Landscape Material Calculators for DIY Projects

Calculate how much concrete, mulch, topsoil and more you'll need – in just a few clicks!

Welcome to IASCE – your one-stop resource for estimating landscape materials for home projects. Use our free calculators to plan exactly how much concrete, asphalt, gravel, topsoil, mulch, or rock you'll need. Simply choose a material below, input your project dimensions, and get instant results in cubic yards, tons, or bags. No more guesswork or over-buying – these tools help you save money and avoid waste on your DIY projects.

Concrete

Use our Concrete Volume Calculator and Concrete Cost Calculator to plan concrete for patios, sidewalks, or footings. Find out how many cubic yards (or how many premix bags) you'll need and estimate the cost of your concrete pour.

A 10×10 ft slab 4″ thick needs about 1.3 cubic yards, so our tools help ensure you order enough concrete without shortages.

Asphalt

Our Asphalt Volume Calculator and Asphalt Cost Calculator are perfect for driveway or paving projects. Enter your driveway's dimensions to estimate how much hot-mix asphalt you'll require and how much it might cost.

Most driveways use ~3 inches of asphalt over a gravel base – our calculator accounts for thickness to give you accurate volume in cubic yards and tons.

Gravel

Planning a base layer or gravel driveway? Use the Gravel Volume Calculator to determine the volume of gravel needed, and the Gravel Cost Calculator to budget for it. Ideal for projects like driveways, paths, or french drains.

Gravel can settle – our calculator even suggests adding about 10% extra to ensure full coverage.

Topsoil

Whether you're starting a lawn or filling a raised bed, our Topsoil Volume Calculator and Topsoil Cost Calculator will help. Input your garden's area to figure out how many cubic yards of rich soil you need and estimate the cost.

For healthy grass, plan on ~4–6 inches of topsoil – our tool helps convert that depth into volume so you know how much to order.

Mulch

Beautify your flowerbeds with the right amount of mulch. The Mulch Volume Calculator computes how many cubic yards or bags you need based on bed size and depth, and the Mulch Cost Calculator tallies the expense.

A 2–3 inch layer of mulch is ideal for weed suppression and moisture retention – our calculator ensures you buy just enough to achieve that depth.

Rock

For decorative stone or landscaping rock projects, use our Rock Volume Calculator and Rock Cost Calculator. These tools help you estimate quantities of river rock, gravel, or lava rock for features like dry creek beds or garden accents.

They'll convert your area and depth into cubic yards and tons, so you can confidently order rock – no second trips needed!

Each calculator page also includes helpful tips and examples to guide you. Whether you're pouring a new concrete slab, resurfacing a driveway, refreshing your garden beds, or creating a gravel path, IASCE's calculators make planning easy. Enjoy your outdoor DIY projects with the peace of mind that you have the right amount of materials!
