Estimate how many cubic yards of fill dirt you need. Each dimension has its own unit selector (in/ft/yd/m).
Fill dirt is sold by the cubic yard. Measure each area's volume (length x width x average fill depth), divide by 27 for cubic yards, then add 10-20% for compaction. Fill dirt is cheaper than topsoil - use it for structure and reserve topsoil for the planting layer. Switch units on any field.
Use the dirt calculator for grading, backfill, low spots and general fill planning. It converts the measured fill volume to cubic yards and applies an allowance for settling or compaction.
Start with the calculator that matches how your material is sold: area, length, volume, count, weight or electrical load. Enter one work area at a time, use the unit selector beside each measurement, then review the order quantity and cost fields before comparing supplier quotes.
Most calculators can save the current estimate in your browser, reload named estimates, print a copy, switch to dark mode or create a shareable link. Those tools are intended for planning and communication; always confirm final quantities, coverage rates, density, code requirements and pricing with the supplier or contractor responsible for the work.
