How Much Business Insurance Do I Need?

The wrong way to answer this is to pick a round number that feels safe. The right way is to ask a sharper question: what's the largest loss my business could realistically face, and who is contractually forcing my hand?

Coverage limits aren't a comfort setting. They're an engineering problem. Set them too low and a single large claim blows past your policy and reaches your business assets. Set them too high without reason and you pay for protection you'll never use. The goal is to size the policy to the actual exposure.

Start with what others require, not what you prefer

Before you decide what you want, find out what you're obligated to carry. These requirements usually dictate your floor:

• Leases — most commercial landlords require general liability of at least $1 million per occurrence and name themselves as an additional insured.
• Client contracts — many require specific limits and a certificate of insurance before work starts. Some require professional liability or higher general liability than you'd otherwise buy. Here's why clients ask for proof of insurance.
• Lenders — if you financed equipment or property, the loan agreement likely mandates coverage.
• State law — workers' compensation limits are set by statute, not by you. See workers' comp requirements.

A surprising amount of "how much do I need" is already decided for you. Map these first.

Then size to your worst realistic loss

For everything not dictated by a contract, the question is: what's the most this could cost if it went badly? Run it line by line.

• General liability — the standard is $1 million per occurrence / $2 million aggregate, but a business with heavy foot traffic, physical work on client property, or higher-value clients often needs more. How much GL is enough?
• Commercial property — insure to replacement cost, what it costs to rebuild and re-equip new, not the depreciated value or the market price. Under-insuring property triggers coinsurance penalties that cut your payout. Understand property limits.
• Business interruption — size it to the revenue and fixed costs you'd lose during a realistic shutdown, including the months it takes to fully reopen, not just the days you're closed. How business interruption coverage works.
• Professional liability — size to the financial damage a mistake in your work could cause a client, which is often far larger than your fee.

Think of limits like the load rating on a bridge. You don't build it for the average car — you build it for the heaviest truck that will ever realistically cross. Insurance is the same: you size it to the worst plausible event, not the typical day.

The role of an umbrella policy

When your underlying limits feel adequate for routine claims but exposed to a true catastrophe, a commercial umbrella adds excess liability on top of your general liability, commercial auto, and employer's liability — often a large amount of additional coverage for a modest premium. It's how a small business affordably protects against a six- or seven-figure judgment that would otherwise reach everything it owns.

Don't set it and forget it

The right amount today is wrong in two years. Coverage needs drift as you add employees, sign bigger clients, buy equipment, open a location, or change what you do. A business that quietly grows past its limits is underinsured without ever getting a warning — the policy doesn't flag it; the claim does. Signs your business is underinsured.

This is the case for reviewing coverage at least once a year and after any major change. How often should you review your insurance?

A simple way to pressure-test your limits

For each policy, finish this sentence: "If the worst covered event happened tomorrow, this limit would leave me exposed for $______." If that blank is a number that would damage the business, your limit is too low. If it's comfortably zero with room to spare, you may be over-buying.
