How the Raised Garden Bed Soil Calculator Works

The calculator uses standard garden volume formulas to estimate the amount of soil required.

Soil Volume Formula

The total soil volume is calculated using:

$V=L\times W\times D$V=L×W×D

Where:

• V = Volume
• L = Length
• W = Width
• D = Depth

---

Depth Conversion Formula

Because soil depth is entered in inches, the calculator converts inches into feet first.

$Depth\ in\ Feet=\frac{Depth\ in\ Inches}{12}$Depth in Feet=12Depth in Inches​

---

Cubic Yard Conversion Formula

Bulk garden soil is usually sold in cubic yards. The calculator converts cubic feet into cubic yards automatically.

$Cubic\ Yards=\frac{Cubic\ Feet}{27}$Cubic Yards=27Cubic Feet​

---

Soil Bag Formula

The calculator estimates the number of 2 cubic foot soil bags required.

$Bags\ Needed=\frac{Cubic\ Feet}{2}$Bags Needed=2Cubic Feet​

The result is rounded up to ensure enough soil is available.

---

Soil Cost Formula

If the soil price per cubic yard is entered, the calculator estimates the total cost.

$Total\ Cost=Cubic\ Yards\times Soil\ Price$Total Cost=Cubic Yards×Soil Price

Example Raised Garden Bed Soil Calculation

Here is a practical example to understand how the calculator works.

Example Dimensions

Suppose your raised garden bed measurements are:

• Length = 8 feet
• Width = 4 feet
• Soil Depth = 12 inches
• Soil Price = $45 per cubic yard

---

Step 1: Convert Depth into Feet

$\frac{12}{12}=1\ foot$1212​=1 foot

Depth in feet = 1 foot

---

Step 2: Calculate Soil Volume

$8\times4\times1=32\ ft^3$8×4×1=32 ft3

Total soil volume = 32 cubic feet

---

Step 3: Convert to Cubic Yards

$\frac{32}{27}\approx1.19\ yd^3$2732​≈1.19 yd3

Soil volume = 1.19 cubic yards

---

Step 4: Calculate Soil Bags Needed

$\frac{32}{2}=16\ bags$232​=16 bags

Bags required = 16 bags

---

Step 5: Calculate Total Soil Cost

$1.19\times45\approx53.55$1.19×45≈53.55

Estimated soil cost = $53.55
