Aggregate Calculator
Find the volume and weight of crushed concrete, crusher run, decomposed granite, #57 stone, limestone, or asphalt from length, width, depth, and waste.
Optional buffer for spillage and compaction.
Default is a typical density for the selected material; adjust from a supplier spec sheet if known.
Result
1.02 cu yd
10 ft x 10 ft at 0.25 ft deep needs about 1.02 cubic yards (1.38 tons) of crushed concrete
Quick Answer
An aggregate calculator multiplies length, width, and depth, adds waste, then applies the density of the chosen material. For a 10 by 10 foot area, 0.25 feet deep, crushed concrete at 100 lb/cu ft with 10 percent waste, the result is 27.5 cubic feet, about 1.02 cubic yards, 2,750 pounds, or 1.375 US short tons.
What An Aggregate Quantity Calculator Measures For Base Layers
An aggregate calculator finds volume and weight for a flat bed or base layer of crushed material. It multiplies length by width by depth, adds the set waste rate, and converts cubic feet to cubic yards. The tool then multiplies the volume by the bulk weight per cubic foot for the selected material to show pounds and US short tons, which helps compare a volume quote with a load sold by weight before ordering. This single tool covers crushed concrete calculator, crusher run calculator, decomposed granite calculator, #57 stone calculator, limestone calculator, and pavement or asphalt base calculator searches, since they all share the same length × width × depth × density method and differ only in typical density. Compaction, moisture, particle shape, base thickness, and supplier rules can change the final amount, so use the exact product weight and confirm the order with the supplier.
How Aggregate Weight And Volume Are Fully Calculated
The three sizes form the base volume. Waste raises that volume. The selected material sets a default density, which turns volume into weight. Cubic yards equal cubic feet divided by 27.
- Base volume = length × width × depth.
- Volume with waste = base volume × (1 + waste percentage ÷ 100).
- Weight in pounds = volume with waste × density for the selected material.
- US short tons = weight in pounds ÷ 2,000.
Using This Crushed Stone Calculator In Five Clear Steps
Inputs
- Material: crushed concrete, crusher run, decomposed granite, #57 stone, limestone, or asphalt.
- Length: the base or bed length in feet.
- Width: the base or bed width in feet.
- Depth: the planned layer in feet.
- Density: the material weight in lb/cu ft, set from the material choice and editable.
- Waste: an optional added percent.
Steps
- Choose the aggregate material.
- Measure length and width.
- Convert depth in inches to feet.
- Keep the default density or enter a supplier value.
- Enter a waste rate or use zero.
- Read cubic feet, cubic yards, pounds, and tons.
Aggregate Example With Each Step And Rounding Shown
10 ft length, 10 ft width, 0.25 ft depth, crushed concrete at 100 lb/cu ft density, and 10 percent waste.
- Base volume: 10 ft × 10 ft × 0.25 ft = 25 cu ft.
- Waste factor: 1 + 10 ÷ 100 = 1.10.
- Final volume: 25 cu ft × 1.10 = 27.5 cu ft.
- Cubic yards: 27.5 cu ft ÷ 27 = 1.018518... cu yd.
- Pounds: 27.5 cu ft × 100 lb/cu ft = 2,750 lb.
- Tons: 2,750 lb ÷ 2,000 = 1.375 tons.
27.5 cubic feet, 1.02 cubic yards, 2,750 pounds, or 1.38 US short tons. Cubic yards and tons round to two decimal places after full-precision math.
When An Aggregate Estimate Fits A Base Or Fill Project Plan
Use the estimate for driveways, paths, patio bases, and drainage fill with known sizes. Ask the supplier or project lead to confirm material type, density, compaction rate, depth, and the final order.

Assumptions
- The base or bed has even depth.
- Density matches the chosen material.
- Waste applies to the full base volume.
- One cubic yard equals 27 cubic feet.
- One US short ton equals 2,000 pounds.
Limitations
- Odd shapes need separate sections.
- Compaction changes loose versus placed volume.
- Moisture and particle shape can change bulk density.
- The tool does not check base, drainage, or load design.
- Local plans and site rules still apply.
In Practice
A common mistake is using one density figure for every aggregate type. Crusher run, decomposed granite, #57 stone, limestone, and asphalt all pack to different bulk weights. Pick the material first, confirm the density against the supplier spec sheet, then adjust the number if it differs. The result is an estimate and does not replace plans, local codes, or expert review.

Frequently Asked Questions About Aggregate Estimates
Does One Calculator Cover Crusher Run, Limestone, And #57 Stone?
Yes, crusher run, decomposed granite, #57 stone, limestone, and asphalt base all use the same volume formula. Only the default density differs by material, and that value can be edited to match a supplier spec sheet.
How Do Cubic Yards Convert To Tons For Aggregate?
Cubic yards need a bulk weight value before they can become tons. Multiply yards by 27 to get cubic feet, multiply by pounds per cubic foot for the material, and divide by 2,000 to get US short tons.
Should A Waste Rate Be Added For Aggregate Base?
A waste rate can cover compaction loss and spillage during spreading. The calculator lets you set any rate instead of using a fixed value. Enter zero when the supplier or plan already includes a buffer.
Why Do Aggregate Materials Weigh Differently At The Same Volume?
Aggregate materials weigh differently because their bulk densities differ by particle size, shape, and moisture. Crusher run packs tighter than open stone like #57. Use the supplier's product weight instead of treating all aggregate as equal.
