General contractors get paid through a mix of base fees, markups on labor and materials, and percentage charges built into the total project cost. Most use staged payments tied to project milestones, starting with a deposit and ending with a final payout after sign-off.
The exact fee structure depends on contract type, project size, and how the bid is built.
Key Takeaways
- General contractors charge between 10% and 30% of total project cost depending on project size, with small jobs running 10–15% and large or custom builds reaching 20–30%.
- The fee a homeowner sees on the bid is not the same as the contractor's profit margin – GCs also build margin through general conditions markups, sub buyout savings, self-perform work, and change order revenue.
- Labor and material markups are separate from the base fee: labor typically carries a 20–50% markup and materials run 10–30%, with specialty trades and custom orders pushing both toward the higher end.
- Most contractors structure payments in stages tied to project milestones, starting with a 10–20% deposit at signing and ending with a 5–10% final payment held until punch list completion and sign-off.
- Homeowners can protect themselves at every payment stage by requesting lien waivers from subcontractors and negotiating retainage of 5–10% on each progress payment until the job is fully complete.
Contractor Pricing Models & Fee Structures
A major part of a general contractor’s job is to figure out how much to charge. This often takes time, skill, and experience, the same foundation required to become a licensed general contractor in the first place.
Learning how contractors price their work helps you compare bids and set expectations. Each pricing model affects the total project cost and how the contractor earns.
Common pricing models (hourly, fixed, percentage)
Contractors usually work with three pricing models: hourly rate, fixed price, and percentage of project cost.
| Pricing Model | How It Works | When It Fits | What to Watch For |
|---|---|---|---|
| Hourly Rate | You pay for each hour worked, plus materials at cost. | Small repairs or open-ended jobs where scope may shift. | No ceiling on total cost if hours run long. |
| Fixed Price | One total price agreed upfront for the full scope. | Defined projects with complete plans and specs. | Change orders carry their own markup once work starts. |
| Percentage of Project Cost | Contractor charges a set percentage of total job cost. | Larger renovations or builds with many subs. | The percentage covers overhead and profit, not just profit. |
| Cost Plus | You pay actual costs plus a fixed fee or set percentage. | Custom builds where exact scope can't be priced upfront. | Ask for itemized backup on every invoice. |
How general contractors estimate jobs is key to setting fair pricing. The best way to do this is by giving clients a detailed cost estimate that outlines expected labor and material costs, overhead, and profit. Sharing a clear general contractor price sheet early builds trust, avoids confusion, and can lead to repeat work.
For example, in a cost-plus contract, clients pay the actual job costs plus a fixed fee. Adding this option to your price sheet can simplify conversations and help move projects forward quickly.
When preparing your estimate, don’t forget these common costs:
- Local tax laws and building regulations
- State and industry payment standards
- Credit terms and agreements
- Insurance and liability coverage
- Warranty periods
- Change orders and extra work
- Retainage of subcontractors
Typical fees by home size and project type
How much should a general contractor charge? It depends on the project size:
| Project Size | Typical Fee Range | What This Covers |
|---|---|---|
| Small Job | 10% – 15% | Single-room work, minor remodels, light renovations. |
| Mid-Size Job | 15% – 20% | Full kitchen or bath remodels, multi-room renovations. |
| Large or Custom Job | 20% – 30% | Whole-home remodels, additions, custom builds. |
Contractors typically charge 10% to 30% of the total cost. Bigger or more complex jobs may cost more.
Fees cover overhead costs, managing subcontractors, labor, materials, and scheduling. A2Z Construction lists all general contractor fees clearly and adapts pricing to each project.

Markups, Margins & Profit Potential
Beyond base fees, contractors build profit through strategic markups and project efficiency. Understanding these components helps homeowners interpret bids accurately.
Standard markup ranges on labor and materials
Markup is how general contractors make money beyond base labor cost. Most contractors charge a markup on both labor and materials to cover expenses and generate profit.
- Labor markup: 20%–50% depending on project complexity, labor availability, and region.
- Material markup: 10%–30%, factoring in transportation, sourcing time, and quality control.
This covers overhead and profit while accounting for risk. Markups vary depending on project size, material costs, and subcontractor rates. Markup is also used to buffer unexpected costs that may arise during the project.
Profit margins by project size
Profit margin is what stays with the contractor after paying labor, materials, subcontractors, insurance, permits, and overhead. It's not the same as the fee charged on top of the project cost.
These typically fall between 10% and 20%, but they vary widely:
| Project Type | Profit Margin Range | Why |
|---|---|---|
| Small Project | 10% – 15% | Lower coordination cost, but limited room to absorb surprises. |
| Mid-Size Residential | 15% – 25% | More trades to manage, more risk, more room to find efficiencies. |
| High-End or Complex Build | 25% – 35% | Long timelines, custom work, and design risk justify higher margin. |
These margins must cover not just labor and material, but also insurance, equipment, permits, and administrative support. Contractors managing multiple trades and schedules need higher profit margins to absorb coordination costs.
Understanding these margins helps clients assess bids realistically. For A2Z Construction, maintaining clear markup practices helps clients know where their money is going and promotes long-term trust.
How General Contractors Build Margin Beyond the Stated Fee
The fee a contractor charges is only one part of how the project actually pays. Experienced GCs build additional margin through general conditions, self-perform work, sub buyout, and schedule efficiency. None of this is hidden, but most homeowners never see it broken out.
General Conditions Markup
General conditions cover the costs of running the job site: project manager and superintendent salaries, site office, dumpsters, fencing, temporary power, and insurance. GCs bill these costs at a rate above their actual cost.
A superintendent paid $84 per hour, fully loaded, may be billed to the project at $120 per hour. See how contractor salaries compare to what gets billed. Insurance and bond rates often carry a similar markup.
Sub Buyout
When a GC bids the job, they use sub quotes to build the total. After the contract is signed, they often negotiate those sub-quotes lower. The savings stay with the GC. On a year-long mid-size project, sub buyout commonly produces 1 to 3 percent of total contract value in additional margin.
Self-Perform Work
When a GC performs work in-house instead of subbing it out, they keep both the trade-level profit and their own GC fee on top. Concrete, framing, and demo are the most common self-perform packages.
Schedule Acceleration
Every week saved on the schedule is a week of general conditions the GC doesn't pay out. Finishing a 12-month job in 11 months saves a full month of trailer rent, supervision, insurance, and overhead. Those savings drop to the bottom line.
Change Order Markup
Change orders carry a contractually agreed markup, typically 10 to 20 percent over the cost of the added work. Frequent change orders on a job add up to a meaningful revenue stream beyond the original contract value.
How General Contractors Make Money in the US
Across the US, general contractor income comes from base fees, markups, change order revenue, and the margin sources covered above. Vendor relationships, repeat sub crews, and bulk material purchasing let experienced contractors hold their costs lower than what they bill on the project.
Payment Terms & Cash Flow Management
Managing cash flow is essential for project continuity. Contractors often structure payments to ensure adequate resources at each stage of the job.
Payment schedules and billing stages
How do general contractors get paid? Most use staged payments tied to project milestones:
| Stage | % of Total | When It's Paid | Purpose |
|---|---|---|---|
| Initial Deposit | 10% – 20% | At contract signing. | Confirms agreement, locks scheduling, funds initial materials. |
| Progress Payment 1 | 20% – 30% | After demo and framing. | Covers structural work and rough carpentry. |
| Progress Payment 2 | 20% – 30% | After mechanicals and drywall. | Covers MEP rough-in, insulation, and drywall completion. |
| Progress Payment 3 | 15% – 25% | After finishes are installed. | Covers cabinetry, flooring, paint, and fixtures. |
| Final Payment | 5% – 10% | After punch list and inspections. | Released once walk-through and sign-off are complete. |
| Total | 100% of contract value | ||
This method helps contractors manage cash flow while aligning with project progress. It also gives homeowners visibility and control over how their funds are used.
Deposits, retainers, and final payouts
- Deposits secure the job and allow contractors to purchase materials upfront.
- Retainers are sometimes required for high-demand contractors or to book specific timeframes.
- Final payouts are contingent on walk-throughs, inspections, and punch list completion.
A2Z Construction provides detailed payment breakdowns before work begins and sticks to predefined billing stages.
Managing change orders and scope creep
Change orders are a common income stream and risk factor. They occur when clients request additions or alterations mid-project. Contractors typically charge:
- Time and materials plus markup
- Flat fees for known additions or revised drawings
Proper documentation, signed approvals, and real-time communication help reduce disputes. Detailed initial scoping, along with strong project management, reduces scope creep and keeps the total cost on track.
Lien Waivers and Payment Protection for Homeowners
When a homeowner pays a general contractor, that money is supposed to flow to subs and suppliers. If it doesn't, those subs can file a mechanic's lien against the property, even though the homeowner already paid.
A lien waiver is a signed document from each sub or supplier stating they've been paid for work to date. Homeowners should ask for conditional and unconditional lien waivers at every progress payment.
Retainage also protects the homeowner. This is a percentage of each progress payment, usually 5 to 10 percent, held back until the project is complete and signed off. It gives the contractor a financial reason to finish punch list items and resolve any defects before final payout.
What Efficient Contractors Do Differently
When you're comparing bids, price alone doesn't tell the full story. A contractor who runs tight schedules, uses established sub crews, and buys materials in volume can often deliver better work at a similar price point than a lower bidder who makes up the difference through change orders or slow progress payments.
Look for these in a bid:
- Itemized general conditions – A detailed breakdown of site supervision, insurance, and overhead costs signals that the contractor tracks these numbers closely.
- Named subcontractors – GCs with established trade relationships tend to have more predictable labor costs and fewer mid-project surprises.
- Clear change order terms – The markup rate on change orders should be stated in the contract before work starts, not negotiated after you've already approved the scope change.
- A defined payment schedule – Staged payments tied to specific milestones give you visibility and give the contractor a reason to hit those milestones on time.
A contractor who is efficient with their own costs doesn't need to pad the bid to protect themselves. That's the contractor you want, here's how to find a general contractor who meets those criteria.
