Sidewalk estimating note
Sidewalk cost depends on more than concrete volume. Length, width, thickness, base depth, form boards, excavation, finishing, and access can all change the final installed price.
Common sidewalk thickness
4 inches
Driveway crossings or heavier loads may need thicker concrete.
Calculate concrete sidewalk cost
Enter sidewalk dimensions, thickness, base depth, form cost, labor, finishing, delivery, and waste to estimate total sidewalk project cost.
Sidewalk estimate
Estimated total
$2,197
About $55 per linear foot.
This is a planning estimate. Final sidewalk pricing depends on demolition, excavation, grading, soil, drainage, reinforcement, forms, finish quality, access, local labor, material pricing, and code requirements.
For homeowners
Use the estimate to plan a new sidewalk, walkway, garden path, or replacement section before getting contractor quotes.
For contractors
Quickly estimate sidewalk yards, form length, base material, labor, delivery, finishing, and total project cost.
For property managers
Use the calculator to compare sidewalk repair or replacement scopes across rentals, commercial properties, and managed sites.
Concrete sidewalk calculator FAQs
How thick should a concrete sidewalk be?
Many residential sidewalks are 4 inches thick for foot traffic. Sidewalks that cross driveways or support heavier loads may need thicker concrete.
How do I calculate concrete for a sidewalk?
Multiply length by width by thickness in feet to get cubic feet. Divide by 27 to convert to cubic yards, then add waste.
How much form board do I need for a sidewalk?
For a straight sidewalk, estimate form board length as both sides of the sidewalk, or length multiplied by two. Add extra for cuts, stakes, curves, and waste.
Does this include demolition?
No. This calculator focuses on new sidewalk material and installation assumptions. Add demolition, haul-off, permits, or special access separately.
