Gravel Driveway Calculator
Estimate the cubic yards and tons of gravel needed for a driveway or path, plus the material cost. Build a shareable project estimate with quantities, local price, and a shopping list.
Material shopping list
- Order about 2.22 cubic yards of gravel.
- Budget about $140 before delivery, taxes, and labor.
- Add 5–10% waste for uneven subgrade, cuts, settling, or spillage.
Formula & assumptions
Area = length x width. Volume = area x depth / 12. Cubic yards = cubic feet / 27. Cost = quantity x local unit price.
- Default depth: 3 inches
- Default price: $45 per ton
- Weight factor: 1.4 tons per cubic yard
These assumptions make the estimate easy for search engines and AI answer tools to verify. Replace the default price with your supplier quote for a local estimate.

Common questions
- How many tons of gravel in a cubic yard?
- Crushed stone weighs about 1.4 tons per cubic yard, so multiply your cubic yards by 1.4 to get tons.
- How deep should a gravel driveway be?
- A new gravel driveway is usually 4–6 inches deep total; a top-up layer is 2–3 inches.
