How to Estimate Concrete & Driveway Jobs (2026 Pricing Guide)
Concrete is unforgiving — once it's poured, there's no fixing a bad estimate. Underbid and you eat the cost. Overbid and you lose to the guy who didn't. Here's the math that keeps your margins healthy and your bids competitive.
The Concrete Estimating Formula
Every concrete job has the same cost structure:
Total = Site Prep + Concrete Materials + Labor + Finishing + Overhead & Profit
The trick is getting the volume calculation right. Everything flows from cubic yards of concrete needed.
Step 1: Calculate Concrete Volume
Cubic Yards = (Length × Width × Thickness in feet) ÷ 27
Always add 5-10% for waste, uneven subgrade, and spillage.
Standard thicknesses:
- Sidewalks: 4 inches
- Patios: 4 inches
- Driveways (residential): 4-5 inches
- Driveways (heavy vehicles): 6 inches
- Garage slabs: 4-6 inches
- Foundations: 8-12 inches
Example: 20×40 ft driveway at 5 inches thick
20 × 40 × 0.417 = 333.6 cubic feet ÷ 27 = 12.36 cubic yards
+ 10% waste = 13.6 cubic yards (order 14 yards)
2026 Concrete Pricing Benchmarks
Raw Material Costs
- Ready-mix concrete (3,000 PSI): $140–$180/cubic yard delivered
- High-strength (4,000 PSI): $155–$200/cubic yard
- Fiber-reinforced: Add $8–$15/yard
- Short load fee: $50–$100/yard if ordering under 5 yards
- Saturday/overtime delivery: $150–$300 surcharge
- Pump truck (if needed): $200–$400/hour + $4–$6/yard pumped
- Rebar (#4, ½"): $0.75–$1.25/linear foot
- Wire mesh (6×6 W2.9): $0.15–$0.25/sqft
Installed Pricing (All-In Per Square Foot)
- Basic broom-finish driveway (4"): $8–$14/sqft
- Heavy-duty driveway (5-6"): $10–$18/sqft
- Sidewalk/walkway: $8–$15/sqft
- Patio (broom finish): $8–$14/sqft
- Stamped concrete: $14–$25/sqft
- Exposed aggregate: $12–$22/sqft
- Stained/colored concrete: $10–$18/sqft
- Concrete removal (existing): $2–$6/sqft (includes haul-off)
Step 2: Site Prep Costs
Site prep is where rookies lose money. It's easy to forget:
- Demolition of existing concrete: $2–$6/sqft (jackhammer + haul to dump)
- Excavation & grading: $1.50–$4.00/sqft (depends on depth)
- Compacted base (4-6" gravel): $1.00–$2.50/sqft
- Form boards: $1.50–$3.00/linear foot
- Expansion joints: $1.00–$2.00/linear foot
- Dump fees: $300–$800 per load (old concrete is heavy)
Step 3: Labor Calculation
Concrete labor varies by complexity:
- Basic flatwork (broom finish): 3-person crew pours ~500-800 sqft/day
- Stamped concrete: 4-person crew does ~300-500 sqft/day
- Foundation/structural: Varies wildly — estimate per job
- Labor rate: $40–$70/hour per crew member (concrete is skilled labor)
Real Example: 800 sqft Driveway Replacement
Project: Remove & replace 800 sqft driveway, 5" thick, broom finish
- Demo & Prep
- Remove existing concrete (800 sqft × $3.50): $2,800
- Dumpster + disposal: $650
- Grading & compaction: $1,200
- Gravel base (4"): $1,000
- Form boards (120 LF × $2.50): $300
- Concrete
- Ready-mix: 14 yards × $165 = $2,310
- Wire mesh (800 sqft × $0.20): $160
- Fiber additive: $140
- Expansion joints: $200
- Labor
- Demo crew (1 day, 2 workers): $960
- Pour crew (1 day, 3 workers): $1,440
- Finishing & cleanup: $480
- Subtotal: $11,640
- Overhead & profit (30%): $3,492
- Total: $15,132 ($18.92/sqft)
Decorative Concrete Upsells
Decorative finishes are where margins get fat. The material cost difference between basic and stamped is small — it's mostly labor skill — but clients pay a premium.
- Stamped patterns: Add $6–$12/sqft over basic (most popular: Ashlar slate, random stone)
- Integral color: Add $1–$3/sqft (color mixed into concrete)
- Acid stain: Add $3–$6/sqft (applied after cure)
- Exposed aggregate: Add $4–$8/sqft (surface wash + sealer)
- Sealer: $0.50–$1.50/sqft (should be on every exterior job)
Pro tip: Always offer Good/Better/Best options. A client who came in for a basic driveway will often upgrade to stamped borders or colored concrete when they see the price difference is only $2,000-$3,000 on an $8,000 job.
5 Mistakes That Kill Concrete Estimates
- Underordering concrete. Running short mid-pour means a cold joint, a second truck fee, and a ruined finish. Always round up and add 10% waste factor.
- Ignoring access costs. If the truck can't back up to the pour site, you need a pump truck ($800-$1,500). If wheelbarrows are required, add 50% more labor time.
- Forgetting cure time in scheduling. Concrete needs 7 days before vehicles can drive on it. If there's only one driveway, the client needs alternative parking for a week — set expectations.
- Not checking soil conditions. Expansive clay soil (common in Texas) requires thicker base, possibly piers for structural work. Always ask about soil or dig a test hole.
- Flat-rate quoting without seeing the site. Grade, access, existing conditions, and soil all impact cost ±30%. Never quote concrete from a phone call.
