Step 1: Convert concrete volume to yd³ if needed
Step 2: Concrete material cost = Volume (yd³) × Price per yd³
Step 3: Labor cost = Total crew hours × Labor rate per hour
(1 man-day = 8 hours if man-days selected)
Step 4: Direct cost subtotal = Concrete + Short load fee + Sales tax on materials + Rebar + Forming + Other materials + Labor + Equipment + Subcontractor + Permits + Demo
Step 5: Markup amount = Subtotal × (Markup% ÷ 100)
Step 6: Total bid = Subtotal + Markup amount
Step 7: Gross profit = Total bid − Subtotal
Step 8: Gross margin % = (Gross profit ÷ Total bid) × 100

Note: Markup % and gross margin % are NOT the same number.
A 25% markup on $10,000 = $12,500 bid → 20% gross margin.

How to Use This Concrete Bid Generator

Calculate your concrete volume first. Before you touch this tool, use the Concrete Slab Calculator or the appropriate shape calculator to get your cubic yards with waste factor already applied. Enter that volume in the Concrete Volume field — it's the single most important input and any error here flows through every line of your bid.
Get a current plant quote, then fill in costs. Call your ready-mix supplier and get today's price per yard for the PSI and mix design your job requires. Prices vary by region and change seasonally — never guess from a previous job. Enter your actual all-in labor rate (wages + burden), not just the hourly wage you pay on the check. Skipping burden is the number one reason concrete contractors underbid.
Set your markup, not your margin. The markup field here is applied to your direct costs — it is not the same as gross margin percentage. A 25% markup on $10,000 in costs gives you a $12,500 bid and a 20% gross margin. If you want a specific margin target, work backwards: markup % = margin % ÷ (1 − margin %). For a 25% margin, you need a 33.3% markup.
Copy the generated proposal text and customize it. The output below the cost breakdown is a formatted proposal starter. Paste it into your company letterhead template, add your license number, payment terms, and scope exclusions before sending. Never send an unsigned, unformatted bid text directly — it looks amateurish and undermines your credibility before the job starts.

⚠ Pro Tip: Your labor burden (payroll taxes, workers' comp, liability insurance, benefits, truck costs) typically adds 35–50% on top of wages. If you pay a finisher $28/hr, your actual all-in cost is closer to $40–$42/hr. Bidding at $28/hr and wondering why you're losing money every month isn't a mystery — it's math. Run your burden rate before you fill in a single field here.

How Concrete Bid Pricing Is Calculated

A properly structured concrete bid has three layers: direct costs (everything you spend to complete the job), markup (your overhead recovery and profit), and the final bid price. Here's the exact calculation sequence:

Step	Formula	Example (5 yd³ driveway)
1. Concrete material cost	Volume (yd³) × $/yd³	5 yd³ × $140 = $700
2. Labor cost	Total hours × $/hr (all-in rate)	16 hrs × $55 = $880
3. Equipment & other	Sum of all other line items	$150 pump + $100 forms = $250
4. Direct cost subtotal	Concrete + Labor + Other	$700 + $880 + $250 = $1,830
5. Markup amount	Subtotal × (markup% ÷ 100)	$1,830 × 0.25 = $457.50
6. Total bid price	Subtotal + Markup	$1,830 + $457.50 = $2,287.50
7. Gross margin %	(Profit ÷ Bid total) × 100	($457.50 ÷ $2,287.50) × 100 = 20%

Project Type	Typical Size	Direct Cost	Bid Total (25% markup)	$/sq ft (installed)
Small patio slab	10×10 ft, 4 in	$680–$850	$850–$1,065	$8.50–$10.65
Standard patio	20×20 ft, 4 in	$2,400–$3,100	$3,000–$3,875	$7.50–$9.70
2-car driveway	20×22 ft, 6 in	$3,800–$4,900	$4,750–$6,125	$10.80–$13.90
2-car garage floor	24×24 ft, 6 in	$4,600–$6,000	$5,750–$7,500	$9.98–$13.02
Shed / equipment pad	12×12 ft, 4 in	$950–$1,250	$1,190–$1,565	$8.25–$10.87
Sidewalk (100 lin ft, 4 ft wide)	400 sq ft, 4 in	$2,100–$2,700	$2,625–$3,375	$6.56–$8.44
RV pad	12×40 ft, 6 in	$5,200–$6,800	$6,500–$8,500	$13.54–$17.71

Prices based on US national averages for 2024–2025. High-cost metro areas (CA, NY, MA) may be 40–70% higher. Rural Midwest may be 15–25% lower. Always quote from your actual costs, not this table.

What Markup Percentage Should You Use?

Markup is the most misunderstood number in contractor estimating. There is no single "right" answer — the correct markup for your business depends on your overhead rate, your target net profit, and your market position. The table below shows what different markup levels actually deliver.

How markup percentage translates to gross margin and what it covers in a typical concrete contractor's overhead structure.
Markup %	Gross Margin %	Typical Use Case	Risk Level
10%	9.1%	Highly competitive commodity bids; large volume GC subwork	High — leaves almost no room for errors or rework
15%	13.0%	High-competition markets; low overhead operations	Moderate-high — tight but workable for lean shops
20%	16.7%	Standard subcontract work; established recurring clients	Moderate — most mid-size contractors' floor
25%	20.0%	Typical residential contractor; new client acquisition	Low-moderate — healthy margin for most operations
33%	24.8%	Specialty work; complex or hazardous scopes; tight schedule	Low — appropriate for higher-risk or premium projects
50%	33.3%	Emergency work; small urgent repairs; no competitive pressure	Very low — justified when demand exceeds capacity

To find your minimum viable markup, add up your annual overhead (insurance, office, trucks, fuel, tools, admin) and divide by your annual direct costs. That percentage is your breakeven markup — anything below it means you're losing money on every job, just slowly enough not to notice until year three.

Common Mistakes When Bidding Concrete Work

⚠️
Confusing markup with gross margin. Contractors lose money on this one daily. A 20% markup is not a 20% profit margin — it's a 16.7% gross margin. If your overhead runs 14% of revenue, a 20% markup leaves you 2.7% net margin before any surprises. Know the difference before you set a single number.
📋
Bidding the labor cost, not the labor burden. Paying a worker $30/hr and billing $30/hr is a guaranteed loss. Payroll taxes (FICA, FUTA, SUTA) add roughly 10–12%. Workers' comp for concrete work runs 15–25% of payroll in most states. Add general liability insurance allocation, vehicle costs, and benefits, and your burden rate is commonly 40–55% over base wages. If you're not including burden in your labor rate, you are subsidizing your clients' work out of your own pocket.
📐
Forgetting the short load fee on small pours. Most ready-mix plants charge a short load surcharge — typically $75–$200 — when you order less than a full truck (usually 7–9 yd³). On a small 2 yd³ job, that fee can represent 10–15% of your concrete cost alone. It should always be its own line item so clients see it clearly, and so you don't eat it.
🔩
Estimating forming labor from past jobs without adjusting for site conditions. A 20×20 ft flat square garage slab takes a fraction of the forming time compared to a curved driveway with multiple step-downs and expansion joints on a sloped lot. Using a flat "hours per square foot" from your easiest job to price your hardest job is how you end up working for free on the complicated ones.
📄
Sending a bid with no scope of work, exclusions, or payment terms. A number on a piece of paper is not a bid — it's an invitation for disputes. Every proposal should clearly state what is included (forming, pour, broom finish, one application of curing compound), what is explicitly excluded (gravel base, permits, rebar unless listed), and payment terms (50% deposit, balance due upon completion). Without this, clients assume everything is included and you have no leverage when they ask for extras.

Frequently Asked Questions

Markup is calculated on cost. Margin is calculated on revenue. A 25% markup on $10,000 in direct costs gives you a $12,500 bid — and a 20% gross margin, not 25%. The formula: margin % = markup % ÷ (1 + markup%). Conversely, if you want a target margin of 25%, the markup you need is: markup % = margin % ÷ (1 − margin%) = 25% ÷ 75% = 33.3%. Confusing these two numbers is one of the most common reasons small contractors don't survive their third year.
For residential concrete work in the US, most contractors apply 20–35% markup over direct costs, with 25% being the most common starting point. Specialty or complex work (decorative finishes, structural slabs, tight access sites) may justify 30–40%. Subcontract work for general contractors typically runs lower — 15–20% — because GCs often expect a discount for volume or guaranteed workflow. The right markup for your business is not what competitors charge; it's your total annual overhead divided by your annual direct costs, plus your target net profit percentage.
A professional concrete proposal should include: your company name, license number, and contact information; the client's name and project address; a clear scope of work (dimensions, thickness, mix design, finish type); an explicit list of exclusions (what is not included); the total bid price with a line-item breakdown if requested; payment terms (deposit amount, milestones, and final payment due); validity period for the quote (typically 30 days given material price volatility); warranty information if applicable; and a signature line for client acceptance. Proposals without exclusions invite scope creep. Proposals without payment terms invite slow payment.
Start with the base hourly wage. Add the payroll tax burden: FICA (7.65%), FUTA (0.6% on first $7k), SUTA (varies by state, typically 2–5%). Add workers' compensation insurance — concrete flatwork (class code 5506 in most states) commonly runs 15–25% of payroll depending on your experience modifier. Add general liability insurance allocation per labor hour. Add any benefits (health, retirement). A worker earning $30/hr frequently has an all-in cost of $42–$47/hr once burden is calculated correctly. Use $30/hr in your bid and you're losing $12–$17/hr in hidden costs.
This depends heavily on crew size, site conditions, finish type, and whether a pump truck is used. Rough benchmarks for a 3-person crew: a standard 400–600 sq ft patio at 4 inches (1.5–2 yd³) typically runs 6–10 total man-hours for pour day alone. A 2-car garage floor (576 sq ft, 6 in, ~3.5 yd³) typically runs 18–28 man-hours total including forming, pour, and finishing. A 20×20 ft driveway (24 man-hours is common). Add forming and prep time separately — it's often as much as the pour day itself for complex jobs. Do not estimate from square footage alone; site complexity, access constraints, and finish requirements dominate the actual hours.
For most residential clients, a lump-sum bid with a clear scope of work is the professional standard — and often the smarter business choice. Showing every line item invites clients to negotiate individual pieces ("Can we cut the rebar?") and opens up your cost structure for competitors to undercut. However, for commercial work, government contracts, or clients who specifically request transparency, an itemized bid is often required or builds trust. When you do itemize, group costs logically (materials, labor, equipment, overhead, markup) rather than exposing your exact cost on every nut and bolt.
Most concrete contractors specify a 30-day validity period on bids. Ready-mix prices fluctuate — sometimes significantly — with fuel costs, cement shortages, and seasonal demand. A bid that was profitable in March can be a money-loser in June if you locked in a price without a validity clause and the concrete plant raised its rate. For large commercial projects or in highly volatile markets, some contractors shorten the validity to 15 days. Always include the validity language explicitly: "This proposal is valid for 30 days from the date above."
For residential concrete work, a 30–50% deposit upon contract signing is standard practice and reasonable. The deposit covers your concrete order (which must typically be paid at delivery or within 30 days), your forming materials, and crew scheduling costs. Never mobilize for a concrete job without a signed contract and deposit — concrete cannot be reversed once poured, and you have no leverage if a client refuses to pay after the fact. For large commercial jobs, a draw schedule tied to milestones (mobilization, pour, completion) is more appropriate than a single large deposit.
A short load fee (also called a minimum delivery charge or short load surcharge) is charged by ready-mix plants when you order less than their minimum truck capacity — typically 7–9 cubic yards depending on the plant and truck size. The fee compensates the plant and driver for the overhead of a partially loaded truck run. It typically ranges from $75 to $250 depending on the region and plant. For small jobs under 3–4 yd³, the short load fee can be a significant percentage of your concrete cost. Always ask your plant for their current minimum order and short load fee before bidding a small pour.
Whether you pull the permit or the client does depends on your contract and local practice. If your company pulls the permit, the fee should always appear as a line item in your bid — never absorb it silently, because permit fees vary widely ($50 to several hundred dollars) and inspections affect your schedule. If the client is responsible for pulling their own permit, state that explicitly as an exclusion. Either way, make the arrangement unambiguous in writing before the job starts. A job stopped by an inspector because no permit was pulled — and you each thought the other was handling it — is an expensive lesson.
