About the Mulch Calculator
This mulch calculator computes the volume of mulch required for any garden bed or landscape area at your specified depth, in cubic yards (for bulk delivery) and equivalent bags (for bagged mulch from a store). Enter the bed dimensions and mulch depth to see the exact amount needed with an optional 10% overage for uneven coverage. Add multiple beds to calculate a total order. Built for homeowners, landscapers, and gardeners planning mulch installation or annual replenishment.
