Landscaping Calculator: Mulch

Landscaping Calculator turns your measurements into the exact material order you need. Mulch, topsoil, gravel, sand, pavers, sod, concrete and more, in cubic yards, cubic feet, cubic meters, tons, tonnes, bags and dollars.

Built for landscape contractors, lawn care crews, gardeners and homeowners who are tired of estimates that are half a load off.

WHY THIS ONE IS DIFFERENT

Every material carries a real density value, and you can edit it. Pick pea gravel, number 57 stone, crusher run, decomposed granite, river rock, lava rock, screened topsoil, hardwood mulch or your own custom material, then adjust the density to match what your supplier actually delivers. No vague size ranges, no hidden assumptions.

Tap Show formula on any result and see every step: the area, the depth conversion, the density used, the waste factor and the final number. If an estimate looks wrong, you can see exactly why.
