Concrete & Foundation Calculators
Concrete is priced two ways at once — by the cubic yard from a truck and by the bag from a pallet — and the crossover between them decides most small jobs. These calculators give the volume, the waste allowance, the reinforcement and the delivered cost for slabs, footings, driveways and steps.
There are 15 calculators here: Concrete Strip Footing Calculator (concrete volume and cost for continuous strip footings), Concrete Slab Cost Calculator (concrete volume, bag count and slab cost), Concrete Stairs & Steps Calculator (concrete volume, step layout and cost for poured stairs), Concrete Truck Load & Short-Load Fee Calculator (truck count, short-load fees and total delivered cost), and 11 more below.
They all work the same way: quantity first, then a waste allowance you can change, then a price built from verified figures and adjusted for your state. Cost is always a range rather than a single number, and every assumption behind it is printed on the page with its source and the date it was last checked.
Topics in Concrete & Foundation Calculators
- Concrete Slab CalculatorsA slab is volume plus reinforcement plus the thickened edge nobody remembers to price. These run the common sizes end to end, so you can compare a 20x20 patio against a 24x24 garage pad without redoing the arithmetic each time.7 calculators
- Footing & Pier CalculatorsFootings carry the load a slab only spreads. Continuous trench footings and cylindrical pier footings are priced from different shapes, so they are calculated separately here.2 calculators
- Concrete Driveway CalculatorsA driveway is a slab that carries vehicle loads, which means more thickness, more reinforcement and control joints on a tighter spacing than a patio of the same area.2 calculators
- Ready-Mix & Delivery CalculatorsOrdering concrete is its own decision: how many trucks, how big the short-load fee is, and the yardage above which bagging it yourself stops making sense.2 calculators
- Concrete Stairs & Coating CalculatorsWhat happens to concrete after the pour: formed steps priced by riser, and coatings priced by coverage rate rather than volume.2 calculators
