Disclaimer

Our gravel calculator provides estimates based on standard formulas and average material densities. The actual amount of gravel you need may vary significantly from our estimates due to a variety of factors, including:

• Compaction: Gravel settles and compacts over time, which may require additional material to maintain your desired depth.
• Waste and Spillage: Material is often lost during delivery, unloading, and spreading. We recommend adding 5–10% extra to account for waste.
• Irregular Shapes: Our calculator assumes regular geometric shapes. Irregular areas may require manual adjustment of your estimates.
• Ground Preparation: If your site requires excavation, grading, or ground preparation, additional material may be needed to account for settling.
• Material Variations: Actual gravel density can vary by material type, source quarry, and moisture content, affecting the weight per cubic yard.
• Measurement Accuracy: Errors in measuring your project area dimensions will directly affect the accuracy of the estimate.
• Edging and Borders: If your project includes edging or borders, additional material may be needed beyond the calculated area.
• Existing Material: If you are adding gravel on top of existing material, the depth calculations may differ from a fresh installation.

We strongly recommend ordering 10–15% more gravel than the calculator estimate to account for these variables and avoid running short mid-project.

The weight conversions used in our calculator (typically 1.4 to 1.7 tons per cubic yard depending on gravel type) are averages based on common gravel varieties. Actual weights will vary depending on:

• The specific type of gravel or crushed stone
• Moisture content at the time of delivery
• Particle size and gradation of the material
• Source quarry and geological composition

Coverage estimates assume a consistent, level application of gravel to a flat surface. Sloped terrain, uneven ground, or areas with significant grade change may require more material than calculated. Always confirm weight and coverage estimates with your local gravel supplier, who can provide material-specific data sheets for the exact product you are purchasing.

Any cost estimates provided by our calculator are based on typical regional average prices and are provided for general budgeting purposes only. Actual costs will vary significantly based on your location and will not include many additional charges that are common in gravel purchases, including:

• Delivery Fees: Costs for transporting gravel to your site, which vary by distance and supplier.
• Fuel Surcharges: Variable fuel-related charges added by delivery services.
• Minimum Order Requirements: Many suppliers have minimum order quantities or delivery minimums.
• Spreading and Installation Costs: Labor costs for spreading, leveling, or compacting the gravel.
• Equipment Rental: Costs for renting a skid steer, compactor, or other equipment needed for installation.
• Landscaping Fabric: Weed barrier fabric installed beneath the gravel, if applicable.
• Edging Materials: Borders or edging to contain the gravel.
• Excavation Costs: Removing existing soil or material before installation.
• Taxes and Surcharges: Sales tax, environmental fees, and other applicable charges.

We recommend obtaining quotes from at least three local gravel suppliers before making any purchasing decision. Prices change frequently and our estimates may not reflect current market rates in your area.
