Gravel Driveway Cost Guide: Materials and Depth
A gravel driveway is one of the most affordable surfaces you can install, but the cost hinges on depth, the number of layers, and delivered tonnage.
Gravel driveways are typically built in layers, each with a different stone size, over a total depth of 8 to 12 inches for a durable result. The material is sold by weight or volume, so the key is converting your driveway dimensions into cubic yards and then into tons.
The three-layer approach
A long-lasting gravel drive usually has three layers: a base of large stone (about 4 inches), a middle layer of smaller angular stone (about 4 inches), and a top layer of fine crushed gravel that locks together (about 2 to 4 inches). Skipping layers saves money now but leads to ruts and washouts later.
Estimating volume and tonnage
Volume equals length times width times depth in feet. A 40 by 12 foot driveway at 10 inches (0.83 ft) is 40 × 12 × 0.83 = about 398 cubic feet, or 14.7 cubic yards. Crushed gravel weighs roughly 1.4 tons per cubic yard, so that is about 21 tons of material across all layers.
2026 cost breakdown
| Item | Typical 2026 cost |
|---|---|
| Crushed gravel | $15 – $40 per ton |
| Delivery | $60 – $150 per load |
| Materials only (per sq ft) | $1 – $3 |
| Installed with grading | $3 – $8 per sq ft |
For the example driveway, material alone might run 400 to 800 dollars, with delivery and grading pushing a professional installation higher.
Depth and compaction
Order material for the loose depth you plan to spread, then compact each layer. Compaction reduces the depth by roughly 15 to 20 percent, so budget a little extra so the finished, compacted surface still reaches your target depth. A plate compactor or a few passes with a heavy vehicle helps the top layer lock in.
Don't forget edging and drainage
Without edging, gravel migrates into your lawn and thins out over time. Timber, steel, or paver edging keeps it contained. A slight crown or side slope sheds water so the base does not wash out during storms.
Ways to control cost
- Buy in full truckloads to lower the per-ton delivered price.
- Do the grading and spreading yourself if you can rent a compactor.
- Use local stone types, which are cheaper than trucked-in specialty gravel.
- Maintain the surface yearly with a light top-up to avoid a full rebuild.
