How Much Does a Yard of Compost Cost? (2026 Price Guide)
A cubic yard of compost typically costs $25–$60 in bulk, or $100–$150 if you buy it in bags. Municipal compost programs often sell it for $20–$35/yard — and some cities give it away free.
Compost Prices by Type (per cubic yard)
| Compost type | Bulk price/yard | Bagged equivalent |
|---|---|---|
| Municipal/leaf compost | $20–$35 | $80–$110 |
| Mushroom compost | $25–$45 | $90–$130 |
| Organic garden compost | $35–$60 | $120–$150 |
| Worm castings (vermicompost) | $200+ | sold by bag only |
Prices vary by region and season — spring demand pushes prices up.
Bulk vs. Bags: The Real Math
A cubic yard = 27 cubic feet. At a 2 cu-ft bag size that’s 13.5 bags per yard. Bulk: 1 yard at $38 = $38. Bags: 14 bags (rounded up) at ~$9 each = $126. Bulk delivery wins whenever you need more than about half a yard. Bags make sense for small top-dressing jobs under ~10 bags. Don’t forget delivery fees: bulk suppliers typically charge $50–$100 per truckload, which stings on small orders but fades into the per-yard price on 3+ yard orders.
How Much Compost Do You Actually Need?
- Lawn top-dressing (0.5 inch deep): 1 yard covers 648 sq ft
- Existing garden beds (2 inches): 1 yard covers 162 sq ft
- New garden beds (3–4 inches): 1 yard covers 81–108 sq ft
Formula: Length (ft) × Width (ft) × Depth (in) ÷ 324 = cubic yards needed.
Example: a 20×10 ft bed at 3 inches = 200 × 3 ÷ 324 = 1.85 cubic yards → order 2 yards.

Money-Saving Tips
- Check your municipality first. Many cities compost yard waste and sell it back to residents cheap — sometimes free on community compost days.
- Buy in fall. Demand (and prices) peak in spring; fall orders are often discounted.
- Split a truckload with a neighbor. Delivery fees are per trip, not per yard.
- Ask what’s in it. The cheapest compost isn’t always the best — ask for a lab analysis or at least the feedstock source. Good compost smells earthy, not sour.
Frequently Asked Questions
How many bags of compost are in a cubic yard?
About 14 bags of 2 cu-ft size (27 ÷ 2 = 13.5, rounded up). For 1 cu-ft bags it’s 27 bags; for 1.5 cu-ft bags it’s 18.
Is bulk compost cheaper than bags?
Almost always — typically 2–3x cheaper per yard. Bags only win for very small jobs where delivery fees would dominate.
How much does it cost to compost at home?
A basic bin setup costs $30–$80 one-time. After that, homemade compost is essentially free — just kitchen scraps, leaves, and patience (3–6 months per batch).
Can I get free compost?
Yes — check your city’s waste management site for free compost days, and ask local tree services for free wood chips (different material, but free mulch).
