Construction estimate note

Concrete and masonry calculators on ToolsBing are planning estimates only. Confirm dimensions, material yields, reinforcement, mix design, local code requirements, supplier coverage, delivery limits, and site conditions with a qualified contractor, engineer, supplier, or inspector before ordering or building.

MeaningPlanning quantity

This is a buying or planning estimate before supplier package-size checks.

Next stepVerify before ordering

Recheck dimensions, waste factor, material yield, and local construction requirements.

Formula and assumptions

Quantity = measured area or volume adjusted by coverage, yield, and waste assumptions

Use this result as an early estimate. Real projects may require mix design, reinforcement review, subgrade preparation, moisture control, curing, delivery minimums, compaction, local code checks, and professional supervision.

Known input

30 ft length, 12 ft width, 4 in thickness, 10% waste.

Expected result

Displayed concrete yardage should be about 4.889 cubic yards.

Method check

Cubic yards = length x width x thickness(in) / 12 / 27, then apply waste allowance. Allow +/- 0.01 cubic yards for rounding.
