Prices for river rock per cubic yard vary widely by size, quality, and delivery distance. Typical cost drivers include rock size, screening, quarry source, and fuel surcharges. This guide provides clear low to high ranges and per unit estimates to help builders and homeowners budget effectively.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| River rock per cubic yard | $40 | $90 | $150 | Prices reflect common decorative range; larger or premium rock increases cost |
| Delivery charge | $60 | $120 | $250 | Distance and access impact cost |
| Screened vs unscreened | $0 | $10 | $25 | Screened rock offers cleaner appearance |
| Tax | $0 | $0–$8 | $20 | Depends on locality |
| Contingency and waste | $0 | $10 | $30 | Extra rock for slopes and compaction loss |
| Total installed cost per cubic yard | $100 | $210 | $350 | Includes materials plus delivery and basic prep |
Assumptions: region, rock size 1/2 to 1 inch, average access, standard excavation prep.
Overview Of Costs
River rock cost per cubic yard typically spans a broad range. For basic decorative rock delivered nearby, expect roughly $40-$120 per yard. If screening, premium colors, or larger sizes are chosen, the range shifts to about $100-$150 per yard, with delivery fees adding $60-$250 depending on distance and site access. When fully installed, total project costs commonly run in the $100-$350 per yard bracket once labor, disposal, and taxes are included.

| Delivery/Disposal | $60 | $120 | $250 | Distance, access, and disposal of old material | Truck delivery to site |
| Taxes | $0 | $5 | $20 | State/local rates apply | Sales tax where applicable |
| Warranty / Guarantee | $0 | $5 | $15 | Vendor assurances | Limited coverage on material quality |
| Overhead / Contingency | $0 | $10 | $30 | Miscellaneous project costs | Minor project overruns |
| Total per yd3 | $100 | $210 | $350 | All-in cost before site-specific tweaks |
What Drives Price
Rock size and color have a strong impact. Larger river rock or specialty colors cost more. data-formula=”labor_hours × hourly_rate”> Labor time is sensitive to site access and grading requirements. Access, slope, and edging complexity can add to both materials waste and installation time. Local haulers may apply fuel surcharges or seasonal premiums, especially in remote areas.
Ways To Save
Compare bulk suppliers and ask for locally sourced rock to cut delivery distance. Ordering slightly more rock than needed can reduce waste and per-yard handling, while choosing screened material may lower future maintenance costs. Scheduling delivery during off-peak seasons or midweek can reduce transport charges.
Regional Price Differences
Three-region comparison helps illustrate variation. In the Northeast, higher freight costs and stricter material standards tend to push per-yard prices up. The Midwest often yields competitive rates due to abundant quarries, with moderate delivery fees. The West Coast can see higher overall costs due to transport and stricter environmental requirements. Expected deltas: Northeast up to +12 percent versus national baseline, Midwest around baseline to +6 percent, West Coast +8 to +15 percent depending on proximity to sources.
Labor & Installation Time
Installed river rock projects typically require 2–6 hours of work per yard depending on site prep and edging. For a 50-yard project, labor estimates range $1,000–$3,000 depending on local rates and crew size. If edging or a contour bed is added, expect longer installation times and higher costs. Use the per-yard labor estimate to model multi-yard projects quickly.
Real-World Pricing Examples
Basic – 10 yd3, standard gray river rock, near city delivery, minimal prep. Specs: level ground, no edging. Labor hours: 8. Per-yard: $90 materials, $120 delivery, $0 screening, $0 tax. Total: roughly $1,250. Assumptions: urban delivery, standard rock size.
Mid-Range – 20 yd3, mixed color river rock, screened, standard edging, suburban site. Specs: small slope, basic prep. Labor: 15 hours. Per yd3: $110 materials, $110 delivery, $6 tax, $15 warranty. Total: about $4,200. Assumptions: screened material, edging included.
Premium – 40 yd3, premium color and size, remote delivery, heavy edging, complex bed shaping. Specs: irregular slope, larger rock, permit-ready prep. Labor: 28 hours. Per yd3: $140 materials, $180 delivery, $20 tax, $30 contingency. Total: around $9,560. Assumptions: long haul delivery, high-end rock.
Maintenance & Ownership Costs
Maintenance considerations include occasional weed control, topping off material every few years, and resealing with border edging. Over a 5-year horizon, budgeting $0.50–$1.50 per square foot per year for topping up and edging maintenance is reasonable depending on climate and weed pressure. River rock itself has a long lifespan with minimal replacement if properly sized for the bed and kept free of debris.
