General Contractor Cost in 2026: How GCs Price Your Job
General contractor cost: most residential GCs charge a 10 to 20 percent markup on the total job, either baked into a fixed bid or added on top of cost in a cost-plus contract, and that fee pays for the part of the work you never see: scheduling, supervision, liability, and someone standing between you and twelve different subcontractors.
I've run remodels, additions, and full-gut renovations for two decades. The single most common thing I hear on a first walk-through is some version of "why does the GC cost so much when the plumber and the framer are the ones doing the work?" Fair question. So let me open the books and show you how we actually price a job, where the markup goes, and how to read a bid so you know whether you're looking at a real number or a fantasy.
What a General Contractor's Fee Actually Covers
When you hire a GC, you're not paying for hammer swinging. You're paying for the management of the project. Here's where my fee goes on a typical job:
- Estimating and bidding. Pricing a kitchen properly takes me a full day of takeoffs, sub calls, and supplier quotes. Multiply that across the jobs I bid and lose.
- Scheduling and sequencing. Framing before electrical, electrical before insulation, insulation before drywall. Get the order wrong and you're tearing out finished work.
- Hiring and managing subs. I carry a roster of plumbers, electricians, HVAC techs, and tile setters I trust. I vet them, schedule them, and chase them when they drift.
- Supervision and quality control. I'm on site catching the framing that's a half inch out of plumb before the drywall goes up and hides it.
- Liability and insurance. General liability and workers' comp cost me real money every month. That's baked into your number.
- Problem-solving. Every renovation hits a surprise: rotted subfloor, knob-and-tube wiring, a load-bearing wall that isn't on the plans. Solving those fast is the job.
If you want a deeper breakdown of the role itself, I wrote a full piece on what a general contractor actually does.
The Three Ways GCs Price a Job
There are really only three pricing structures you'll run into. Each one shifts risk between you and the contractor differently.
Fixed-Price (Lump-Sum) Bid
I give you one number for the whole job. If I estimate wrong and the job costs me more, that's my problem, not yours. If I estimate well and come in under, I keep the difference. The markup is hidden inside the total, usually 15 to 20 percent, because I'm carrying all the risk of the unknowns.
Fixed bids are clean for the homeowner and easy to compare. The downside: because I'm absorbing the risk, I pad for uncertainty. The more unknowns in your job (older house, vague plans), the more I have to pad. Vague scope plus a fixed bid is a recipe for fat change orders later.
Cost-Plus
You pay the actual cost of labor and materials, plus my fee on top. The fee is either a flat dollar amount or a percentage, usually 10 to 20 percent. I show you the invoices. There's no padding because I'm not carrying the estimating risk.
Cost-plus is the most honest structure when the scope is genuinely uncertain, like a gut renovation of a 1920s house where nobody knows what's behind the plaster. The risk to you: there's no ceiling unless you negotiate one. Always ask for a "not-to-exceed" cap so cost-plus doesn't become a blank check.
Percentage of Cost
A variation of cost-plus where my entire fee is a straight percentage of the total project cost. Simple, but it has a built-in conflict: the more the job costs, the more I make. A GC on a pure percentage has no incentive to find you savings. I'm not a fan, and you should watch for it on larger jobs.
| Pricing model | Who carries the risk | Typical markup | Best for |
|---|---|---|---|
| Fixed-price bid | Contractor | 15 to 20% (hidden) | Well-defined scope, clear plans |
| Cost-plus (with cap) | Shared | 10 to 20% (visible) | Older homes, uncertain scope |
| Percentage of cost | Homeowner | 10 to 20% (visible) | Large jobs, but watch the conflict |
Why the Markup Is 10 to 20 Percent (and What Below That Means)
People hear "20 percent markup" and assume the GC is pocketing 20 cents on every dollar. That's not how it works. Markup is not profit.
Out of that 10 to 20 percent comes my overhead: insurance, the truck, the office, the phone, fuel, the time I spend bidding jobs I don't win, and the unpaid hours managing your project. After all of that, real net profit on a residential job often lands in the 5 to 10 percent range. A GC running on a 5 percent total markup is either losing money or planning to make it back somewhere you can't see, usually inflated allowances or aggressive change orders.
This is the math behind the oldest rule in remodeling: the lowest bid is frequently the underfunded one. When a bid comes in 30 percent below everyone else, that contractor either missed scope, plans to nickel-and-dime you once you've committed, or is going to run out of money halfway and disappear. I've been called in to finish too many of those jobs. The homeowner almost always pays more than the highest original bid would have cost. I cover the warning signs in detail in my piece on the signs of a bad contractor.
Allowances: Where Bids Quietly Diverge
An allowance is a placeholder dollar amount for something you haven't picked yet. Your bid might say "tile allowance: $8 per square foot installed" or "appliance allowance: $6,000."
Allowances are legitimate. You can't always pick every finish before work starts. But they're also where bids stop being comparable. One GC pencils in a $4-per-square-foot tile allowance to make the bottom line look lean, knowing full well you're going to want the $12 tile. The other GC uses realistic numbers. On paper the first bid looks cheaper. In reality you'll blow past that allowance and owe the difference plus markup.
When you compare bids, line up the allowances first. Ask every contractor to use the same allowance numbers so you're comparing the actual work, not the optimism.
A good renovation planner helps you nail down finishes before you sign, which shrinks your reliance on allowances. I keep something like this home renovation planner and budget workbook on the kitchen table during the planning phase so the homeowner decides on paper instead of mid-demo.
Change Orders: Fair Markup vs. Padding
A change order is a written amendment to the contract when the scope changes. You decide to move a wall, or I open up a ceiling and find a leak that has to be fixed. Change orders are normal and unavoidable on most jobs.
Here's where fair markup ends and padding begins. A fair change order shows you the added cost of labor and materials, plus my normal markup percentage, in writing, with your signature before the work happens. Padding looks like:
- Change orders priced verbally, "we'll settle up at the end"
- Markup on change orders that's double the contract markup
- A flood of small change orders that signal the original scope was deliberately thin
Protect yourself with one rule: no change order proceeds without a written, signed amendment showing the price. A contractor who balks at that is telling you something. To set the project up right from the start, read my guide on how to hire a general contractor.
What a Real Bid Looks Like in 2026
A bid you can trust is itemized, not a single mystery number. It separates demolition, framing, mechanical (plumbing, electrical, HVAC), insulation, drywall, finishes, and a clearly stated allowance list. It shows the markup structure. It includes permits. And it ties payments to milestones, never a giant deposit up front.
I never ask for more than roughly 10 percent down to lock the schedule and order long-lead materials. The rest is tied to completed stages: rough-in done, drywall up, finishes complete. If a contractor wants 40 or 50 percent before lifting a tool, walk. That's not how a funded operation works. For real-world numbers on specific projects, see my home renovation cost breakdown for 2026.
The Honest Bottom Line
A general contractor's cost is the price of having one accountable person carry the schedule, the subs, the liability, and the surprises. Ten to twenty percent markup is normal and fair. Below that, somebody is either making a mistake or planning to make it up on your dime.
Read every bid line by line. Match the allowances. Demand written change orders. Tie payments to milestones. Do those four things and the markup stops feeling like a mystery and starts looking like exactly what it is: the cost of a job that actually gets finished.
