Crushed stone calculator: tons, and how many trucks.
Type length, width and depth. Get tons and truckloads as you type.
Dense-graded base (crusher run) packs heavier, closer to 2,900–3,000 lb/yd³ compacted.
The crushed stone formula
tons = length (ft) × width (ft) × depth (in) ÷ 12 × 100 lb/ft³ ÷ 2,000
Worked example for a drainage bed, pipe bedding or a driveway: 80 ft × 12 ft at 6 in is 18.7 cubic yards and 25.2 tons with 5% extra, or 2 loads.
Crushed stone (#57, #2, base) is sold by the ton. Washed stone is lighter than dense-graded base; ask the quarry for its weight.
Crushed stone by the square foot
| Depth | 100 sq ft (10 × 10) | 1,000 sq ft |
|---|---|---|
| 2 in | 0.83 t | 8.3 t |
| 4 in | 1.67 t | 16.7 t |
| 6 in | 2.50 t | 25.0 t |
| 12 in | 5.00 t | 50.0 t |
No waste added in the table. Weight used: 2,700 lb per cubic yard. About 2,700 lb/yd³ (1.35 tons per cubic yard) for clean crushed stone like #57, a common quarry estimating figure.
Save it to a job. Dozer checks it against what's laid.
Saved estimates go on the site. Dozer adds up the haul tickets and the paver's tons each night and tells you if you're running over.
- Estimate vs. tons laid, every night
- Haul tickets read from a photo
- Overrun flagged before the next order
- Every estimate kept with the job

Questions crews ask
How do I calculate crushed stone tons?
Multiply length by width in feet, then by depth in inches divided by 12. That's cubic feet. Multiply by 100 lb per cubic foot and divide by 2,000 for tons. Add 5% for waste.
How much does a cubic yard of crushed stone weigh?
About 2,700 lb, or 1.35 tons. Dense-graded base (crusher run) packs heavier, closer to 2,900–3,000 lb/yd³ compacted.
How many tons for 80 by 12 ft at 6 in?
About 25.2 tons with 5% extra, or 2 truckloads at 15 tons a load.
How much crushed stone fits in a dump truck?
This calculator uses 15 tons a load. A tandem dump usually hauls 10 to 15 tons, a tri-axle 15 to 20 and a semi end-dump about 22 to 25; the legal weight on your roads decides.
