How the Raised Garden Soil Calculator Works

The calculator uses standard volume formulas to estimate soil requirements.

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

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

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

---

Cubic Yard Conversion Formula

Garden soil is often sold in cubic yards. The calculator automatically converts cubic feet into cubic yards.

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

---

Soil Bag Formula

The calculator estimates how many 2 cubic foot soil bags are needed.

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

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

---

Soil Cost Formula

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

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

Example Raised Garden Soil Calculation

Here is a practical example.

Example Garden Dimensions

Suppose your raised garden bed measurements are:

• Length = 10 feet
• Width = 4 feet
• Depth = 12 inches
• Soil Cost = $50 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

$10\times4\times1=40\ ft^3$10×4×1=40 ft3

Total soil required = 40 cubic feet

---

Step 3: Convert to Cubic Yards

$\frac{40}{27}\approx1.48\ yd^3$2740​≈1.48 yd3

Soil volume = 1.48 cubic yards

---

Step 4: Calculate Soil Bags Needed

$\frac{40}{2}=20\ bags$240​=20 bags

Soil bags needed = 20 bags

---

Step 5: Estimate Total Soil Cost

$1.48\times50\approx74$1.48×50≈74

Estimated soil cost = $74
