Cut and Fill Calculator

Earthwork balance: surplus to export or deficit to import, shrinkage included.

Quick answer: Balance = cut volume − (fill required × shrink factor). Fill compacts 10–15% smaller than bank, so 100 cy of fill space needs ~112 cy of cut. Positive result = export; negative = import.

How to use this calculator

  1. Enter Cut volume in cu yd.
  2. Enter Fill required in cu yd.
  3. Enter Shrinkage in %.
  4. Press Calculate. The highlighted row is your order quantity; the note beneath it translates the number into real-world terms.

Formula & constants

Balance = cut volume − (fill required × shrink factor). Fill compacts 10–15% smaller than bank, so 100 cy of fill space needs ~112 cy of cut. Positive result = export; negative = import. Every default in the fields above is editable — when your supplier’s spec sheet lists a different density, coverage rate or price, enter that number instead. The waste and compaction allowances follow common trade practice; see our methodology page for the derivation of each formula and the standards it references.

Worked example. With cut volume = 10 cu yd, fill required = 10 cu yd, shrinkage = 12 %, the calculator returns:
Net balance-1 cu yd
ActionImport 1 cy

Where this fits in the project

Earthwork precedes everything: dig volumes set the budget for hauling and determine imported fill or base gravel. Bank volume expands when dug (swell) and imported fill shrinks when compacted — use the truckload calculator on loose volume, not bank volume.

How this connects to your project

No quantity stands alone — each material in the chain depends on the ones around it. These are the planning steps that pair with the cut and fill calculator:

Frequently asked questions

Why does fill ‘shrink’?

Compaction densifies soil beyond its bank state — a compacted yard came from more than a yard of cut.

What is a balanced site?

Grading designed so cut equals adjusted fill — zero import/export, the cheapest earthwork outcome.

Estimates are for planning. Material densities, coverage rates and prices vary by region and supplier — confirm final quantities before ordering, and check local code where structural or electrical work is involved.
