What it does – The Poured Concrete Wall Cost Calculator turns the dimensions of your wall and the local concrete price into the exact amount of material you’ll need and the total cost. You simply type length, width, thickness (in inches) and the price per cubic yard; the tool instantly returns cubic feet, cubic yards, the number of 80‑lb bags (each 0.6 ft³), and the estimated expense. Knowing the cubic yards helps you order the right amount of ready‑mix, while the bag count lets you compare bulk‑mix versus ready‑mix options. The cost figure lets you budget accurately before any work begins. All results are shown in clear units so you can verify the numbers against your project plans and avoid costly over‑ or under‑ordering.

Pro tips

  • Add a 10% waste allowance to the volume.
  • Round the bag count up to the next whole bag.
  • Order concrete a day early to lock in the price.
  • Double‑check the thickness conversion from inches to feet before entering data.

Case study

Mike needed a 20 ft × 10 ft, 6 in wall. Using the calculator he saw the job required 100 ft³ (≈3.7 yd³), about 167 bags, costing $444. He ordered exactly that amount, avoided a $200 over‑order, and completed the wall on budget.

Frequently asked questions

How do I convert wall thickness from inches to feet?
Divide the thickness in inches by 12; the calculator does this automatically.
Why does the calculator show bags instead of cubic yards?
Bags help when you plan to mix concrete on‑site; each 80‑lb bag yields about 0.6 ft³.
Should I add extra concrete for waste?
Yes, add roughly 10% to the calculated volume to cover spillage and variations.
Can I use the result to order ready‑mix concrete?
Absolutely; the cubic yard figure is what ready‑mix suppliers use for quotes.
What if my wall isn’t rectangular?
Break the wall into rectangular sections, calculate each, then sum the results.
