One cubic yard of mulch contains 27 cubic feet. Divide that by your bag's size to get the count. The most common bag at Home Depot and most retailers is 2 cubic feet, so you need 13.5 bags per yard — round up to 14 since you can't buy half a bag.

Bags vs. Bulk: The Real Cost Comparison
Bags are convenient but expensive. Here's the honest math at typical prices:
🛍 Bagged (2 cu ft, $5/bag)
Per cu ft: $2.50
Per cu yd: ~$68
✓ No truck needed
✓ Buy exactly what you need
✗ Much more expensive
🚛 Bulk ($35/yard)
Per cu ft: $1.30
Per cu yd: $35
✓ 50% cheaper
✓ Better for large areas
✗ Need truck or delivery
Rule of thumb: if you need more than 1.5 cubic yards (about 20 bags), order bulk.
