How to Use This Calculator

Enter Bank Volume in cu yd — the in-place volume you are moving.
Select Soil Type (clay, sandy loam, gravel, etc.) to apply the correct swell and shrink factors.
Enter Target Compaction % (typically 95–98% of standard Proctor for structural fills).
Review Loose Volume (what to haul) and Compacted Volume (what you'll end up with in place).
Use Water Needed in gallons and Recommended Lift Thickness to plan compaction equipment passes.
