LandscapeCalculator.net is a free set of calculators for working out the materials, quantities and rough costs of landscaping projects. You enter your measurements and get cubic yards, tons, bags, pallets or a cost range. You don't need an account, and nothing you type is sent to us.
The site is operated by iBizWorks. We built it because the most common landscaping mistakes are math mistakes: ordering two yards of mulch when the beds needed four, or getting a tree quote with no idea whether it was fair. Each calculator answers one of those questions before you spend money.
What the Site Covers
Every page answers a version of one question: how much? How much material, how many bags or pallets, how deep, or what a job is likely to cost. The current tools cover:
- Bulk materials: mulch, topsoil, gravel and stone, landscape rock, sand, fill dirt and compost
- Lawns: sod, grass seed and fertilizer
- Hardscape: pavers, concrete edging and retaining walls
- Irrigation: sprinkler system cost
- Trees: tree trimming cost and tree removal cost
The blog explains the reasoning behind the numbers: how deep mulch should be, how topsoil differs from fill dirt, what drives retaining wall prices, and similar questions.
How Our Calculators Work
The material calculators use the same arithmetic a landscape supplier uses at the counter:
- Volume: length × width × depth. Depth is converted from inches to feet, and the result is divided by 27 to get cubic yards, the unit most bulk materials are sold in.
- Weight: stone and soil are often sold by the ton. We convert cubic yards to tons using typical densities for each material, for example about 1.35 tons per cubic yard for topsoil and about 1.45 for decorative rock. The gravel calculator lets you pick the material type because densities vary widely.
- Bags and pallets: bagged products are converted from cubic feet using common bag sizes (2 and 3 cu ft for mulch). Sod is converted using a standard pallet coverage of 450 sq ft.
- Waste and settling: where it matters, results include or recommend an allowance, typically 5–15% depending on the material, for compaction, cuts and spillage.
The cost calculators (tree trimming, tree removal and irrigation) work differently. They start from typical U.S. price ranges for the job size you choose, adjust for factors like access, condition and number of zones, and return a low-to-high range rather than a single figure. Real quotes depend on your region, season, contractor and site conditions.
The Limits of Any Online Estimate
A calculator is only as good as the measurements you give it. Irregular beds, slopes, soft ground and local material differences all change the real number. Treat our results as a planning estimate. Before you order, confirm the quantity and density with your supplier. For structural work such as taller retaining walls, or for anything involving digging near utilities, consult a qualified professional. In the U.S., always call 811 before you dig.
Keeping the Numbers Honest
We review the formulas and price ranges periodically and correct them when we find a better source or a mistake. Articles link to outside references, such as university extension services, when a topic deserves more depth than a calculator page can give.
If you spot a result that looks wrong, or a calculator you wish existed, please tell us. Corrections from homeowners and contractors are the most useful feedback we get.
