How is builders risk insurance priced?

Most builders risk policies are priced as a rate per $100 of the total completed value of the project. The insurer multiplies that rate by the completed value to produce the premium. The rate is usually a small fraction of a percent, so the premium tends to land at a fraction of a percent of total project cost.

What is a typical builders risk rate?

As a broad guide, rates commonly fall somewhere in the range of roughly $0.10 to $1.00 or more per $100 of completed value, which is about 0.1% to 1%+ of the project cost. Frame residential and light commercial jobs sit at the lower end; high-hazard, ground-up, or catastrophe-exposed projects sit higher. Your actual rate depends on construction type, location, term, and deductible.

Does the deductible affect the premium?

Yes. A higher deductible lowers the premium because you retain more of each loss. Wind, hail, and named-storm deductibles are often a percentage of value rather than a flat dollar figure, which can be significant on coastal or high-value projects.

Is builders risk paid upfront or monthly?

One-time project policies are usually written for the full construction term and the premium is fully earned, often paid at binding. Contractors who build continuously can instead use a reporting or blanket program that bills based on values as jobs start, which spreads the cost.

How Much Does Builders Risk Insurance Cost? (Rate per $100 of Value)

By Tamir Lerner · Builders Risk Insurance Pros · Updated July 22, 2026

Quick answer: Builders risk insurance is usually priced as a rate per $100 of the project's total completed value. That rate is a small fraction of a percent, so the premium typically works out to somewhere around 0.1% to 1%+ of total construction cost. A straightforward $500,000 build might run a few hundred to a couple thousand dollars for the term; hazard, location, term length, and deductible move it from there.

The first question almost every owner and contractor asks is, "What is this going to cost me?" The honest answer is that builders risk pricing is formulaic once you understand the inputs, but the range is wide because projects vary so much. Below is how the math actually works and the levers that push your number up or down.

How builders risk is priced: rate per $100 of value

Builders risk is almost always rated on the total completed value of the project — the full cost to build, including materials and labor, but usually excluding the land and, in many cases, excluding existing structures in a renovation. The insurer applies a rate per $100 of value. The formula is simple:

(Total completed value ÷ 100) × rate = premium

So if a project has a completed value of $600,000 and the rate is $0.30 per $100, the premium is (600,000 ÷ 100) × $0.30 = $1,800 for the construction term. Change the rate to $0.60 and the premium doubles to $3,600. That single rate figure is where all the underwriting judgment lives.

Typical builders risk rate ranges

There is no universal price sheet, but rates commonly fall within a broad band. Use these as directional estimates, not quotes:

Project profile	Typical rate per $100	As % of value
New frame residential / light commercial, low-hazard area	~$0.10 – $0.35	~0.1% – 0.35%
Standard ground-up commercial, average exposure	~$0.25 – $0.60	~0.25% – 0.6%
Renovation / remodel of an existing occupied structure	~$0.40 – $1.00+	~0.4% – 1%+
Catastrophe-exposed (coastal wind, wildfire, seismic) or high-hazard	$0.75 – well above $1.00	0.75% – 2%+

Ranges are illustrative and vary by carrier, year, and market conditions. A hard insurance market pushes rates up across the board; a soft market pulls them down. Only a quote reflects your real number.

What drives your builders risk premium

1. Construction type

Fire resistance is the single biggest factor. A concrete or steel (non-combustible) building rates far lower than combustible frame construction, because frame is more vulnerable to fire during the vulnerable period before finishes and fire protection are in place. This mirrors the same construction-classification logic used across commercial property, described in IRMI's builders risk overview.

2. Project value and scope

Higher completed value means more exposure and a higher premium in raw dollars, even if the rate itself holds steady. Renovations often rate higher than ground-up work because you are also exposed to the existing structure, occupants, and the unknowns of an older building.

3. Location and catastrophe exposure

Coastal wind and named-storm zones, wildfire-prone regions, and seismic areas carry higher rates and often percentage-based catastrophe deductibles. Crime and vandalism rates in the immediate area also matter, since theft of materials is a common builders risk claim.

4. Term length

Builders risk is written for the construction period, commonly 6, 12, or 18 months. Longer terms cost more, and extending a policy after the fact usually carries an additional premium. Under-estimating the schedule is a frequent and avoidable cost.

5. Deductible

Choosing a higher deductible lowers the premium because you retain more of each loss. Watch for separate wind/hail and named-storm deductibles, which are frequently a percentage of value rather than a flat dollar amount — on a large or coastal project, that can be a meaningful out-of-pocket figure.

6. Add-ons and endorsements

Extensions like soft costs, delay in completion, flood, earthquake, and ordinance or law add premium because they add coverage. They are often well worth it, but they do move the total. ISO's commercial property program (via Verisk/ISO) is the framework many of these endorsements build on.

A quick worked example

Say you are building a single-family spec home with a completed value of $500,000, wood frame, in a low-hazard suburban area, on a 12-month term with a standard deductible. A plausible rate might land around $0.20 per $100:

(500,000 ÷ 100) × $0.20 = $1,000 for the full construction term.

Move that same home to a wildfire-exposed hillside and add soft costs coverage, and the rate could climb to $0.50 or more, pushing the premium to $2,500+. Same house, very different number — which is exactly why a specialist quote beats a rule of thumb.

How to lower your builders risk cost

Insure the right value — the completed value, not inflated. Over-insuring wastes premium.
Set a realistic term so you are not paying to extend later.
Secure the site — fencing, lighting, and locked storage reduce theft claims and support better renewals.
Consider a higher deductible if your cash flow can absorb small losses.
Bundle thoughtfully — contractors who build continuously often save with a blanket or reporting-form program instead of one-off policies.

The bottom line

Builders risk cost comes down to one figure — the rate per $100 of completed value — driven mainly by how the project is built, where it sits, how long it takes, and what you add on. For most standard projects the premium lands at a fraction of a percent of total cost, which is modest insurance against a fire, storm, or theft that could otherwise stop the job cold. The right move is to insure the accurate completed value, set a realistic term, and let a specialist shop the rate.
