Gravel Driveway Calculator

Calculate the gravel volume, weight and cost for a driveway.

Length

Width

Depth

Density (lb/ft³)

Price per ton ($)

Volume 11.111

Weight 15.75

Total cost ($) 0

Formula: tons = L × W × (depth/12) × density ÷ 2000

Step-by-step with your numbers:

1. Values used:

2. Length = 50

3. Width = 12

4. Depth = 6

5. Density = 105 lb/ft³

6. Price per ton = 0 $

8. Volume = 11.111

9. Weight = 15.75

10. Total cost = 0$

Plan a gravel driveway: how much gravel (volume, weight and cost) you need at your chosen depth.

The math behind it

Volume (ft³) = length × width × depth. Tons = volume × density ÷ 2,000. Loose gravel ≈ 105 lb/ft³.

For a long driveway, gravel is often laid in 2–3 layers of different stone sizes.

50×12 ft at 6 in → 300 ft³ = 11.1 yd³ ≈ 15.75 tons.

How deep should a gravel driveway be?

Total 4–6 in, ideally in layers (coarse base then finer top).
