Calculate cut or fill volume in cubic yards from existing and design elevations. Essential for grading contractors, civil engineers, and earthwork crews estimating material quantities.
GPS machine control systems and grade lasers automate cut/fill operations on dozers and scrapers. Shop grading equipment at Express Tools.
Shop Express Tools →An earthwork cut fill calculator is a core tool for grading contractors and civil engineers estimating material quantities on road, site, and pad projects. Cut refers to soil removed where existing grade is above design; fill is material added where existing is below design. Balancing cut and fill on a project minimizes hauling costs—the goal is to reuse excavated material as fill elsewhere on site. Always apply swell factor (10–30%) to cut volumes and shrinkage factor (10–15%) to fill volumes for accurate truck counts and compaction estimates. Use this cut fill calculator during takeoff to get cubic yard volumes before mobilizing equipment.

The basic method multiplies the area by the average depth difference between existing and design elevation. For a 100×100 ft area with 1.5 ft average cut, that's 10,000 SF × 1.5 ft ÷ 27 = 556 cubic yards.
When soil is excavated (cut), it expands 10–30% in volume (swell). When compacted as fill, it shrinks 10–15%. Always apply these factors to your raw calculator results for accurate material estimates.
GPS machine guidance systems (Trimble GCS900, Topcon MC-Max) automate cut/fill operations on dozers and scrapers. Grade checkers use total stations or GPS rovers to verify achieved grade against design.
