How much mulch for 500 square feet?
Quick Answer
For 500 square feet at 3 inches deep, you need approximately 4.6 cubic yards of mulch or about 62 bags (2 cu ft bags). At 2 inches deep, you need 3.1 cubic yards or 42 bags. Buying in bulk (by the cubic yard) is significantly cheaper than bagged mulch for this quantity.
Quick Reference Table
| Depth | Mulch for 500 sq ft |
|---|---|
| 2 inches | 3.1 yd³ / 42 bags (2 cu ft) |
| 3 inches | 4.6 yd³ / 62 bags (2 cu ft) |
| 4 inches | 6.2 yd³ / 83 bags (2 cu ft) |
How to Calculate It Yourself
- 1
Calculate volume: 500 sq ft × (3" ÷ 12) = 500 × 0.25 = 125 cu ft.
- 2
Convert to cubic yards: 125 ÷ 27 = 4.63 yd³.
- 3
In bags: 125 cu ft ÷ 2 cu ft/bag = 62.5 → 63 bags.
- 4
Order 5 cubic yards in bulk for a standard delivery (most companies have a 3 yd minimum).
Pro Tip
At 500 sq ft, bulk mulch saves significantly over bags. Expect to pay $25–45 per cubic yard for bulk vs. $4–6 per bag ($248–378 for 62 bags). You save $100+ by going bulk.
