Gravel Driveway Calculator
Estimate loose aggregate volume for one driveway layer.
- Measured area
- 480 sq ft
- Before allowance
- 5.93 cu yd
- Bag alternative

- Material subtotal (entered price only)
- 0 USD
Whole packages round up. Prices include only the items you enter. Delivery, tax and installation may be extra.
How to calculate
Calculate each layer separately. This volume tool does not choose the base depth, grade or load capacity.
Worked example
Length (ft): 40 · Width (ft): 12 · Material depth (in): 4 · Bag yield (cu ft): 0.5 · Extra material (%): 10.
These inputs produce 6.52 cubic yards to order. Change the measurements above to match your project.
Before you order
Bulk suppliers may sell by ton. Obtain their actual tons per cubic yard; moisture and aggregate grading change weight.
For an irregular footprint, split the project into rectangles. Calculate each section and combine unrounded quantities before rounding the final order. Ask the supplier to confirm product yield and available package sizes.
Common questions
Is the allowance an installation recommendation?
No. It is an editable purchasing buffer. Cuts, spills and product requirements vary. Confirm the allowance for your layout.
Does this include installation costs?
Only prices you explicitly enter are included. A material-only result is not an installed quote. Request an itemized quote for site preparation, access, removal, drainage, labor, delivery and tax.
