Here's the fast way to figure it out, and what it'll cost once you know.
The Mulch Math, By Hand
Worked example: A 500 sq ft bed at 3 inches deep needs about 4.6 cubic yards of mulch.
Most beds want 2–3 inches of mulch. Deeper isn't better — too much mulch can actually smother plant roots.
What Mulch Costs Installed in 2026
Installed mulch (materials plus labor) typically runs $77 to $94 per cubic yard. Bagged mulch from a home center is more per yard than bulk delivery, but bulk usually has a delivery minimum — worth checking before you commit to bulk on a small job.
Common Mulch Job Mistakes
- Guessing depth instead of measuring it
- Not accounting for a supplier's delivery minimum on small jobs
- Estimating each bed separately and losing track of the total
- Forgetting mulch is one line item among several on a real quote
