Gravel Cost Guide
Gravel Cost Calculator
Estimate gravel cost using project dimensions, gravel depth, cubic yards, tons, waste allowance, price per ton, delivery, and basic project factors.
How a gravel cost calculator works
A gravel cost calculator starts with project size and gravel depth. It converts the area into volume, converts volume into cubic yards and tons, then estimates cost using price per ton or price per cubic yard.
Volume
Length × Width × Depth = Cubic Feet
Cubic yards
Cubic Feet ÷ 27
Estimated tons
Cubic Yards × Tons Per Cubic Yard
Material cost
Estimated Tons × Price Per Ton

Example gravel cost estimate
For a 20 foot by 20 foot area with 4 inches of gravel, the volume is about 133.33 cubic feet. That equals about 4.94 cubic yards. If the gravel weighs 1.4 tons per cubic yard, the project needs about 6.91 tons before waste. With 10% waste, the estimate becomes about 7.6 tons.

What affects gravel cost?
Gravel cost depends on more than square footage. Depth, gravel type, compaction, delivery distance, local supply, and preparation work all affect the final estimate.
- • Project length and width
- • Gravel depth
- • Gravel type and size
- • Tons per cubic yard
- • Waste allowance
- • Delivery distance
- • Site preparation or grading
Common gravel cost uses
Gravel cost estimating tips
Measure in feet
Use consistent units for length, width, and depth before converting to cubic yards.
Convert depth correctly
Four inches is 0.333 feet. Six inches is 0.5 feet. Depth errors can change the estimate quickly.
Add waste
Include a small waste allowance for uneven ground, spreading loss, and compaction.
Check material density
Different gravel types can have different tons-per-yard values.
Separate delivery
Delivery may be priced separately from the material cost.
Use related calculators
Use the driveway calculator for driveway-specific estimates and the cost-per-ton guide for pricing.

Gravel cost calculator FAQ
How do I calculate gravel cost?
Measure the project length, width, and gravel depth. Convert the volume to cubic yards, estimate tons, multiply by price per ton, then add waste, delivery, labor, and site preparation costs.
What information do I need for a gravel cost estimate?
You need project dimensions, gravel depth, tons per cubic yard, waste percentage, price per ton or cubic yard, and any delivery or labor costs.
Should I estimate gravel by ton or cubic yard?
Use both. Project size is usually calculated in cubic yards, but gravel is often sold by the ton.
Should I include waste in gravel cost?
Yes. A 5% to 10% waste allowance helps account for uneven ground, compaction, spreading loss, and small measurement differences.
