Excavation Cost Per Cubic Yard: What Contractors Charge

Excavation costs $10–$50+ per cubic yard depending on soil type, project complexity, and hauling. Here is what contractors actually charge and why.

Updated

Excavation cost per cubic yard ranges from $10 for loose topsoil to $50 or more for solid rock. That number is the key figure when comparing contractor bids — it levels the playing field regardless of how differently contractors scope a project. Here's what goes into the per-yard rate and how to use it to evaluate quotes intelligently.


Why Cost Per Cubic Yard Is the Right Number to Compare


When three contractors bid the same job, their total prices often differ by 20–40%. Some of that is margin. Some is different equipment assumptions. But a lot comes down to how many cubic yards each contractor estimates — and those estimates can legitimately differ by 10–15% based on how precisely they measure.


Comparing the per-cubic-yard rate cuts through all of that. If Contractor A bids $22/cu yd and Contractor B bids $34/cu yd for the same soil type, you now have a specific question to ask Contractor B: what accounts for the premium?


Use the excavation cost calculator on this site to estimate your project volume in cubic yards, then divide each contractor's total by that number to normalize their bids.


Current Rates by Soil Type (RSMeans 2026)


These are the base excavation rates without hauling, sourced from RSMeans 2026 construction cost data:


  • Topsoil / loose fill — $8–$12 per cubic yard
  • Sandy or silty soil — $9–$14 per cubic yard
  • Clay / compacted earth — $12–$18 per cubic yard
  • Hardpan or dense gravel — $15–$22 per cubic yard
  • Soft rock / shale — $30–$45 per cubic yard
  • Hard rock (requires blasting or hammering) — $45–$75+ per cubic yard

    • These are equipment-and-operator rates for a standard backhoe or excavator. Labor-only rates (hand-digging or confined spaces) run 4–6× higher.


    What's Included in a Per-Yard Rate


    A typical contractor per-yard rate includes:


    - Equipment depreciation and maintenance

    - Operator labor

    - Fuel

    - Mobilization cost spread across the total volume


    It does NOT typically include:


    - Hauling and disposal (billed separately, usually $8–$20/cu yd for standard fill)

    - OSHA shoring for deep excavations

    - Dewatering (pumping groundwater)

    - Permits

    - Erosion control


    When you're comparing quotes, make sure you're looking at what each contractor has included or excluded from their per-yard number.


    Project Type Adds a Multiplier


    Beyond soil type, project complexity adjusts the effective rate. Contractors don't always break this out as a separate line — they often just build it into their per-yard figure. Here's how typical adjustments look:


  • General excavation — baseline rate (1.00×)
  • Foundation / basement — 1.10–1.20× (precise walls, no room for variation)
  • Pool excavation — 1.15–1.25× (curved profile, specialized digging pattern)
  • Utility trench — 1.05–1.15× (narrow cut, careful work around existing utilities)
  • Land grading — 0.85–0.95× (wide-open work, maximum production rate)

    • A contractor pricing foundation excavation through clay at $15/cu yd base rate and 1.15× multiplier is effectively charging $17.25/cu yd all-in for the excavation portion — before hauling.


    A Real Example: Breaking Down a Quote


    Here's how to decode a contractor bid. Suppose you get a quote for a 40×30 ft, 4 ft deep foundation excavation in clay soil:


    Volume: (40 × 30 × 4) ÷ 27 = 177.8 cubic yards


    Contractor quote: $5,800 total (includes hauling)


    To find effective per-yard rate:

    - Subtract hauling estimate: 177.8 cu yd × $12/cu yd (standard rate) = $2,133 hauling

    - Excavation-only cost: $5,800 − $2,133 = $3,667

    - Per cubic yard: $3,667 ÷ 177.8 = $20.62/cu yd


    For clay with foundation complexity, $20.62/cu yd is reasonable. If another contractor quotes $28/cu yd on the same volume, you know to ask what's different.


    You can run this math yourself using the excavation cost calculator — enter your dimensions and compare the "cost per cubic yard" result against contractor bids.


    Regional Variation in Per-Yard Rates


    National averages shift significantly by region. Based on 2026 contractor survey data:


  • Northeast (CT, MA, NY, NJ) — 20–35% above national average
  • West Coast (CA, WA, OR) — 15–30% above average
  • Mid-Atlantic (DC, PA, VA, MD) — 5–15% above average
  • Southeast — At or slightly below average
  • Midwest — 5–15% below average
  • Mountain West — Varies significantly; urban areas (Denver, SLC) near average; rural areas below

    • Labor costs, permitting requirements, and equipment availability all drive regional variation. A $15/cu yd rate in Ohio might translate to $20/cu yd in New Jersey for an identical project.


    How to Use Per-Yard Rates to Spot Problems


    A per-yard rate significantly below the range for your soil type usually means one of these things:


    - The contractor is underestimating the volume (a common error that leads to change orders)

    - They're planning to use equipment that's too small for the job

    - They're new to the market and pricing aggressively to win work (not necessarily bad, but worth understanding)

    - They're planning to cut corners on safety or compliance


    A rate significantly above range doesn't always mean overpriced. Sometimes it reflects:


    - A contractor with premium equipment who works faster

    - Accurate accounting for difficult site access

    - Inclusion of items (permits, erosion control, dewatering) that lower quotes exclude


    The per-yard rate is a starting point for the conversation, not the final word. But knowing what's normal for your soil type puts you in a much stronger position to ask the right questions.


    Reducing Your Per-Yard Cost


    A few choices directly lower the per-yard rate:


  • Schedule in dry season — Wet soil is heavier and slower to load; dewatering pumps add to cost
  • Choose accessible equipment staging — Give your contractor room to work efficiently
  • Consolidate excavation work — Mobilization is a fixed cost spread over volume; more cubic yards usually means a lower unit rate
  • Keep spoil on site — Eliminating or reducing hauling cuts a significant separate cost; standard hauling at $12/cu yd adds 60–80% on top of the excavation rate in softer soils
