Which business coverage belongs in your estimate?
Employees
Workers’ compensation commonly applies to employee injuries and is governed by state law. Employers’ liability is normally part of the workers’ comp policy. Requirements and owner treatment vary by state.
Premises, equipment, or inventory
Commercial property covers eligible physical assets. An eligible small business can use a BOP to package property, general liability, and usually business interruption coverage.
Customers or public interaction
General liability commonly addresses third-party bodily injury, property damage, and personal or advertising injury. Contracts and landlords often specify limits.
Advice or professional services
Professional liability / E&O addresses allegations that a professional error, omission, or service caused financial harm. It is separate from general liability.
Customer or employee data
Cyber insurance can respond to covered data breaches, cyber incidents, notification, recovery, and liability. Terms and security requirements vary materially.
Business vehicles
Commercial auto is not included in this calculator or a standard BOP. Business-owned vehicles generally need a commercial policy; hired and non-owned auto may matter when staff use personal or rented vehicles.

The size-and-region figures are calculator scenarios derived from published national and industry medians, not observed regional averages. Region multipliers are transparent budgeting assumptions (Midwest 0.95, South 1.00, Northeast 1.05, West 1.08); state-specific quotes can differ much more.
How to use the calculator
Choose your broad U.S. region and the closest industry or occupation.
Enter annual revenue, payroll, employee count, years operating, recent claim count, and property value.
Select several coverages. Choose either a BOP or separate general liability/property coverage to avoid duplication.
Select a desired liability limit and deductible preference. Open Advanced assumptions only when you know those values.
Calculate, review each policy subtotal and formula, test the what-if effects, then save scenarios A and B to compare designs.
Factors that affect business insurance price
Industry and work performed
Public interaction, physical work, products, professional duties, sensitive data, and historical loss patterns influence expected claim frequency and severity.
Revenue, payroll, people, and property
These are exposure measures. Workers’ comp normally uses payroll by class code; liability may consider sales, payroll, area, or other units; property starts with insured values.
Location and jurisdiction
State law, approved loss costs or rates, benefits, catastrophe exposure, litigation, taxes, and assessments can vary. This tool uses region only as a broad budget factor.
Limits and deductibles
More insurer-paid protection generally costs more. A higher deductible or retention can lower premium but increases the amount the business funds after a covered loss.
Claims and operating history
Insurers consider the type, timing, severity, and cause of losses—not merely the count. A new business may have less evidence of stable operations.
Controls and classification
Safety programs, contracts, cybersecurity, fire protection, construction, and accurate employee class codes can change underwriting and price. The simplified form cannot capture them all.
Formula and assumptions for each coverage
All formulas produce annual USD. “Published anchor” means the current Insureon national or industry median shown above. Exposure factors are intentionally dampened for policies that are not rated directly on a single input. Each result repeats its applicable formula.
Exposure: modeled revenue and employee scale. Limits use 1.00 at $1M/$2M and 1.02 at $2M/$4M, reflecting Insureon’s published $45 versus $46 medians. It is not a filed rate per $1,000.
Commercial property
Formula: $1,296 national annual anchor × insured-value factor × industry-property factor × region × claims × deductible × schedule.
Exposure: value of equipment, inventory, furniture, and owned building. Construction, protection, catastrophe zones, coinsurance, business income, and valuation basis are excluded.
Business Owner’s Policy
Formula: industry BOP anchor × blended revenue/property/employee factor × region × business-age × claims × limits × deductible × schedule.
Exposure: bundled liability and property. It is not added to separate GL/property. NAIC describes a BOP as a package that typically includes liability, property, and business interruption.
Workers’ compensation
Formula: (payroll ÷ $100) × derived industry benchmark rate × region × claims × experience modifier × schedule.
Base rate: each displayed industry median is calibrated at $50,000 payroll; for example, consulting $480/year ÷ 500 units = $0.96 per $100. Actual rating requires state and class-code rates. NCCI documents payroll ÷ $100 × class rate, then experience modification.
Exposure: revenue is a simplified proxy. Services, contracts, retroactive date, claim history, and claims-made terms matter. This is separate from cyber.
Exposure: revenue and people proxy data volume. Records, controls, prior incidents, vendors, ransomware controls, and business interruption needs are excluded.
Minimum, fees, assessments, and tax: after each coverage calculation, the optional minimum premium is applied. Package fees are added once. Assessment and tax overrides are shown separately and applied to premium. Defaults are zero because U.S. charges are jurisdiction- and policy-specific.
Worked business insurance cost examples
Solo consultant: BOP + E&O
Inputs: South, consulting, $120k revenue, $0 payroll, 0 employees, 6 years, no claims, $20k property, $1M/$2M limits, typical deductible.
Steps: GL $984 anchor × 1.33 revenue × 1.39 people × 0.95 region × 1.25 claim × 1.02 limit ≈ $2,199. Property $1,296 × 1.30 value × 1.35 industry × 0.95 region × 1.25 claim ≈ $2,704. Workers’ comp: 4,000 units × $6.096 × 0.95 × 1.25 = $28,956.
Estimate: about $33,859/year, or $2,822/month. Manual payroll and a prior claim dominate; actual class codes could move workers’ comp substantially.

Methodology, limitations, and editorial policy
Model scope: U.S. businesses with up to 500 employees and up to $100 million in revenue, payroll, or insured property. Results are annual USD budget estimates for the six listed coverages. The model does not determine eligibility, legal requirements, covered causes of loss, or policy wording.
Data and calibration
Insureon small-business insurance cost data, page reviewed July 18, 2026: national policy medians from 100,000 purchased policies and industry medians used as the primary anchors. Its general liability cost study, updated March 30, 2026, supplies observed state examples and the published $265–$3,030 annual GL span.
The Hartford $1 million liability cost, updated October 22, 2025: separate carrier-customer average used as a comparison point, not blended into the GL anchor.
NCCI, ABCs of Experience Rating, 2025: supports the workers’ comp payroll-per-$100, class-rate, and experience-mod structure. Calculator rates are derived benchmark anchors, not NCCI loss costs.
IRS Publication 334 (2025): qualified FAQ guidance on deductibility of business-related insurance premiums.
Assumptions and uncertainty
Industry GL/BOP/workers’ comp anchors use published medians where available; retail uses the national median because the source summary does not publish a directly comparable retail row. National property, E&O, and cyber medians are adjusted with disclosed heuristic factors. Region, exposure, age, claims, limits, deductible, and schedule factors are model assumptions—not regulator, bureau, or carrier rates. The low-to-high result applies a broad 0.60× to 1.80× interval to modeled premium before known fees and overrides. It is a planning interval, not a validated accuracy claim or confidence interval.
Exclusions
The model omits state/class-code detail, subcontractor cost, vehicle fleets, products/completed operations specifics, building construction and protection, catastrophe zones, business-income limits, retroactive dates, policy forms, endorsements, insurer minimums, installment charges, terrorism, surplus-lines taxes, and underwriting eligibility. Commercial auto is guidance-only and not priced.

Frequently asked questions
How accurate is this business insurance calculator?
It is a budgeting model, not a predictive quote engine. It starts with published U.S. policy medians, then applies transparent exposure and risk adjustments. The displayed low-to-high budget interval is deliberately broad and is not a statistical confidence interval.
Is this estimate an insurance quote?
No. Only a licensed insurer or producer can provide a quote after reviewing your state, class codes, operations, claims, limits, underwriting details, and eligibility.
What is the average monthly cost of small business insurance?
There is no single package average because businesses select different policies. Insureon's published medians include $45 per month for general liability, $83 for a BOP, $54 for workers' compensation, $88 for professional liability, $108 for commercial property, and $129 for cyber insurance.
How much does a $1 million general liability policy cost?
Insureon reports a $45 monthly median for the commonly selected $1 million per-occurrence and $2 million aggregate limit. The Hartford reports a $69 monthly average for its small-business customers with $1 million liability policies. Different statistics and customer groups explain why the figures should not be treated as identical.
Which business insurance coverage is required?
Requirements depend on the state, business, contracts, vehicles, and employees. Workers' compensation is required for many employers under state law, and business-owned vehicles generally need commercial auto coverage. Check your state insurance and workers' compensation agencies and your contracts.
Does a sole proprietor need business insurance?
A sole proprietor may still face customer-injury, property, professional, cyber, or contract risks. Workers' compensation treatment for owners varies by state, so confirm local rules even if the business has no other employees.
Are business insurance premiums tax deductible?
The IRS says premiums for several kinds of insurance related to a business, including liability and workers' compensation, can generally be deductible, subject to exceptions and timing rules. Ask a tax professional about your facts.
How can a business reduce insurance premiums?
Compare equivalent quotes, choose limits and deductibles deliberately, bundle eligible liability and property coverage in a BOP, maintain safety and cybersecurity controls, classify workers correctly, report claims promptly, and review values and exposures at renewal.
Can a BOP save money?
Often, but not always. A BOP packages liability, commercial property, and usually business interruption coverage; NAIC notes that it can cost less than buying policies separately. Eligibility and coverage vary, so compare like-for-like terms.
What is the difference between claims-made and occurrence coverage?
Occurrence coverage generally responds based on when the covered event happened, while claims-made coverage generally requires the claim to be made while the policy or applicable tail coverage is active. General liability is commonly occurrence-based; professional liability is commonly claims-made.
How do past claims affect business insurance cost?
Claims can increase an insurer's view of expected future loss and may affect eligibility, deductibles, limits, or price. This calculator applies a visible claims adjustment for budgeting, but insurers evaluate claim type, severity, timing, and corrective action in more detail.
