Contractor Insurance Cost: What You'll Pay in 2026

How much contractor insurance costs — and why one number doesn't fit

Contractor insurance can cost as little as $83.33 per month for a qualifying general contractor buying general liability only in Texas. That figure is a minimum premium from one carrier for one coverage line. Most contractors need more than GL alone.

The real cost depends on how many coverage lines you buy, what trade you work in, your payroll, your state, and what your contracts require. Progressive says contractor insurance ranges from several hundred to thousands of dollars per year depending on work performed and coverages selected.

Here is what general contractors actually pay at the median, based on marketplace applicant data:

These figures come from carrier filings and marketplace data for general contractors. Your actual cost depends on your trade, state, payroll, and coverage package. A solo handyman buying GL only pays far less than a general contractor with 10 employees, three trucks, and a $5M umbrella requirement.

The rest of this page breaks down what each coverage line costs, which business details change the price, and how to compare quotes from carriers that insure your kind of work.

What each coverage line costs separately

Contractors rarely buy one policy. A typical program includes general liability, workers compensation, commercial auto, tools and equipment coverage, and sometimes umbrella or builder's risk. Each line is priced independently using different rating factors.

The table below shows median monthly costs for general contractors who applied through a national insurance marketplace. These are medians, not minimums or maximums. Your quote will differ based on your specific business details.

General liability

GL covers third-party bodily injury, third-party property damage, and personal and advertising injury claims. The median cost is $142/month for general contractors. Thimble reports a range of $796 to $1,230 per year for general contractor GL. GL premiums are based on revenue, work type, claims history, and whether you use uninsured subcontractors.

Workers compensation

Workers comp is the most expensive line for most contractors with employees. The median is $318/month. Thimble reports an annual average of $3,264 for contractor workers comp. The formula is: job classification rate multiplied by experience modification factor multiplied by payroll divided by 100. Adding employees changes the total insurance package sharply, even if GL itself stays flat.

Commercial auto

Commercial auto runs $180/month at the median. The cost depends on number of vehicles, vehicle type, driver records, travel radius, and whether you have permanently attached equipment like ladder racks or tool boxes. Most personal auto policies exclude or limit coverage for vehicles used regularly in a business. If you use a truck or van for contractor work, you likely need a commercial auto policy to avoid a coverage gap.

Tools and equipment (inland marine)

Tools and equipment coverage is the cheapest line at $14/month median. It covers tools, equipment, and materials in transit or at job sites. Thimble gives a broader range of $250 to $1,000 per year depending on total tool and equipment values.

Commercial umbrella

Umbrella coverage adds limits above GL, auto, and employer's liability. The median is $143/month. Many contractors buy umbrella only because a contract requires it. Public works contracts can require $5M to $25M in umbrella limits depending on project size.

Which business details carriers use to price your policy

Carriers ask about these details when they price a contractor account. Each one can raise or lower your premium.

How the rating basis works for contractor GL

Filed contractor GL manual text shows that some subcontracted work is rated on total cost of work rather than revenue or payroll. This means the carrier measures your exposure by the total dollar value of subcontracted work, not just your own payroll. If you subcontract heavily, your GL premium reflects that total project cost.

How contract requirements add to your premium

Many contractors are surprised when a GC contract pushes their premium higher. The contract may require endorsements and limits you did not budget for.

Additional insured endorsements

An additional insured endorsement extends your policy's protection to the GC or project owner. CG 20 10 covers ongoing operations only. CG 20 37 adds completed operations coverage after the job is done. Construction contracts commonly require both.

Primary and noncontributory wording

Primary and noncontributory means your policy pays first and does not seek contribution from the GC's policy when both are triggered by the same loss. This shifts more financial responsibility to your carrier, which is why it adds cost.

Waiver of subrogation

A waiver of subrogation means your insurer gives up the right to recover from a liable third party after paying your claim. GCs require this so they cannot be sued by your carrier after a loss. It removes a recovery option for the insurer, so it adds premium.

Umbrella limits driven by project size

Public works contracts can require umbrella limits far above standard GL. Caltrans requires $5M umbrella for bids up to $1M, $10M for bids up to $10M, and $25M for bids over $25M. Private commercial GCs often require $2M to $5M umbrella. Each increase in umbrella limits adds to your annual premium.

Why a painter and a roofer don't pay the same premium

The BLS counts nearly 588,440 specialty trade contractor establishments across dozens of class codes. Each class code reflects a different injury frequency, claim severity, and loss pattern. That is why a painter and a roofer are not priced the same.

How class codes group trades by risk

Carriers assign each contractor a class code based on the work performed. Interior painting, residential electrical, commercial roofing, and excavation each have separate codes with separate rates. The code determines the base rate per $100 of payroll for workers comp and influences GL pricing.

Low-hazard vs high-hazard examples

A solo interior painter with no employees may pay $800 to $1,500 per year for GL. A roofer with a crew pays multiples of that because roofing class codes carry higher rates due to fall exposure, completed operations claims, and weather damage. Filed rating manuals distinguish industrial building subcontracted work as a severe class compared to lower-hazard interior trades.

Subcontractor exposure and residential construction pressure

Small and mid-sized residential construction contractors face pressure from rising defect claims, social inflation, and risk-transfer gaps. Carriers scrutinize subcontractor controls, certificates, additional insured status, and written contracts. Weak subcontractor management raises premiums or limits carrier options.

Six ways to lower your contractor insurance cost

You can influence what you pay. These tactics lower premiums without cutting the coverage your contracts require.

Premium audits and how claims history affects renewal pricing

Your quoted premium is not always your final premium. Carriers audit the exposure base after the policy year, and claims change what you pay at renewal.

What a premium audit is

At the end of the policy year, the carrier compares your estimated payroll, revenue, or total cost of work against actual figures. If actual exposure was higher than estimated, you owe additional premium. If it was lower, you may get a return premium.

Filed contractor GL rating text separates premises/operations, products, and completed operations sublines for contractor classifications. Each subline can be audited independently, so underreporting in any category triggers an adjustment.

Payroll underreporting example

This is an extreme case outside the construction industry, but the principle applies to every contractor. If you estimate low and your actual payroll or revenue comes in higher, the audit bill arrives after the policy year. Report accurately from the start.

How claims affect renewal pricing

Prior claims raise future premiums. For workers comp, claims affect your experience modification rating, which multiplies the base rate. For GL, carriers review loss history and may increase rates, add exclusions, or decline to renew.

Carriers are pulling back on limits and maintaining a firm stance on exclusions in the construction market. Local market conditions, class of business, and exposure mix continue to affect which carriers will quote and at what price. A clean loss history gives you more options at renewal.
