How many bags of mulch for 500 sq ft, 3 inches deep?

Data checked October 2026

Short answer

500 sq ft of mulch 3 in deep takes 125 cu ft (4.63 cu yd) — 63 bags of 2 cu ft, 84 bags of 1.5 cu ft or 42 bags of 3 cu ft.

Label check: a 2 cu ft bag covers 8 sq ft at 3 in, and 500 ÷ 8 = 62.5 → 63 bags.
With 10% extra for settling and uneven beds: 69 × 2 cu ft or 92 × 1.5 cu ft.
Cost at Mulch Pros' Oct 2026 prices: about $230 in 2 cu ft bags vs $232 for 4.63 cu yd of bulk dyed mulch delivered — bags are cheaper here.
Weight: about 2,778 lb of wood mulch (1.4 tons) — more after rain.
Depth: MSU Extension recommends 2–4 in for dyed mulch; 3 in is also the depth bag labels quote coverage at.
500 sq ft is a large front-yard bed system — right around the size where bulk delivery starts to beat bags.

How this was worked out

500 sq ft × 3 in ÷ 12 = 125 cu ft. Divide by the bag size — 125 ÷ 2 = 62.5, rounded up to 63 bags — or by 27 for 4.63 cubic yards.

With bags at $3.65 and bulk at $33.95 a yard plus $75 delivery, bulk pays off from about 4.9 cu yd — about 529 sq ft at 3 in. At 4.63 cu yd you are below it, so bags are cheaper and easier to carry to the beds.
