Smart Gravel Calculator

    Affiliate Disclosure

    Last updated: September 2026

    The short version

    Smart Gravel Calculator is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate I earn from qualifying purchases.

    What that means for you

    • Some links on this site — typically those marked "Shop on Amazon," "Pro pick," "Sponsored," or appearing in product grids and rails — are affiliate links.
    • If you click an affiliate link and buy a product, we may receive a small commission at no additional cost to you.
    • Commissions help keep our calculators free and ad-light.

    How we choose products

    We curate products that we believe genuinely match the calculator or guide you're using — wheelbarrows near the tonnage calculator, landscape fabric next to the driveway calculator, and so on. We don't accept payment from manufacturers to feature specific products. Our editorial recommendations are independent of the affiliate relationship.

    Where product details and prices come from

    Product titles, images, prices and availability are supplied by Amazon through its official Creators API and refreshed about every 12 hours. Every price is shown with the date and time it was retrieved. Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon.com at the time of purchase will apply to the purchase of the product. If our product data is more than 24 hours old, product cards are hidden until it is refreshed.

    Other relationships

    We may add other affiliate programs in the future (for example, lumber retailers or tool marketplaces). When we do, we'll update this page and continue to clearly mark sponsored and affiliate placements.

    FTC compliance

    This disclosure is provided in accordance with the U.S. Federal Trade Commission's 16 CFR § 255 "Guides Concerning the Use of Endorsements and Testimonials in Advertising." Every affiliate link on this site carries rel="sponsored nofollow noopener"and opens in a new tab.
