Concrete Curb and Gutter Cost per Linear Foot
Estimate concrete curb and gutter cost per linear foot by separating ready-mix material, forms, excavation, reinforcement, drainage, access, permits, and contractor quote scope.
Concrete curb and gutter cost per linear foot is a quote comparison number, not just a volume formula. A material-only estimate uses linear feet, curb profile, gutter width, concrete volume, waste, and delivery fees. An installed quote can also include excavation, forms, base prep, reinforcement, drainage tie-ins, driveway apron transitions, permits, traffic control, access, cleanup, and labor.
Competitor tools such as ConcreteCalculator.pro's curb and gutter calculator and ConcreteCalculatorMax's curb and gutter calculator are useful for quantity checks. This guide turns that quantity into a bid review workflow so the linear-foot number can be compared against the written scope.
If the curb work connects to a driveway, also review the Concrete Driveway Apron Cost Guide. For sidewalk work nearby, use the Concrete Sidewalk Cost Calculator Guide. For bid normalization, use the Concrete Quote Reviewer.
Quick answer
Calculate two curb and gutter numbers:
material cost per linear ft =
ready-mix material, delivery, tax, and fees
/ total curb and gutter linear feet
installed quote per linear ft =
contractor quote total
/ total curb and gutter linear feet
For a simple planning check, a 100 ft run with a 6 in by 6 in curb and an 18 in by 6 in gutter has about 1.00 sq ft of rectangular cross-section. That is about 3.70 yd3 before waste, or 4.07 yd3 with 10% waste. At $165 per yd3 plus a $150 delivery or short-load fee, the material-only check is about $821.55, or $8.22 per linear ft.
If the installed quote is $6,500:
$6,500 / 100 ft = $65.00 per linear ft installed
Those two numbers are not supposed to match. The installed quote may include layout, excavation, forming, placement, finish, saw cuts, drainage, permits, traffic protection, cleanup, and contractor overhead.
Curb and gutter inputs to separate
Do not compare curb and gutter bids until each quote uses the same profile, linear feet, and site scope.
| Input | Material-only estimate | Installed quote check |
|---|---|---|
| Linear feet | Divides material cost by run length. | Sets layout, forms, and labor length. |
| Curb height and width | Controls curb concrete volume. | Changes forms, finish, and transitions. |
| Gutter width and thickness | Controls gutter volume. | Changes drainage and road/driveway tie-in scope. |
| Waste factor | Adds order cushion. | Should reflect profile complexity and formwork. |
| Excavation | Usually excluded. | May include saw cutting, removal, grading, and haul-off. |
| Forms | Not part of ready-mix. | Often a major labor line for curb profiles. |
| Reinforcement or dowels | Not in concrete yards. | Should be specified if included. |
| Drainage and slope | Not volume math. | Can drive grading, inlets, transitions, and inspections. |
| Permits or right-of-way | Not material cost. | Can affect timeline, traffic control, and liability. |
For driveway-related scope, compare the Concrete Driveway Calculator Guide and the Concrete Driveway Extension Cost Guide.
Formula for curb and gutter material cost
For a simple rectangular planning profile:
curb cross-section sq ft =
curb width in x curb height in / 144
gutter cross-section sq ft =
gutter width in x gutter thickness in / 144
total cross-section sq ft =
curb cross-section sq ft + gutter cross-section sq ft
Then estimate concrete:
cubic yards =
linear feet x total cross-section sq ft / 27
Add waste and pricing:
order quantity = cubic yards x (1 + waste percentage)
ready-mix material =
order quantity x price per yd3
+ delivery, short-load, fuel, tax, and access fees
Real curb and gutter profiles are often not perfect rectangles. Use this as a planning check, then ask the contractor or supplier which profile, dimensions, and waste factor are included.
Example: 100 ft curb and gutter run
Assume:
- Run length: 100 ft
- Curb: 6 in wide by 6 in high
- Gutter: 18 in wide by 6 in thick
- Waste: 10%
- Ready-mix: $165 per yd3
- Delivery or short-load fee: $150
Cross-section:
6 x 6 / 144 = 0.25 sq ft curb
18 x 6 / 144 = 0.75 sq ft gutter
0.25 + 0.75 = 1.00 sq ft total
Concrete quantity:
100 x 1.00 / 27 = 3.70 yd3 before waste
3.70 x 1.10 = 4.07 yd3 after waste
Material check:
4.07 x $165 = $671.55
$671.55 + $150 = $821.55
$821.55 / 100 ft = $8.22 per linear ft material-only
If the installed quote is $6,500:
$6,500 / 100 ft = $65.00 per linear ft installed
Ask what is included in the difference: excavation, forms, reinforcement, finish, transitions, cleanup, permits, and access.
What changes curb and gutter cost
| Cost driver | Why it changes the quote |
|---|---|
| Profile shape | Rolled curb, vertical curb, and curb-gutter profiles use different forms. |
| Removal | Existing curb, asphalt, or concrete may need saw cutting and haul-off. |
| Drainage | Gutter slope, inlets, and low spots can change layout and inspection. |
| Driveway apron tie-in | Aprons, flares, and sidewalks need clean transitions. |
| Forms and finish | Curbs often need more form and edge work than flat slabs. |
| Access and traffic | Street-side work can require staging, cones, or traffic control. |
| Permits | Right-of-way work may need local approval and inspection. |
| Small load | Short runs can carry high delivery or minimum-load fees. |

Curb and gutter quote red flags
| Red flag | What to ask |
|---|---|
| No profile dimensions | What curb height, curb width, gutter width, and gutter thickness are included? |
| Linear feet only | Are end returns, driveway transitions, and radii included? |
| Removal vague | Does the price include saw cutting, breaking, loading, haul-off, and disposal? |
| Drainage not mentioned | How is slope handled and what happens at low points or inlets? |
| Permit responsibility unclear | Who handles right-of-way approval, inspection, and traffic control? |
| Formwork hidden | Are forms, stakes, stripping, and cleanup included? |
| No access plan | Can ready-mix reach the run, or is buggy/wheelbarrow placement needed? |
| Cleanup missing | Who handles washout, debris, street cleanup, and site protection? |
Use the Concrete Quote Reviewer if two bids have different profiles or unclear removal and permit scope.

FAQ
How do I calculate concrete curb and gutter cost per linear foot?
Divide the total quote by the curb and gutter linear feet. For a material-only check, estimate the curb and gutter cross-section, convert it to cubic yards, add waste and delivery fees, then divide by linear feet.
Why is installed curb and gutter cost higher than concrete material cost?
Installed cost can include removal, excavation, forms, finish labor, drainage tie-ins, permits, traffic control, access equipment, cleanup, warranty, and contractor overhead.
Is curb and gutter priced by linear foot or cubic yard?
Use both. Cubic yards check the concrete quantity. Linear feet check the installed quote and helps compare contractors using the same profile.
Does driveway apron work change curb and gutter cost?
Yes. Apron transitions, curb cuts, flares, sidewalk tie-ins, permits, and drainage can change the scope even if the linear feet look similar.
Should removal be included in curb and gutter pricing?
Only if the quote says so. Old curb, gutter, asphalt, or concrete removal should be listed as a separate line or clearly included in the written scope.
Can I use a curb and gutter calculator as a final quote?
No. A calculator gives material volume. Final pricing depends on site conditions, forms, removal, access, permits, local rules, and labor.
Next step
Use the formula above for a material check, then review the written scope with the Concrete Quote Reviewer. For curb and gutter, the useful number is not just cost per linear foot. It is cost per linear foot for the same profile and scope.
