Affiliate Disclosure

Construct Math may participate in affiliate marketing programs. This means we may earn a commission when you click on certain links and make a purchase — at no additional cost to you.

FTC Disclosure

In accordance with the Federal Trade Commission's guidelines on endorsements and testimonials (16 CFR Part 255), we disclose that Construct Math may receive compensation when you purchase products through links on this site.

Affiliate Partners

Some links on this site point to retailers such as Home Depot and Lowe's. Where an affiliate relationship exists, we will earn a small commission on qualifying purchases. These links are selected for product relevance — the rebar calculator links to rebar products, the concrete calculator links to concrete mix — not for commission rate.

Our Editorial Independence

Affiliate relationships do not influence our calculator formulas, our content, or the accuracy of our estimates. We use the same CRSI, BIA, and NCMA standards regardless of which products are linked.

We do not accept payment for favorable placement in calculator results or editorial content. Product links are chosen for relevance, not commission rate.

How Affiliate Commissions Work

When you click an affiliate link and make a qualifying purchase within the retailer's attribution window (typically 1–30 days), we receive a small percentage of the sale price. The price you pay is the same whether or not you use our affiliate link.
