about
Numbers with their receipts.
CostPerFoot works out how much material a home project needs and what it will cost. You type the measurements; the page does the arithmetic and answers in the units the material is actually sold in — cubic yards, tons, bags, bundles.
Every material figure on this site carries its source and the date we read it, and it is a range rather than a single number, because a material weighs different amounts loose and compacted, dry and wet. Where no manufacturer or authority publishes a figure, the page says the number is our own criterion instead of dressing it up as a sourced fact.
Your supplier has the last word. Aggregates vary by quarry, and the weight on their ticket is the one you are paying for.
It works out quantities from the dimensions you give it. It never tells you what size to build: no beam spans, no footing sizes, no load-bearing answers, no electrical or gas sizing. A wrong quantity costs money and a second trip to the merchant; a wrong load-bearing answer hurts somebody. This site takes the first risk only, and none of it is engineering, legal or tax advice.
Nobody on this site is presented as a licensed professional, and no page carries a review badge, because there is no engineer here to sign one. What the pages carry instead is the arithmetic, the sources, and the date a person last checked the arithmetic by hand.
If a number here is wrong, that is worth more to us than most of our traffic. A contact address goes here before the site is launched.
