How we price

Every price on this site comes from a published source that we name, link and date. We last checked all of them on September 23, 2026.

The rules

• Sourced or not published. If we can't point to where a number comes from, it isn't on the site. That's why there is no 40 lb bag price and no state or city pricing.
• One primary source per calculator figure. The calculators use a single dated source for each price and name it in the result. The guides show every source we found, including the ones that disagree.
• Disagreements stay visible. When sources differ widely, as they do on concrete removal, we show both rather than averaging them.
• Computed figures are labeled. Costs by size are the area multiplied by a published per-square-foot range. They inherit that source's assumptions.
• Search listings are marked. Some sites block automated checks. Where a figure comes from the page's search listing rather than the page itself, the source list says so.

How the calculators work

Volume is length × width × thickness, converted to cubic yards (27 cubic feet each). Round shapes use π × radius² × depth. Steps are stacked blocks: width × run × rise × n(n + 1) ÷ 2. Blocks are counted at 1.125 per square foot of wall, the face of a standard 16 × 8 in unit with its mortar joint.

Bag counts divide the volume by Quikrete's published yield and round up. Waste is an explicit setting, 10% by default for concrete and 5% for blocks. Installed prices use the area without waste.

The figures the calculators use

What we don't do

• We don't publish local prices. National ranges can be far from what a contractor in your area charges.
• We don't give engineering advice: thickness, reinforcement, footing size and code requirements belong to your contractor, engineer or building department.
• We aren't paid by any contractor, supplier or retailer named on this site.
