Concrete Floor Calculator

This one is aimed at an interior floor rather than a single rectangle of concrete: give it the total square footage, or the length and width of up to three rooms, plus the slab thickness. It returns the volume in cubic yards, cubic feet and cubic metres, how many ready-mix loads that is at your truck capacity, what the concrete costs at your price per yard, and the bag count for a 40, 60 or 80 pound mix. A waste allowance is added on top because a screeded floor never comes out at the theoretical volume. Vapour barrier, base gravel, mesh and rebar are not counted, and a short-load fee from the plant is not either.

Units

Feet, inches and cubic yards Metres, centimetres and cubic metres

Bag sizes stay 40, 60 and 80 lb, because that is how bagged mix is sold.

Floor Area (sq ft) *

Square feet, or square metres when Metric is selected.

Slab Thickness (in) *

Waste Allowance (%)

Ready-Mix Price ($)

Per cubic yard, or per cubic metre when Metric is selected. Leave blank if you only want the volume. Short-load and delivery surcharges are not included.

Truck Capacity (cu yd)

Cubic yards, or cubic metres when Metric is selected. A full ready-mix truck usually carries 8 to 10 cubic yards, about 6 to 7.6 cubic metres.
