Calculate how much soil you need for raised garden beds, planter boxes, and growing beds. Estimate cubic feet, cubic yards, bags of soil, soil mix ingredients, compost, topsoil, potting mix, weight, and total raised bed soil cost.
Raised bed dimensions:
The calculator multiplies bed length by width by soil depth to estimate soil volume for one bed.
Multiple raised beds:
Enter the number of beds to calculate the total soil needed for several beds of the same size.
Soil mix ingredients:
Enter compost, topsoil, and potting mix percentages to estimate how much of each ingredient is needed.
Known volume:
Enter an existing soil volume to convert it into cubic feet, cubic yards, cubic meters, gallons, liters, bags, weight, and cost.
A raised bed soil calculator helps estimate how much soil, compost, topsoil, and potting mix you need before filling garden beds.
It can be useful for vegetable gardens, flower beds, herb beds, square foot gardens, planter boxes, container beds, and bulk soil delivery planning.
Your result shows raised bed soil volume before and after extra allowance, cubic feet, cubic yards, cubic meters, gallons, liters, bags needed, estimated soil weight, soil mix ingredient amounts, bag cost, bulk soil cost, and total cost.
Multiply the bed length by width by soil depth using the same unit. Convert the result to cubic feet, cubic yards, or bags as needed.
Many raised vegetable beds use 10 to 12 inches of soil, while deeper-rooted plants may benefit from 18 inches or more.
One cubic yard equals 27 cubic feet.
Yes. Adding 5% to 15% extra soil can help account for settling, compaction, uneven filling, spills, and measurement differences.
