Business insurance is not optional—it's a fundamental risk management tool that protects your personal assets, satisfies contract requirements, and ensures you can survive a major claim. One uninsured lawsuit can bankrupt a business, and most commercial leases and client contracts require proof of coverage.
The right insurance mix depends on your industry, revenue, employee count, and risk profile. General liability is the foundation for most businesses, but you may also need professional liability (E&O), cyber coverage, workers' comp, and property insurance. The calculators below help you estimate costs and plan your insurance budget.

Step-by-step workflow
Estimate general liability insurance
General liability (GL) covers third-party bodily injury, property damage, and advertising injury. It's required by most landlords and clients, and typically costs $500–$3,000/year depending on industry and revenue. Start here for your first premium estimate.
Assess professional liability needs
If you provide advice, consulting, or professional services, you need professional liability (E&O) insurance. It covers claims of negligence, errors, or failure to deliver. Rates vary widely by profession—lawyers and architects pay much more than IT consultants.
Evaluate cyber insurance coverage
If you store customer data, process payments, or rely on digital systems, cyber insurance is critical. It covers breach response, legal fees, notification costs, and business interruption. Premiums start around $1,000–$3,000/year for small businesses.
Calculate total insurance budget
Add up all required policies: GL, professional liability, cyber, workers' comp (if you have employees), commercial property (if you own equipment/inventory). Total insurance often runs 1–3% of revenue, but it's a small price for protection.
Average annual insurance premiums by policy type
These are national averages for small businesses ($500K–$2M revenue). Your actual premium depends on industry, claims history, coverage limits, and location.
Common mistakes to avoid
Buying only the minimum required coverage
The minimum limits required by contracts ($1M general liability) are often inadequate. A serious claim can easily exceed $1M. Consider $2M or $5M limits—the marginal cost is small relative to the extra protection.
Assuming general liability covers everything
General liability does NOT cover professional mistakes (you need E&O), cyber breaches (you need cyber insurance), employee injuries (you need workers' comp), or your own property (you need commercial property insurance). Each coverage is separate.
Not shopping rates annually
Insurance premiums vary significantly by carrier. Get 3–5 quotes every renewal, and consider working with an independent broker who can compare multiple carriers on your behalf.
Key financial considerations
- → General liability covers third-party bodily injury, property damage, and advertising injury—it's required by most leases and client contracts.
- → Professional liability (E&O) protects against claims of negligence, errors, or failure to deliver services—essential for consultants, contractors, and advisors.
- → Cyber insurance is critical if you handle customer data or process payments—it covers breach response, legal fees, notification, and business interruption.
- → Workers' compensation is required in most states as soon as you hire—rates vary 30× between office workers and roofers, so get accurate class code quotes.
- → Consider a Business Owner's Policy (BOP) that bundles general liability + commercial property—often cheaper than buying policies separately.
