Calculator Terms and Disclaimer

These Calculator Terms and Disclaimer apply to all calculators, estimators, converters, formulas, material quantity tools, pricing tools, electrical tools, HVAC tools, construction tools, and related free resources made available through TradeToolz.com.

By accessing or using any calculator or tool on TradeToolz.com, you agree to these Calculator Terms and Disclaimer, our Terms of Service, and our Privacy Policy. If you do not agree, do not use the calculators or rely on any results.

Estimates Only; Not a Final Answer

TradeToolz.com calculators are provided for general informational, educational, planning, and estimating purposes only. Calculator results are estimates generated from formulas, assumptions, user-provided inputs, selected settings, and available reference values.

A calculator result is not a final project decision, professional determination, code-compliance determination, permit determination, safety determination, engineering decision, electrical design, construction plan, bid, quote, takeoff, purchase order, installation instruction, or substitute for professional judgment.

You are solely responsible for independently verifying all results before using them.

User Inputs Control the Result

Calculator results depend heavily on the accuracy and completeness of the information you enter, including measurements, units, waste factors, material densities, coverage rates, yields, voltage, amperage, phase, power factor, spacing, dimensions, packaging sizes, local requirements, manufacturer specifications, and project conditions.

TradeToolz.com is not responsible for inaccurate, incomplete, misunderstood, mis-entered, outdated, incompatible, or project-specific inputs. Even a mathematically correct result may be wrong for your project if the inputs, assumptions, conditions, code requirements, product specifications, or field conditions are different.

Independent Verification Required

Before relying on any result, you must verify it with the appropriate source for your project, which may include:

• A licensed contractor, electrician, plumber, HVAC professional, engineer, architect, inspector, or other qualified professional;
• Applicable building codes, electrical codes, plumbing codes, mechanical codes, fire codes, energy codes, zoning rules, permit requirements, and local amendments;
• The authority having jurisdiction;
• Manufacturer instructions, product data sheets, warranty requirements, installation manuals, packaging information, supplier information, and current pricing;
• Actual field measurements, site conditions, plans, specifications, drawings, and contract documents.

You agree not to treat any TradeToolz.com calculator result as the final answer unless you have independently verified that result for your specific project.

No Professional Advice

TradeToolz.com does not provide engineering, architecture, electrical contracting, plumbing, HVAC, construction, legal, tax, financial, safety, inspection, code-compliance, or other licensed professional services.

No calculator result creates a professional-client relationship, contractor-client relationship, engineer-client relationship, architect-client relationship, electrician-client relationship, inspector-client relationship, fiduciary relationship, warranty, guarantee, or duty to inspect, supervise, verify, or approve your project.

If your project involves safety, structural work, electrical work, plumbing, HVAC, permits, inspections, code compliance, regulated trades, hazardous conditions, public use, commercial work, or significant financial risk, you should obtain review from a qualified licensed professional before relying on any result.

Codes, Standards, and Local Requirements

Construction and trade requirements vary by jurisdiction, project type, occupancy, code cycle, local amendment, inspector interpretation, manufacturer requirement, utility requirement, and authority having jurisdiction.

TradeToolz.com calculators do not guarantee compliance with any code, standard, statute, regulation, permit requirement, inspection requirement, contract requirement, warranty requirement, or professional standard of care.

Any references to codes, tables, standards, industry practices, or formulas are for general estimating and educational use only and may not reflect the version, amendments, interpretations, or requirements applicable to your project.

Materials, Quantities, Waste, Pricing, and Availability

Material quantities, waste percentages, coverage rates, yields, densities, bag counts, bundle counts, board counts, roll counts, labor costs, permit costs, disposal costs, and pricing outputs are estimates only.

Actual project needs may vary due to cuts, defects, pattern layout, overage, breakage, compaction, moisture, slope, grade, site access, field conditions, crew methods, supplier packaging, local market pricing, taxes, fees, delivery charges, substitutions, and product availability.

You are responsible for confirming quantities, costs, and specifications before ordering materials, preparing bids, signing contracts, performing work, or making project decisions.

Electrical, HVAC, Plumbing, Structural, and Safety-Sensitive Work

Tools involving electrical loads, amps, voltage drop, wire size, HVAC sizing, ventilation, BTUs, water heaters, stairs, roofing, rebar, concrete, retaining walls, and similar safety-sensitive topics are especially limited.

These tools are not a substitute for licensed professional design, code review, load calculation, engineering analysis, permit review, field inspection, or manufacturer-approved installation instructions.

Do not rely on TradeToolz.com as the sole basis for work that could affect life safety, fire safety, electrical safety, structural safety, public safety, property damage, code compliance, or required licensure.

Assumption of Risk

You understand and agree that using calculator results involves risk. You voluntarily assume all risks associated with accessing, using, interpreting, verifying, or relying on TradeToolz.com calculators and outputs.

Limitation of Liability

To the maximum extent permitted by law, TradeToolz.com, its owners, operators, developers, affiliates, contributors, service providers, and licensors will not be liable for any direct, indirect, incidental, consequential, special, exemplary, punitive, or economic damages arising out of or related to your access to, use of, inability to use, interpretation of, or reliance on any calculator, formula, result, estimate, content, or website feature.

This limitation includes damages for lost profits, lost revenue, lost business, inaccurate bids, incorrect material orders, delays, rework, failed inspections, permit issues, code violations, property damage, personal injury, professional discipline, customer disputes, chargebacks, contract claims, negligence claims, or other losses, even if TradeToolz.com has been advised of the possibility of such damages.

Where liability cannot be fully excluded under applicable law, TradeToolz.com's total liability will be limited to the greater of: (a) the amount you paid to use the applicable calculator, if any; or (b) $100.

Some jurisdictions do not allow certain warranty disclaimers or liability limitations, so some of the above limitations may not apply to you. In those jurisdictions, liability is limited to the maximum extent permitted by law.

We make efforts to provide useful, transparent, and inspectable calculator logic, but we do not guarantee that any calculator, formula, reference value, result, interface, unit conversion, rounding method, table value, or output is error-free, complete, current, or suitable for your project.
