General liability insurance calculator

General liability is rated on exposure — receipts and payroll — multiplied by a rate that follows what you actually build. This shows how far the class of work moves the number, and what buying higher limits costs.

§ 1What this estimates

The annual premium for a commercial general liability policy, as a band. It does not estimate whether your policy will respond to a given claim — that is a wording question, and the exclusions are in our general liability guide.

§ 2How to use it

  1. § 1Set the class of work to what you actually do most. Understating it produces a cheaper number here and an argument at claim time.
  2. § 2Enter receipts and payroll. Include subcontracted labour — carriers do.
  3. § 3Choose the limits your contracts demand, not the smallest ones available.

§ 3Worked example

Two contractors, same receipts, same payroll, different trades. The class of work is doing almost all of the work in that difference — which is why an accurate class code is the most valuable line on the application.

§ 4State notes

California is the state where a limit is not purely a commercial decision. A licensed LLC must carry a cumulative limit of at least $1,000,000, increasing $100,000 per additional person of record up to $5,000,000, under B&P Code § 7071.19 — and since 2014-01-01 the policy must be written by an admitted carrier.
