Affiliate Disclosure
Last updated: June 2026
How This Site Earns Revenue
levelcalc.com is free to use. We earn revenue through affiliate partnerships, contractor quote referrals, and display advertising. This revenue supports the ongoing maintenance and development of our calculators. You are never charged anything to use the site.
Affiliate Links
Some pages contain affiliate links. When you click an affiliate link and make a purchase or complete a qualifying action, we may earn a commission from the merchant at no additional cost to you. The price you pay is the same whether you use our link or go directly to the merchant's website.
Affiliate links typically appear as contextual recommendations near calculator results — for example, a link to buy the quantity of material a calculator estimates you need. We only surface products relevant to the calculator you are using.
Contractor Quote Requests
Some calculators offer the option to request quotes from local contractors or material suppliers (for example, for a concrete pour, roofing, or HVAC job). These requests are fulfilled through third-party lead-referral networks. If you choose to submit a quote request, the contact and project details you provide are shared with those networks and matched contractors so they can contact you with quotes. We may receive a referral fee for qualifying leads.
Submitting a quote request is always optional and is never required to use any calculator. By submitting a request, you consent to be contacted by matched providers, which may include calls, texts, or emails. See our Privacy Policy for how this information is shared.
Our Affiliate & Referral Partners
We may earn commissions or referral fees from the following types of partners:
- Building material & tool retailers — home improvement stores and online marketplaces (concrete, lumber, drywall, fasteners, tools, etc.)
- Tool & equipment brands — manufacturers and dealers of construction tools and equipment
- Contractor & home-service networks — lead-referral services that connect you with local pros (concrete, roofing, HVAC, solar, remodeling)
- Material suppliers — ready-mix concrete, aggregate, and bulk material delivery services
- Estimating & contractor software — project management and estimating tools for trade professionals
Specific partners and programs may change over time. Many calculators have no affiliated products or quote options at all.
How These Relationships Affect Our Content
Affiliate and referral partnerships do not influence our calculations, formulas, or educational content. Our calculators reference published industry standards (IRC, NEC, CRSI, BIA) and manufacturer specifications, and produce results based solely on the inputs you provide. We do not alter calculator outputs, material quantities, or recommendations to favor a partner. Recommendations appear separately from results and are clearly identified.
Display Advertising
This website may display advertisements from third-party ad networks (such as Google AdSense). These ads are served by the network, not by us, and we do not control which specific ads appear. The presence of an advertisement is not an endorsement.
Your Choices
You are never required to click an affiliate link, request a quote, or interact with an advertisement. Every calculator and all educational content remain fully accessible without doing so. You can always navigate directly to any merchant by searching for them in your browser.
FTC Compliance
This disclosure is provided in accordance with the Federal Trade Commission's guidelines on endorsements and testimonials (16 CFR Part 255). We are committed to transparency about our revenue sources.
