Reviewed by Engr. Talha Tariq | PEC License #: PEC-CIVIL-37815 | Last updated: 2025-10-25
Estimate how much gravel is required for your driveway. Use this free tool to calculate driveway gravel volume in cubic yards, weight in tons, and totally project cost including delivery fees. Easily figure out the necessary material for both base layers and soft top layers.
Estimate gravel required for a driveway based on length, width, and depth.
For driveways with multiple layers (e.g., base rock + top crushed stone), calculate each layer separately by using its specific depth.

Features of the Driveway Gravel Calculator
Calculates gravel needed for driveway base or top layers.
Shows results in the most commonly used purchasing units.
Estimates material budget for driveway gravel projects.
Helps account for settling, compaction, and extra coverage.
Easily include your supplier's delivery fee into your total estimate.
Choose between general gravel, pea gravel, crushed stone, or use custom density.
How to Use the Calculator
- Select the Unit for your measurements (feet, inches, meters).
- Enter the Driveway Length and Width.
- Input the Gravel Layer Depth based on which layer you are calculating (e.g., base layer vs top layer).
- Select the Gravel Type or input a Custom Density for weight estimation.
- Add a Waste Factor (10% is standard) to account for gravel compacting and settling into the soil.
- (Optional) Input the Material Price and a Delivery Fee for total cost estimation.
- Click Calculate.
Formulas
- Area = Length × Width
- Volume = Area × Depth
- Volume in Cubic Yards = Volume in Cubic Feet ÷ 27
- Weight = Volume (Cubic Feet) × Material Density (lb/ft³)
- Tons = Weight (lbs) ÷ 2000
- Material Cost = Estimated Tons × Price per Ton
- Total Cost = Material Cost + Delivery Fee
If you buy by the cubic yard, substitute Estimated Tons with Estimated Cubic Yards.
FAQs
How much gravel do I need for my driveway?
It depends on the length and width of your driveway, and the depth of the gravel layers. Simply measure your driveway's footprint and enter the desired depth into our calculator to get an accurate estimate in tons and cubic yards.
How deep should gravel be for a driveway?
A typical gravel driveway consists of two main layers: a base layer of larger crushed stone (about 4 to 6 inches deep) and a top layer of smaller surface gravel (about 2 to 3 inches deep). You should calculate the material for each layer separately.
How many tons of driveway gravel do I need?
Tonnage relies on the total volume in cubic feet and the density of your gravel. On average, a cubic yard of crushed stone driveway gravel weighs about 1.4 to 1.5 tons. Use our calculator to automate the math.
How much does driveway gravel cost?
Depending on your region and the type of crushed stone or gravel, costs typically range from $25 to $65 per ton or $35 to $75 per cubic yard. Expect to pay extra for delivery.
What is the best gravel depth for a driveway base?
A strong driveway base usually requires 4 to 6 inches of larger crushed stone (like #3 or #4 stone) to provide a stable, well-draining foundation for the smaller top surface layer.
