# How Much Do Contractor Bonding and Insurance Cost?

Contractor bonding and insurance cost depends on trade, payroll, state and claims history more than on company size. One industry dataset puts small construction firms at an average of about $89 a month for general liability and $175 for workers' comp, while contract bond premiums typically run 0.5% to 3% of the contract price.

## Key takeaways

- Budget for at least four lines: license bond, general liability, workers' comp (if you have employees) and commercial auto.
- Workers' comp is the big variable: payroll ÷ 100 × class rate × experience mod, and roofing class rates dwarf clerical ones.
- License bonds are cheap relative to the bond amount; contract bonds cost a percentage of each job.
- Insurance is overhead. Price it into every job through your overhead rate or labor burden, not as an afterthought.
- Clean books, a safety program and verified sub certificates are the three levers you control.

## What insurance and bonds does a contractor actually need?

Most trades businesses need a license bond, general liability and, once they hire, workers' comp and commercial auto. What's required by law varies by state; what's required by customers comes from the contract. The table below lists each line, who requires it and what drives the price.

**The main lines and what drives each premium**

| Coverage or bond | Who typically requires it | What drives the cost |
| --- | --- | --- |
| License (contractor) bond | State licensing boards; e.g. $25,000 in California, $30,000 for a Washington general contractor | Bond amount, owner credit, claims history; paid yearly as a small percentage of the bond amount |
| [General liability](https://www.brix.so/learn/general-liability-insurance) | Some state boards (Washington, Oregon), most customers and permits | Trade, payroll or revenue, limits, location, claims, uninsured subs |
| [Workers' compensation](https://www.brix.so/learn/workers-compensation) | State law, from the first employee in many states | Payroll by class code, state rates, experience mod |
| Commercial auto | State law for business vehicles; customers | Number and type of vehicles, radius, driver records |
| Tools and equipment (inland marine) | Usually optional | Value of tools and equipment, theft history |
| Umbrella | Larger commercial contracts | Underlying limits and total exposure |
| Contract bonds (bid, performance, payment) | Public owners; federal jobs over $150,000 under the Miller Act | Contract amount, your financials and track record |

## Sourced benchmarks: what small contractors pay

Most published "average cost" numbers are unsourced. Two we can attribute: Insureon's customer data for construction businesses (page updated July 21, 2026, drawn from its own small-business policyholders) and Nevada's state risk management guide on surety premiums.

**Attributed cost benchmarks (not quotes)**

| Line | Benchmark | Source and basis |
| --- | --- | --- |
| General liability | Average $89 per month, $1,069 per year | Insureon, construction businesses on its platform |
| Business owner's policy (GL + property) | Average $125 per month, $1,503 per year | Insureon |
| Workers' compensation | Average $175 per month, $2,101 per year | Insureon |
| Commercial auto | Average $268 per month, $3,212 per year | Insureon |
| Tools and equipment | Average $42 per month, $505 per year | Insureon |
| Commercial umbrella | Average $93 per month, about $1,111 per year | Insureon |
| Surety bonds (mostly license bonds) | Average $9 per month, about $112 per year | Insureon |
| Contract bonds (performance and payment) | About 0.5% to 3% of the contract amount; usually no separate charge for a bid bond | Nevada State Risk Management, 10 Things You Should Know About Surety Bonds |

_Insureon's averages skew toward very small firms, many with one or two workers, and cover all construction trades together. Your premium can be several times these figures._

## A worked example: insuring a four-truck HVAC company

> **Example (illustrative numbers, not quotes)**
>
> An HVAC company runs four trucks with five field techs, one office manager and the owner. Field payroll is $300,000; office payroll is $50,000. Revenue is $1.4 million.
>
> **Workers' comp.** Say the HVAC class rate is $4.50 per $100 and clerical is $0.30 (illustrative). Field: $300,000 ÷ 100 × $4.50 = $13,500. Office: $50,000 ÷ 100 × $0.30 = $150. With a 1.00 mod, about **$13,650**.
>
> **General liability** at $1 million / $2 million, rated on revenue and payroll: say **$6,500**.
>
> **Commercial auto** for four trucks: say **$9,000**. **Tools and equipment** on $60,000 of gear: say **$900**. **License bond** on a $25,000 bond: say **$250**.
>
> Total: about **$30,300 a year**, or roughly 2.2% of revenue. Spread over about 8,000 billable field hours, that's **$3.79 per hour** that has to be in the rate before the shop makes a dollar.
>
> If two lost-time claims push the mod to 1.30, workers' comp alone rises to $17,745, adding $4,095 a year to overhead.

**Insurance cost per billable hour**

```
Insurance per hour = Total annual premiums ÷ Annual billable hours
```

Where:
- Total annual premiums = all bonds and policies, including audit adjustments
- Annual billable hours = hours you actually invoice, not hours paid

Put that number into your [overhead rate](https://www.brix.so/learn/overhead) or [labor burden](https://www.brix.so/learn/labor-burden) so every quote carries it. The [overhead rate calculator](https://www.brix.so/tools/overhead-rate-calculator) and [labor burden calculator](https://www.brix.so/tools/labor-burden-calculator) do the math.

## What makes bonding and insurance cost more, or less?

- **Trade.** Roofing, electrical and steel are rated far above cleaning or landscaping maintenance. Some insurers won't write roofers at all.
- **Payroll and revenue.** Most policies are rated on exposure and audited at year end; growth means a bill after the audit.
- **Experience mod.** Claims raise your mod for three years. A safety plan and return-to-work program lower it.
- **Limits and deductibles.** $1 million / $2 million costs more than state minimums; a higher deductible lowers premium but raises what you pay on small claims.
- **Subcontractors without certificates.** Uninsured subs are charged to your policy at audit. Collect a [certificate of insurance](https://www.brix.so/learn/certificate-of-insurance) from each one.
- **Credit and financials.** Bond pricing leans on the owner's credit and, for contract bonds, on financial statements and the [WIP report](https://www.brix.so/learn/wip-report).
- **State.** Class rates, benefit levels and litigation climate all vary. Texas lets most employers opt out of workers' comp; California requires it from the first employee.

## Bonding and insurance cost by trade

**Relative cost pressure by trade (qualitative)**

| Trade | Workers' comp | General liability | Notes |
| --- | --- | --- | --- |
| Roofing | Highest | High | Falls from height; some states require comp for roofers with no employees |
| Electrical | Moderate | Moderate to high | Fire claims drive completed-operations pricing |
| HVAC | Moderate | Moderate | Attic and rooftop work; refrigerant exclusions |
| Plumbing | Moderate | Moderate | Water damage is the common GL claim |
| Landscaping and tree work | Low to very high | Low to moderate | Mowing is cheap; tree removal is not |
| Cleaning | Low | Low | Payroll-heavy, so comp still adds up |
| General contractor | Varies with self-performed work | High | Pays for uninsured subs at audit |

_Direction only. Actual class rates are filed by state and set by insurers._

## Is it cheaper to go without?

Usually not, once you count what it costs to be caught. A single uncovered water-damage claim can exceed a decade of general liability premiums, states fine and stop-work employers without required workers' comp, and licensing boards suspend licenses when bonds or insurance lapse. Unlicensed contractors in Florida can't even enforce their contracts. See [contractor license](https://www.brix.so/learn/contractor-license) and [surety bond](https://www.brix.so/learn/surety-bond).

## How to lower the bill

1. **Classify payroll correctly.** Office staff in a field class is wasted premium.
2. **Run a safety program and report claims fast.** Both move the experience mod.
3. **Collect certificates from every sub before they start.**
4. **Shop at renewal.** Get two or three quotes, including a state fund if your state has one.
5. **Keep clean, job-level books.** Sureties and underwriters price uncertainty; good financials shrink it.
6. **Raise deductibles only to what you can pay from cash.**

## Frequently asked questions

### How much does it cost to get bonded and insured as a contractor?

For a small shop, a license bond typically costs a small percentage of the bond amount per year, general liability averaged $89 a month and workers' comp $175 a month in Insureon's construction customer data, and commercial auto averaged $268 a month. A multi-truck crew in a high-risk trade can pay many times those averages.

### What percentage of revenue should insurance be for a contractor?

There's no published standard, and it varies widely by trade. The useful method is to total your actual premiums, including audit adjustments, divide by billable hours, and build that figure into your rates through your overhead or labor burden calculation.

### How much does a $1 million general liability policy cost for a contractor?

It depends on trade, payroll or revenue, state and claims history. Insureon reports an average of $1,069 a year across construction businesses on its platform, most of them very small. A roofer or electrician with a crew should expect substantially more. Get several quotes.

### How much does a performance bond cost?

Nevada's state risk management guide puts contract surety premiums at about 0.5% to 3% of the contract amount, depending on project size, type, duration and the contractor. On a $400,000 job at 1.5%, that's $6,000, which contractors normally include in the bid.

### Why did my workers' comp bill go up after the audit?

Premium is based on estimated payroll at the start of the policy and trued up to actual payroll at audit. If you hired, paid overtime, or used subcontractors without certificates of insurance, the auditor adds that exposure and bills the difference.

### Can I pass insurance costs on to customers?

Yes, and you should, by including them in your overhead rate so every quote carries its share. Public bids also commonly include bond premiums as a line item. What you can't do is make employees pay for workers' comp; states generally prohibit deducting it from wages.
