Curb is flatwork stood on its side, and it prices like it: by the linear foot, with the labor hiding in the forms. The calculator above uses an example rate of $35 per linear foot. Length times rate gets you the base number; the profile and the site decide whether that rate is right.
Two faces and a top, all formed
A slab has one finished surface and the ground does most of the forming. A curb gets formed on both faces, held to line and grade, and finished on top and on every exposed edge, all on a few inches of width. That is why a foot of curb costs several times a foot-wide strip of slab. Batter, height, and profile (straight face, rolled, mower curb around beds) change forming time, so if you carry one curb rate, make sure it reflects the profile you actually pour most.
Quick math at the example rate: 60 feet of landscape curb is 60 x $35, which is $2,100. Small total, full crew day once you count forming and stripping. This is exactly the kind of job where quoting fast on-site wins the work before a competitor calls back.
Machine-extruded vs hand-formed
Extruders shine on long, straight, uninterrupted runs, which is why commercial lots and subdivisions get machine curb. Most residential curb work is the opposite: short runs, tight radii, tie-ins to existing curb, and repairs. That is hand-form territory, and hand-formed feet cost more to produce. If you run both methods, they deserve separate rates. If you only hand-form, do not let a machine-curb price from a big outfit set the customer’s expectations for a 40 foot repair.
Aprons and radius work
Driveway aprons are where curb work and flatwork meet: the curb drops through a transition, the apron ties the street to the driveway, and the radii on each side are all hand work. Radius curb is slower per foot than straight curb, always. Count the transitions and returns when you measure, not just the run, and check whether the apron is in the public right-of-way, because city spec and inspection change the job. Quoting a new driveway at the same visit? The concrete driveway cost calculator covers the flat part.
