Find how many cubic yards of material you need. Each dimension has its own unit selector (in/ft/yd/m).
A cubic yard holds 27 cubic feet. Multiply each area's length, width and depth (the calculator converts your chosen units to feet), then divide by 27. Inches of depth become feet automatically. Add a waste allowance and a price per yard for a quick order estimate.
Use the cubic yard calculator for bulk materials such as soil, gravel, mulch, compost and concrete. It totals multiple areas and adds a waste or settling allowance before estimating order quantity and cost.
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.
