Landscaping & Outdoor Calculators
Calculate mulch, gravel, soil, sand, and paver quantities for landscaping and outdoor projects. Free material calculators for homeowners.
Gravel Calculator
Calculate gravel in tons and cubic yards for driveways, paths, and drainage. Pick a stone type and depth for tonnage, cost, and a base-layer compaction factor.
Use Calculator
Mulch Calculator
Calculate how much mulch you need in cubic yards or bags, then compare bulk vs bagged cost. Enter bed size and depth for coverage and delivery estimates.
Use Calculator
Paver Calculator
Calculate pavers plus base gravel, bedding sand, polymeric sand, and edging for a patio or walkway. Full materials list with pattern cut-waste and cost.
Use Calculator
Pool Calculator
Calculate your pool's volume in gallons for any shape, then get the exact chemical doses — shock, pH, alkalinity, stabilizer — and the cost to heat the water.
Use Calculator
Sand Calculator
Calculate sand for paver bedding, sandboxes, fill, and concrete bases. Get cubic yards, tons, and 50-lb bag counts, plus a bags-vs-bulk price comparison.
Use Calculator
Soil Calculator
Calculate how much soil you need in cubic yards, bags, and tons — topsoil, garden soil, or fill dirt for beds, lawns, and raised beds with a settling factor.
Use CalculatorOrdering the Right Amount of Material
Bulk landscape materials like mulch, gravel, and topsoil are sold by the cubic yard. Getting the quantity right on the first order saves money and avoids extra delivery fees, which can run $50-$100 per trip. One cubic yard covers about 162 square feet at 2 inches deep or 108 square feet at 3 inches deep. For larger projects these numbers add up fast. A 20x30 foot patio base needing 4 inches of gravel requires about 7.4 cubic yards, which weighs roughly 11 tons.
Bulk delivery is almost always cheaper per yard than buying bagged material from a home improvement store. A cubic yard of bulk mulch typically costs $25-$50 delivered, while the same volume in bags could cost $100 or more. Bagged materials make sense for small areas under 50 square feet or when you need precise control over placement. If you need to measure an irregularly shaped bed first, our area and volume calculators can help you get an accurate square footage before ordering.
Always round up your material estimate by 5-10% to account for settling, spillage, and uneven ground. Compacted gravel loses about 15% of its volume compared to loose fill, so factor that into driveway and walkway projects. If your outdoor project also involves building a retaining wall, pergola, or deck frame, check our construction and framing calculators for lumber and structural material estimates.
