This business insurance calculator gives small business owners a quick, editable estimate of what a year of coverage might cost, broken down across general liability, commercial property, and a bundled business owner's policy (BOP), based on your revenue, industry risk, headcount, and property value.
Arb Digital built this tool because most small business owners we work with have never seen a line-item breakdown of what drives their insurance quote — they just see one number from a broker. Plugging your own figures in here gives you a starting point before you request real quotes.
What This Business Insurance Calculator Does
You enter your annual revenue, pick an industry risk tier, add your employee count and the value of your commercial property or equipment, then choose which coverage types you want estimated. The calculator computes an illustrative premium for each selected coverage type, applies a bundling discount when all three are combined into something resembling a BOP, and totals everything into one estimated annual premium. It's meant to help you budget and compare, not to replace an actual application with a licensed commercial insurance agent or broker.
How to Use It
- Enter your annual revenue. Insurers use revenue as a proxy for exposure — more revenue generally means more transactions, more customer interactions, and more liability risk.
- Choose your industry risk level. A quiet consulting office carries very different risk than a construction crew or a commercial kitchen.
- Enter your employee count. More employees typically means more liability exposure and higher premiums, even before you add workers' compensation into the picture.
- Enter your property or equipment value. This drives the commercial property coverage estimate.
- Select which coverages to include and click Calculate to see your estimated annual premium and its breakdown.
The Formula / How It's Calculated
General liability in this calculator is estimated from a small fixed base amount plus a component scaled to your revenue and a component scaled to your employee count, all multiplied by your industry risk factor — low-risk office businesses use a 0.8 multiplier, medium-risk retail and hospitality businesses use 1.0, and high-risk construction and manufacturing businesses use 1.6. Commercial property coverage is estimated as a percentage of your entered property value, also adjusted by industry risk, since a high-risk facility tends to carry a higher property rate too. If you select the BOP bundle, the calculator adds a coverage layer for things like business interruption and equipment breakdown, and then, if all three coverage types are selected together, applies roughly a 10% bundling discount to the combined total — reflecting how real BOPs are typically priced cheaper than buying general liability and property as fully separate policies.

General Liability vs. Property vs. a BOP
General liability insurance protects your business against claims of bodily injury, property damage, and advertising injury caused to third parties — think a customer slipping in your storefront or a contractor accidentally damaging a client's property. Commercial property insurance, by contrast, protects your own physical assets: your building if you own it, your leasehold improvements if you rent, your equipment, inventory, and furniture, against risks like fire, theft, and certain weather events. A business owner's policy, or BOP, is a packaged product that combines general liability and commercial property into a single policy, often at a lower combined cost than buying each separately, and frequently adds business interruption coverage that replaces lost income if a covered event forces you to temporarily close. Most BOPs are designed for small and mid-sized businesses under a certain revenue threshold and a certain employee count, so very large or very high-risk operations sometimes need to buy the coverages separately or add specialized endorsements.
Coverage Types Every Small Business Should Understand
Beyond general liability, property, and BOP coverage, most growing businesses eventually need to think about professional liability (errors and omissions) if they give advice or perform services, cyber liability if they store customer data, commercial auto if employees drive for work, and workers' compensation as soon as they hire staff — which is required in nearly every state once you have even one employee. Product liability coverage matters if you manufacture or sell physical goods, since a defective product claim can be far more expensive than a typical slip-and-fall claim. Umbrella or excess liability policies sit on top of your other coverage and kick in once the underlying policy limits are exhausted, which many landlords, lenders, and larger clients now require before they'll sign a contract with a small business.
What Actually Moves Your Premium
Underwriters look well beyond the inputs in this calculator. Claims history matters enormously — a business with prior liability or property claims will typically see higher rates than a comparable business with a clean claims record. Location matters too, since crime rates, weather exposure, and local building codes all factor into property rates. Your years in business, your safety programs, deductible choices, and the specific policy limits you select all shift the final number. Businesses that carry higher deductibles in exchange for lower premiums, or that bundle multiple policies with the same carrier, often see meaningfully better pricing than businesses that shop each coverage separately every renewal.
- Claims-free businesses typically qualify for renewal discounts over time.
- Higher policy limits and lower deductibles both raise your premium.
- Some industries (like food service or contracting) require specific endorsements not included in a base BOP.
- Multi-policy discounts are common when you bundle general liability, property, auto, and workers' comp with one carrier.
Worked Example: How Industry Risk Changes the Number
Run the calculator's defaults — $500,000 in annual revenue, 5 employees, $200,000 in property value, all three coverages selected — at each of the three industry risk tiers and you can see how much that single dropdown swings the estimate. A low-risk professional services business lands around $1,748 a year. The exact same revenue, headcount, and property, moved into the medium-risk retail and hospitality tier, comes out to roughly $2,185 — about 25% more. Push the same business into the high-risk construction and manufacturing tier and the estimate jumps to around $3,496, nearly double the low-risk figure, even though nothing changed except the industry classification. That gap is a useful gut check when you're comparing quotes from different brokers: if two agents give you wildly different numbers for the same business, ask which risk classification code (called a class code) each one used, because that single input often explains more of the price difference than any policy limit or deductible choice.
How Location and State Requirements Change Your Costs
This calculator intentionally doesn't ask for your state, because state-level rating factors are too complex to model with a simple multiplier — but they matter enormously in a real quote. States with higher litigation rates, higher construction costs, or more frequent severe weather (hurricanes along the Gulf Coast, wildfire zones in parts of California, hail corridors through the Midwest) generally see higher commercial property rates than states without those exposures. Workers' compensation, which this tool deliberately excludes, is regulated entirely at the state level, with wildly different rate schedules, required minimum coverage, and even different rules about whether owners themselves must be covered. Business license and permit requirements can also trigger minimum liability limits you wouldn't guess from the calculator alone — many cities require a $1 million general liability minimum just to pull a contractor's permit or lease certain commercial spaces, regardless of what a generic premium estimate suggests you need.

- Under-insuring property value. Using outdated replacement cost figures leads to a coinsurance penalty at claim time.
- Skipping professional liability when your business gives advice, designs, or performs services, since general liability doesn't cover errors and omissions claims.
- Assuming a BOP covers everything. Cyber liability, workers' comp, and commercial auto are almost always separate policies.
- Not updating coverage as revenue grows. A policy sized for a $200,000 business won't protect a $2 million business.
- Choosing the cheapest quote without checking the exclusions, sub-limits, and deductibles in the fine print.

Frequently Asked Questions
Requirements vary by state and industry, but workers' compensation is mandatory in nearly every state once you have employees, commercial auto is required if you operate vehicles, and many landlords or clients contractually require general liability coverage even where it isn't legally mandated.
General liability alone only covers third-party bodily injury, property damage, and advertising injury claims. A business owner's policy (BOP) bundles general liability with commercial property coverage and often business interruption coverage, usually at a lower combined price than buying each separately.
Yes. Revenue is a common proxy insurers use for the volume of customer transactions and overall liability exposure, so higher-revenue businesses typically pay more for the same coverage type than lower-revenue businesses in the same industry.
Most BOPs are designed for small to mid-sized businesses under certain revenue and employee thresholds set by each insurer. Larger or higher-risk operations may need to purchase general liability and property coverage as separate policies instead.
No. Workers' compensation is priced separately based on payroll, job classification codes, and your experience modification factor — use our dedicated Workers' Comp Calculator for that estimate.
Common strategies include bundling coverage with one carrier, raising your deductible, maintaining a clean claims history, installing safety and security systems, and reviewing your coverage annually as your revenue and risk profile change.
