Landscaping Calculators
Mulch, sand, soil, gravel and cubic-yard calculators — work out how much bulk material to order by area and depth, in cubic yards, bags or tons.
CalcBooth’s landscaping calculators turn an area and a depth into the cubic yards, bags or tons of bulk material you actually order. The mulch calculator tells you how much mulch to spread a bed at the right depth and how many bags that is; the sand and soil calculators do the same for sand and topsoil, including the weight in tons for bulk delivery. The cubic yards calculator converts any length, width and depth into cubic yards and cubic feet — handy whenever a supplier quotes by the yard. Each tool shows the formula and lets you compare buying bags against bulk. Landscaping figures are planning estimates; settling, compaction and moisture change the real amount, so order a little extra and confirm with your supplier.
Which calculator do I need?
| Calculator | What it works out |
|---|---|
| Mulch Calculator | Find how much mulch you need — enter your bed area and depth to get the cubic yards, the number of 2 cu ft bags, and an estimated cost, with a coverage breakdown. |
| Sand Calculator | Calculate how much sand you need — enter your area and depth to get the volume in cubic yards and cubic feet, the weight in tons, and the number of 50 lb bags, with cost. |
| Soil Calculator | Find how much topsoil or dirt you need — enter your area and depth to get the cubic yards, the weight in tons, and the number of 40 lb bags, with a coverage and cost breakdown. |
| Cubic Yards Calculator | Convert any length, width and depth into cubic yards and cubic feet — enter your dimensions in feet or inches to size bulk material like concrete, gravel, mulch and soil. |
| Gravel Calculator | Calculate how much gravel or crushed stone you need — enter your area and depth to get the volume in cubic yards, the weight in tons, and the number of 50 lb bags, with cost. |
| Asphalt Calculator | Calculate how much asphalt you need — enter your driveway or lot size and thickness to get the tons of hot-mix asphalt, the cubic yards, and an estimated cost. |
| Paver Calculator | Calculate how many pavers you need for a patio, walkway or driveway — enter your area and paver size to get the paver count plus base gravel, bedding sand, polymeric sand and an estimated cost. |
| Polymeric Sand Calculator | Calculate how much polymeric sand you need for paver joints — enter your area, paver size and joint width to get the number of 50 lb bags, coverage per bag and cost. |
| Fence Calculator | Calculate fence materials — enter your fence length, post spacing and height to get the number of posts, rails, pickets and concrete bags, plus an estimated cost. |
| Sod Calculator | Calculate how much sod you need — enter your lawn length and width to get the square footage, number of rolls and pallets, and an estimated cost, with waste included. |
| Retaining Wall Calculator | Calculate retaining-wall materials — enter your wall length, height and block size to get the number of wall blocks, cap blocks and base gravel, plus an estimated cost. |
| Grass Seed Calculator | Work out how much grass seed you need - enter your lawn area, the grass type and whether you are seeding new or overseeding to get the pounds of seed and what a 50 lb bag covers. |
| Fill Dirt Calculator | Calculate how much fill dirt you need - enter the area and depth to get the cubic yards and the weight in tons, with a bulk cost estimate for grading, holes and low spots. |
| Pool Volume Calculator | Work out how many gallons your pool holds - enter the shape, size and depths to get the water volume in gallons, liters and cubic feet, plus what filling it costs at your water rate. |
| Driveway Cost Calculator | Estimate what a driveway costs to pave - enter the size and pick asphalt, concrete or gravel to get an installed price range, the cost per square foot and the tonnage of hot mix, with tear-out and grading priced separately. |
How these estimates are built
Every calculator in this category publishes the formula it runs, the constants it assumes, a worked example you can reproduce by hand, and the standard or manufacturer data sheet each constant comes from. Quantities include an adjustable waste allowance and round up to whole units, because you cannot buy part of a bag or box.
Cost figures are national US ranges and are material-only unless a calculator says "installed", so they exclude tax, permits and local labour rates. These are planning estimates, not quotes — read the full calculation methodology for what they cover, and the disclaimer for the structural and HVAC limits that apply.
