For amending beds, spread 1–3 inches of compost and work it into the top 6 inches of soil. For lawn top-dressing, ¼–½ inch is plenty.

The math: 500 sq ft × depth in feet ÷ 27 = cubic yards. One cubic yard of compost covers 324 sq ft at 1" · 162 sq ft at 2" · 108 sq ft at 3".

Compost compresses — if it will sit in a pile for weeks before spreading, order about 10% extra.
