Small business insurance costs $500 to $6,000 a year for most companies. The spread is driven by what you do, how many people you employ, and how much payroll runs through the business. Most new owners budget for formation and equipment, then discover insurance when a landlord, a client contract, or state law demands proof of coverage before they can sign.
Quick Cost Summary

Detailed Cost Breakdown
General liability: $45/month average
Covers third-party bodily injury, property damage, and advertising injury. It is the policy a landlord or a client asks for by name.
Price tracks the odds that someone gets hurt around your work. Low-risk businesses like consulting and freelancing land near $300 to $600 a year. Medium-risk trades like cleaning and landscaping run $500 to $1,200. High-risk operations like restaurants and construction pay $1,500 to $5,000 or more. Same coverage, different probability of a claim.
Workers' compensation: $45 to $70/month median
The monthly median hides the mechanism. Workers' comp is not priced per employee. It is priced per $100 of payroll, at a rate set by your state and your employees' class codes. A rough range is $2 to $4 per $100 of payroll, so a business with $300,000 in payroll pays roughly $6,000 to $12,000 a year. An office of software developers and a roofing crew with identical payroll pay wildly different premiums, because one class code falls off roofs.
Rates are set at the state level. Move a crew across a state line and the premium changes without anything else changing.
Business owner's policy: $83/month average
A BOP bundles general liability with commercial property into one policy. Among Insureon customers, 25% pay under $50 a month and another 33% pay between $50 and $100 (Insureon, 2025). Annual premiums run from roughly $400 to over $6,000.
If you have a storefront, an office, or meaningful equipment, price the BOP before you price the pieces. Bundling is usually cheaper than buying general liability and commercial property separately, which is the rare case where the bundled product is not the worse deal.
Professional liability (errors and omissions): $60/month average
Covers the claim that your advice or your deliverable cost the client money. General liability does not. If you are paid to think, this is the policy that matters, and higher-risk professions such as engineers and medical consultants pay above the average.
What Drives the Price
Industry risk. The single largest factor. A general contractor and a financial services firm buying identical general liability limits pay very different premiums, because the underwriter is pricing the probability of a claim, not the paperwork.
Payroll. Workers' comp scales directly with it. Revenue does not enter the formula.
State. Workers' comp rates are state-set. Liability pricing moves with local litigation and weather exposure.
Claims history. Two or three claims and you are shopping in a smaller market at a worse price.
Limits and deductible. A $1M/$2M limit is the contract default. Raising the deductible lowers the premium and moves the small losses onto your balance sheet, which is the correct trade only if the balance sheet can take it.
Bundling Saves Money
A BOP combining general liability and commercial property almost always costs less than the same two policies bought separately, because the insurer prefers to write both. If a broker quotes them apart without mentioning a BOP, ask why.
What a BOP does not include: workers' comp, commercial auto, and professional liability. Those are separate purchases, and a "we're fully covered" belief built on a BOP alone is the expensive kind of wrong.
When You Are Legally Required to Have It
Workers' compensation is mandatory in nearly every state the moment you have employees. Texas is the notable exception for most private employers, and even there, going without it strips your defenses in an injury suit. Penalties elsewhere range from per-day fines to criminal exposure for willful non-coverage.
Commercial leases and client contracts create private mandates. Most commercial landlords require proof of general liability before handing over keys. Most enterprise client contracts require it, at stated limits, plus an additional-insured endorsement naming the client. Both are contract terms, not law, and both will stop a deal cold.
Commercial auto is required by state law once a vehicle is titled to the business. A personal auto policy does not cover a vehicle used for business.
If you need coverage quickly to sign a lease or a contract, Next Insurance issues certificates of insurance same-day for most small business classes.
What Most People Forget
Certificates of insurance are free, and clients will ask for them constantly. Additional-insured endorsements sometimes are not. Cyber liability is not in a BOP and matters the moment you store customer data. Employment practices liability covers the wrongful-termination suit that a general liability policy will not touch. And coverage lapses the day you miss a payment, which is the day the claim arrives.

Frequently Asked Questions
How much does small business insurance cost per month?
General liability averages $45 a month, a business owner's policy averages $83 a month, professional liability averages about $60 a month, and workers' compensation runs a median of $45 to $70 a month (Insureon, 2025). A typical small service business carrying general liability and professional liability pays roughly $100 a month.
Is workers' compensation required by law?
In nearly every state, yes, from the moment you have employees. Texas is the notable exception for most private employers. Rates are set per $100 of payroll by state and employee class code, which is why two businesses with the same headcount can pay very different premiums.
Is a business owner's policy cheaper than buying separately?
Usually. A BOP bundles general liability and commercial property and typically costs less than the same two policies purchased apart. It does not include workers' comp, commercial auto, or professional liability.
Why does my quote differ so much from the average?
Because industry risk dominates every other factor. Underwriters price the probability of a claim. A consulting firm and a roofing contractor buying identical limits are not buying the same risk, and the premium reflects that rather than the paperwork.
Do I need insurance before I have employees or customers?
Usually not by law, but almost always by contract. Commercial landlords require proof of general liability before lease signing, and most business clients require it at stated limits before work begins. The trigger is the contract, not the revenue.
