Estimate the cubic yards and bags of mulch your beds need. Each dimension has its own unit selector (in/ft/yd/m).
Measure each bed and find its volume (length x width x depth), divide by 27 for cubic yards. A 3-inch layer is typical. Bagged mulch comes in 1.5, 2 or 3 cubic-foot bags - use the bag preset, and divide the total cubic feet by the bag size for the number of bags. Switch any field's unit as needed.
Use the mulch calculator to estimate cubic yards, cubic feet, bags and cost for beds, tree rings and landscape areas. It converts depth and area into volume, then compares bag size and price.
Start with the calculator that matches how your material is sold: area, length, volume, count, weight or electrical load. Enter one work area at a time, use the unit selector beside each measurement, then review the order quantity and cost fields before comparing supplier quotes.
Most calculators can save the current estimate in your browser, reload named estimates, print a copy, switch to dark mode or create a shareable link. Those tools are intended for planning and communication; always confirm final quantities, coverage rates, density, code requirements and pricing with the supplier or contractor responsible for the work.
