How to Estimate Concrete Jobs: Complete Pricing Guide
Estimate concrete jobs by calculating cubic yardage (length x width x thickness / 27), adding 10% waste, then pricing ready-mix at $130-$170 per yard delivered. Add rebar at $0.75-$1.50 per sq ft, forms at $1-$2 per sq ft, and labor at $45-$85 per hour. Most residential concrete jobs range from $3,000-$18,000, with driveways averaging $6-$12 per sq ft and patios $8-$15 per sq ft.
Pricing concrete jobs correctly is the difference between building a profitable contracting business and working yourself into the ground. Charge too little and you burn through margins even on busy weeks. Charge too much and your close rate craters. This guide breaks down the exact formula successful concrete contractors use to price every type of job — from simple sidewalks to complex foundation work — so you can bid with confidence and protect your margins.
The Concrete Pricing Formula
Every concrete job should be priced using this formula: Materials + Labor + Equipment + Overhead + Profit = Bid Price. Start with material costs: calculate cubic yardage (length x width x thickness in feet, divided by 27), add 10% for waste, and price ready-mix at $130-$170 per yard delivered depending on PSI strength and your market. Rebar runs $0.75-$1.50 per sq ft of slab area, wire mesh $0.40-$0.70 per sq ft, and form lumber $1-$2 per sq ft. Labor should be calculated at your fully burdened rate — not just crew pay, but including payroll taxes, workers comp, and benefits. For most markets in 2026, that means $45-$85 per hour depending on skill level. Equipment costs include concrete vibrators, finishing tools, power trowels, and saw-cutting equipment. Add 15-25% for overhead (insurance, truck payments, office costs) and 10-20% for net profit. Many concrete contractors skip the overhead step, which is why the industry average net margin hovers around 6-10% instead of the 15-22% that well-run companies achieve.
Calculating Concrete Yardage Accurately
Accurate yardage calculation is the foundation of every concrete estimate. The formula is simple: Length (ft) x Width (ft) x Thickness (ft) / 27 = Cubic Yards. For a 20 ft x 30 ft driveway at 4 inches thick: 20 x 30 x 0.333 / 27 = 7.4 cubic yards. Always add 10% for waste, subgrade irregularities, and form bulging — so order 8.2 yards. Ready-mix trucks typically carry 8-10 yards, so you would order a full truck. For irregular shapes, break the area into rectangles and triangles, calculate each separately, and sum them. For sloped pours, calculate the average thickness. Short loads (under 8 yards from many plants) carry a $50-$100 surcharge per yard under minimum. If your calculation comes to 6 yards, consider whether adding a small extension or thickening the slab makes sense to hit the 8-yard minimum and avoid the surcharge. Saturday and overtime delivery fees add $50-$150 per load. Factor these into your estimate when the project schedule demands weekend pours.
Setting Your Labor Rate for Concrete Work
Your labor rate is the single biggest factor in profitability. A three-person concrete crew earning $20-$30/hour costs you $75-$110/hour when you add payroll taxes (7.65%), workers compensation (10-18% for concrete — higher than most trades), general liability insurance allocation, vehicle costs, and small tools. Most concrete contractors charge $50-$75 per man-hour for general flatwork and $70-$100 for skilled finishing work like stamping, exposed aggregate, or decorative overlays. In high-cost markets (Northeast, West Coast, Denver), rates run 15-25% higher. To find your number, calculate your total annual overhead, divide by your billable hours (typically 1,200-1,500 per crew member per year after weather days, cure time between jobs, and holidays), and add that per-hour overhead to your direct labor cost. Concrete work has more weather downtime than most trades — don't ignore this when calculating your annual billable hours. This gives you a break-even rate, then add your profit margin on top.
Pricing by Concrete Job Type
Different concrete services have different margin profiles. Driveways are the bread-and-butter job, priced at $6-$12 per sq ft for standard broom finish with wire mesh reinforcement. Patios command higher rates at $8-$15 per sq ft, and $15-$25 per sq ft for stamped or decorative finishes. Sidewalks run $6-$10 per sq ft. Foundation work — footers, stem walls, and slabs — prices at $8-$15 per sq ft depending on structural requirements. Retaining walls cost $20-$40 per face sq ft including footer, rebar, and forming. Demolition and removal of existing concrete runs $2-$6 per sq ft depending on thickness and rebar. Steps price at $200-$500 per step depending on width and complexity. The highest-margin concrete work is typically decorative — stamped concrete, exposed aggregate, and acid staining — where your expertise in finishing technique justifies premium pricing of $15-$30 per sq ft.
Material Markup Strategy for Concrete
Material markup covers more than just the concrete and rebar. You spend time coordinating deliveries, scheduling pumps, picking up forms and supplies, and managing waste. Standard markups in concrete work run 15-30%: 15-20% on ready-mix concrete where the client can easily price-check per-yard costs, 20-25% on rebar, wire mesh, and form materials, and 25-30% on specialty items like sealers, curing compounds, stamping mats, and color hardener. Never show your wholesale cost on proposals — present the marked-up price as your material price. For large pours requiring 20+ yards, negotiate volume discounts with your ready-mix supplier (often $5-$15 per yard off list) and retain the savings as additional margin. Concrete pump costs ($150-$250 per hour with a typical 4-hour minimum) should be passed through at cost or with a small markup — pumping is a visible, verifiable expense that clients accept.
Common Pricing Mistakes to Avoid
The most expensive mistake concrete contractors make is underestimating site preparation and access difficulty. Jobs requiring wheelbarrow placement instead of direct chute pour can double your labor hours. Always assess access during your site visit and price accordingly — pump truck costs or extended crew time for manual placement must be in the bid. Second, many contractors forget to price cure time between jobs. Concrete requires 24-48 hours before forms can be stripped and 7 days before heavy loads — this downtime must be recovered in your pricing. Third, stop pricing from memory. Ready-mix costs change quarterly, rebar prices fluctuate with steel markets, and lumber for forms follows its own cycle. Use real-time pricing tools to eliminate this guesswork. Fourth, always account for finishing complexity. A broom finish takes 30 minutes per 100 sq ft; a stamped finish takes 2-3 hours per 100 sq ft. Finally, never give verbal quotes — every estimate should be a written proposal with scope, materials, specifications, timeline, and payment terms.
