How It Works

Our Gravel Calculator helps you accurately estimate the amount of gravel (in tons) required for your projects, from driveways to garden paths. Avoid over-ordering and unnecessary costs, especially with fluctuating material prices expected in 2026, where a ton of gravel averages $35-$50 depending on type and location. This tool ensures you have just enough for efficient project completion.

The calculation is based on volume, converting cubic feet to tons. We determine the area (length x width) and multiply by the desired depth to get the total cubic feet of gravel needed. This volume is then divided by the approximate density of gravel (typically 2,700 lbs per cubic yard, or 1.35 tons per cubic yard) to give you the total tons.

Always account for a 5-10% buffer for settling, compaction, and minor discrepancies in material delivery. A common mistake is underestimating depth, especially for high-traffic areas like driveways, which require at least 4-6 inches for stability. Remember, different gravel types have slightly varying densities.

Example: Gravel Driveway Project

  1. 1 Input: A driveway that is 50 feet long by 12 feet wide, with a desired gravel depth of 4 inches (0.33 feet).
  2. 2 Calculation: Area = 50 ft * 12 ft = 600 sq ft. Volume = 600 sq ft * 0.33 ft = 198 cubic feet. Since 1 cubic yard is 27 cubic feet, this is 198 / 27 = 7.33 cubic yards. At 1.35 tons per cubic yard, this equals 7.33 * 1.35 = 9.9 tons.
  3. 3 Result: You will need approximately 10 tons of gravel for your driveway project.
  4. 4 Context: Considering a 10% buffer, it would be wise to order around 11 tons. At an average 2026 price of $40 per ton, this project would cost approximately $440 for the gravel alone.

Frequently Asked Questions

How many tons of gravel do I need for my driveway?
A typical single-car driveway (10x50 feet at 4 inches deep) needs about 6-7 tons of gravel. Multiply length x width x depth (in feet), divide by 27 for cubic yards, then multiply by 1.4 for tons (gravel weighs about 2,800 lbs per cubic yard).
How much does a ton of gravel cost in 2026?
Gravel costs $15-75 per ton depending on type and location. Basic crushed stone runs $15-30 per ton, pea gravel $25-50, and decorative river rock $50-75. Delivery typically adds $50-150 per load.
What size gravel is best for a driveway?
Use a three-layer approach: 4-inch crushed stone (#3 or #4) as the base, 2-3 inches of #57 stone in the middle, and a 2-inch top layer of #411 or crusher run that compacts into a firm surface.
