How Does the Gravel Calculator Work?

This gravel calculator estimates how many tons and cubic yards of gravel you need for driveways, paths, drainage, and landscaping projects. It uses a standard gravel density of approximately 105 lbs per cubic foot.

Steps:

  1. Enter your area length and width in feet.
  2. Enter the desired depth in inches — 4 inches for driveways, 2 inches for decorative paths.
  3. Get instant results — tons, cubic yards, cubic feet, and estimated cost.
💡 Pro Tip

For driveways, use 4 inches of compacted gravel base. For decorative paths and landscaping, 2–3 inches is sufficient. Always add 10% extra to your order for compaction and waste.

💰 Bulk Savings Tip

For any project over 1 ton, buy gravel in bulk directly from a landscape supply yard or quarry. Bulk pricing is typically 40–60% cheaper per ton than buying bags. For large driveway projects, ask about full truckload pricing — often 15–25% cheaper than per-ton pricing.

Example Calculation

You want to gravel a 60 ft × 12 ft driveway with 4 inches of crushed stone.

Area:

60 ft × 12 ft = 720 sq ft

Volume (cu ft):

720 × (4÷12) = 720 × 0.333 = 240 cu ft

Cubic yards:

240 ÷ 27 = 8.9 cubic yards

Tons needed:

240 × 0.054 = ~13 tons

Cost ($45/ton):

13 × $45 = ~$585 plus delivery

Buying & Ordering Tips

  • Order early — call your supplier 1–2 days ahead for bulk delivery, especially during spring and summer when demand is high.
  • Confirm truck size — standard dump trucks hold 10–14 cubic yards. Always confirm the exact capacity before ordering.
  • Add waste factor — always order 10–15% more than your calculated amount to account for uneven ground, settling, and waste.
  • Compare 3 suppliers — prices for bulk materials vary significantly between suppliers. Always get at least 3 quotes for large orders.
  • Check delivery access — confirm the delivery truck can access your property before ordering. Some sites may require a smaller truck at higher cost per yard.

Frequently Asked Questions

How much gravel do I need for a driveway?+
A standard single-car gravel driveway (120 ft × 10 ft) at 4 inches deep needs approximately 15 tons or 11 cubic yards of gravel. A double-car driveway (120 ft × 20 ft) needs about 30 tons. Always add 10% for compaction and waste.
How many tons of gravel are in a cubic yard?+
One cubic yard of gravel weighs approximately 2,800 lbs (1.4 tons) for standard crushed stone. This varies by gravel type — pea gravel is lighter at about 2,700 lbs/cu yd. Use the formula: cubic yards × 1.4 = tons (approximate for crushed stone).
How much does gravel cost?+
Bulk gravel costs $28–$100 per ton depending on type. Crushed stone runs $38–$55/ton. Pea gravel costs $35–$55/ton. Delivery typically adds $50–$200 depending on distance and quantity. Full truckload delivery (14–16 tons) is often the most cost-effective option.
What type of gravel is best for a driveway?+
Crusher run (compacted crushed stone) or #57 crushed stone are the best options for driveways. Crusher run compacts well and creates a stable surface. Pea gravel and river rock are too smooth and round — they shift and migrate, making poor driveway materials.
How accurate is this gravel calculator?+
Very accurate for rectangular areas. It uses a standard gravel density of 105 lbs/cu ft. Always order 10% extra for compaction and waste. Confirm pricing with your local supplier — gravel prices vary significantly by region and type.
