Concrete Slab Cost Calculator
A concrete slab cost calculator estimates the price of a slab by calculating its volume in cubic yards (length times width times thickness) and multiplying by your price per yard, or by area times a price per square foot. Enter your slab dimensions and price below for an estimated slab cost.
also supports area x price_per_sqft mode. Price user-entered.
Enter the dimensions or cubic yards to estimate the cost.

How Much Does a Concrete Slab Cost?
A concrete slab costs its volume in cubic yards times your price per yard, plus finishing and labor. A 20 by 20 foot slab at 4 inches thick is about 4.9 cubic yards. Some estimate by square foot instead, where the price includes material and basic finishing. The calculator works either way, using the price you enter, since slab pricing varies with thickness, finish, reinforcement and region.
What Is Included in a Concrete Slab Price?
A concrete slab price typically includes the concrete itself, the base preparation (gravel and grading), forming, pouring, finishing and sometimes reinforcement like rebar or wire mesh. A bare material estimate (yards times price per yard) is lower than a finished, installed square-foot price. The calculator lets you estimate either the material or the installed cost depending on which price you enter, so match the price to what it covers.
