General Liability Premium Calculator

Estimate general liability insurance premiums based on revenue, payroll, industry classification, and coverage limits.

About this calculator

This calculator estimates general liability premium from two separate components added together: a revenue-based charge (Annual Revenue times a per-$1,000 rate that depends on Industry Risk Level) and a payroll-based charge (Annual Payroll times a flat rate that steps up for higher-risk industries). Those two components are then scaled by three multipliers -- a Coverage Limit factor (higher limits cost more), a Deductible factor (a higher deductible earns a discount, since you're absorbing more risk yourself), and a Years in Business factor (established businesses get a lower rate, reflecting a track record with fewer unknowns). Industry Risk Level is the single most consequential input in this formula -- it sets the per-$1,000 revenue rate directly (ranging from $2.50 for low-risk office work up to $18 for hazardous operations, a more than 7x spread) and also determines whether the higher or lower payroll rate applies, so misclassifying your industry produces a bigger swing in the estimate than any other single input.

The deductible discount and experience discount are both step functions rather than smooth curves -- moving from a $1,000 to a $2,000 deductible produces no discount at all, since the discount tiers only activate at $2,500 and $5,000, so small deductible changes near those thresholds can look deceptively flat. This is a simplified estimate, not a quote -- real general liability pricing incorporates claims history, specific operations, geographic location, and carrier-specific underwriting that this calculator cannot see.

How to Use This Calculator
  1. Enter your Annual Revenue and Annual Payroll.
  2. Select your Industry Risk Level — Low (office/consulting), Medium (retail/service), High (construction), or Very High (hazardous).
  3. Set your desired Per-Occurrence Limit and Deductible.
  4. Enter Years in Business to apply any experience discount.
  5. Review the estimated Monthly and Annual Premium, then get competitive quotes from at least three carriers before binding coverage.

Frequently Asked Questions

Why does industry risk level matter so much for my premium estimate?

Industry Risk Level sets the per-$1,000-of-revenue rate directly, and that rate spans more than a 7x range across the four tiers -- $2.50 for low-risk office or consulting work up to $18 for hazardous operations. It also determines which of two payroll rates applies (a higher rate kicks in at the "High" risk tier and above), so an inaccurate industry classification moves the estimate more than almost any other single input in this calculator.

Why didn't raising my deductible from $1,000 to $2,000 lower my premium?

The deductible discount in this calculator is a step function with two thresholds, not a smooth curve -- no discount applies below $2,500, a discount applies at $2,500 and up, and a larger discount applies at $5,000 and up. Moving from $1,000 to $2,000 stays entirely within the "no discount" tier, so the premium doesn't move at all; crossing $2,500 is what actually triggers a change.

How much does being in business longer actually save on premium?

This calculator applies experience discounts in four tiers: no discount under 3 years, a 4% discount at 3+ years, an 8% discount at 5+ years, and a 15% discount at 10+ years in business. The discount reflects that an established business with a track record is viewed as a more predictable, lower-risk insured than a brand-new one with no claims history to evaluate.

Does raising my coverage limit always increase the premium proportionally?

No -- the coverage limit factor in this calculator moves in three discrete steps rather than scaling continuously with the limit amount: a 0.85x factor below $1 million, a 1.0x baseline at $1-2 million, and a 1.3x factor at $2 million and above. Doubling your limit from $500,000 to $1,000,000 crosses one of those thresholds and raises the premium; doubling it again from $1,000,000 to $2,000,000 crosses the second threshold at exactly $2 million and raises it again -- but anything strictly between $1 million and $2 million sits flat at the 1.0x baseline with no further increase.
