How this calculator works
Enter the approximate length and width of your planting beds and the mulch depth you intend to use. Compare bulk and bag prices supplied by your retailer.
Formula
Length × width × depth in inches ÷ 12 ÷ 27, plus an extra allowance.
Before you use the result
Calculator outputs are estimates based on the numbers you provide. Replace the examples with measurements, costs, rates, or product information appropriate to your situation.
Different mulch materials settle differently. Avoid piling mulch against trunks or buildings; confirm application depth for your plants.
