How to price concrete work
Yards and square feet in the same estimate
Homeowners think in square feet; the plant bills in cubic yards. The library prices flatwork per square foot with the concrete inside the unit, and ready-mix per yard as a separate item for footings, walls and short loads. Use the slab calculator to get quantities, then "Turn this into an estimate" to bring the line items in with your labor rate.
Base, reinforcement and finish are separate decisions
A 4-inch broom-finish slab on 4 inches of compacted gravel with mesh is the baseline; rebar, thickened edges, vapor barriers, air-entrained mix and decorative finishes are their own lines so an upgrade shows its price. Cold-weather additives, blankets and pump time belong on the estimate when the season or the site calls for them.
Demolition and access
Removing an old slab is priced per square foot by thickness with haul-away per ton and a dumpster row; a line pump or boom pump is a half-day charge. Listing them prevents the "you never said the pump was extra" call.
Compared with spreadsheets and full suites
Concrete-specific takeoff software targets commercial bidding, and generic field apps don't know what a cubic yard is. American Build Rate's concrete library and slab calculator share one engine, so a quantity calculated on the public page becomes an estimate line with your rates, and drafts never count against the five free sends a month. For what the general field apps charge, dated, see our contractor software pricing page.
Pricing
Free: unlimited drafts, 5 tracked sends a month, PDFs with a one-line footer. Pro $13/mo or $130/yr: unlimited sends, no footer, 4 people on one price book, the website widget. Details on the pricing page.
Questions from concrete contractors
Does the estimate use the same math as the calculator?
Yes. The quantities (yards, bags, mesh, rebar, gravel) come from the same engine as the calculator pages; the estimate applies your labor rate, markup and tax instead of the national estimates on the public pages.
Can I price stamped or exposed-aggregate work?
Both are library items per square foot on top of the base slab; integral color is priced per yard.
How do short loads get handled?
The "Short-load fee" item is a fixed material charge; the calculator flags likely short loads when the order is under the plant minimum.
