How to Use This Calculator

Enter the pool's finished interior length and width in feet.
Set the shallow end and deep end finished depths in feet.
Select pool shape: 1 = rectangular, 2 = oval/kidney, 3 = freeform.
Enter the over-dig clearance (typically 1.5 ft) for forming access around the shell.
Enter the gunite/shotcrete shell thickness in inches (6-9 inches for residential pools).
Review Excavation Volume (cu yd), Haul-Away Volume, and Dump Truck Loads to get accurate excavation bids.

How the result changes with Pool length (ft)

Pool length (ft): Interior finished length of the pool.
Pool width (ft): Interior finished width of the pool.
Shallow end depth (ft): Finished depth at the shallow end.
Deep end depth (ft): Finished depth at the deep end.
Pool shape (1=rect, 2=oval, 3=free): 1 = Rectangular, 2 = Oval/Kidney, 3 = Freeform. Adjusts volume by shape factor.
Over-dig clearance (ft): Extra clearance around pool for forming and structural access. Typically 1-2 feet.
Shell thickness (in): Gunite/shotcrete shell thickness. Residential pools typically use 6-9 inches.

Excavation volume (cu yd): In-situ (bank) cubic yards of earth to remove.
Haul-away volume (cu yd): Volume after swell factor (25%) for loose hauling.
Dump truck loads: Standard 10 cu yd tandem dump truck loads needed.
Estimated weight (tons): Approximate weight of excavated material at 2,800 lbs/cu yd.
Excavation length (ft): Total dig length including shell thickness and over-dig.
Excavation width (ft): Total dig width including shell thickness and over-dig.
Average dig depth (ft): Average excavation depth including shell and gravel base.
Volume (cu ft): Total excavation volume in cubic feet.

Calculate Excavation volume
Excavation volume = volumeCuFt / 27
165.9 = 165.9
Calculate Haul-away volume
Haul-away volume = volumeCuYd * swellFactor
207.4 = 207.4
