What is a Crushed Stone Calculator?

A crushed stone calculator estimates how much crushed stone you need for a driveway, patio, walkway, or drainage project — in tons, cubic yards, and weight — based on your area dimensions and depth. It also shows the total delivered cost two ways: by the ton and by the cubic yard, so you can choose the cheaper option.

This tool supports the sizes contractors and DIY homeowners actually buy: 3/4" crushed stone (the top search and most popular driveway size), #57 stone (clean 1" rock for drainage), #411 crusher run (dense-graded with fines for base layers), 1/2" chips for pavers, 3/8" pea-sized crushed for joint fill, #2 stone for heavy drainage, and recycled crushed concrete base for budget driveways.

How the Crushed Stone Calculator Works

Step 1 — Pick stone type: 3/4" is the default and most common for driveways. #57 for drainage. #411 crusher run for compacted base.
Step 2 — Pick area shape: Rectangle (most driveways/patios), circle (tree rings, fire pits), or triangle (irregular drainage beds).
Step 3 — Enter dimensions: Length and width in feet for rectangles, diameter for circles, base × height for triangles.
Step 4 — Enter depth: 2 in walkway, 4 in driveway top, 6+ in driveway base layer. Total driveway depth is usually 8–12 in across two layers.
Step 5 — Get your estimate: Tons, cubic yards, weight in lb, and delivered cost — priced both by the ton and by the yard, with the cheaper option highlighted.

Crushed Stone Volume Formula

Volume of crushed stone needed (in cubic feet):

Volume (ft³) = Area (ft²) × Depth (ft)

Where depth in feet = depth-in-inches ÷ 12. Then convert to the purchase unit:

  • Cubic yards (yd³) = ft³ ÷ 27
  • Weight (lb) = ft³ × 100 lb/ft³ (typical 3/4" crushed stone density)
  • Tons = weight (lb) ÷ 2000

Most US quarries sell crushed stone by the ton. Some landscape suppliers sell by the cubic yard. 1 yard of 3/4" crushed stone weighs about 2,700 lb ≈ 1.35 tons.

Real-World Example

Example: 20 ft × 10 ft Driveway, 4 inches Deep

Area = 20 × 10 = 200 ft². Depth = 4 in = 0.333 ft. Volume = 200 × 0.333 = 66.7 ft³.

With 10% waste factor: 73.4 ft³ = 2.72 cubic yards of crushed stone.

Weight at 100 lb/ft³ = 7,340 lb = 3.67 tons. At $38/ton for 3/4" crushed stone that is ~$139 delivered. If the yard sells by cubic yard at $52/yd³, the same project would cost $141 — essentially a tie, but deeper driveways almost always come out cheaper by the ton.

Crushed Stone Size Chart (What Every Number Means)

The number stamped on a crushed stone bag or quote refers to its sieve grade:

  • 3/8" (pea gravel size): Passes 3/8" sieve. Decorative paths, paver joints.
  • #57 / 1": 3/4"–1" washed rock, no fines. French drains, drainage.
  • 3/4" crushed stone: 3/8"–3/4" angular rock with some fines. Driveways, concrete base.
  • #411 / Crusher Run: 3/4"-minus blend with stone dust. Compacts into driveway base.
  • #2 / 2–3": Large chunks. Erosion control, heavy drainage, ditch fill.

How Much Does 3/4 Crushed Stone Cost Per Ton in 2025?

US 2025 averages for delivered 3/4" crushed stone run around $38/ton — with regional variance:

  • Midwest / Mid-Atlantic: $28–$40/ton
  • Northeast / New England: $42–$58/ton
  • South: $30–$42/ton
  • West Coast: $45–$60/ton
  • Rural areas far from quarry: Add $15–$50/ton delivery

Bulk orders above 10 tons often get a 10–15% per-ton discount. Always get three quotes — prices vary dramatically between local quarries and big-box landscape suppliers.

Crushed Stone Driveway: Base vs Top Layer

A durable gravel driveway uses two layers of different crushed stone:

  1. Base layer (4–6" of #411 crusher run): Dense-graded stone with fines that compacts into a hard, stable foundation. Drains water, supports weight.
  2. Top layer (2–4" of 3/4" crushed stone): Clean angular rock that locks together, sheds water, and looks attractive. Provides the "ride" surface.

Cheap one-layer driveways with only 3/4" crushed stone tend to wash out and rut within a few seasons. Always spend extra on the #411 base — it is the difference between a 5-year driveway and a 20-year driveway.

Who uses a crushed stone calculator?

1
DIY homeowners pouring gravel driveways, building French drains, and resurfacing walkways.
2
Landscape contractors quoting patio base, retaining-wall backfill, and drainage beds.
3
Paving contractors pricing #411 crusher run for sub-base under asphalt or pavers.
4
Farmers and property owners ordering crushed stone for barn pads, cattle lanes, and field drainage.
5
General contractors cross-checking aggregate quantities against sub quotes on site prep.

Crushed Stone Calculator FAQs

How do I calculate how much crushed stone I need?
Multiply the area (length × width in feet) by the depth in feet to get cubic feet. Divide by 27 to get cubic yards. Multiply cubic feet by 100 lb/ft³ (typical density of 3/4" crushed stone) and divide by 2000 to get tons. Always add 10% for waste. This calculator does all three steps automatically.
How many tons of 3/4 crushed stone do I need per cubic yard?
One cubic yard of 3/4" crushed stone weighs approximately 2,700 lb — that is about 1.35 tons. So if you need 3 cubic yards, you need roughly 4.05 tons. Density varies slightly by supplier (2,500–2,800 lb/yd³) but 1.35 tons/yd³ is the reliable rule of thumb.
How much does a ton of crushed stone cover?
One ton of 3/4" crushed stone covers about 120 ft² at 2" depth, 80 ft² at 3" depth, 60 ft² at 4" depth, or 40 ft² at 6" depth. For driveways, plan on 1 ton per 60 ft² at the typical 4-inch finished depth.
How much does a yard of crushed stone cost?
A cubic yard of 3/4" crushed stone costs roughly $45–$60 delivered in most US markets as of 2025. Priced by the ton, it runs $30–$55/ton depending on region, quarry distance, and bulk discounts. Crushed concrete base is the cheapest option at around $25–$35/ton.
What is the best crushed stone for a driveway?
For the top layer, use 3/4" crushed stone — it locks together well and gives a smooth ride. For the base layer, use #411 crusher run (dense-graded with fines) 4–6 inches thick because it compacts into a hard, stable sub-base. A full two-layer driveway is usually 4 inches of crusher run base topped with 2 inches of 3/4" clean stone.
How deep should crushed stone be for a driveway?
Plan on 8–12 inches total depth for a gravel driveway that will hold up under cars and light trucks: 4–6 inches of #411 crusher run base, then 2–4 inches of 3/4" crushed stone on top. Walkways need only 2–3 inches total. Heavy-vehicle driveways may need 12+ inches of base.
What is the difference between 3/4 crushed stone and #57 stone?
3/4" crushed stone contains fines (stone dust), which makes it compactable — good for driveways and under concrete. #57 stone is a clean, washed 1"-minus aggregate with no fines, so water passes through easily — it is the preferred choice for French drains, drainage fields, and footing drainage where compaction is not wanted.
Is it cheaper to buy crushed stone by the ton or the yard?
For projects over 1 cubic yard, by the ton is almost always cheaper in the US — that is how most quarries sell. Landscape yards often price by the yard at a markup. Below 1 cubic yard you may have a minimum delivery fee either way. This calculator shows you both totals side-by-side so you can compare instantly.
How much is a dump truck of crushed stone?
A standard tri-axle dump truck carries about 16–22 tons of crushed stone per load. At $38/ton for 3/4" crushed stone, a full load costs roughly $600–$840 plus a delivery fee of $75–$200 depending on distance. Call local quarries — many offer bulk discounts above 10 tons.
What is #411 stone vs #57?
#411 is dense-graded crusher run — a blend of stone plus fines that compacts into a hard surface, ideal for driveway base. #57 is a clean, washed 1"-minus single-size aggregate with no fines — great for drainage but will not compact. You usually want both: #411 for the base, #57 or 3/4" crushed stone for the top.
