How Contractor Markup Works

Contractor markup is the percentage added to direct cost to cover everything that is not hammer time. That includes general liability insurance, workers' compensation insurance, tool and vehicle costs, office overhead, project management time, sub coordination, warranty reserves, and the contractor's profit.

Markup is not a hidden fee. It is how a contractor stays in business and honors warranty. A contractor with zero markup does not have the reserves to come back in month 10 and fix a drip or a cracked tile.

Typical US residential markup in 2026 sits at 15 to 22% for remodels and 18 to 28% for new construction. Light service work can run 20 to 35% because truck rolls and travel time eat smaller jobs.

Low markup, below 12%, is a red flag. That contractor either does not understand their cost structure or is buying the job at a loss. Both lead to cut corners and lost warranty later.

Markup is not profit. Roughly, 40 to 50% of a typical contractor's markup is insurance and overhead (rent, office staff, software, vehicles). Another 20 to 30% is project management time and sub coordination. Another 10 to 15% is warranty reserve. Actual profit to the contractor is usually 5 to 10% of revenue, less than most people assume.

• GL insurance, workers' comp, and bonding.
• Vehicles, tools, and fuel.
• Office rent, software, and admin staff.
• Project management time.
• Warranty reserves for punchlist and year-one service.
• Profit.

A fixed-price bid rolls markup into the total. The client sees one number and pays it. A cost-plus bid shows actual subs and materials at cost, plus a fixed management fee.

Cost-plus is common on bigger custom builds where the scope changes frequently. It exposes sub cost line by line. Fixed price is easier for smaller remodels because the client gets budget certainty and the contractor holds the risk of overruns. Marketplace bids lean fixed-price because comparison is easier.

Three bids with different markup approaches are hard to compare by hand. The ContractShield Work Order Marketplace normalizes bids into a common format so markup percentages and direct costs sit in the same columns. That makes a 14% markup bid with high direct cost easily comparable to an 18% markup bid with lower direct cost.

Always compare total delivered cost, then look at markup percentage to judge the contractor's reserve for warranty and punchlist. Neither number alone tells the full story.

Three mistakes show up over and over: treating low markup as a win, pushing for cost-plus on small jobs, and ignoring markup altogether. Low markup starves warranty. Cost-plus on small jobs creates more admin than value. Ignoring markup hides the comparison entirely.

Use markup as a signal of contractor health, not as something to negotiate away.
