Concrete Quoting Software: How to Create Accurate Concrete Quotes

An accurate concrete quote is built in a fixed order: define the scope, measure the quantity, price materials from your supplier's current quote, add crew labor at the loaded rate, add equipment and every other direct cost, recover overhead, and only then set the price from a target margin. Concrete quoting software is useful when it keeps those steps separate and visible, so you can see what each number is and where it came from — not when it hides them behind a single "price per square foot."

Two driveways with the same square footage can be very different jobs. Before any number, write down what the quote includes and what it does not:

• Tear-out and haul-off of the existing slab, or new work on a prepared grade.
• Subgrade prep and base: depth and type of compacted gravel.
• Slab thickness, mix and reinforcement (rebar, wire mesh or fiber).
• Forms, expansion joints, control joints or saw cuts, and the finish (broom, stamped, exposed).
• Access: can the truck reach the pour, or do you need a pump or buggies?
• Permits, inspections, and curing or sealing.

A written scope protects your margin. Whatever is not on it becomes a change order, not free work.

Cubic yards = length (ft) × width (ft) × thickness (ft) ÷ 27

Order quantity = cubic yards × (1 + waste %), rounded up to your supplier's increment

Convert thickness from inches to feet first (4 in = 0.333 ft). Choose the waste allowance from your own past pours and this site's conditions; RHACOVA does not assume one. Price the order quantity, because that is what the ready-mix supplier bills. The Driveway Calculator and the general Concrete Calculator handle the geometry, waste and rounding; the Slab and Footing calculators cover other pours.

Concrete is not the only material. Add gravel base, reinforcement (the Rebar Calculator gives bar count and linear feet for a grid), form lumber and stakes, expansion joint material, and curing compound or sealer. Use current quotes from your own suppliers — concrete prices vary by mix, region, season and load size, and RHACOVA does not publish or look them up.

Labor cost = crew hours × loaded labor cost per hour

Estimate crew hours for every phase — tear-out, grading and base, forming, placing and finishing, saw cutting, stripping forms and cleanup — and multiply by the loaded rate, not the wage. The loaded rate includes payroll taxes, workers' comp and benefits; see how to calculate labor burden. If you subcontract a phase such as finishing or saw cutting, carry the sub's quote as its own line instead of hours.

Together with materials and labor, these are the direct cost: every cost the job causes. The full list of cost classes is in what is true job cost.

Overhead recovery = direct cost × your overhead recovery %

Your office, insurance, trucks, phones and software are paid whether or not this driveway is sold. Each quote has to carry a share of them. Calculate your own rate from your annual overhead — see how to calculate construction overhead — and apply it consistently. Recovering overhead only brings the job back to zero; it is not profit.

Total job cost = direct cost + overhead recovery

Price from target margin = total job cost ÷ (1 − target margin)

Margin is profit as a share of price; markup is profit as a share of cost. A 25% markup is only a 20% margin, so quoting "25%" without saying which one underprices the job. See markup vs margin and target margin by type of work. If you round the price or give a discount afterward, recheck the margin — small discounts take a large share of profit.

Every price, rate, hour count and percentage below is illustrative — chosen to show the method, not a current market price, average, productivity rate or recommendation. Replace each with your own numbers.

Scope: remove an existing driveway, then place a new 40 ft × 12 ft × 4 in slab on compacted gravel base with rebar, broom finish and saw-cut control joints.

• 40 ft × 12 ft × 4 in = 160.00 cu ft ÷ 27 = 5.93 cu yd
• 8% waste (example) → 6.40 cu yd, rounded up to the 0.25 increment → 6.5 cu yd ordered

Example inputs: concrete $165.00 per cu yd; 28 crew hours at $55.00 loaded; equipment $350.00 (skid steer, compactor, saw); disposal $450.00; delivery and mobilization $200.00; permit $150.00; other materials $620.00 (gravel base, rebar, forms, expansion joints, curing compound).

• Concrete — order quantity: $1,072.50
• Field labor: $1,540.00
• Equipment: $350.00
• Disposal: $450.00
• Mobilization and delivery: $200.00
• Permits and fees: $150.00
• Other direct cost: $620.00

• Direct cost: $4,382.50
• Overhead recovery (12% of direct cost, example): $525.90
• Total job cost: $4,908.40
• Quoted price at a 25% target margin (example): $6,544.53
• Expected profit: $1,636.13 — margin 25.00%, markup on cost 33.33%

The ready-mix is only a small part of the price. A quote built from yards × a price per yard, or from a square-foot rate copied from last year, would miss tear-out, base, labor, overhead and profit. Run your own driveway in the Concrete Job Bid calculator.

• A clear scope: dimensions, thickness, base, reinforcement, finish and joints.
• Exclusions, such as unsuitable subgrade, irrigation or utility repairs, and sealing.
• The price, payment terms and how long the quote stays valid — ready-mix prices change.
• Assumptions the price depends on, like truck access and weather for the pour.

Keep your internal cost, overhead and margin off the customer document. The customer needs the scope and the price; you need the breakdown.

• Quantities calculated from dimensions, with waste and order rounding you control.
• Your own prices and rates, not hidden averages.
• Labor, equipment, overhead and profit as separate lines, not one blended number.
• Pricing from a target margin, with a warning when a quote drops below your minimum.
• A path from the accepted quote to tracking what the job actually costs.

RHACOVA works this way. The free Concrete Job Bid calculator turns your quantity and costs into a price. With an account, you can continue that bid into a RHACOVA Estimate, where Profit Guard flags a price below your minimum margin before it reaches the customer, then send the proposal and track actual job costs against it. See concrete estimating software, contractor estimating software and plans and pricing. For the cost side in more depth, read how to estimate concrete cost.

• Quoting from a price per square foot without checking this job's scope.
• Leaving out tear-out, haul-off, base or reinforcement.
• Pricing the geometric volume instead of the quantity you order.
• Pricing labor at the wage instead of the loaded rate.
• Forgetting short-load, pump or truck wait-time charges.
• Skipping overhead recovery, or treating it as profit.
• Applying a margin percentage as a markup.
• Sending a quote with no exclusions and no expiration date.
