Construction & Landscaping Calculators
Estimate volume, weight, bags, and cost before you buy. Each calculator runs in your browser — no signup, no paid APIs. Results are supplier-ready: cubic yards, US tons, retail bag counts, and optional cost estimates with compaction allowance.
Pick the tool that matches your material — gravel, pea gravel, or mulch — and get supplier-ready numbers in seconds.
Construction & base materials
Driveways, drainage, paver bases, concrete pours, and structural fill. These calculators estimate cubic yards, tons, and cost before you order from a quarry or supplier.
-
Material Calculator
Calculate yards, tons, weight, bags and cost for gravel, road base, crushed stone, pea gravel or mulch.
Open calculator -
Gravel Calculator
Estimate gravel coverage, cubic yards, tons, and cost for driveways, paths, drainage areas, and landscape projects.
Open calculator -
Road Base Calculator
Estimate dense graded road base in cubic yards and tons for driveways, shed pads, and compacted aggregate layers.
Open calculator -
Crushed Stone Calculator
Plan crushed stone quantities for compacted bases, drainage layers, driveways, and hardscape projects.
Open calculator -
Paver Base Calculator
Estimate base gravel, bedding sand, and material depth for patios, walkways, and paver installations.
Open calculator -

Landscaping & garden materials
Garden beds, tree rings, decorative paths, and weed-barrier projects. Get cubic yards, bag counts, and coverage estimates you can take straight to the nursery or landscape yard.
Which calculator should I use?
Gravel vs pea gravel
Use the gravel calculator for driveways, drainage trenches, and compactable base stone. Use the pea gravel calculator for decorative walkways, patios, and rounded stone beds.
Mulch depth and bags
The mulch calculator supports rectangle, circle, and triangle beds with 2–4 inch depth presets. Output includes cubic yards and 2 or 3 cu ft bag counts for retail shopping.
Supplier-ready output
Every calculator shows a recommended order with compaction and waste allowance, plus tons and bag counts where relevant. Copy or share the estimate when you request a delivered quote.
Check the assumptions before you order
Gravel density and weight
Compare typical pounds and US tons per cubic yard in the gravel density chart.
Cubic yards vs tons
Use the yards-versus-tons guide to compare quarry and landscape-yard quotes on the same basis.
Road and driveway base
Start with the road base calculator, then compare the result with the driveway gravel calculator.
From site measurements to supplier quantities
Most material-ordering mistakes begin with units. Project dimensions are usually measured in feet and inches, while suppliers quote cubic yards, tons, or bags. These calculators keep the conversion in one place: enter the shape and installed depth, choose the material, and review both volume and weight before requesting a quote. Rectangle, circle, triangle, and known-area modes make it easier to handle beds, paths, driveways, and irregular layouts without building a separate spreadsheet.
The raw mathematical volume is rarely the final order. Uneven ground, spreading loss, settlement, and compaction can all increase the amount required. Use the allowance controls to model those conditions, then round to a unit your supplier actually sells. For gravel and base materials, confirm the density or tons-per-yard conversion on the quote. For mulch, compare the stated bag volume and coverage because particle size and moisture affect how a delivered yard settles.
Cost estimates are most useful when every quote uses the same basis. Compare yard prices with yard prices and ton prices with ton prices, or use the calculator to convert between them. Ask about minimum orders, delivery zones, fuel charges, taxes, pallet deposits, and placement fees before choosing the lowest headline number. The shared estimate gives you a concise quantity and assumptions list to send to a quarry, nursery, landscape yard, or contractor for confirmation.
