they answer different claims. A common move is to package general liability with property coverage in a Business Owner’s Policy and add E&O alongside it. Bundling usually shaves 10% to 25% off the combined cost versus buying each policy standalone. For a full breakdown of how packaged pricing works, see our guide on business insurance cost and quotes.
How to lower your errors and omissions insurance cost
You have more control over this number than most people think. None of these tactics is a gimmick, and several can stack. Just remember that cutting coverage to cut cost can backfire if a claim exceeds your limit, so balance savings against the exposure you are actually carrying.
- Shop at least three carriers. Because quotes vary 40% to 60% for the same business, comparison shopping is the highest-use move available. Same risk, very different prices.
- Right-size your limits. If your client contracts only require $1 million, do not pay for $2 million out of habit. Carry what your contracts and exposure actually call for.
- Raise your deductible. Going from a $1,000 deductible to $5,000 can cut the monthly premium 20% to 40%, as long as you can comfortably absorb that amount if a small claim hits.
- Bundle policies. Combining E&O with general liability, property, or cyber under one carrier commonly saves 10% to 25%.
- Keep your claims record clean. Document your work, use clear contracts and engagement letters, and set client expectations in writing. Fewer claims means lower renewals.
- Use professional associations. Many trade groups offer member E&O programs, and association affiliation can knock 15% to 20% off in some cases.
- Pay annually if you can. Some carriers add a small fee for monthly installments. Paying the full year up front avoids it.
Discount percentages are typical and vary by carrier and state. A licensed agent can tell you which of these apply to your specific situation before you commit.
How to get an accurate E&O quote
A clean quote starts with clean inputs. The more precise you are, the closer the number is to what you will actually pay. Before you request quotes, have these ready:
- Your projected annual revenue for the coming year.
- A clear description of services, including anything that touches a client’s money or data.
- Your employee count, including contractors.
- The coverage limits your client contracts require, if any.
- Your claims history for the past five years.
- Your business location and the states you operate in.
When the quotes come back, read past the monthly price. Check the per-claim and aggregate limits (a $1M/$1M policy caps total annual payouts at $1 million, which is different from $1M per claim). Confirm whether it is a claims-made or occurrence policy. Claims-made is the norm for E&O and only responds while coverage is active, which matters if you ever switch carriers or close the business. Look for a retroactive date, which determines how far back covered incidents can reach, and ask about extended reporting (tail) coverage for claims that surface after a policy ends. Finally, confirm the deductible and whether it applies to defense costs. Two quotes at the same monthly price can differ enormously on these terms.

A worked example
Here is how the pieces come together in practice. Say you run a five-person marketing agency in Connecticut billing about $600,000 a year, with no prior claims, and a client contract requiring $1 million in E&O coverage.
Your baseline as a marketing firm puts you in the lower-middle tier, maybe $50 a month for a bare-bones solo profile. Add four employees and $600K in revenue, and the underwriter scales that up, call it 60% to 80% higher, landing around $80 to $90 a month for $1M/$1M limits. Your clean claims record keeps you at the favorable end of the range rather than the punitive one. Choosing a $2,500 deductible instead of $1,000 trims a few dollars. Bundling the E&O with a general liability and property package could shave another 10% to 15% off the combined bill.
The realistic landing spot: roughly $80 to $95 a month, or about $1,000 to $1,150 a year, for the E&O alone. If you also carry general liability, budget another $50 to $90 a month for that, often less when bundled. That is a worked illustration, not a quote. Move any one input, the revenue, the state, the limits, a single past claim, and the number moves with it. The only way to know your price is to get quotes on your actual business.
Frequently asked questions
How much does errors and omissions insurance cost per month?
Most small service businesses pay between $40 and $145 a month, with a common middle around $60 to $90. Solo, low-risk operators can pay near $35, while high-exposure professionals like financial advisors and engineers often pay $120 to $160 or more. These are typical ranges; your actual cost depends on your profession, revenue, limits, and claims history, so confirm with a licensed agent.
Is E&O insurance the same as professional liability insurance?
Yes. Errors and omissions insurance and professional liability insurance are two names for the same coverage. Both protect against claims that your professional work, advice, or service caused a client financial harm. Some industries favor one term over the other, but the policy does the same job.
What is the difference between E&O and general liability cost?
They land in a similar range for most small firms. General liability commonly runs $40 to $125 a month and covers bodily injury and property damage, while E&O runs about $60 to $90 a month and covers professional mistakes. Which is pricier depends on your trade. Most service businesses need both, and bundling them usually saves 10% to 25%.
Why is my E&O quote higher than the average?
Usually one of a few reasons: high revenue, a profession with large financial-loss exposure such as accounting or financial planning, higher coverage limits required by a client, a prior claim on your record, or operating in a high-litigation state. Each of these pushes the price above the baseline. A licensed agent can identify which factor is driving your number.
Can I lower my E&O premium without dropping coverage?
Yes. Shopping at least three carriers is the biggest lever, since prices vary widely for the same risk. Raising your deductible, right-sizing your limits to what your contracts require, bundling policies, keeping a clean claims record, and using an association program can all reduce the cost without leaving you underinsured. Weigh any savings against the exposure you carry.
