Mulch Calculator
Calculate exactly how much mulch you need for your garden beds with our comprehensive calculator. Determine cubic yards, bags needed, and total cost based on area and depth.
Step 1: Area Measurement
Recommended Mulch Depth
For most garden beds, 2-4 inches of mulch is ideal. Too little won’t suppress weeds effectively, while too much can prevent water from reaching plant roots.
Step 2: Mulch Type & Cost
Mulch Coverage Guide
One cubic yard of mulch covers approximately 100 square feet at 3 inches deep. Bags typically contain 2-3 cubic feet. Always add 5-10% extra for waste and settling.

Mulch Calculation Formula
Cubic Yards = (Length × Width × (Depth/12)) / 27 × (1 + Waste Factor)
To calculate mulch needed: Multiply length and width to get area, convert depth from inches to feet, calculate cubic feet, convert to cubic yards, then add waste factor percentage.
