Use our compost calculator to figure out how much soil you will need for your garden. Calculate based on your unique garden layout! Or, see our Rates at a Glance for your project-type.
To start calculating, select "Project Type," then add shapes and areas (dimensions) that best represent your garden. There are geometric shapes at the bottom for help determining the measurements for common garden areas. You can add multiple shapes and dimensions in our soil calculator! Click "Calculate" to see how many bags of compost your project will most likely require. Note: 1 BigYellowBag = 1 cubic yard and 1 Small Bag = 1/2 cubic foot.
