Construction project coverage and premium planner
Builders Risk Insurance Cost Calculator
Estimate a completed project value and term premium, then compare quoted limits for the project, soft costs, property in transit and temporary off-site storage.
Last Updated: August 28, 2026
This calculator uses your construction budget and insurer quote inputs. It does not assign a national rate. Builders risk pricing depends on the project, construction type, location, schedule, protections, catastrophe exposure, limits, deductible and insurer.
Calculate Builders Risk Coverage and Term Cost
Enter values expected at project completion, excluding land. Then enter the rate, limits, charges and taxes shown by the insurer or broker.
Coverage Target and Limit Comparison
A positive gap means the entered limit is below the calculated exposure target.

What This Builders Risk Insurance Calculator Estimates
The calculator builds a completed project value from construction labor and materials, existing property exposed during renovation, owner-furnished items, contractor profit and overhead, general conditions, temporary works, debris-removal allowance and contingency.
It compares that target with the quoted project limit. It also checks soft costs, materials in transit and off-site storage as separate exposures because policies often apply separate sublimits and conditions.
The premium section accepts either a quoted term rate per $100 of project limit or a quoted base term premium. It adds entered coverage charges, subtracts a discount, applies a minimum premium and then adds the entered tax-and-fee percentage. It does not predict underwriting rates.
How to Use the Builders Risk Cost Calculator
- Enter the anticipated labor and material cost for permanent project work. Exclude land.
- For renovation, enter the value of the existing structure exposed to loss. Confirm whether the builders risk policy or an existing property policy covers it.
- Add owner-furnished materials, contractor profit, overhead, general conditions, temporary works and debris-removal exposure only when not included elsewhere.
- Enter a project-value contingency. The calculator rounds the direct project target up to the next $1,000.
- Estimate soft costs, the highest transit value and the highest value at one off-site storage location.
- Copy every quoted limit and sublimit from the proposal.
- Select the rate or direct-premium method. Enter the quoted term, charges, discount, minimum premium, taxes, fees and deductible.
- Review coverage gaps and the premium breakdown with the owner, contractor, lender, broker and contract documents.
Builders Risk Cost Formulas
The term rate applies to the full quoted policy term. Dividing the term premium by policy months creates a monthly comparison figure only. It does not state what an insurer will charge for an extension, cancellation or early completion.
Worked Builders Risk Insurance Example
Assume a renovation has $500,000 of construction labor and materials, $100,000 of existing structure exposure, $25,000 of owner-furnished equipment, $50,000 of profit and general conditions, and $20,000 of temporary works and debris-removal exposure.
The example also produces a $5,000 soft-cost gap, $10,000 transit gap and $10,000 off-site storage gap. These limits protect different exposures and should not be combined into one net amount.
What Builders Risk Insurance Covers
Builders risk is first-party property insurance for a building or structure during construction, renovation or repair. Depending on the form, it can cover permanent work, building materials, supplies, labor value, temporary structures and property of others for which an insured is responsible.
Travelers states that a builders risk policy generally covers repair or replacement of materials at a covered structure after causes such as fire, wind, theft, collapse, lightning, hail, explosion or vandalism. The Hartford notes that coverage can include materials at the site, in transit or temporarily stored off-site, plus temporary structures and debris removal.
Coverage is not uniform. A policy can use named perils or broader covered-risk wording, but exclusions and conditions remain. The actual form, endorsements, location schedule and contract requirements control.
How to Set the Project Property Limit
The limit should reflect the insured value exposed at project completion, not the current amount spent and not the land value. The Hartford advises that builders risk limits should equal anticipated construction project costs. Insurers can require a completed-value basis, reporting form or another valuation method.
Permanent work
Include labor, materials and installed equipment that become part of the completed project.
Project costs
Review contractor profit, overhead, general conditions and owner-furnished property for inclusion.
Cost changes
Update the insurer when scope, contract value, material prices or completion date changes.
Underinsurance can create a claim shortfall or coinsurance problem. Overstating the value can increase premium without increasing what the policy owes beyond the actual covered loss. Ask the insurer how audits and final project values affect premium.
Hard Costs, General Conditions and Soft Costs
Hard Costs
Hard costs are physical construction expenses. They include materials, installed equipment and labor needed to build or repair covered project property. Contractor profit and overhead can form part of the insured repair value when included in the contract and policy valuation.
General Conditions
General conditions support project execution. Examples include project supervision, temporary offices, fencing, security, temporary utilities, scaffolding, equipment rental, permits, cleanup and site services. IRMI notes that these costs form part of values submitted to builders risk underwriters, although claim treatment depends on whether a cost relates directly to repairing insured damage or to delay.
Soft Costs
Soft costs are added expenses caused by a delay following insured physical damage. Examples include additional interest, real estate taxes, insurance, permits, architectural or engineering fees, legal fees and marketing expenses. Soft-cost coverage normally needs a stated endorsement, sublimit, waiting period and period of indemnity.
Delay in Completion and Business Income
Direct property coverage repairs damaged work. It does not automatically pay every financial consequence of delay. Delay-in-completion coverage can include defined soft costs, lost rental income, gross earnings or other time-element losses after insured physical damage.
Zurich lists delay-in-completion protection for gross earnings, rental income and soft costs as available builders risk coverage. These exposures require separate values and careful naming of insured parties. A contractor's delay costs and an owner's lost rent are different interests.
This calculator tests the soft-cost sublimit only. It does not estimate lost rental income, business income, waiting periods, delay duration, financing schedules or indemnity periods.
Transit, Off-Site Storage and Temporary Structures
Materials can accumulate before installation. A single shipment or storage location can hold more value than a standard sublimit. Coverage can depend on distance, approved locations, security, packing, carriers, reporting and whether the property is specifically intended for the project.
Enter the highest value expected in one shipment and at one off-site location. Compare each exposure with its own sublimit. Do not assume the full project limit applies outside the jobsite.
Temporary structures can include scaffolding, fencing, forms, falsework, site offices and temporary utilities. Confirm whether they are covered property, a coverage extension or contractor's equipment insured elsewhere.
Renovation and Existing Structure Exposure
A renovation creates two property interests: existing construction and new work. The builders risk form can cover both, only the new work or neither existing property without an endorsement. The owner's permanent property policy can also contain renovation coverage, creating possible gaps or overlapping insurance.
Enter existing structure value only when the proposed builders risk policy is intended to insure it. Confirm valuation, protective safeguards, occupancy, phasing, water damage, hot work and whether operations continue during construction.
Structural alterations, demolition, foundation work and projects already underway can need special underwriting. Arrange coverage before work begins.
Deductibles, Catastrophe Limits and Testing
The deductible is the amount assigned to the insured after a covered loss. Different deductibles can apply to water damage, wind, named storms, flood, earthquake, theft, testing or other causes. Percentage deductibles can create a much larger retained amount than the primary dollar deductible entered here.
Flood, earthquake and high-hazard wind coverage can be excluded, limited or separately priced. Verify the project address, flood zone, distance to coast, wildfire exposure and protection plan. Do not assume all-risk wording removes exclusions.
Testing and commissioning can damage mechanical, electrical or process equipment. Hot testing, cold testing, boilers, pressure systems and machinery breakdown can require specific coverage and time limits.
Policy Term, Completion and Extensions
Builders risk is normally written for a project term. The Hartford states that coverage can end at project completion, occupancy, opening for intended use or policy expiration. Policies can also end after acceptance, abandonment or another stated event.
Construction delays do not automatically extend insurance. Request an extension before expiration and provide the updated schedule, percentage complete, remaining work and loss information. An insurer can charge additional premium, change terms or decline an extension.
Do not use the calculator's monthly equivalent as an extension price. Builders risk premiums can be fully earned, minimum earned or subject to short-rate and audit rules.
Named Insureds and Contract Requirements
The owner, general contractor, subcontractors, lender and other parties can have financial interests in the project. Construction and loan agreements usually assign responsibility for buying the policy, setting limits, naming parties, paying deductibles and providing waivers of subrogation.
IRMI explains that the first named insured can receive cancellation notices, make policy changes, receive return premiums and carry deductible responsibility. Being listed as an additional insured does not guarantee every party receives soft-cost or delay coverage.
Match the policy to the signed contract. Resolve conflicting insurance requirements before work starts.
Builders Risk Is Not General Liability
Builders risk covers direct physical loss or damage to insured project property. General liability covers covered claims that the contractor or another insured caused bodily injury or damage to someone else's property. Both can be needed.
- Workers compensation covers employee work injuries under applicable law.
- Commercial general liability addresses third-party injury and property-damage claims.
- Contractor's equipment insurance covers mobile tools and equipment not becoming part of the project.
- Professional liability addresses covered design or professional-service claims.
- Pollution liability addresses defined pollution conditions.
- Installation floaters cover defined contractor installation exposures when not adequately covered under builders risk.
Factors That Affect Builders Risk Insurance Cost
The Hartford states that cost varies by project scope, materials, location, term and coverage details. Underwriters also review construction type, protection class, catastrophe exposure, site security, water controls, hot-work procedures, contractor experience, loss history, occupancy, project schedule and requested extensions.
Optional flood, earthquake, wind, testing, soft costs, delay, transit and off-site storage coverage can increase premium. Higher limits and lower deductibles generally cost more, but pricing is not a single public formula.
Use the same project values, limits, deductible, coverage form and endorsements when comparing quotes. A lower term premium can reflect narrower coverage.

Builders Risk Insurance Cost Calculator FAQs
What is builders risk insurance?
Builders risk is first-party property insurance for insured buildings, structures, materials and related property during construction, renovation or repair. Coverage depends on the policy form, project, locations, limits and endorsements.
How much does builders risk insurance cost?
There is no single standard price. Insurers consider project value, location, construction type, schedule, catastrophe exposure, contractor experience, protections, limits, deductible and optional coverage. Use a real quoted rate or base premium in the calculator.
What value should the builders risk limit use?
The project limit generally needs to reflect anticipated completed construction cost, including insured labor, materials and other values required by the policy and contracts. Exclude land and avoid duplicating costs already in the contract sum.
Is land value included in builders risk coverage?
No. Land is not construction property and should not be included in the builders risk project limit or the calculator's project-value inputs.
Does builders risk cover an existing structure during renovation?
Only when the policy or endorsement includes the existing structure. Some policies cover new work but not existing property. Coordinate the builders risk form with the owner's permanent property insurance.
What are soft costs in builders risk insurance?
Soft costs are defined extra expenses caused by delay after insured physical damage, such as additional interest, design fees, permits, taxes and insurance. They normally require an endorsement, sublimit and supporting schedule.
Are materials covered in transit or off-site storage?
Coverage is available under many builders risk forms, but separate limits, locations, distances, reporting, security and carrier conditions can apply. Compare the highest value at risk with each quoted sublimit.
Does builders risk include flood and earthquake coverage?
Not automatically. Flood, earthquake and high-hazard wind can be excluded, sublimited or separately priced. Confirm the covered causes of loss, catastrophe limits and deductibles for the project address.
When does a builders risk policy end?
Coverage can end at completion, occupancy, acceptance, opening for intended use, abandonment or policy expiration, depending on the form. A construction delay does not automatically extend the policy.
Is builders risk the same as general liability insurance?
No. Builders risk covers insured project property against covered physical loss. General liability addresses covered third-party bodily injury and property-damage claims. A construction project often needs both.
Methodology, Sources and Editorial Review
The calculator adds five direct project-value categories, applies the selected contingency and rounds up to the next $1,000. It checks four coverage targets independently. The premium calculation uses either the entered rate or base premium, then applies charges, discount, minimum premium and taxes in the stated order. Calculations run in the browser and do not request an address, company name, contract, insurer login or policy number.
