Sixteen free calculators for soil, mulch, stone, sod, seed and the structures that organize a yard — quantities computed live from area, depth and geometry with the working shown, densities and coverage figures stated honestly and always editable. No baked-in prices, no brand specs: cost fields run on the rates you type in. Free, no signup, runs entirely in your browser.
Beds start with what fills them: the Soil Calculator for open ground, compost and topdressing, or the Raised Bed Soil Calculator for boxed beds — cubic feet, bags and a 60/30/10 mix, with hügelkultur fill to cut the order. The Plant Spacing Calculator counts what goes in, and the surface goes on last: mulch, pine straw by the bale, or river rock with honest per-product densities. The Fertilizer Calculator feeds the result.
New or thin lawns run through the Grass Seed Calculator (new-lawn and overseeding rates, plus a hydroseed cost check) or the Sod Calculator for instant grass in rolls, slabs and pallets — including realistic pallet weights. The boundary is the Hedge Spacing Calculator's job: plants per row from length and spacing, single or staggered double rows, with a 17-species spacing chart and trees-per-acre math.
Bulk stone and earth orders convert between volume and weight in the Cubic Yards to Tons Calculator, with the Gravel Calculator handling construction aggregates by area and depth. Standing water has two ends of the pipe: the Rainwater Harvesting Calculator for what a roof collects, and the French Drain Calculator for what has to leave — trench gravel with the pipe subtracted, slope as a real drop in inches, and dry well sizing. A garden pond gets volume, liner and pump from the Pond Calculator.
Jobs that touch the yard but live in other collections.
Hardscape runs through the Paver Calculator and the Retaining Wall Block Calculator in Concrete & Masonry, the Fence Post Concrete Calculator sets the posts, and the Roof Area Calculator supplies the footprint the rainwater calculator starts from.
Earth first, plants second, surfaces last. Size the soil or grade change (soil, raised bed, yards-to-tons tools), then count what goes in the ground (plant spacing, hedge spacing, sod or seed), then dress the surface (mulch, pine straw, river rock). Drainage is the exception — if water is part of the problem, the french drain comes before everything it protects.
Public physics and typical published ranges — and every one of them is editable in the tool, because real materials vary. Where the honest answer is a range (pine straw bales, sod pallets, stone densities), the tools show the range instead of hiding one number, and your supplier's figure always wins.
Because material prices vary too much by region and season for a baked-in number to be anything but wrong. Every cost field runs on the rate you type in — per bag, per yard, per bale, per pallet — so the totals reflect your suppliers, not a stale average.
No. The calculators run as JavaScript in your browser; your inputs never leave your device and there's no account or server involved. The share buttons just encode your inputs into the page's own URL.
