About Mulch Calculator
Multiply your bed area by the mulch depth and this tool returns cubic yards plus a bag count at the standard 2-cu-ft bag size (editable for 3-cu-ft bags). A waste factor covers settling and uneven spreading.
Common uses
- Decide between bagged mulch and a bulk delivery
- Refresh beds at 2 in and know the bag count before the store run
Example
Input
200 sq ft at 3 in deep, 10% waste
Output
1.85 yd³ exact → order 2.04 yd³ = 28 bags (2 cu ft)
Limitations
- Mulch compresses over time; the first fill often needs the full 3–4 in
