How to Use This Calculator
- Enter Trench Length, Width, and Depth in feet.
- If the trench has sloped walls, enter the Slope Ratio (H:V) — this widens the trench at the top.
- Read Volume in cu ft and cu yd — use the cubic yard figure when ordering fill or paying for spoil disposal.
- Use Truck Loads (10 yd) to schedule haul trucks and Excavation Time to plan equipment rental.
- Feed the cu yd output into the Excavation Cost or Backfill Quantity calculators for budget estimates.
