When considering large landscaping or gardening projects, soil is typically purchased in bulk, measured by the cubic yard. A cubic yard is a significant volume of material, measuring three feet long, three feet wide, and three feet deep. The base price for a single cubic yard of basic, screened topsoil generally falls within a range of $20 to $60. This material cost is only a starting point, as the final expenditure is heavily influenced by the quality, specific type of soil, and necessary logistical fees.
Factors Influencing the Base Price of Soil
The inherent composition of the material dictates its initial cost, separating soil into distinct pricing tiers based on suitability for different projects. The least expensive option is typically fill dirt, which consists mainly of subsoil and clay, often containing rocks and minimal organic matter. This material is primarily used for changing the grade of land or filling large holes where structural stability is more important than fertility.
Moving up in price is standard topsoil, which represents the uppermost layer of earth, rich in minerals and organic matter necessary for plant growth. Suppliers usually screen this soil through a mesh to remove debris, large rocks, and roots. This screening process adds labor, increasing the material’s overall price compared to unscreened soil. Screened topsoil is the most common choice for general lawn repair, leveling, and establishing new turf areas.
The highest-cost category includes specialized soil blends, which are engineered for specific horticultural purposes. These premium mixtures, sometimes called triple mix or garden blends, often incorporate significant amounts of compost, peat moss, or sand. These amendments enhance drainage and nutrient content. The complex processing and higher input costs drive the price substantially above that of basic topsoil.
Purchasing methodology also plays a significant role in the cost per cubic yard. Buying soil in large, loose bulk quantities from a local landscape supplier is generally the most economical choice. Conversely, purchasing the same material bagged from a big-box retail store may cost two to three times more per cubic yard due to packaging, transportation, and retail markup.
The Critical Cost of Delivery
Once the material cost is established, transportation introduces a separate and substantial variable expense. Delivery fees are calculated independently from the price of the soil itself, reflecting the logistics of moving heavy material across distances. Suppliers typically structure this cost in one of two ways: either a flat-rate fee within a certain distance radius or a base charge with an additional fee per mile beyond that initial zone.
The fee structure often includes a minimum delivery charge, typically ranging between $50 and $150, regardless of the quantity ordered. This minimum covers the labor and fuel costs associated with dispatching the truck and driver. Many suppliers also enforce a minimum purchase requirement for bulk delivery, often requiring an order of three to five cubic yards to qualify for the service.
Larger projects requiring significant volumes of soil may necessitate booking multiple truckloads, meaning the delivery fee is applied for each trip. A standard dump truck can typically haul between 10 and 15 cubic yards of soil, depending on the truck’s capacity and local weight restrictions. It is important to confirm that the delivery site offers safe and clear access for the heavy vehicle to dump the load precisely where needed.
Calculating Your Soil Needs
Accurately determining the volume of material required prevents both expensive over-ordering and delays caused by needing a second delivery. Soil is measured in three dimensions, so calculating the necessary volume begins by determining the length, width, and desired depth of the project area. These measurements must all be converted into feet to use the standard formula for cubic yards.
The formula for calculating the necessary cubic yards is: (Length in feet \(\times\) Width in feet \(\times\) Depth in feet) / 27. This calculation divides the total volume in cubic feet by 27 because there are exactly 27 cubic feet in one cubic yard.
Projects vary significantly in the depth of soil needed, which directly impacts the number of yards required. Overseeding or top dressing an existing lawn typically requires only a shallow layer, often just 1 to 2 inches of soil. Establishing a new vegetable garden, conversely, may require a depth of 6 to 8 inches to ensure sufficient room for root development and nutrient availability.
Since the calculation requires depth in feet, inches must be converted before inputting the number into the formula. For example, a depth of 3 inches converts to 0.25 feet, while 6 inches converts to 0.5 feet. A 10-foot by 10-foot area requiring a 6-inch depth would be calculated as (10 \(\times\) 10 \(\times\) 0.5) / 27, resulting in a requirement of approximately 1.85 cubic yards.
It is generally advisable to round up the calculated volume to the nearest half-yard or full yard to account for compaction and slight variations in spreading. Having a small surplus is better than discovering a shortage mid-project, which would trigger a costly minimum delivery fee for a small refill.
